                  House of Representatives,
                       Committee on Armed Services,
                          Subcommittee on Strategic Forces,
                         Washington, DC, Wednesday, April 30, 2025.
    The subcommittee met, pursuant to call, at 3:01 p.m., in 
room 2118, Rayburn House Office Building, Hon. Scott DesJarlais 
(chairman of the subcommittee) presiding.

 OPENING STATEMENT OF HON. SCOTT DESJARLAIS, A REPRESENTATIVE 
   FROM TENNESSEE, CHAIRMAN, SUBCOMMITTEE ON STRATEGIC FORCES

    Dr. DesJarlais. Today's hearing will come to order.
    Pursuant to committee rule 4(b), three members of the House 
Armed Services Committee who are not members of the 
subcommittee are allowed to participate in today's hearing and 
will be recognized after all subcommittee members have had an 
opportunity to ask questions.
    Good afternoon, and welcome to the Strategic Forces 
Subcommittee's hearing on missile defense and defeat programs 
of the Department of Defense.
    Testifying before the subcommittee today, we have Ms. 
Andrea Yaffe, who is currently performing the duties of the 
Assistant Secretary of Defense for Space Policy; we have 
General Gregory Guillot, Commander of U.S. North Command and 
North American Aerospace Defense Command; Lieutenant General 
Heath Collins, Director of Missile Defense Agency; and 
Lieutenant General Sean Gainey, Commander, U.S. Army Space and 
Missile Defense Command and Joint Functional Component Command 
for Integrated Missile Defense.
    Thank you to our witnesses for being with us today.
    We recognize the fiscal year 2026 budget is still being 
finalized and this limits our ability to discuss funding levels 
for the upcoming fiscal year. However, we look forward to 
hearing from you on the policies, programs, and priorities for 
the Department for missile defense and missile defeat 
activities. Your testimony today will help set the stage for 
our review of the President's budget when it is submitted.
    We also forward to hearing an update from our witnesses on 
the Department's work to develop the Golden Dome for America's 
architecture.
    Today's hearing comes at an important moment for missile 
defense. Despite the growth and increasing complexity of 
missile threats in recent years and the value of missile 
defense capabilities being demonstrated in the skies over 
Israel, the Red Sea, and Ukraine, budget requests for missile 
defense funding in recent years have declined.
    Last year's budget, in particular, prematurely eliminated 
competition in two key missile defense programs, the Glide 
Phase Interceptor and Next-Generation Interceptor, and also 
proposed to terminate procurement of the Navy's Standard 
Missle-3 block Intermediate-range ballistic missile 
interceptor. Each of these decisions added risk and sacrificed 
capability for the sake of reducing funding on missile defense.
    Now, a new administration has taken office, with a new 
vision for investment in missile defense capabilities and 
defending the homeland that is long overdue.
    Missile threats to the homeland are growing and becoming 
more dynamic as our adversaries develop and deploy new 
capabilities, such as hypersonic weapons, long-range cruise 
missiles, new ballistic missiles, and even Fractional Orbital 
Bombardment System, or FOBS.
    These capabilities enable our adversaries to strike the 
United States and coerce U.S. leadership in the event of 
crisis, and our ability to defend against them has not kept 
pace. Sustained underinvestment and outdated policy limitations 
have left our homeland vulnerable.
    In its 2023 report, the bipartisan Congressional Commission 
on the Strategic Posture of the United States, led by Madelyn 
Creedon and former Senator Jon Kyl, noted our homeland's 
vulnerability, stating: ``Russia and China are deploying 
missile defense systems designed to protect critical assets 
against U.S. offensive strikes. To date, the United States has 
chosen not to build homeland missile defenses against major 
powers. U.S. homeland integrated air and missile defense 
capabilities do not adequately protect the critical 
infrastructure necessary to project power and avoid coercion in 
light of growing Russian and Chinese nuclear and conventional 
strike threats.''
    The Commission went on to recommend the deployment of a 
comprehensive integrated air and missile defense system capable 
of deterring and defeating coercive attacks from Russia and 
China as well as rogue states. And it argued doing so would 
strengthen deterrence and reinforce strategic stability by 
complicating adversary planning and reducing incentives to 
conduct coercive attacks.
    While I expect we will see significant partisan debate 
about the Golden Dome, it is important to remember the common 
sense, bipartisan elements at the core of the President's 
vision, and I look forward to seeing the Department's plan for 
carrying it out.
    I now recognize the ranking member, my friend Mr. Moulton, 
for his opening remarks.

     STATEMENT OF HON. SETH MOULTON, A REPRESENTATIVE FROM 
MASSACHUSETTS, RANKING MEMBER, SUBCOMMITTEE ON STRATEGIC FORCES

    Mr. Moulton. Thank you, Chairman DesJarlais.
    And thank you, again, to all our witnesses for your 
testimony today. This is esoteric but unbelievably important 
work, and we appreciate your dedication to our Nation's 
strategic defense.
    As I have said repeatedly, missile defense has a mixed 
legacy, but let's start with the vast areas where my colleagues 
and I and most experts agree. And I am fortunate--because this 
is so esoteric--to be accompanied this afternoon by this nifty 
chart I developed.
    We have pursued robust investments in sensing and tracking, 
the foundational basis of missile defense, including the Golden 
Dome idea. And we are doing more. That is level one.
    We have also matured reasonable missile defense 
capabilities that are truly miracles of engineering--Patriot, 
Aegis, THAAD (Terminal High Altitude Area Defense)--that have 
real battlefield benefit today to our allies and partners under 
attack. Level two.
    We have sought to defend fully against the strategic threat 
posed by rogue nations, such as North Korea, who may not be 
deterred by mutually assured destruction. That is level four.
    And I am skipping over level three very quickly, but that 
is because it is essentially similar to level four, which is if 
one of these nations or a Russia or a China simply has an 
accidental launch.
    In either case, we are talking about a small number of 
missiles that can be defeated by existing missile defense 
systems and missile defense systems that have been developed 
since Bush pulled out of the Anti-Ballistic Missile Treaty.
    However, we have relied on our nuclear deterrent or the 
concept of mutually assured destruction when it comes to the 
huge, complex threats posed by Russian and Chinese 
Intercontinental Ballistic Missiles, hypersonic, and other 
systems that are specifically designed to evade our missile 
defense. That is level five.
    So, as the chairman correctly pointed out, there are a lot 
of areas of bipartisan agreement here. And the question is, 
what do we do about level five? Because that is what the 
President is proposing changing.
    Now, as stated in the 2019 Missile Defense Review authored 
by the first Trump administration, and I quote, ``The United 
States relies on nuclear deterrence to address the large and 
more sophisticated Russian and Chinese intercontinental 
ballistic missile capabilities as well as to deter attacks from 
any source consistent with longstanding U.S. declaratory 
policy.''
    To be clear, Golden Dome completely upends this policy, 
which is credited with keeping us safe from nuclear attack for 
the last 70 years.
    Do we believe that the fundamentals of the strategic 
landscape in the past 6 years have shifted so dramatically that 
we require a monumental shift in our strategic defense policy, 
a shift from every prior Democratic and Republican 
administration, including the first Trump administration?
    If so, I am more than happy to hear why and entertain that 
debate. But, so far, we have not heard why. We have not heard 
any rationale. We have not heard any plan.
    And here is why this could be dangerous. The goal of 
missile defense, of course, is to keep us safe. But, 
paradoxically, more missile defense is not necessarily better 
if it upsets strategic stability, the equilibrium that deters 
any nation from launching a nuclear attack that could explode 
into a nuclear war.
    Most people don't know how close we have come to nuclear 
war by accident in the last 70 years, but we have had 13, at 
least 13, close calls, like the time when the Soviet systems 
detected a massive U.S. attack and a lowly Russian major only 
averted a nuclear holocaust by suspecting it was a false 
indication and deliberately disobeying a standard order to 
launch a retaliatory attack.
    Part of why he relied on his intuition in that instance is 
knowing that his own people, his own family, would be 
obliterated if he got that wrong. That is why mutually assured 
destruction, an assuredly frightening concept, actually 
promotes stability. If nations know that they will, themselves, 
get obliterated if they use nuclear weapons, they are unlikely 
to use nuclear weapons.
    The potentially devastating problem with Golden Dome is 
that it upends this strategic stability. And if Russia or China 
believes, instead, that the United States is not so vulnerable 
to a retaliatory strike, it makes them less likely to think 
twice about acting quickly, acting first, or using novel 
delivery methods to get around our defenses, including Golden 
Dome itself, before we do anything to them. And that is why, 
even though Golden Dome sounds good, it could actually make us 
less safe.
    I fear that some of my colleagues who tout their fiscal 
responsibility want to spend billions of taxpayer dollars 
without a plan and, worse, on something that could actually 
make those very taxpayers less safe and our Nation less secure. 
That is neither fiscal nor strategic responsibility.
    Sadly, as with most complex national-security issues, the 
President understands neither the history nor the implications 
of these plans. He just wants to one-up one of his friends with 
a gold-plated version of something they have.
    So, as we continue to evaluate DOD missile defense 
programs, I will ask these questions: How will expanding U.S. 
missile defense today impact our strategic stability tomorrow? 
Does it raise the incentive for our adversaries to strike 
first? We are already in an arms race; will this accelerate it? 
Do these choices make our Nation and our world more or less 
safe?
    These are the questions we must ask ourselves on this 
subcommittee, not just with an eye to this year's budget and 
the National Defense Authorization Act but with a view towards 
how our decisions will impact the world we leave for our 
children.
    Let me be clear once again: It is the job of this committee 
to have this debate, to investigate whether something has 
changed with technology or our adversaries or otherwise, and 
provide the oversight that we are constitutionally required to 
provide. What is not our job is to fund a fantasy, especially a 
dangerous one.
    Thank you, Mr. Chairman. I yield back.
    Dr. DesJarlais. I thank the ranking member for his comments 
and would agree that this is a good subject for debate today.
    You speak that, 6 to 8 years ago, how things have radically 
changed or not changed. And, as we know, fielding these 
defenses takes time and you have to be also looking into the 
future. So, I think those are fair questions, and we will get 
through those today.
    We will now move to the opening statements from our 
witnesses.
    I would note that your prepared statements will be made 
part of the record, but you will each have 5 minutes to make 
opening remarks.
    Ms. Yaffe, let's begin with you. And after you, I will 
recognize General Guillot, General Collins, and General Gainey.
    You are now recognized.

