## What project MD65 buys

This program develops a Missile Defense System for the Defense of Guam against ballistic, hypersonic, and cruise missile threats as a high priority mission for the Department of War. The Missile Defense System will form a key part of strategic deterrence and supports the Department's PDI investments in the Indo-Pacific region. In FY 2022, the Missile Defense Agency (MDA) initiated studies and analysis, architecture development and siting analysis. FY 2023 continued architecture development and increased the development and modification of the distributed radar, AGS support, environmental studies, site design, activation and advanced planning. In FY 2024, the program leveraged the results of studies and analysis and continued developing and fielding of distributed land-based launchers, distributed sensors, and integrated communications across Guam. The acquisition approach is to balance costs and associated risks in order to provide increased AWS development for Guam integration, site activation, environmental protection, engineering, and interoperability. FY 2025 continued the advancements of FY 2024, with the completion of an on-island flight experiment in early FY 2025, continued Environmental Studies and Mitigations, and the continued the software development phase of the Aegis and Radar components. FY 2026 commences cybersecurity initiatives for the Command Center, development efforts for operationalizing the Initial Deployment of AGS in the new GDS architecture, continues environmental studies and mitigations, and continues the software development phase for the Aegis components. To defend Guam, the Missile Defense System mission activities are integrating systems from the MDA, U.S. Army (USA), U.S. Navy (USN), and U.S. Army Force. The Missile Defense System will leverage the MDA's S-band Missile Communication Radar (uplink and downlink) system, MDA's AGS, and USA's Lower Tier Air and Missile Defense Sensor to enable a full 360-degree field of view, eliminating blind spots and providing a layered and robust IAMD capability specifically tailored to protect Guam. The AGS employs the distributed Mk-41 Vertical Launching Systems, a single Army/Navy Transportable Radar Surveillance and Control Series 6 (AN/TPY-6) TAU, and Standard Missile uplink and downlink communications to transmit information to and from the missile during its flight.

**R-3 lines of work:** Product Development; Support; Management Services.

### Program Operations

$0.951 million decrease from FY 2026 to FY 2027 in PDI funding reflects the reduction of MDA Civilian labor and program management to execute the President's Executive Order (EO) 14210 to implement the Workforce Optimization and EO 14222 to synergize efforts and gain efficiencies. The reduction of funding for contract services is…
