The Missile Defense Agency awarded Boeing a three-year, $150 million contract modification to produce four additional boost vehicles for the Ground-based Midcourse Defense (GMD) system.

GMD is the only defense program capable of protecting the entire U.S. homeland, including Alaska and Hawaii, against long-range ballistic missile attacks.

As the prime contractor, Boeing designs, produces, integrates, tests and sustains all GMD components deployed across 15 time zones. Boeing also provides training, equipment production and operations support services.

Boeing manages the program in Huntsville and the work will be performed in Chandler, Ariz.
