Guam Defense Development

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.

PWS contains non-headquarters management costs in support of Missile Defense Agency (MDA) functions and activities across the entire Missile Defense System. These functions include Government Civilians and Contract Support Services. This effort provides integrity and oversight of the Missile Defense System as well as supports MDA in the development and evaluation of technologies that will respond to the changing threat. Additionally, PWS includes personnel to support global deployments performing deployment site preparation and activation, and provides facility capabilities for MDA Executing Agent locations worldwide. Other MDA wide costs include: physical and technical security; civilian drug testing; audit readiness; the Science, Technology, Engineering, and Mathematics (STEM) program; legal services and settlements; travel and agency training; office, equipment, vehicle, and warehouse leases; utilities and base operations across multiple geographic locations; commercial and ancillary facility services; management of all facility aspects regardless of lifecycle stage; supplies and maintenance; compliance with statutory environmental requirements; data and unified communications support; materiel and readiness and central property management of equipment; Facilities Sustainment, Restoration and Modernization (FSRM) program (formerly Real Property Maintenance) to keep the Department's inventory of facilities in good working order; and similar operating expenses. PWS is allocated on a pro-rata basis across most Agency PEs and, therefore, fluctuates per PE by FY based on the total Agency budget in that FY.

Guam on-island Cyber team coordinates local network defense activities and assumes responsibility to defend onsite assets from active or imminent cyberspace threats in the event of degraded communication conditions. This Budget Project provides the oversight and inter-Agency/Service coordination for Cyber activities needed for integrating a capability to defend Guam against ballistic, hypersonic, and cruise missile attack.
