High Quality Content by WIKIPEDIA articles! USNS Indomitable (T-AGOS-7) was a United States Navy Stalwart class ocean surveillance ship in service from 1985 to 2002. Indomitable was laid down by the Tacoma Boatbuilding Company at Tacoma, Washington on 26 January 1985 and launched on 16 July 1985. She was delivered to the U.S. Navy on 26 November 1985. She was placed in non-commissioned service in the U.S. Navy's Military Sealift Command as a United States Naval Ship with a mixed Navy and civilian crew on 1 December 1985. Stalwart-class ships were originally designed to collect underwater acoustical data in support of Cold War anti-submarine warfare operations in the 1980s. Accordingly, Indomitable employed Surveillance Towed Array Sensor System (SURTASS) equipment on Cold War underwater surveillance duties.
