POLICY JUSTIFICATION

Korea--Precision Guided Munitions

    The Republic of Korea has requested to buy three thousand nine 
hundred fifty-three (3,953) Joint Direct Attack Munition (JDAM) 
Guidance Kits, KMU-556 for GBU-31; one thousand nine hundred eighty-one 
(1,981) JDAM Guidance Kits, KMU-557 for GBU-31, GBU-56; one thousand 
one hundred seventy-nine (1,179) JDAM Guidance Kits, KMU-572 for GBU-
38; and one thousand seven hundred fifty-five (1,755) FMU-139 Fuze 
Systems. Also included are DSU-42/B Detectors, Laser Illuminated Target 
for GBU-56; weapon spare parts, components and accessories; weapons 
training aids, devices, and spare parts; U.S. Government and contractor 
engineering, technical assistance, and logistical support services; and 
other related elements of logistical and program support. The estimated 
total cost is $258 million.
    This proposed sale will support the foreign policy goals and 
national security objectives of the United States by helping to improve 
the security of a Major Non-NATO ally that continues to be an important 
force for political stability, peace, and economic progress in the 
Indo-Pacific region.
    The proposed sale will improve the Republic of Korea's capability 
to meet current and future threats by increasing available stores of 
munitions on the Korean Peninsula in support of Alliance Operations 
Plans (OPLANs), as well as to fulfill conditions outlined by the 
Condition-Based Operational Control (OPCON) Transition Plan. The 
Republic of Korea will have no difficulty absorbing these articles into 
its armed forces.
    The proposed sale of this equipment and support will not alter the 
basic military balance in the region.
    The principal contractor will be Boeing Corporation, St Louis, 
Missouri. There are no known offset agreements proposed in connection 
with this potential sale.
    Implementation of this proposed sale will not require the 
assignment of any additional U.S. Government or contractor 
representatives to the Republic of Korea.
    There will be no adverse impact on U.S. defense readiness as a 
result of this proposed sale.

36(b)(1) of the Arms Export Control Act
Annex
Item No. vii
    (vii) Sensitivity of Technology:
    1. The Joint Direct Attack Munition (JDAM) is a guidance kit that 
converts existing unguided free-fall bombs into an accurate, adverse 
weather ``smart'' munition. The Guidance Set consists of a Tail Kit, 
which contains the Inertial Navigation System (INS) and a Global 
Positioning System (GPS), a set of Aerosurfaces and an umbilical cover, 
which allows the JDAM to improve the accuracy of unguided, General 
Purpose bombs. The JDAM weapon can be delivered from modest standoff 
ranges at high or low altitudes against a variety of land and surface 
targets during the day or night. The JDAM is capable of receiving 
target coordinates via preplanned mission data from the delivery 
aircraft, by onboard aircraft sensors (i.e., FLIR, Radar, etc.) during 
captive carry, or from a third-party source via manual or automated 
aircrew cockpit entry. The Guidance Set, when combined with a warhead 
and appropriate fuze, forms a JDAM Guided Bomb Unit (GBU).
    (a) The KMU-572 is the tail kit for a GBU-38 500LB JDAM.
    (b) The KMU-556 is the tail kit for a GBU-31 2,000LB Mk-84 (General 
Purpose bomb body) JDAM.
    (c) The KMU-557 is the tail kit for a GBU-31/-56 2,000LB BLU-109 
(General Purpose bomb body) JDAM.
    2. The Laser JDAM (GBU-56) is a 2,000LB JDAM that incorporates all 
the capabilities of the JDAM guidance tail kit and adds a DSU-42/B 
precision laser guidance set. The DSU-42/B sensor gives the weapon 
system an optional semi-active laser seeker. The addition of the DSU-
42/B laser sensor combined with additional cabling and mounting 
hardware turns a GBU-31 JDAM into a GBU-56 LJDAM. The DSU-42/B consists 
of a laser spot tracker, a cable connecting the DSU-42/B to the basic 
JDAM guidance set, a cable cover, cable cover tie-down straps, modified 
tail kit door and wiring harness, and associated modified JDAM software 
that incorporates navigation and guidance flight software to support 
both LJDAM and standard JDAM missions. The DSU-42/B adds the 
flexibility to strike targets of opportunity, including mobile and 
moving targets, to an already accurate adverse weather GPS/INS guided 
JDAM.
    3. The Joint Programmable Fuze (JPF) FMU-139D/B is a multi-delay, 
multi-arm and proximity sensor compatible with general purpose blast, 
frag and hardened-target penetrator weapons. The JPF settings are 
cockpit selectable in flight when used numerous precision-guided 
weapons. It can interface with the following weapons: GBU-31, GBU-38, 
and GBU-56.
    4. The highest level of classification of defense articles, 
components, and services included in this potential sale is SECRET.
    5. If a technologically advanced adversary were to obtain knowledge 
of the specific hardware and software elements, the information could 
be used to develop countermeasures that might reduce weapon system 
effectiveness or be used in the development of a system with similar or 
advanced capabilities.
    6. A determination has been made that the Republic of Korea can 
provide substantially the same degree of protection for the sensitive 
technology being released as the U.S. Government. This sale is 
necessary in furtherance of the U.S. foreign policy and national 
security objectives outlined in the Policy Justification.
    7. All defense articles and services listed in this transmittal 
have been authorized for release and export to the Republic of Korea.