    STATEMENT OF ANDREA YAFFE, PERFORMING THE DUTIES OF THE 
ASSISTANT SECRETARY OF DEFENSE FOR SPACE POLICY, OFFICE OF THE 
                      SECRETARY OF DEFENSE

    Ms. Yaffe. Thank you.
    Chairman DesJarlais, Ranking Member Moulton, and 
distinguished members of the committee, thank you for inviting 
me to testify on the Department of Defense's missile defense 
and defeat posture. I am grateful to appear alongside my 
distinguished colleagues.
    Missile defenses are a vital element of our strategic force 
posture, both as a means of deterrence as well as defending the 
U.S. homeland and our security interests abroad.
    As we see nearly every day in conflicts worldwide, 
offensive missile capabilities are becoming a central feature 
of modern warfare. China, North Korea, Russia, and Iran now 
deploy advanced missile systems to coerce and intimidate 
opponents, inflict tactical damage, or to carry out strategic 
campaigns. Our adversaries are investing in the next generation 
of offensive capabilities to hold the United States homeland at 
risk, coerce our allies and partners, and threaten our deployed 
forces.
    China, Russia, and North Korea are fielding more advanced 
missiles with greater ranges and in larger numbers to provide 
the means for strategic-level attack against the homeland, 
including nuclear and conventional options. These adversaries 
are rapidly modernizing, expanding, and diversifying their 
missile forces, incorporating technological advances into 
warheads, delivery systems of all types, and supporting command 
and control systems.
    Iran, meanwhile, has the capability to strike targets 
throughout the Middle East and continues to arm its proxies in 
the region.
    The President's Golden Dome for America executive order 
underscores this point. The threat of attack by ballistics, 
hypersonic, and cruise missiles and other advanced aerial 
attacks remain the most catastrophic threat facing the United 
States. To counter these growing threats, we need next-
generation missile defense and missile defeat architectures 
that can complement our existing nuclear and conventional 
offensive capabilities.
    The President has directed that the United States will 
develop and field a next-generation missile defense shield to 
provide for the common defense of our citizens and the Nation 
and deter, defend against, and defeat any foreign aerial attack 
on the homeland. We will also guarantee our secure second-
strike capability.
    Golden Dome is a top priority for the Nation and will 
include the development of cutting-edge domain awareness 
systems, kinetic and non-kinetic missile defeat capabilities, 
and advanced command, control, and battle management systems to 
integrate and augment existing U.S. missile defense 
capabilities.
    The Department of Defense remains committed to making the 
necessary investments in our posture to deter our adversaries 
and, if deterrence fails, to prevail in conflict. The Office of 
the Under Secretary of Defense for Policy is working together 
across the Department, including with my colleagues here today, 
to make good on these investments to defend our homeland and 
our forces.
    Thank you for the opportunity to testify, and I look 
forward to answering your questions.
    [The prepared statement of Ms. Yaffe can be found in the 
Appendix on page 34.]
    Dr. DesJarlais. Thank you.
    General Guillot, you are recognized.

   STATEMENT OF GENERAL GREGORY M. GUILLOT, COMMANDER, U.S. 
 NORTHERN COMMAND AND NORTH AMERICAN AEROSPACE DEFENSE COMMAND

    General Guillot. Good afternoon, Chairman DesJarlais, 
Ranking Member Moulton, and distinguished members of the 
subcommittee. Thank you for holding this important hearing.
    Both North American Aerospace Defense Command and the 
United States Northern Command have critical roles in defending 
North America from missile attack, and we appreciate the 
subcommittee's continued support of our efforts.
    I would also like to recognize the tremendous work being 
done by Lieutenant General Collins, Lieutenant General Gainey, 
and Assistant Secretary of Defense Yaffe. As the supportive 
commands for homeland missile defense, North American Aerospace 
Defense Command and United States Northern Command are 
fortunate to have such strong and committed partners in our 
shared, no-fail mission.
    Defending North America from missile threats is 
increasingly challenging, as global competitors rapidly develop 
and field advanced missile capabilities and delivery platforms, 
aided by increasing cooperation and technology-sharing between 
the competitors.
    To counter such adversary cooperation, North American 
Aerospace Defense Command and United States Northern Command 
rely on realistic planning, targeted investments, timely 
deliveries, and forward-looking policies that ensure the 
commands' ability to detect, track, and defeat potential 
threats in all domains.
    Establishing a layered domain awareness network to detect 
and track threats approaching North America from seabed to 
space remains our top priority, because you can't defeat what 
you can't see. That network is central to the current and 
future North American Aerospace Defense Command and United 
States Northern Command requirements, which certainly include 
the Golden Dome for America construct.
    Along with improved domain awareness, we must also improve 
our capability and capacity to defeat missile threats. On-time 
delivery of the Next-Generation Interceptor is necessary to 
counter North Korea's growing Intercontinental Ballistic 
Missile fleet. And innovation and investment in advanced defeat 
mechanisms, which could include directed energy, left of 
launch, and boost-phase intercept, are needed to defeat cruise 
missiles, hypersonics, and other advanced threats.
    There are significant challenges ahead of us, but North 
American Aerospace Defense Command and United States Northern 
Command's capability and resolve to deter aggression and defeat 
threats to our Nation remains unshakeable.
    Thank you again to the subcommittee and my fellow witnesses 
for your continued support. I look forward to your questions. 
We have the watch.
    [The prepared statement of General Guillot can be found in 
the Appendix on page 46.]
    Dr. DesJarlais. Thank you, sir.
    General Collins?

  STATEMENT OF LIEUTENANT GENERAL HEATH A. COLLINS, DIRECTOR, 
                     MISSILE DEFENSE AGENCY

    General Collins. Thank you.
    Good afternoon, Chairman DesJarlais, Ranking Member 
Moulton, distinguished members of the subcommittee. Thank you 
for this opportunity to talk about missile defense and thank 
you for your continued support of missile defense and the 
broader missile defense enterprise.
    The Missile Defense Agency is moving quickly to provide 
effective defenses against a dangerous missile threat to defend 
the U.S. homeland, our deployed forces, and our allies and 
friends. The Agency is transforming itself, its enterprise, and 
its industry base in order to develop and deliver capabilities 
to the warfighter at speed and scale.
    As we move with urgency to deliver the next-generation 
missile defense system, we intend to leverage the performance 
efficiencies found in an integrated, layered missile defense. 
We also will continue to exploit the space domain to support a 
missile defense posture that is more effective, resilient, and 
adaptable to known and anticipated threats.
    Missile Defense Agency is laser-focused on improving our 
U.S. homeland defenses. We are enhancing the performance and 
capability of the fielded Ground-Based Midcourse Defense 
system, along with developing and testing of the new Next-Gen 
Interceptor.
    In support of regional defense, we are working with the 
Navy to improve Aegis ballistic missile defense capability and 
enhance hypersonic defenses and with the Army to make 
investments in the future development of the Terminal High-
Altitude Area Defense system, Terminal High Altitude Area 
Defense.
    In support of the Nation's missile defense enterprise, 
Golden Dome for America, and reestablishing deterrence, Missile 
Defense Agency remains focused on delivering advanced, 
reliable, and resilient capabilities on accelerated timelines 
to meet the warfighters' needs.
    I greatly appreciate your continued support of Missile 
Defense Agency and the missile defense mission, and I look 
forward to answering your questions. Thank you.
    [The prepared statement of General Collins can be found in 
the Appendix on page 71.]
    Dr. DesJarlais. Thank you.
    General Gainey?

