Northrop Grumman Corp. has completed a successful preliminary design review (PDR) of the Relay Ground Station-Asia (RGS-A) for the U.S. Naval Information Warfare Center (NIWC) Pacific’s missile warning system. The PDR was completed one month ahead of schedule, demonstrating Northrop Grumman’s commitment to accelerating production processes to meet critical military needs. The company was awarded a $99.6 million five-year contract from NIWC Pacific last year to design, develop, integrate, test and deliver the relay ground station. RGS-A will be deployed to Guam and is scheduled to be installed by late 2025. Northrop Grumman’s advanced technologies will support missile-warning and missile-tracking satellites that protect the nation and its allies.
