U.S. Space Force’s Space Systems Command’s acquisitions branch at Peterson Space Force Base, Colo., has awarded Science Applications International Corp. [SAIC] a nearly $575 million ground-based radar maintenance and sustainment (GMASS) competitive contract.

“Work will be performed in Colorado Springs, Colorado; and other locations, and is expected to be completed by March 24, 2030,” DoD said in an Aug. 29 contract announcement. “This contract was a competitive acquisition and four offers were received.”

GMASS is to support upgraded early warning radars (UEWR) and Cavalier Space Force Station, N.D.’s AN/FPQ-16 Perimeter Acquisition Radar Attack Characterization System (PARCS), originally built by General Electric [GE] in the 1970s. The radars are to provide long-range missile warning and detect objects in orbit for the Space Surveillance Network’s “space domain awareness.”

GMASS is a follow-on to the Sustainment and Modification of Radar Sustainment Sensor (SMORS) contract. The Air Force awarded Northrop Grumman [NOC] an $866 million SMORS contract on June 1, 2018.
