     SEC. __. GAO STUDY AND REPORT ON INTENTIONAL DISRUPTION OF 
                   THE NATIONAL AIRSPACE SYSTEM.

       (a) Study.--The Comptroller General of the United States 
     (in this section referred to as the ``Comptroller General'') 
     shall conduct a study on the vulnerability of the National 
     Airspace System to potential disruptive operations by any 
     person, party, or entity (in this section referred to as 
     ``adversaries'') exploiting the electromagnetic spectrum and 
     security vulnerabilities in the Aircraft Communications, 
     Reporting and Addressing System (ACARS) and Controller Pilot 
     Data Link Communications (CPDLC). Such study shall include an 
     analysis of--
       (1) the extent to which adversaries can engage in denial of 
     service attacks and electromagnetic spectrum interference 
     against--
       (A) the National Airspace System; and
       (B) high-traffic international routes of economic and 
     strategic importance to the United States;
       (2) the Federal Government's efforts, to date, to prevent 
     and prepare for such denial of service attacks and spectrum 
     disruptions;
       (3) the feasibility of mitigating the vulnerabilities 
     through cybersecurity and other upgrades to the Aircraft 
     Communications, Reporting and Addressing System and 
     Controller Pilot Data Link Communications;
       (4) whether the Federal Aviation Administration is 
     requiring sufficient cybersecurity and electromagnetic 
     spectrum defenses to address denial of service attacks and 
     other risks in new technologies it mandates be used on 
     aircraft; and
       (5) any other item determined appropriate by the 
     Comptroller General.
       (b) Report.--
       (1) To congress.--
       (A) In general.--Not later than 18 months after the date of 
     enactment of this Act, the Comptroller General shall submit 
     to the Committee on Armed Services, the Committee on 
     Commerce, Science, and Transportation, and the Select 
     Committee on Intelligence of the Senate and the Committee on 
     Armed Services, the Committee on Transportation and 
     Infrastructure, and the Permanent Select Committee on 
     Intelligence of the House of Representatives a report 
     containing the results of the study conducted under 
     subsection (a), together with recommendations for such 
     legislation and administrative action as the Comptroller 
     General determines appropriate.
       (B) Unclassified form.--In preparing the report under 
     subparagraph (A), the Comptroller General shall ensure that 
     any classified information is only in an addendum to the 
     report and not in the main body of the report.
       (2) Public availability.--The Comptroller General shall 
     post the report submitted under paragraph (1) on the public 
     internet website of the Government Accountability Office at 
     the time of such submission, but shall not include any 
     classified addendum included with such report.
