Ballistic Missile Defense Midcourse Defense Segment
Abstract
The GMD is an element of the Missile Defense System (MDS) that provides combatant commands (CCMDs) with a continuously available (24 hours a day, 7 days a week, 365 days a year) capability to defend the Homeland against limited Intercontinental Ballistic Missile (ICBM) attacks. The GMD capability consists of GBI, GMD Fire Control system (GFC), GCN, IDT, and Ground Launch Support Systems (LSS). Each GBI delivers a single kill vehicle to defeat threat warheads in space during the midcourse phase of the ballistic trajectory. The GFC consists of fire control nodes in Fort Greely, Alaska (FGA) and Missile Defense Integration and Operations Center (MDIOC) Colorado Springs, Colorado. IDTs are currently located in FGA; Vandenberg Air Force Base, California (VAFB); Eareckson Air Station, Alaska (EAS); and Fort Drum, New York. LSS are currently located in FGA and VAFB. The GMD capability leverages integration of MDS sensors across the globe. Development objectives for GMD include: improve homeland defensive capability against an evolving threat that is increasing both in number of missiles and complexity of threat payloads; execute flight testing; modernize the GMD weapon system to enhance capability and increase reliability; provide fire control and communications; reliability testing and upgrades to sustain the current fleet; develop GBI software enhancements and service life extensions that improve reliability, capability, and discrimination; improve GMD models and simulations (M&S); and participate with other MDS assets in system ground tests.

- Increase in FY 2021 provides Congressional add for GMD reliability/Service Life Extension Program (SLEP) and reflects Congressional reductions for inadequate justification and future contracts preparation. Decrease in FY 2022 reflects manpower efficiencies and inflation adjustments and realignments for Next Generation Interceptor (NGI). Decrease in FY 2022 also reflects a reduced quantity of GBI removals and emplacements for LSS upgrades, as well as the realignment of GBI software development in FY 2022 due to the accelerated delivery of EKV software 24.0 in FY 2020 utilizing the Risk Reduction Congressional Plus-Up funds in the Improved Homeland Defense Interceptors Program Element, 0604874C.
