Description

Mission Improved Homeland Defense Interceptors

The Improved Homeland Defense Interceptors provides the development, integration, and testing of a Next Generation Interceptor AUR consisting of an integrated boost vehicle/multiple kill vehicle payload capable of surviving both natural and hostile environments while countering the allocated threat space. Meeting the United States Northern Command's (USNORTHCOM) Operational Needs for Homeland Defense. The Next Generation Interceptor will provide USNORTHCOM a solution that is lethal across the specified threat space; upgradeable to address future and advancing threats; and fully integrated into the Ground-Based Midcourse Defense (GMD) Weapon System (GWS). The Missile Defense Agency (MDA) issued a Request for Proposal in FY 2020 and competitively awarded two best value contracts on March 24, 2021, for a Next Generation Interceptor acquisition. The MDA maintained the competitive environment through Preliminary Design Reviews (PDR) and Knowledge Point (KP) 1 in FY 2024 to reduce technical risk, encourage schedule acceleration, and support the Department's ability to field a system capable of negating the expanding threat. With the PDR/KP #1 data, the MDA selected a single Prime contractor for continued development through a CDR; qualification; integration with the GWS; ground cyber and flight testing; and AUR production. 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 United States (U.S.) citizens, safeguarding critical infrastructure, and securing second-strike capability against missile attack from any adversary. The MDA 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.

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 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; therefore, fluctuates per PE by FY based on the total Agency budget in that FY.

Mission Next Generation Interceptor Development (NGI)

The Improved Homeland Defense Interceptors provides the development, integration, and testing of a Next Generation Interceptor AUR consisting of an integrated boost vehicle/multiple kill vehicle payload capable of surviving both natural and hostile environments while countering the allocated threat space. Meeting the United States Northern Command's (USNORTHCOM) Operational Needs for Homeland Defense. The Next Generation Interceptor will provide USNORTHCOM a solution that is lethal across the specified threat space; upgradeable to address future and advancing threats; and fully integrated into the Ground-Based Midcourse Defense (GMD) Weapon System (GWS). The Missile Defense Agency (MDA) issued a Request for Proposal in FY 2020 and competitively awarded two best value contracts on March 24, 2021, for a Next Generation Interceptor acquisition, which covers the development, integration, and testing of an AUR consisting of an integrated boost vehicle/multiple kill vehicle payload. The MDA maintained the competitive environment through Preliminary Design Reviews (PDR) and Knowledge Point (KP) 1 in FY 2024 to reduce technical risk, encourage schedule acceleration, and support the Department's ability to field a system capable of negating the expanding threat. With the PDR/KP #1 data, the MDA selected a single Prime contractor for continued development through a CDR; qualification; integration with the GWS; Peculiar Support Equipment (PSE) to support AUR emplacement and in-silo maintenance; ground cyber and flight testing; and AUR production.

What it is

  • The Improved Homeland Defense Interceptors program (budget code 0604874C) is run by the Missile Defense Agency (MDA) and funds the development, integration, and testing of a Next Generation Interceptor — an all-up-round (AUR) missile consisting of an integrated boost vehicle and multiple kill vehicle payload designed to survive both natural and hostile environments while countering the assigned threat.
  • The interceptor is intended to give U.S. Northern Command (USNORTHCOM) a solution that is lethal across the specified threat space, upgradeable to address future threats, and fully integrated into the existing Ground-Based Midcourse Defense (GMD) Weapon System.
  • The MDA issued a Request for Proposal in fiscal year 2020 and competitively awarded two best-value contracts on March 24, 2021, for the Next Generation Interceptor acquisition.
  • The agency maintained competition through Preliminary Design Reviews and Knowledge Point 1 in fiscal year 2024, then selected a single prime contractor for continued development through Critical Design Review, qualification, integration with the GMD Weapon System, ground/cyber and flight testing, and AUR production.
  • The program has two projects: Next Generation Interceptor Development (project MD80) and Program Wide Support (project MD40), which covers non-headquarters management costs allocated across MDA activities on a pro-rata basis.
  • Program Wide Support funds MDA-wide functions such as government civilians and contract support, physical and technical security, facility leases and maintenance, and oversight of the broader Missile Defense System.

Why it matters

  • This is a large, high-priority research line: fiscal year 2024 actual spending reached about $2.07 billion (in USD thousands, $2,073,886).
  • For fiscal year 2025, Congress enacted about $1.67 billion ($1,670,256 thousand).
  • The fiscal year 2026 total request is about $1.64 billion ($1,637,414 thousand), made up of a $1,582,414 thousand discretionary request plus a $55,000 thousand reconciliation request.
  • That fiscal year 2026 total represents a decrease of about $32.8 million ($32,842 thousand), or roughly 2 percent, from the fiscal year 2025 level.
  • The program is tied to national defense policy: a Presidential Executive Order dated January 27, 2025, established a goal of protecting U.S. citizens and critical infrastructure and securing second-strike capability against missile attack from any adversary, and this budget submission reflects changes to meet that mission.

Key players

  • The Missile Defense Agency (MDA) is the organization responsible for the program.
