Ballistic Missile Defense Midcourse Defense Segment

Abstract

The GMD element of the Missile Defense System (MDS) 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 Ground Based Interceptor (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 and Missile Defense Integration and Operations Center (MDIOC) Colorado Springs, Colorado. IDTs are currently located in Fort Greely, Alaska (FGA): Vandenberg Air Force Base, California; Eareckson Air Station, Alaska; and Fort Drum, New York. 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 ground system, provide fire control and communications, reliability testing and upgrades to sustain the current fleet, develop GBI software enhancements that improve reliability, capability, and discrimination, improve GMD models and simulations (M&S), and participate with other MDS assets in system ground tests. The Missile Defense Agency (MDA) will continue development efforts in support of the delivery 64 operational silos, located at Fort Greely, Alaska (60 GBIs) and Vandenberg Air Force Base, California (4 GBIs).

Change Summary Explanation
Increase in FY 2020 provides the enacted congressional net increase of $147 million. $180 million increase provides for a more robust GBI reliability and Service Life Extension Program (SLEP) until replaced with NGI. $24 million increase provides for planning, analysis & assessment of MDS critical infrastructure cybersecurity. Advances Agency's compliance with DOD Cybersecurity Discipline Implementation Plan to protect MDA IT systems in the highly-contested cybersecurity threat environment. $57 million reduction eliminates RKV specific performance from GMD Fire Control Software. Increase in FY 2021 provides $96 million for EKV engineering, improving software performance, product sustainment, and purchase completion/delivery of two additional CE-II Block 1/C2 GBIs due to termination of the RKV program. $78 million funds the definitized contract value for the Development and Sustainment Contract which exceeded the government cost estimate used in prior submission.