  STATEMENT OF LIEUTENANT GENERAL SEAN A. GAINEY, COMMANDING 
      GENERAL, U.S. ARMY SPACE AND MISSILE DEFENSE COMMAND

    General Gainey. Thank you.
    Chairman DesJarlais, Ranking Member Moulton, and 
distinguished members of the subcommittee, I am honored to 
testify before you as the Commander of U.S. Army Space and 
Missile Defense Command and Joint Functional Component Command 
for Integrated Missile Defense.
    In these roles, I am representing an incredible 
organization of 2,300 soldiers and civilians spanning 13 time 
zones and 19 locations worldwide. The ``one team'' of 
professionals, along with this Army and joint air and missile 
defense forces, provide credible combat capability so important 
to our peace-through-strength deterrence approach and support 
to three combatant commanders.
    I also serve as the senior commander for Fort Greely, 
Alaska, and senior responsible officer for U.S. Army Kwajalein 
Atoll--two strategic locations, remote sites that are 
experiencing challenges with facilities and we must continue to 
address with priority.
    Additionally, I also serve as our Army's lead enterprise 
integrator for air and missile defense. As the Army air and 
missile defense enterprise integrator, just as I did last year, 
I want to highlight the strain on our Army Missile Defense 
force. High deployment operation tempo and frequent deployment 
extensions not only create challenging conditions for our 
soldiers and their families but place the Army's modernization 
plans at risk, as continual extensions jeopardize critical 
upgrades.
    The deployment-to-time-at-home ratio for Army air and 
missile defense units is nearly one-to-one, well below the 
Department of Defense goal. Air Defense Artillery is the most 
deployed force in the Army.
    In response, the Army leadership has increased military 
occupational specialty recruiting flexibility through the 14 
Uniform military occupational specialty pilot program and added 
critical skill bonuses, increased training opportunities, and 
built-in station-of-choice incentives, essentially improving 
accessions.
    Further addressing the operation tempo challenge, the Army 
Integrated Air and Missile Defense is undergoing the most 
significant modernization in history, fielding the Integrated 
Battle Command System. This will fundamentally change the way 
sensors and shooters are integrated across the battlefield, 
increasing capacity and depth to achieve an outsized effect. 
And, finally, the Army Air Defense Artillery force structure 
will increase by 39 percent by fiscal year 2030.
    You have already heard much about the dynamic, evolving 
threat. It is clear we are now entering a new air and missile 
age. With these threats in mind, Space and Missile Defense 
Command is advancing an air and missile defense strategy for 
tomorrow while continuing to develop outsized value today.
    Our Space and Missile Defense Command Center of Excellence 
supports the training, lethality of--the schoolhouse for our 
space and missile defense soldiers.
    Our Technical Center is advancing cutting-edge technologies 
in directed energy, space, high-altitude and hypersonic 
testing, enabling domain dominance and non-kinetic alternatives 
within a comprehensive missile defeat framework.
    It also manages the Ronald Reagan Ballistic Missile Defense 
Test Site, which is critical for testing and domain awareness, 
ideal in location and unmatched in precision instrumentation.
    Joint Functional Component Command for Missile Defense 
conducts transregional missile defense planning and operational 
support, capability assessment, and joint education training, 
all aligned under the U.S. Space Command.
    I will focus my final point on the holistic air and missile 
defense approach. Simply put, Space and Missile Defense Command 
is already engaged. We man, train, and equip the soldiers 
providing protection against intercontinental ballistic 
missiles right now, and we are actively managing network 
architecture for the air defense in place over the national 
capital region.
    However, we must continue to leverage technology to 
transform our missile defense capabilities to address the 
current and future threat, and Space and Missile Defense 
Command has the expertise and experience to add even more value 
in the future. We must also invest in left-of-launch 
capabilities in a holistic missile defeat approach.
    In conclusion, I have seen firsthand how every member of 
our ``one team'' at Space and Missile Defense Command 
contributes to the security of our homeland. Every day brings a 
new challenge and opportunity. From our missile defense battery 
in United States Central Command to our Fire Direction Center 
in Alaska, our team is globally lethal, always ready.
    And I look forward to addressing your questions. Thank you.
    [The prepared statement of General Gainey can be found in 
the Appendix on page 93.]
    Dr. DesJarlais. Thank you all for your very sobering and 
important opening statements.
    I will now turn to member questioning that will recognize 
each member for up to 5 minutes, and I will start by 
recognizing myself.
    While I understand that the final architecture for Golden 
Dome remains under review, it would be helpful to hear from 
each of you how your organizations have contributed to the 
plans so far.
    And, General Guillot, let's begin with you.
    General Guillot. Chairman, thank you.
    As you mentioned, we still don't know the final 
configuration, but North American Aerospace Defense Command and 
United States Northern Command, as separate commands, provided 
input to both the Office of the Secretary of Defense and Joint 
Staff in terms of, as the supportive command, what capabilities 
we would need from a Golden Dome approach.
    And what we provided, sir, were three separate layers. 
First is a domain awareness layer that detects all threats from 
seabed to space, to include the air and terrestrial layers in 
between, that are integrated to feed two defeat layers, the 
first being an intercontinental ballistic missile defeat layer, 
which largely exists today with the ground-based interceptors 
that can defeat a North Korean threat, and then an air layer 
that would defeat cruise missiles and air threats.
    The challenge, I think, is the hypersonic, which at 
different parts of their flight profile could be in the 
intercontinental ballistic missiles phase or the air phase. And 
so making sure that the detect and track capability was 
flexible enough to handle hypersonics.
    And then, of course, the defeat mechanisms as well.
    Dr. DesJarlais. Okay.
    General Collins?
    General Collins. Thank you, Mr. Chairman.
    So the Missile Defense Agency, as you can imagine, we have 
been working on a national missile defense architecture for 42 
years. And so we certainly have been a big part of playing--and 
as the integrated missile defense tech authority as well, we 
were a key part of the team supporting what it takes to put 
together an integrated missile defense system.
    And both what we have been doing, the analysis that we have 
conducted over many decades--and we are at the core of helping 
support and inform the Department in putting together an 
architecture that is comprehensive, that covers all pieces and 
parts, and could be executable.
    Dr. DesJarlais. General Gainey?
    General Gainey. I, as the Commander of Space and Missile 
Defense Command, have not personally been involved with the 
architecture build. I am more of the operational side when it 
comes to implementation.
    However, our team continues to man the ground-based 
interceptors and are prepared to support United States Northern 
Command in any capacity moving forward.
    Thank you, sir.
    Dr. DesJarlais. Thank you.
    And Ms. Yaffe?
    Ms. Yaffe. Thank you.
    Given the whole-of-Department nature of this problem set 
and the expansive vision, the Office of the Secretary of 
Defense for Policy joined with Joint Staff early in the days of 
receiving the executive order to try to convene the core 
elements of the Department, the experts, the stakeholders, to 
help frame it in terms of what the Department would need to do, 
lay out the requirements, make sure that we understood the 
guidance from the White House, and start building out different 
options. We certainly turned it to the technical folks to dig 
in and build the architecture from there. But this is an all-
encompassing problem, and the Office of the Secretary of 
Defense for Policy helped in the early days to coordinate it.
    And once we have a decision on the architecture, the 
intention is to go to phase two and to lead and conduct a 
theater missile defense review, as that will be important, as 
well as just broader considerations of strategic requirements.
    Thank you.
    Dr. DesJarlais. Thank you.
    General Guillot, can you talk about how the threats were 
considered in this process?
    This isn't just building capability for the sake of 
capability; this is based on evolving threats to the homeland. 
And I think it is interesting, we talked about what it was 6 
years ago, what it is today, and what you expect it to be. And 
from your opening statements, you know, obviously, there is 
great concern.
    So can you just talk about how you went about this?
    General Guillot. Chairman, we did use the threat as the 
basis for our requirements that we put forward, certainly 
starting with the intercontinental ballistic missile threat 
that we see from North Korea and that we could potentially see 
from Iran should they decide to take their space-launch vehicle 
and turn that into an intercontinental ballistic missile.
    Then the hypersonic threat, which, as I mentioned a moment 
ago, kind of goes through both the intercontinental ballistic 
missile portion, depending on how it is launched, all the way 
through a terminal phase challenge for us.
    And then the air threat, which certainly over the last 6 
years, as you mentioned, has increased, as we look at both 
Russia and China and their doctrine which says they will use 
cruise missiles to hit various points of critical 
infrastructure for us.
    And making sure that those were all tied together with a 
sensing grid that could detect and track and feed the defeat 
mechanisms. And then ensure that we have the right command and 
control system where we could seamlessly go from one of the 
layers to another with one operator to make sure we are 
defeating those threats.
    Dr. DesJarlais. Okay.
    My time has expired, and I will now recognize the ranking 
member, Mr. Moulton, for 5 minutes.
    Mr. Moulton. Thank you very much, Mr. Chairman.
    General Collins, given what we have heard from industry, is 
it accurate that space-based interceptors would be deployed in 
low Earth orbit?
    General Collins. Sir, we have not finalized what the space-
based interceptor architecture would be. We are going to open 
it up to industry. I fully expect that part of that would be in 
the low-earth orbit environment, sir.
    Mr. Moulton. Okay. It is hard to imagine where else that 
would be.
    General Guillot, would you agree with that assessment?
    General Guillot. Yes, sir, I would.
    Mr. Moulton. Okay.
    Ms. Yaffe, have Russia and/or China publicly or privately 
expressed concerns with U.S. missile defense systems posing 
strategic stability concerns with regards to second-strike 
capabilities?
    Ms. Yaffe. Sir, I think the Russians are on the record for 
many years expressing concerns about missile defense, at the 
same time as they build their own capabilities.
    Mr. Moulton. Yeah. The Chinese have as well.
    So, given General Collins's response regarding a space-
based intercept architecture being placed in low-earth orbit, 
as General Guillot affirmed, would it be susceptible to effects 
of a nuclear detonation in that orbit?
    Ms. Yaffe. Sir, were there to be a nuclear detonation in 
low-earth orbit, then perhaps it would be. Obviously, all the 
folks involved in the architecture discussions are tracking the 
threats--
    Mr. Moulton. Yeah. So, with what we know about Russia's 
efforts to develop and deploy a nuclear weapon in space and 
their fear of U.S. missile defenses, has there been an 
assessment done on the likelihood or increased chance that 
Russia would employ such a weapon in conflict early on to take 
out our space-based intercept layer?
    Ms. Yaffe. Sir, that sounds like an intelligence 
assessment, and I would defer that to the intelligence 
community.
    Mr. Moulton. No, no, no. It is an operational question. You 
are going to spend billions of dollars of taxpayer money 
building things that could inspire the Russians to say, ``Oh, 
we need to take them out before they get used.'' You better 
figure that out if you are going to spend a lot of taxpayer 
money on this.
    Ms. Yaffe. Sir, I understand the question. I think we have 
seen that Russia is pursuing its capabilities in any case given 
the threats that they see broadly. However, they also continue 
to counter these threats with their own missiles, which is--
    Mr. Moulton. Well, I will tell you what; you better figure 
it out. If you are going to build this whole thing, at the cost 
of tens of billions of dollars in taxpayer money, and then the 
Russians just plan to take it out with their space-based nuke, 
that is not going to work too well for anybody, because, of 
course, it is going to take out all the rest of our satellites 
as well.
    Ms. Yaffe, you also used a word today that I have not heard 
before when describing Golden Dome, ``aerial.''
    Is it, indeed, the President's vision to only defend 
