Missile Defense: Further Collaboration with the Intelligence Community Would Help MDA Keep Pace with Emerging Threats, Report to Congressional Committees [open pdf - 2MB]
From the GAO [Government Accountability Office] Highlights: "MDA [Missile Defense Agency] is developing missile defense capabilities to defend the United States, deployed forces, and regional allies from missile attacks. However, missile threats continue to emerge, as adversaries continue to improve and expand their missile capabilities. The National Defense Authorization Act for Fiscal Year 2012 included a provision that GAO annually assess and report on the extent to which MDA has achieved its acquisition goals and objectives, and include any other findings and recommendations. This report is a public version of a classified report GAO issued in May 2019, which addresses (1) the challenges MDA and the defense intelligence community face in meeting the agency's threat assessment needs and (2) the extent to which MDA engages the defense intelligence community on missile defense acquisitions. GAO reviewed MDA's threat-related acquisition processes and interviewed relevant officials from the defense intelligence community, MDA, test community, and warfighters. Information deemed classified by DOD has been omitted."
