The Department of Defense, specifically the Naval Surface Warfare Center, is seeking proposals for Mobile at Sea Sensor System Support Services at Joint Base Pearl Harbor-Hickam (JBPHH) in Hawaii. The procurement aims to secure range support services for the MATSS vessel, which is crucial for naval operations and testing. Offerors must possess a Seaport contract to access the Seaport NxG portal for proposal submission, as all proposals will be accepted exclusively through this platform.