against aerial threats, like the Iron Dome system where he got 
this idea? So, in other words, all China needs to do is develop 
the kinds of sea-based delivery systems Russia started 
developing after we pulled out of the Anti-Ballistic Missile 
Treaty just to get around Golden Dome?
    Ms. Yaffe. No, sir. The executive order calls for the 
defense of the United States against ballistic, hypersonic, 
advanced cruise missiles, and other next-generation aerial 
attacks. The earlier part of--
    Mr. Moulton. Aerial attacks.
    Ms. Yaffe. Correct. Other next--
    Mr. Moulton. So not sea-based.
    Ms. Yaffe. I mean, a sea-based ballistic missile would be 
part of this.
    Mr. Moulton. As we all know, there are other ways you can--
you can run a boat up into Los Angeles Harbor, right? It is 
clear that Golden Dome is not designed to defend against that.
    Is that your understanding as well, General Guillot, since 
``aerial'' is in the executive order?
    General Guillot. Yes, it is.
    Mr. Moulton. Okay. That seems like another big hole we 
should investigate before we spend a lot of money on this.
    General Guillot, given your responsibilities as the 
Commander of Northern Command, do you believe that the 
strategic landscape has significantly changed in the past 6 
years such that the second Trump administration would 
dramatically change its strategic defense policy from the first 
Trump administration?
    General Guillot. Congressman, I do think that the landscape 
has changed significantly, with the number of countries that 
are either possessing or pursuing intercontinental ballistic 
missiles, the hypersonics--
    Mr. Moulton. Are you talking about China? Because we knew 6 
years ago that China was doing this.
    General Guillot. No. I am talking about Iran's pursuit and 
Pakistan's pursuit.
    Mr. Moulton. Okay. Well, Iran and Pakistan have been 
pursuing those things for a long time.
    General Guillot. Well, yes, sir, but they are certainly 
more advanced now than they were 6 years ago.
    Mr. Moulton. Well, apparently we are going to get rid of 
Iran's nuclear capabilities with a deal, so I guess they are 
going to be off the table. Of course, we have had a way of 
dealing with Pakistan for a while.
    General Gainey, what is our pacing threat right now 
according to the National Defense Strategy?
    General Gainey. The North Korean threat.
    Mr. Moulton. Actually, it is the Chinese threat.
    So, given that we are conducting a shift to the Pacific, 
how does moving Terminal High Altitude Ariel Defenses and 
Patriot batteries out of the Pacific into the Middle East help 
support our National Defense Strategy?
    General Gainey. Any movement of any of our Patriot or 
Terminal High Altittude Ariel Defense systems are taken under 
careful consideration. And we also have additional assets at 
home station prepared to deploy and fill those voids, if 
necessary. But every deployment is carefully considered as part 
of our Global Force Management Allocation Plan.
    Mr. Moulton. Thank you, Mr. Chairman.
    Dr. DesJarlais. The chair now recognizes the gentleman from 
Nebraska, Mr. Bacon, for 5 minutes.
    Mr. Bacon. Thank you, all four of you, for being here.
    I was fortunate to do missile defense in Israel in 2009 and 
2010. We worked with the Arrow missile team, put in a radar 
satellite support. And I would never have thought that we could 
shoot down 99 percent of 110 ballistic missiles and then, 
later, 180 ballistic missiles at a 99 percent probability of 
kill.
    So thank God for missile defenses. Israel has seen the 
impact of a system that works. And, granted, we have a 
different problem set; we are a lot bigger. But I think our 
country will be well-served to have a strong missile defense as 
well.
    My first question is to General Guillot.
    I am a little worried about some of the cuts in our 
National Guard. Your predecessor had some concerns, too, about 
having enough aircraft to do the alerts.
    How does the air portion of this mission fit in with Golden 
Dome? I mean, is it--you would think it would be more radars 
and interceptors, but I think aircraft play a role too.
    General Guillot. Congressman, I think you are exactly 
right. As we envision the entire network, it would include 
space-based AMTI, airborne moving target indicator, which would 
detect and track aircraft and cruise missiles; a land-based 
capability, such as over-the-horizon radar; and certainly 
fighter aircraft with capable interceptors, missiles, to defeat 
cruise missiles.
    Which, in addition to the ranking member's question that I 
answered on intercontinental ballistic missiles, I think cruise 
missiles is probably the biggest advancement that we have seen 
--
    Mr. Bacon. Yeah.
    General Guillot. --over the past 6 years, and that needs to 
be a part of this integrated system.
    Mr. Bacon. Do you get a voice when the services are looking 
at reductions? Because your predecessor had expressed concern 
on the reductions with the Air National Guard, and they are the 
ones who are providing the alert capabilities. Do you feel well 
enough coordinated with? And is your comfort zone good right 
now with what we have?
    General Guillot. Yes, sir, to both. I do get a voice, and I 
am very comfortable with the Air National Guard's presentation 
for our alert force.
    Mr. Bacon. Okay. Thank you.
    General Collins, yesterday, we voted on a $150 billion 
plus-up to our defense spending. We want to get us to about 4-
percent-of-GDP spending, which is the norm. Right now, we are 
at 2.9 percent. That is inadequate for all systems we want to 
field plus taking caring of our troops. So I am excited about 
what we are going to be able to do this next year to right-size 
our defense spending.
    I think we are going to be spending $5.6 billion on missile 
defense with the money that we apportioned. What do you think 
are the first steps for you, and what do you need to field for, 
like, space inceptors and things like that? What is your first 
priority with this influx of money?
    General Collins. Thank you for that, Congressman. We 
certainly do see the opportunity of a reconciliation to begin 
quickly and bring much-needed resources into the missile 
defense enterprise.
    It really is probably not just one thing. I think there are 
really, I think, two lanes to look at when we look at the 
missile defense enterprise.
    And number one is making sure we have the capability/
capacity with the kit we have today to improve the defense 
posture today or as quickly as we can. We can make a difference 
today with systems that we have.
    And then the second piece would be really looking at the 
disruptive technology piece and pushing on that development 
piece and getting into an agile prototyping construct as 
quickly as possible, whether that be directed energy, non-
kinetics, or space-based interceptors. And I think we would 
look to do a very heavy cyclical prototyping phase to get after 
that and mature that capability as quickly as possible.
    Mr. Bacon. But it would seem to me you would have to have a 
really good sensor system first before you can intercept. And 
that is something we have talked about before. Obviously, 
ballistic missiles from the sea, from the continent, but the 
hypersonics are very hard to track. And so I would see a real 
need there to really work on the sensor problem first.
    General Collins. Yes, sir. Much of the kit that we have 
today, we certainly have proven sensor architectures to track 
ballistic missiles today, ground-based.
    And we are 1 year into our prototyping experiment with the 
HBTSS, the Hypersonic and Ballistic Tracking Space Sensor, 
which has been going very well and showing very positive 
performance against the hypersonic threat. And so, as part of 
that, we would look to then expand that.
    The Space Force and the Space Development Agency already 
had a plan to integrate the hypersonic and ballistic tracking 
space sensor into the proliferated warfighting space 
architecture. We would look, with additional resources, to 
accelerate that as much as possible to bring that capability to 
bear.
    Mr. Bacon. Thank you so much. And even if we have differing 
opinions on the actual missile defense, it seems like the 
sensor stuff is something we could all agree to and we need.
    With that, I yield.
    Dr. DesJarlais. The gentleman yields back.
    The chair now recognizes the gentleman from California, Mr. 
Whitesides.
    Mr. Whitesides. Thank you, Mr. Chairman.
    Thanks for your service and for being here today.
    General Gainey, I was struck by your comments about the 
challenges on the deployed folks. And I recently got back from 
the Middle East, from a trip. We went to Iraq and various Gulf 
nations and met with troops who are working on some of these 
missile defense things over there. They are doing heroic work.
    What could Congress do to help this challenge for these 
deployed folks? You referred to one program in your testimony, 
but I just wanted to give you the chance to elaborate a little 
bit further on this issue.
    General Gainey. Yes, sir. Thanks for asking that question.
    The air and missile defense force is a very resilient 
force. And we have asked a lot of our force, and they continue 
to respond, as you saw in the Middle East.
    Where Congress can support is continue to support the 
funding of our air and missile defense modernization. Our 
modernization is going to allow us to not completely rely on 
our Patriot system as the system of choice but also field out 
our Integrated Battle Command System, which will integrate our 
counter-cruise-missile capability into our common C2 construct, 
and so, therefore, the Patriot system is not the only system 
that we will have to rely on for the range of threats. It will 
give us the portfolio to have the appropriate shooter for the 
appropriate threat set.
    Mr. Whitesides. Okay. Thanks.
    So, actually, building on that, you know, one of the things 
that we heard throughout the Middle East was, everybody is just 
super-eager to get more of our missile defense equipment, you 
know. And they are frustrated, honestly, by how long it takes 
for our American industrial base to produce that stuff.
    This is a question for maybe General Collins, or, I don't 
know, General Guillot, you may have comments as well.
    What is going on? How could we improve that? You know, we 
are talking about folks taking 10 years to get systems that 
they have, you know, ordered, or, you know, 5 to 10 years. What 
are the underlying challenges? How could Congress help? What 
does American industry need to do to do better on that 
production side?
    General Collins. Thank you, Congressman, for that question.
    It is certainly a challenge that we continue to face with, 
especially, new developments, developments of capability that 
starts from scratch, that does not exist. And some of those do 
take a considerable amount of time.
    There are certainly activities to focus on more mature 
technologies as you start the program, to focus on more open 
systems and modular systems so that the solution--the first 
solution may not be the perfect solution. It is capability to 
bring to bear, and then evolve it and grow it over time--what I 
would call more of an agile approach to bringing capability to 
bear. I think that is really important.
    I think some of the delays in, like, the interceptor 
production lines and the munitions production lines, one, I 
think there are improvements we could make to stabilize the 
funding and the demand signal on the munitions line. I bought 
munitions for the Air Force, I buy munitions now, and the yank 
up and yank back, invest to expand lines, then don't fund 
production on those lines--I think a stabilization of that 
could actually help us to increase the cadence and the 
availability of the needed weapons that we require going 
forward. I think that is probably a very key item where we 
could look at.
    And, potentially, even how we procure munitions. We procure 
munitions with a lot of the same rule sets that we do as from 
larger weapon systems. There may be a more agile way to get 
after how we buy the parts and set up the production lines to 
support more agile weapons development and delivery.
    Mr. Whitesides. Thank you so much.
    Ms. Yaffe, last question. I have about a minute here. I am 
the new guy here, so what I don't really get is--you know, we 
were doing missile defense before, and now we have this Golden 
Dome thing. What were we not working on before that we now are 
working on? Or is Golden Dome sort of like a rebranding of what 
we had before under a new executive order? Like, is there some 
requirement that we didn't do before that we now have?
    And we have about 45 seconds.
    Ms. Yaffe. Sir, thank you for the question.
    The basic answer is that, until now, missile defense has 
been focused on rogue-state intercontinental ballistic missile 
threats, so essentially North Korea. The direction in the 
Golden Dome executive order is to focus on the whole range of 
missile threats--the ballistic, hypersonic, cruise missile, 
advanced aerial threats--from all nations. And that is a 
significant shift in both policy and direction.
    Mr. Whitesides. So we were doing that before, but you are 
talking about, like, maybe numbers? Like, we are now going to 
be able to intercept hundreds or thousands of things that are 
heading towards us or something?
    Ms. Yaffe. Sir, I can't comment on what the architecture 
will be and the kinds of numbers it will be set up against. 
But, ultimately, the homeland missile defense was focused on 
leveraging the ground-based interception interceptors for the 
