Boeing Awarded $150 Million in Support of Ground-based Midcourse Defense System

Boeing was awarded a $150 million undefinitized contract modification to the development and sustainment contract (DSC) by the U.S. Missile Defense Agency (MDA) for the Ground-based Midcourse Defense (GMD) system.

The scope of work under the current DSC (HQ0147-12-C-0004/-19-C0004) includes development, fielding, test, systems engineering, integration and configuration management, equipment manufacturing and refurbishment, training and operations and sustainment for the Ground-based Midcourse Defense weapon system and associated support facilities.

Under this undefinitized modification (P00057), the Missile Defense Agency executes the procurement of four additional Configuration 2 Ground Based Interceptor (GBI) boost vehicles to maintain the fleet and flight test programs. The work will be performed in Chandler, Arizona, and the period of performance is from July 10, 2020, to July 30, 2023.

With this modification, the value of this contract, including options, is increased to $11.49 billion.

Ground-Based Midcourse Defense (GMD)

Ground-Based Midcourse Defense (GMD) is the United States’ anti-ballistic missile (ABM) system for intercepting incoming warheads in space, during the midcourse phase of ballistic trajectory flight.

The GMD system is a major component of the American missile defense strategy to counter ballistic missiles, including intercontinental ballistic missiles (ICBMs) carrying nuclear or conventional warheads. The system is the United States’ only operationally deployed missile defense program capable of defending the entire U.S. homeland (including Alaska and Hawaii) against long-range ballistic missile attacks.

The system provides early detection and tracking during the boost and midcourse phase, as well as target discrimination, precision intercept and destruction of the target through force of collision. GMD is an integral element of the U.S. Missile Defense Agency (MDA)’s layered ballistic missile defense (BMD) architecture.

The GMD system is deployed at Fort Greely, Alaska and Vandenberg Air Force Base, California comprising 44 GBI (Ground-Based Interceptor) interceptors.

GMD is administered by the Missile Defense Agency (MDA), while the operational control and execution is provided by the U.S. Army, and support functions are provided by the U.S. Air Force. As prime contractor, Boeing designs, produces, integrates, tests and sustains all GMD components deployed across 15 time zones.

Ground-Based Interceptor (GBI)

The Ground-Based Interceptor is a multi-stage, solid fuel booster with an Exoatmospheric Kill Vehicle (EKV) payload. When launched, the booster carries the EKV toward the target’s predicted location in space. Once released from the booster, the EKV uses guidance data transmitted from Ground Support & Fire Control System components and on-board sensors to close with and destroy the target warhead. The impact is outside the Earth’s atmosphere using only the kinetic force of the direct collision to destroy the target warhead.
