Budget Figures
$200.6M discretionary + $247.0M one-time reconciliation. Discretionary change vs FY2025 enacted: +10.1%.
Two official figures, one label— reconciled below
Fiscal Receipts uses P-1/R-1 workbook total obligation authority (TOA) as the headline figure sitewide. The workbook TOA includes budget rows (such as advance procurement) that the R-2/P-40 J-book program line excludes. How the two bases relate →
FY26 Request · $447.6M TOA − $200.6M J-book line = 247.0M (447.6 − 200.6 = 247.0)
Figures in the sentence are rounded for reading; the parenthesised arithmetic is the same subtraction in USD millions, at the precision where it closes.
FY2026 award data is a partial year — USASpending awards are reported on a rolling basis and the fiscal year does not close until September 30. why partial FY2026 data? →

Description
Mission — Hypersonic Defense
Strategic competitors and both homeland and regional adversaries are heavily investing in offensive and defensive hypersonic capabilities, and currently have operational hypersonic strike and defensive systems deployed. These are challenging realities of the emerging missile threat environment that United States (U.S.) Missile Defense policy, strategy, and capabilities must address. These adversaries continue to expand the capability and capacity of their offensive and defensive hypersonic missile inventories for both strategic and regional hypersonic missiles. Near Peer/Peer nations have also demonstrated hypersonic missiles in recent flight tests. The Hypersonic Defense program element includes: execution of the systems engineering activities; upgrade of existing systems; investment in new technologies; and development of new regional defensive capabilities and maturation for delivery in 2032. The Missile Defense Agency's Hypersonic Missile Defense strategy includes leveraging existing systems, delivering an initial regional layered defense capability, and increasing defense capabilities in the future. Activities enabling this strategy are as follows: - Develop a regional Glide Phase Interceptor capability to engage hypersonic threats during the glide phase of flight and other threats in multi-mission areas. The Preliminary Design Review is planned in FY 2028, Kill Vehicle (KV) demonstration in 2029 and delivery of 12 tactical missiles in 2032. - Conduct early analysis and requirement to integrate into Golden Dome communications architecture. - Integrate existing overhead sensors such as the Hypersonic and Ballistic Tracking Space Sensor, as well as new technologies. - Execute systems engineering for Hypersonic Defense including architecture analysis, technology prioritization, requirements development, planning and analysis. - Partner with the Services and other agencies to leverage work on common technologies, test infrastructure, weapon development, testing, and war-gaming. - Cooperatively develop the Glide Phase Interceptor with Japan. Rapidly evolving rogue and peer missile threats have led to a change in national defense policy. The President's January 27, 2025, Executive Order established a goal of protecting the U.S. citizens, safeguarding critical infrastructure, and securing second-strike capability against missile attack from any adversary. The Missile Defense Agency is responding with speed and intensity to deliver next-generation missile defenses to protect the U.S. against ballistic, hypersonic, cruise, and other advanced missile threats. This program submission reflects changes necessary to meet this evolving mission space.

Strategic competitors and both homeland and regional adversaries are heavily investing in hypersonics, both offense and defense, and currently have operational hypersonic strike and defensive systems deployed. These are challenging realities of the emerging missile threat environment that United States Missile Defense policy, strategy, and capabilities must address. These adversaries continue to expand the capability and capacity of their offensive and defensive hypersonic missile inventories for both strategic and regional hypersonic missiles. Near Peer/Peer nations have also demonstrated hypersonic missiles in flight tests. The HD program element includes executing systems engineering activities, upgrading existing systems, investing in new technologies and maturation, and developing new regional defensive capabilities. Missile Defense Agency's (MDA) counter hypersonic threats strategy includes leveraging existing systems, delivering an initial regional layered defense capability, and increasing defense capabilities in the future. Activities enabling this strategy are the following: - Develop a regional Glide Phase Intercept capability to engage hypersonic threats during the glide phase of flight and other threats of multi-mission areas. - Develop requirements to integrate into Golden Dome communication architecture. - Execute systems engineering for HD, including architecture analysis, technology prioritization, requirements development, planning, and analysis. - Partner with the Services and other agencies to leverage work on common technologies, test infrastructure, weapon development, testing, and war-gaming. - Cooperatively develop the Glide Phase Interceptor with Japan.
Mission — Program Wide Support
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 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; 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; therefore, fluctuates per PE by fiscal year based on the total Agency budget in that fiscal year.
Justification
Accomplishments & Planned Programs (2)
Regional Hypersonic Missile Defense Capability
Develop and deliver a defensive capability to engage and defeat regional hypersonic threats during the glide phase of flight using the proven Aegis Weapon System as the point of departure for missile employment. This will provide an additional layer of regional hypersonic defense from an Aegis ship, virtualized Aegis platform, or other fire control solution; which also complements the Sea-Based Terminal capability by extending the battlespace. The defensive capability includes the development of a Glide Phase Interceptor missile that reduces the operational seam currently used by hypersonic threats to fly between air defense and ballistic missile defense systems. The effort also includes updates to the Aegis Weapon System for planning, tracking and conducting remote engagements against hypersonic threats within the Missile Defense System as well as conducting studies and advancing hypersonic capability to legacy Aegis Weapon Systems and future launch and fire control systems. It also includes urgently producing and fielding hypersonic defense capabilities. These capabilities developed based on the starting point of the proven Aegis Weapon System will be adaptable to non ship-based platforms as they are developed. This accomplishment will perform Systems Engineering, architecture analysis, modeling and simulation (M&S), advanced hypersonic technology development, and integrate the new capability into the Missile Defense System. Recurring accomplishments: Regional Glide Phase Interceptor Missile - Development of feasibility data which supports missile subassembly requirement development. - Conduct missile legacy component assessments to support the initial concept design that will house and use the legacy components. Mission Assurance data is required to justify the operating environments the legacy components will be in and any modifications necessary to support the Glide Phase Interceptor mission. - Conduct element-level M&S development to lay the foundation of the design and ensure early subassembly design concepts support integrated missile performance to the Glide Phase Interceptor requirements. - Continue development and maturation of Critical Technology Elements across limited areas of the all up round. - Execute design activities for hardware, software, support systems, human interfaces, cybersecurity, and mechanical and electrical interfaces. - Purchase limited materials to support proof of design and design verification testing in support of establishing the preliminary interceptor design. - Conduct hypersonic threat development and lethality development. - Conducted international cooperative development through agreements between United States and Japan. - Explore capability against multi-mission threats. - Integrate Glide Phase Intercept into Golden Dome communication architecture.