North Korea threat, which was, of course, much smaller in 
number.
    Mr. Whitesides. Thanks.
    I yield back.
    Dr. DesJarlais. The gentleman yields back.
    The chair now recognizes the gentleman from Indiana, Mr. 
Messmer, for 5 minutes.
    Mr. Messmer. Thank you, Chairman.
    General Collins, thank you for our conversation earlier 
today.
    Your predecessor testified that the Glide Phase Interceptor 
program schedule, which is anticipated in 2032, roughly, in his 
words, didn't meet the threat. Is the Missile Defense Agency 
developing options to accelerate the program?
    General Collins. Congressman, thank you. And thank you for 
your time this morning.
    Hypersonic missile defense is a key area that does need 
additional focus. The Glide Phase Interceptor program was--due 
to priorities and resourcing decisions last year, we were 
driven to make an earlier selection and to down-select years 
earlier than planned. That has actually delayed the program, 
and the funding line and profile that we have in the budget 
that you all received last year will actually push that 
delivery to 2035.
    We are pursuing and evaluating acceleration options. It is 
primarily a resourcing at this point. There are some technology 
things that need to happen in the next 3 to 5 years, but then 
there is a resourcing and alignment issue that could accelerate 
that.
    We believe we could recover to 2032 with no increased level 
of programmatic risk across the program. But that is about the 
fastest we could do today.
    We are looking and exploring other alternatives and options 
to potentially bring residual capability or partial capability 
from other weapons systems we have. But, as it stands today, 
the only hypersonic maneuvering target defense capability we 
have is in the fleet with the Standard Missile-6 and the sea-
based terminal capability.
    Mr. Messmer. Okay. Thank you.
    What is the status of the Next-Generation Interceptors?
    General Collins. Yes, sir. The Next-Gen Interceptor, as 
briefed last year as well, due to a funding decision and 
priorities, we did down-select to a single contractor last 
year, a year and a half earlier than expected.
    So that program still continues on and is our largest and 
highest-priority program for homeland defense.
    We have made significant progress at the system level. The 
next generation interceptor is the booster, the interceptor, 
but the broader weapon system is also now fully aligned and 
synchronized with the next generation interceptor program, 
which is a major feat for the enterprise.
    Last year, I briefed that our number-one issue and risk 
going forward with either of the vendors at that time was the 
solid rocket motor effort and development. This is a new 
booster, a new development, and we have experienced delays and 
issues with that development and are expecting an 18-month-or-
more delay into the delivery of that initial capability.
    We have taken actions to shore up that development as well 
as bring in an additional source to help buy down the schedule 
risk of the development as we move forward.
    It still is the foundation for the future of 
intercontinental ballistic missile protection of the homeland, 
and we are 100 percent committed and focused on that program.
    Mr. Messmer. Okay. Thank you.
    What do you see as the space-based interceptor's role in a 
layered defense to ballistic and hypersonic threats?
    General Collins. Thanks, Congressman.
    We are certainly taking a close look. The executive order 
has opened that up for us to take a closer look and move 
forward on developing that. We will work through the technology 
piece to better understand and move that as quickly as 
possible.
    If anything that we have learned over the last year, 2 
years, in Israel, eastern Med, and Ukraine is that a layered 
missile defense approach and design is paramount to the large 
rate sizes that we expect, that we have seen last year and that 
we would expect in the future. And adding another layer, a 
space-based intercept layer, to that certainly looks to 
increase the performance of the overall architecture.
    Mr. Messmer. Okay. Thank you.
    As a follow-up to that, General Guillot, you have 
previously stated support for a layered missile defense 
approach with a space component. Could you go into more detail 
on how that would fit into Northern Command's perspective from 
a defense standpoint?
    General Guillot. Congressman, having a layered approach, 
from the North American Aerospace Defense Command and Northern 
Command perspective, is essential to make sure that we can 
identify, track, and guide on all threats.
    Mr. Messmer. Okay. Thank you.
    General Collins, as you know, Iron Beam is an Israeli-
developed directed-energy defense system designed to defend 
against short-range rockets, drones, artillery, and mortar 
bombs. Can you discuss where things stand with our Iron Beam 
procurement and any funds set aside for this?
    General Collins. Yes, Congressman.
    On the U.S. side, there are no funds at this point set 
aside for Iron Beam.
    As part of the Israeli supplemental from last year, there 
is a portion of that that we are working with our Israeli 
Missile Defense Organization partners to execute and bring that 
money to them to continue the development and fielding of Iron 
Beam.
    One thing that we have negotiated in that agreement, 
though, was that 50 percent of that investment is a payback 
into the U.S. economy. So, while it goes to Israel, they have 
to have half of the contracts--half of the money comes back 
into building our industry base. And so that supplemental 
actually will serve to increase the industry base skill set and 
capability that will pay back into our directed-energy efforts 
as we move forward.
    Mr. Messmer. Okay. Thank you.
    I yield back my time.
    Dr. DesJarlais. The gentleman yields back.
    The chair now recognizes the gentleman from California, Mr. 
Carbajal.
    Mr. Carbajal. Thank you, Mr. Chairman.
    And thank you to all the witnesses for being here today.
    We hear a lot about Golden Dome, but there doesn't really 
seem to be a whole lot of clarity on what the point is. You 
know, it reminds me of that commercial, that Wendy's 
commercial, ``Where's the beef?''
    And so it seems that, you know, a concept has been thought 
of, which has been thought of before in the past, and it seems 
that we are going about it in a way-backwards way to field the 
system eventually.
    Generals Guillot, Collins, and Gainey, how is the concept 
of Golden Dome different than our current missile defense 
architecture? And did any plans exist to develop space-based 
capabilities for both missile tracking and missile interception 
prior to January 2025?
    General Guillot. Congressman, I think the big difference 
that you will see is, Golden Dome takes all of the existing 
requirements that we had but, for the first time, integrates 
multiple layers into one system that allows us to detect, 
track, and defeat multiple types of threats that affect us in 
different domains with one system.
    So, while a lot of the components and the requirements were 
there in the past, this is the first time that it is all tied 
together in one system.
    And, yes, there were certainly space-based ability to 
detect and track prior to this.
    General Collins. Congressman, to build on General Guillot's 
response, the architecture plan that Missile Defense Agency had 
before January of 2025 included a space layer for hypersonics 
and ballistic missile tracking and discrimination as we move 
forward, and most of the other components and pieces/parts of 
what the executive order included were part of the architecture 
plan that we were going to get after.
    I think maybe the biggest impact of this activity is, it 
will accelerate many of those options. Quicker resources. The 
schedule is pretty long to get to some of these activities.
    The space-based interceptor piece was not in the 
architecture plan before January 2025.
    Mr. Carbajal. Great.
    General Gainey. And, Congressman, the only point I will add 
that wasn't covered by General Guillot and General Collins is, 
the executive order also called out left-of-launch missile 
defeat.
    I think that is an important aspect of missile defense that 
has been neglected to date. And focusing capabilities and 
efforts towards the attriting of a missile force prior to 
launch is an important aspect of the holistic missile defeat 
program.
    Thank you.
    Mr. Carbajal. Thank you.
    General Collins, can you give us an update on the 
Hypersonic and Ballistic Tracking Space Sensor, HBTSS, program 
and what we have learned from the prototype demonstrations? 
What is the current plan to develop an operational 
constellation beyond the prototype stage?
    And how do adversaries' growing counter-space capabilities 
influence the Missile Defense Agency's view of the appropriate 
mix of space-based and ground-based sensors in missile defense?
    General Collins. Thank you, Congressman.
    So, first off, Hypersonic and Ballistic Tracking Space 
Sensor, it was launched in February last year, on Valentine's 
Day. We quickly had our first hypersonic testbed test in June, 
and then we had one later in the year, and both of those were 
very successful.
    The three main objectives of the Hypersonic and Ballistic 
Tracking Space Sensor prototyping were to show that we could 
have the appropriate sensitivity in orbit to see a hypersonic 
vehicle throughout its entire flight; to be able to have the 
quality of service, the accuracy of a track to be able to close 
a fire control loop; and for that data to come down and enter 
the command and control system fast enough, so latency.
    And we have had two hypersonic testbed flights. As well, 
coincident with another flight test that we did just a month 
and a half ago taking a look at Standard Missile-6, we also had 
Hypersonic and Ballistic Tracking Space Sensor in view, and it 
tracked that new hypersonic target that was used in that test 
very well. And so we have proved out the capability to get 
after the accuracy, get after the latency. We are tweaking the 
algorithms to improve our quality of service, but we see it as 
a very successful demonstration of that capability.
    We have been partnered with the Space Development Agency 
all along. They have been tracking and were part of our 
Hypersonic and Ballistic Tracking Space Sensor development. And 
they have our requirements and plan to integrate that 
capability, that level of requirement and tech, into the 
Proliferated Warfighter Space Architecture and build that up 
over the coming tranches to give us eventually a global 
capability to track hypersonic weapons.
    Your last question, sir, was?
    Mr. Carbajal. I am out of time.
    Dr. DesJarlais. The gentleman's time--
    Mr. Carbajal. If you could answer that for the record, that 
would be great, afterwards.
    General Collins. Will do, Congressman. Thank you.
    [The information referred to can be found in the Appendix 
on page 113.]
    Dr. DesJarlais. Thank you.
    The chair now recognizes the distinguished gentleman from 
South Carolina, Mr. Wilson.
    Mr. Wilson. And thank you very much, Dr. Chairman 
DesJarlais.
    And we appreciate all of your service. And what an 
important time in history, what a great opportunity, I believe, 
we have in history to protect the American people. And we thank 
you all for being here today.
    And, sadly to me, we are in a conflict we didn't choose, 
and that is, dictators with the rule of gun invading 
democracies with the rule of law. It began February 24, 2023, 
the invasion by war criminal Putin of Ukraine; October 7, the 
invasion, I consider, of Israel by Iran, its puppets. And so we 
have just got to be prepared.
    And we know that, earlier this month, Russia launched over 
70 missiles to the capital of Kyiv against civilian targets 
that had catastrophic effect on--35 people killed on a bus. 
Over and over again, just war crimes that should never occur.
    And then Tehran has directly fired missiles, itself, 
directly from Iran and with its puppets, against civilian 
targets in Israel.
    And then we have the Chinese Communist Party continuing to 
expand their arsenal of medium- and intermediate-range 
ballistic missiles, posing a significant threat to the United 
States and our allies across the Pacific.
    And it is my view that we must be prepared to strengthen 
our capabilities to deter the adversaries so that we can 
establish peace through strength.
    And, General Gainey, as we modernize to deter and defend 
ourselves against the adversaries with increasingly deadly 
capabilities, we are moving towards setting up a revolutionary 
new missile defense system, the Golden Dome, which has been so 
advocated and appreciated by President Donald Trump.
    With that in mind, General Gainey, as the service 
representative on the panel with the, quote, ``organize, train, 
and equip'' responsibilities, are you providing input on the 
personnel and training requirements that would be associated 
with the options under consideration for Golden Dome?
    General Gainey. Congressman, thank you for that question.
    I have not been part of the architecture work to date, so, 
therefore, I have not had any input on the organizational/
training aspect of it.
    But what I can say is, I have significant input into the 
Army's organization, modernization, and way forward, and any 
elements of the Army that may be part of that architecture will 
have already been vetted.
    And as the potential operational component for Northern 
