Defense of Guam Development
Abstract
The Missile Defense Agency (MDA) is developing a Missile Defense System for Guam defense against a range of missile threats. The Department of Defense (DoD) has undertaken studies on a range of missile defense architecture options, emphasizing effectiveness, survivability, and flexibility against an evolving threat. The architecture design includes integration efforts between MDA, U.S. Army (USA), and U.S. Navy systems (USN). MDA develops key weapon systems included in the DoD Architecture led by the Army in the Joint Program Executive Office. This Program Element supports PDI. In FY 2022, the 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, Aegis Guam System support, environmental studies, site design, activation and advanced planning. Starting in FY 2024, the program leverages the results of studies and analysis to continue to provide for developing and fielding distributed land-based launchers, distributed sensors, and integrated communications across Guam. The architecture acquisition process also provides increased Aegis Weapon System development for Guam integration, site activation, environmental protection, engineering, and interoperability activities to balance costs and associated risks. FY 2025 continues the advancements of FY 2024 leading up to an on-island flight experiment planned for early FY 2025. The FY 2025 end-state architecture also includes integration efforts between MDA, USA, and USN systems, which includes a 360 degree persistent integrated air and missile defense with distributed Mk-41 Vertical Launching Systems, and an Army Navy/Transportable Radar Surveillance and Control-6 (AN/TPY-6) to provide for the Defense of Guam. Guam Architecture System will be controlled by a Joint Command Center with additional Integrated Air and Missile Defense Battle Command System; Aegis Guam System; and Command and Control, Battle Management and Communications mission node providing local continuity of operations. Initial capability will be demonstrated on Guam in calendar year (CY) 2024, enhanced capability in CY 2029, and future additional capability in the 2030's.
