The award came from Boeing Integrated Defense Systems, prime contractor for the Ground Based Midcourse Defense segment of the Missile Defense Agency Ballistic Missile Defense System.

Under the contract, Raytheon Integrated Defense Systems will continue to provide engineering services to ensure the sustainment infrastructure of the Upgraded Early Warning Radars at Beale Air Force Base, Calif., and Fylingdales in the United Kingdom, and the Cobra Dane radar at Shemya, Alaska.