Command doing the Ground-Based Midcourse Defense system, as we 
ingest additional technology into the architecture, my team 
will be prepared to advise Northern Command and assist as 
necessary.
    Mr. Wilson. Well, we certainly have faith in you and your 
colleagues.
    With that in mind, too, General Gainey, with war criminal 
Putin's unprovoked invasion, which is to actually reestablish 
the failed Soviet Union, we see the axis of evil of the Chinese 
Communist Party, war criminal Putin, Democratic People's 
Republic of Korea, North Korea, and the regime in Tehran 
continue to build up their missile capabilities, with the 
threat against the United States and our allies continuing to 
grow.
    And, General, what is the Army's position on foreign 
military sales for the Lower Tier Air and Missile Defense 
Sensor? Does the Army support partner nations' purchasing the 
system as a standalone item?
    General Gainey. Again, Congressman, thanks for your 
question.
    The Lower Tier Air and Missile Defense Sensor radar is an 
exportable system currently, and it is currently part of our 
foreign military sales system. And Poland has purchased the 
system already.
    And, yes, it is available as a standalone option. However, 
we continue to encourage it to be purchased as part of the 
Integrated Battle Command System, because that promotes the 
interoperability between our allies and the U.S. as we move 
forward.
    Mr. Wilson. And that is exciting. It is so exciting to see 
Poland come to life and be free.
    And, Secretary Yaffe, I am very concerned about the 
weaponization of space by war criminal Putin and the Chinese 
Communist Party and with the potentiality of overriding or 
evading the ground- and sea-based missile defense systems.
    How can this be addressed, the weaponization of space?
    Ms. Yaffe. Sir, thank you for the question.
    I think we are tracking China and Russia's developments in 
space very closely. They have both put up a number of 
capabilities of concern designed to hold our critical space-
based assets at risk, and that is part of the discussion.
    At the same time, we hope to leverage space to enable our 
sensors to be most effective in the future Golden Dome system.
    Mr. Wilson. Well, thank you again for your service.
    I yield back.
    Dr. DesJarlais. The gentleman yields.
    The chair now recognizes the gentleman from Wisconsin, Mr. 
Van Orden.
    Mr. Van Orden. Thank you, Mr. Chairman.
    I just want to clear up a couple things here.
    This is the ``Missile Defense and Missile Defeat 
Programmatic Updates'' hearing. So we are here to talk about 
these, right? I took the liberty of having my crack graphics 
team draw up some of these. So we are here to talk about this 
stuff, right?
    So, if this happens and we don't stop it, this is going to 
happen, right? Mushroom cloud. No more America.
    So we are not here to talk about these, correct?
    Okay. I am a retired Navy SEAL senior chief. We know how to 
take care of boats.
    All right. I just wanted to clear that up.
    General Guillot, when was the Iron Dome first developed?
    General Guillot. Congressman, I am not exactly sure, but it 
has been a couple decades.
    Mr. Van Orden. Okay. Has it been improving, would you say?
    General Guillot. The Iron Dome, the--
    Mr. Van Orden. Yeah.
    General Guillot. --Israeli system?
    Mr. Van Orden. Yes.
    General Guillot. Yes, it has been improving.
    Mr. Van Orden. Okay.
    So they started without a missile defense system, and then 
they had an idea, and then they started building on it, and 
then they got to initial operational capability, and now they 
are continuing to improve it.
    So could we logically say, like, we could extend our--do a 
thought experiment here, like, an Einstein thought experiment? 
Could we say that we, as the United States of America, who has 
been intimately involved in the development of the Iron Dome 
system, could we say that maybe we could apply that here in the 
United States and that it will work?
    General Guillot. Sir, we have been involved with the 
development of the Iron Dome. I think General Collins could 
attest to that.
    Mr. Van Orden. Uh-huh.
    General Guillot. The--well, first, I want to confirm.
    General Collins. Yes, sir. So we have been partnered with 
Israel Missile Defense for two decades. And we actually were 
not part of the development of Iron Dome. We helped co-produce 
that. But we have--their upper tiers, David's Sling and Arrow--
    Mr. Van Orden. Yeah.
    General Collins. --we have co-developed with them. And so 
we have helped partner, design their architecture and are 
intimately integrated. Our system and their system are 
integrated together to work, yes, sir.
    Mr. Van Orden. Okay. So we could say that there is a 
functioning of a pretty darn--General Bacon pointed out, you 
know, 99 percent of these things. That is functioning in Israel 
right now.
    We have a larger industrial base than Israel. We have a 
greater Gross Domestic Product than Israel. And we have a 
larger population than Israel.
    So can we say that if we applied the same type of thought 
process, the development of Iron Dome, and we put it here in 
the United States and we called it, like, Golden Dome or 
something, could we reasonably assume that that will function 
at some point in the future to protect the United States of 
America against these threats?
    General Collins. Yes, sir.
    Mr. Van Orden. Okay. Well, I am glad we cleared that up.
    Now, listen, I am not of the mind that we should be shaping 
our defense policy on whether or not it is going to provoke 
Russia. I think that is a straw-man argument and I think that 
it is a politically derived argument that potentially puts the 
United States of America in jeopardy.
    So what we need to do is make sure that we robustly--and I 
trust you guys to do this. How long have you been doing this 
job?
    General Guillot?
    General Guillot. I have been the Commander since--
    Mr. Van Orden. No, I mean, like, the Air Force--
    General Guillot. Oh. Thirty-six years, sir.
    Mr. Van Orden. Thirty-six years.
    General Collins, how long have you been doing this?
    General Collins. Thirty-two.
    Mr. Van Orden. General Gainey?
    General Gainey. Thirty-four.
    Mr. Van Orden. Ma'am, they have all been doing the job 
longer than you have been alive. I am just saying. How long 
have you been in this--in the defense position like this?
    Ms. Yaffe. In this position, for a few months. I have been 
in the Office of the Secretary of Defense for 15 years.
    Mr. Van Orden. Okay.
    So we have got, what, 100-and-some years of whatever 
experience, like, dealing with defense policy and anti-missile 
machinery, equipment, policy, deployment, right?
    Okay. That means that you guys are a tableful of subject-
matter experts. And because we sit behind this dais with a 
microphone doesn't make us experts in these types of fields. 
And so I would just want to make sure that we are leaning 
heavily on the experts and understand that you have done this 
before, we are using integrated anti-missile defense systems in 
Israel, and that they can work.
    And this is the last thing before my time expires. I 
represent Volk Field and also Fort McCoy. I am giving you an 
open invitation to--when this Golden Dome gets done, I would 
like a battery of whatever it is going to look like at Volt 
Field or Fort McCoy in the State of Wisconsin to help protect 
the Upper Midwest.
    That is an open invitation. If you guys haven't been there, 
I want to invite you. I will give you some cheese curds. But I 
want your soldiers and airmen and Space Force people or 
whatever they--Guardians--at some point in my district to help 
protect the United States of America.
    So thank you very much.
    And, with that, I yield back.
    Dr. DesJarlais. The gentleman yields back.
    The chair now recognizes the gentleman from Colorado, Mr. 
Crank.
    Mr. Crank. Thank you, Mr. Chairman.
    Thank you to our witnesses.
    You know--and it is interesting, as I am listening to this 
discussion, I had a colleague come to me not long ago after I 
was talking about Golden Dome and my support for it, and that 
colleague said to me, essentially, you know, ``That is a pipe 
dream. It is just never going to work.''
    And I got to thinking about it, because I have maybe a bit 
of a unique perspective. I worked as a staff member on Capitol 
Hill 30 years ago. I look across these pictures, and Les Aspin 
was chairman, Ron Dellums, Mr. Spence. And I remember Mr. 
Dellums, specifically, was an outspoken opponent of ballistic 
missile defense. This was in the 1990s, and we had arguments on 
the House floor about how this would never work, missile 
defense would never work. Argued against the Terminal High 
Altitude Area Defense program. ``It will never work,'' they 
said.
    And, you know, today, as I was talking to that colleague, I 
would ask, ``Well, maybe we should ask the Israelis if it would 
work.''
    And I guess I would ask you this. We have these arguments 
about whether we--if this is a technical problem or whether 
this is a problem of political will. And America does great 
things, but every great thing we have ever done has been 
difficult. There were people at the time who said we couldn't 
land a man on the Moon, and we did it, but there were naysayers 
back then who said, ``We can't do this.''
    I would ask, General Guillot, your thoughts. Is this a 
technical issue, or is it a political-will issue? Can we do 
this technically?
    General Guillot. Yes, Congressman. There are certainly 
technical challenges with the integration of all these 
capabilities into one, but it is certainly possible.
    Mr. Crank. Yeah.
    General Collins, your thoughts?
    General Collins. Sir, we have demonstrated over the last 2 
years that these systems can work, the ground-based systems 
that we have today.
    We have some understanding to do, to General Guillot's 
point--the technical integration to bring a space-based 
interceptor to work, the understanding of what a lifecycle cost 
of maintaining a constellation is and what that brings to the 
fight. All those things need to be worked through as we move 
forward.
    But we certainly believe in layered missile defense. And we 
have shown throughout the last 2 years that those systems work 
and bring capability and they save lives.
    Mr. Crank. Yeah.
    General Gainey?
    General Gainey. Thank you, Congressman.
    Yeah, I agree. And in a previous job where I worked 
counter-unmanned-aerial-system technology, pushing the envelope 
on technology, whether it is directed energy, non-kinetic--it 
is amazing what industry can come up. Yes, there are 
challenges, but there are always opportunities.
    Mr. Crank. Yeah. It seems to me that there are some people 
on Capitol Hill who are just so invested in mutually assured 
destruction that we can't shift our paradigm a little bit.
    And we better hope, if that is what we are going to rely 
on, is mutually assured destruction, is that our adversaries 
don't figure out a way to have ballistic missile defense, that 
they don't figure out a Golden Dome. Because then mutually 
assured destruction will be a thing of the past, and we will be 
left in the dust on that. So I think that is very important.
    With the remaining time I have, General Collins, the 
Missile Defense Agency has been a strong advocate for the 
importance of space-based sensors that collect fire control 
quality data. Can you talk about why that level of fidelity is 
so important to missile defense operations?
    General Collins. Yes. Thanks for that, Congressman.
    Certainly, we do see a future--as I mentioned, our 
architecture did include a number of different sensing 
capabilities in space, one being the Hypersonic and Ballistic 
Tracking Space Sensor to look down and pick up the maneuvering 
targets and hold them under custody through the entire time of 
flight.
    Closing the fire control loop, is what we call it--fire 
control, the kill chain for missile defense. To get our 
interceptor to work, we need to get it into the right location 
and looking in the right space to find the missile when it 
comes time to intercept. And without the appropriate level of 
sensitivity, track quality, and timeliness, we do not get that 
information to the interceptor in time, and, therefore, we 
cannot consummate the intercept and we will miss.
    And so that is going to be very important. Whether that is 
a hypersonic interceptor, whether that is a ballistic missile 
that we intercept in boost phase, midcourse phase, or terminal 
phase, we need to get that cue really tied in and to the 
interceptor--to the command and control system and into the 
interceptor as quickly as possible to be able to close that 
chain and actually do the intercept.
    Mr. Crank. Yeah. Thank you, General. I appreciate that.
    I would just say, Mr. Chairman, I mean, these are hard 
discussions, but we sit in this committee room and we hear 
about the threat from China day-in and day-out, we hear about 
the threat from Russia day-in and day-out, and then we sit up 
here from this dais or out on the House floor and we make 
excuses about why we can't fund these things.
    I would yield back. Thank you.
    Dr. DesJarlais. I thank the gentleman.
    And I would like to thank all of our witnesses on behalf of 
Ranking Member Moulton and all the committee members for your 
thoughtful testimony.
    That will conclude the open portion of this hearing. We 
will now move into the closed session upstairs.
    [Whereupon, at 4:10 p.m., the subcommittee proceeded in 
closed session.]

            RESPONSE TO QUESTIONS SUBMITTED BY MR. CARBAJAL

    General Collins. MDA is fully considering adversarial 
counter-space capabilities, which is why MDA has advocated for 
dual-phenomenology, birth-to-death tracking of missile threats. 
Space-based and ground-based sensors are both necessary, with 
each focused on the areas that provide the best performance. 
Spaced-based sensors are ideally suited for visible/infrared 
passive sensing that requires limited power, whereas satellite 
solutions can economically provide worldwide coverage (Space 
Based Infrared Systems, PWSA, DSS, etc.) Ground-based sensors 
are ideally suited for power-intensive active radar systems 
that can provide all-weather capability along expected threat 
corridors (LRDR, UEWR, AN/TPY-2, etc.).
    MDA will defer to the U.S. Space Force on resilience 
methods and techniques planned for critical space-based 
sensors. The Missile Defense System is designed to gracefully 
degrade with the loss of space-based capabilities. For example, 
the ground-based radars can use space-based tracking data as a 
cuing source to increase raid capacity, but they can implement 
autonomous surveillance fences if the space-based tracking data 
is unavailable. Similarly, while the Missile Defense System 
benefits from having both space-based and ground-based tracking 
data, the system can engage threats if tracking data from only 
one source is available.  [See page 20.]

             RESPONSE TO QUESTIONS SUBMITTED BY MR. WILSON

    Mr. Wilson. The next generation missile defense shield cannot be 
approached with the same old thinking and practices that have governed 
legacy systems.
    Can you tell me about novel approaches, concepts, or authorities 
being evaluated for missile defense?
    General Collins. The peer/near-peer threat continues to proliferate 
in capacity and complexity, expanding a robust strike capability 
designed to outmatch our defenses. To combat this trend, MDA is using 
rapid prototypes with short sprints to develop and demonstrate 
disruptive, game- changing asymmetric capabilities, with incremental 
capability off-ramps to the warfighter.
    MDA is evolving the Next Gen system attributes to include: agility; 
flexibility; multi-domain operability; continuous birth-death tracking; 
low cost per defeat; distributed, intelligent command, control, battle 
management, and communications; resilience; compatibility of any sensor 
with any effector; success despite discrimination; space-enabled 
communications; kinetic and non-kinetic missile defeat; and integration 
of the timeline's left and right of launch.
    MDA is accelerating the acquisition timelines, leveraging its 
unique acquisition authorities. MDA is leveraging a variety of 
authorities and acquisition approaches, including traditional and non-
traditional partners, including Other Transaction Authority, Multiple 
Announcement Authority, Commercial Solutions Openings, Broad Agency 
Announcements, Procurement for Experimental Purposes, Pilot Program to 
Incentivize Contracting with Employee-Owned Businesses, and Pitch Days.
    Additionally, MDA is transitioning to a digital engineering model 
that will expedite the evaluation, requirements, testing, and 
qualification processes, resulting in faster capability delivery. The 
approach includes an advanced modeling, simulation, and analysis 
laboratory that provides element/component-level performance assessment 
up to mission-level analysis at all classifications. The lab is on a 
growth path, repeating the models across the DoD enterprise, providing 
an integrated approach to missile defeat. The capabilities will 
integrate into the National Integrated Air & Missile Defense Center 
(NIC) and provide an initial capability in 2026.
    Mr. Wilson. General Gainey, there are 15 US Patriot Air Defense 
Battalions in the Army, with plans to grow to 16 battalions soon. These 
Air Defense Artillery (ADA) forces are currently forward-deployed 
supporting combat operations throughout the CENTCOM area of 
responsibility, and forward-stationed in EUCOM and INDOPACOM for Army 
Integrated Air and Missile Defense contingency operations.
    Last month two additional Patriot batteries were reportedly 
deployed overseas in support of Israel. Do you believe that we need to 
increase the Patriot force structure?
    General Gainey. Yes. ARSTRUC has approved additional Patriot 
battalions and the Guam composite battalion, therefore increased force 
structure is already moving forward.
                                 ______
                                 
             RESPONSE TO QUESTIONS SUBMITTED BY MR. TURNER
    Mr. Turner. Directed energy systems, including high-energy lasers 
and high-power microwaves, have been touted as potential game-changers 
for missile defense due to their speed-of-light engagement and deep 
magazines. Can you provide an update on the Department's progress in 
developing and fielding directed energy systems for missile defeat 
roles? Specifically, what are the current technical and operational 
challenges, what timelines are realistic for operational deployment, 
and how is the Department ensuring these systems are integrated into 
existing and future layered missile defense architectures? Missile 
Defense Agency has explored directed energy concepts for several years 
as a potential cost-effective layer in the missile defense 
architecture. Can you provide the Committee with an update on MDA's 
current investments and progress in directed energy for missile defeat, 
particularly for boost-phase and cruise missile defense? What are the 
key technical hurdles still facing these programs, and how is MDA 
coordinating with the services and industry to ensure directed energy 
is integrated into the broader missile defense system of systems?
    General Collins. The Missile Defense Agency (MDA) is prioritizing 
the integration of directed energy systems into the Missile Defense 
System, significantly reducing the burden on kinetic interceptors and 
augmenting the way we fight.
    High-energy laser (HEL) technology has matured and is on a path to 
demonstrate the initial airborne capability at lower HEL power levels. 
While the HEL effort will have technical integration challenges to 
resolve, funding is the greatest challenge to delivering a directed-
energy weapon. The plan includes a series of two-year sprints of 
increasing power, with a demonstration and potential off-ramp of 
operational capability to service partners as early as 2027. As the 
power levels increase, the HEL will progressively provide capability 
against more challenging aerial and missile threats on the path to an 
objective capability.
    In 2024, MDA initiated work on a phased, airborne long-range 
detect-and-track HEL rapid prototype, coupled with a kill laser. The 
HEL could thin the herd, lower the cost per kill, and provide a nearly 
unlimited magazine, with mission sets including unmanned aerial 
vehicles, cruise missiles, ballistic missiles, and hypersonic threats. 
MDA is on a path to demonstrate progressively higher HEL power levels, 
with incremental capability off-ramps to Service partners on the path 
to an objective capability. The Office of the Under Secretary of 
Defense for Research and Engineering (OUSD(R&E)) High Energy Laser 
Scaling Initiative has demonstrated HEL power levels in the kilowatt+ 
range, on a path to megawatt+.
    MDA is supporting a joint OUSD(R&E) Probability of Weapons 
Effectiveness Experiment (PWEX) effort to determine the effectiveness 
of HEL weapon systems against a series of dynamic targets. In 2024-
2025, PWEX successfully engaged and negated a series of dynamic targets 
in crossing and head-on profiles. The High Energy Laser for Regional 
Airborne Defense effort is exploring the application space for state-
of-the-art directed-energy systems as they apply to future MDA 
architectures, identifying opportunities for Diode Pumped Alkali Laser 
and fiber lasers in MDA's future directed-energy programs.
    Mr. Turner. One of the critical enablers of effective missile 
defense, particularly against advanced threats like hypersonic glide 
vehicles and maneuverable reentry vehicles, is persistent global 
tracking. Space-based sensors are essential to closing that gap. Can 
you describe how the Department is integrating space-based sensor 
programs-such as the Hypersonic and Ballistic Tracking Space Sensor 
(HBTSS) and the broader Proliferated Warfighter Space Architecture-into 
the missile defense enterprise? Who has lead responsibility for this 
integration, and how are MDA, Space Force, and SDA coordinating to 
ensure seamless tracking, data fusion, and operational responsiveness?
    General Collins. The Missile Defense Agency (MDA) agrees space-
based sensors are essential for persistent global tracking. The Missile 
Warning/Missile Tracking/Missile Defense Combined Program Office, 
jointly staffed by MDA and the U.S. Space Force's Space Development 
Agency (SDA) and Space Systems Command), integrates Hypersonic and 
Ballistic Tracking Space Sensors (HBTSS), Proliferated Warfighter Space 
Architecture (PWSA), and Medium-Earth Orbit Track Custody (MTC) sensors 
into the Ballistic Missile Defense System Overhead Persistent Infrared 
Architecture (BOA) and Command and Control Battle Management and 
Communication (C2BMC), to deliver fire-control data to the Missile 
Defense Enterprise.
    MDA is closely coordinating with the SDA and U.S. Space Force to 
deliver persistent global tracking and discrimination of multiple 
threat types from space. In 2024, MDA delivered two prototypes of the 
HBTSS on orbit. These prototypes will inform SDA plans for the PWSA, 
which will provide fire-control quality tracks on hypersonic threats 
and boosting ballistic missiles. Integration of track data from all 
current and future space sensor assets will be done by BOA, who will 
send the collected data as a single source set to C2BMC as the system-
of-systems integrator for integration with ground sensors. Following 
what has been an extremely successful HBTSS program, MDA plans to 
deliver future space sensor demonstrations such as Discriminating Space 
Sensor (DSS). Like HBTSS, fielding of a DSS capability will be 
accomplished by SDA as part of the PWSA.
    Although space-based sensors are essential in closing the gap on 
persistent global tracking and discrimination; we cannot rely solely on 
space. For resilient, robust sensing of incoming missiles, both 
terrestrial and space-based sensing are required, using complementary 
sensor types. To that end, MDA is also collaborating with the USSF and 
U.S. Air Force to expand and improve terrestrial sensing.
    The MDA's C2BMC program office is leveraging its many years of 
experience incorporating data from OPIR sensors into the BOA, to inform 
how new data is integrated into the Missile Defense Enterprise. Data 
from new sensors such as HBTSS and the PWSA tracking satellites and the 
MTC satellites will be integrated through BOA and C2BMC. These systems 
ensure seamless tracking, data fusion, and responsiveness is maintained 
to support the Missile Defense mission.
    Through prototype and experimentation efforts, BOA has already 
demonstrated successful fusion of HBTSS data as PWSA Tranche 0 Tracking 
Layer data. Additional details regarding coordination and integration 
will be forthcoming from the Department of Defense following approval 
of the Golden Dome for America architecture.
    Mr. Turner. One of the critical enablers of effective missile 
defense, particularly against advanced threats like hypersonic glide 
vehicles and maneuverable reentry vehicles, is persistent global 
tracking. Space-based sensors are essential to closing that gap. Can 
you describe how the Department is integrating space-based sensor 
programs-such as the Hypersonic and Ballistic Tracking Space Sensor 
(HBTSS) and the broader Proliferated Warfighter Space Architecture-into 
the missile defense enterprise? Who has lead responsibility for this 
integration, and how are MDA, Space Force, and SDA coordinating to 
ensure seamless tracking, data fusion, and operational responsiveness?
    General Gainey. Defer to MDA.
    Mr. Turner. The Department of Defense Directive 5134.20E, which 
became effective on April 25, 2025, updated key responsibilities and 
authorities related to the Missile Defense Agency and its acquisition 
framework. Can you outline for the Committee the most significant 
changes in this updated directive and explain how they are expected to 
impact the development and fielding of missile defense capabilities? 
Additionally, while this directive was approved under Secretary Austin, 
can you speak to whether Secretary Hegseth intends to continue this 
policy as written, or if there are any changes directed-particularly 
those that may affect how missile defense systems are acquired, 
integrated, or managed across the Department?
    Ms. Yaffe. The Department recently issued two DoD Directives 
regarding the Missile Defense Agency (MDA):
    The MDA Charter, DoD Directive 5134.09, "Missile Defense Agency," 
April 25, 2025, which updates the mission, organization and management, 
administration, responsibilities and functions, relationships, and 
authorities of MDA; and
    DoD Directive 5134.20E, "Missile Defense System Acquisition 
Policy," April 25, 2025, which establishes policy, assigns 
responsibilities, and prescribes procedures for the acquisition of 
missile defense system elements. These directives incorporate changes 
designed to maintain agility while reducing program risk. Significant 
changes include:
    Establishes Milestone Decision Authority for Missile Defense System 
(MDS) elements as follows:
    The MDA Director is the Milestone Decision Authority for all 
Milestone decisions except for hardware-intensive programs that either 
exceed the RDT&E dollar threshold for an acquisition category (ACAT) I, 
or are designated as a special interest program. For MDS elements in 
those categories, the Milestone Decision Authority is the MDA Director 
for the Technology Development Decision (TDD or Milestone A), and the 
Under Secretary of Defense for Acquisition and Sustainment (USD(A&S)) 
for the Product Development Decision (PDD or Milestone B) and the 
Production Decision (PD or Milestone C).
    For Hardware intensive elements that exceed the RDT&E dollar 
threshold for ACAT I programs or that are designated as special 
interest, the USD(A&S) is the Milestone Decision Authority for Product 
Development Decisions (PDD or Milestone B) and Production Decisions (PD 
or Milestone C). USD(A&S) may delegate this authority.
    Designates the MDA Director as the Executive Agent for Hypersonic 
Defense and states that the MDA Director will serve as the DoD 
technical authority for integrated air and missile defense activities 
and programs.
    Updates the Ballistic Missile Defense System to the MDS to reflect 
inclusion of hypersonic missile defense along with the ballistic 
missile defense mission.
    Incorporates Independent Cost Estimates, Independent Technical Risk 
Assessments, and Capability Utility Assessments at Product Development 
and Production decisions. These may be delegated and, in some cases, 
waived.
    All changes were coordinated in accordance with 10 USC 5502. The 
Department has certified in writing that these changes will not impair 
the missile defense capabilities of the United States.
    The Department is following this policy as written. Additional 
changes may be needed in the future to develop and deploy advanced 
missile defense capabilities at the necessary speed to achieve the 
President's plan for Golden Dome for America.
                                 ______
                                 
              RESPONSE TO QUESTIONS SUBMITTED BY MR. BACON
    Mr. Bacon. As the NORAD commander, one of the primary capabilities 
that you rely on is the tactical air forces from the US Air Force and 
Air National Guard. These forces are generated from our alert units and 
their support, fighter aircraft, airborne command and control, and 
tankers. Can you provide the committee details on your minimum force 
requirements to accomplish your Aerospace Control Alert or ACA mission 
for homeland defense?
    General Guillot. Aerospace Control Alert (ACA) - 1 represents the 
minimum force requirements to accomplish the steady-state NORAD 
mission. A change in the geopolitical environment or adversary activity 
could lead to a requirement for an elevated NORAD response (ACA-2 or 
higher).
    I am also providing a more detailed classified response, as the 
resources associated with each of the NORAD response postures is held 
at a higher classification.
                                 ______
                                 
              RESPONSE TO QUESTIONS SUBMITTED BY MR. BELL
    Mr. Bell. How have NORTHCOM and MDA participated in the development 
of Golden Dome for America architecture?
    General Collins. MDA provided recommendations, analysis, and input 
as requested by Office of the Secretary of Defense in support of the 
development of the Golden Dome for America architecture. General 
Michael Guetlein was confirmed by the United States Senate on July 17, 
2025, as the Golden Dome for America Direct Reporting Program Manager 
(DRPM), with responsibility for all activities to deliver the next-
generation missile defense shield. I defer to the DRPM for further 
details concerning the development of the Golden Dome for America 
architecture.
    Mr. Bell. The United States has been at the forefront of advancing 
regional integration through research and development with Israel, 
contributing to the joint development and procurement of highly 
successful defense systems, including the Iron Dome, David's Sling, and 
Arrow systems.
    Last year, we witnessed the first two direct attacks from Iran 
targeting Israel. While these operational defense systems played a 
crucial role, we also saw significant support and cooperation from our 
regional allies.
    General Collins: Could you please provide details on the additional 
assets deployed to the region and assess their performance so far?
    General Collins. The response contains sensitive information and 
will be provided to the requestor by other means.
    Mr. Bell. In 2024, the President's supplemental aid request 
included significant funding for the procurement of Iron Beam, an 
Israeli-developed directed-energy air defense system designed to 
counter short-range rockets, drones, artillery, and mortar bombs.
    Could you provide an update on the current status of the Iron Beam 
program and explain how these funds are being utilized? Additionally, 
how do you envision the future of the U.S.-Israel cooperation in 
directed energy missile defense?
    General Collins. The response contains sensitive information and 
will be provided to the requestor by other means.
    Mr. Bell. How have NORTHCOM and MDA participated in the development 
of Golden Dome for America architecture?
    General Guillot. USNORTHCOM has remained in close coordination with 
MDA throughout the initial Golden Dome for America (GDA) development 
process. USNORTHCOM provided input to the Department of Defense during 
reference architecture development and are currently, in coordination 
with USSPACECOM, drafting additional operational requirements. NORAD 
and USNORTHCOM continue to provide operational perspectives to various 
agencies throughout the Department as GDA continues to mature.
    Mr. Bell. Are you confident that our homeland missile defense 
system remains ahead of evolving threats posed by North Korea and 
China?
    General Guillot. While I remain confident against the current 
intelligence-assessed threat, North Korea remains eager to transition 
their strategic weapons program from research and development to serial 
production and fielding. That process could rapidly expand North 
Korea's inventory and would challenge our missile defense capacity.
    The President's "Iron Dome for America" executive order clarified 
and expanded missile defense policy to include peer, near-peer, and 
rouge adversaries. Current U.S. Ballistic Missile Defense capabilities 
were designed and deployed to defend against rogue nations and provide 
limited conventional cruise missile defense. USNORTHCOM is working 
across the Department of Defense to ensure the capabilities of the 
Golden Dome meet policy objectives against the full spectrum of current 
and future intelligence-assessed threats.
