USNS Impeccable (T-AGOS-23) is an Impeccable-class ocean surveillance ship acquired by the U.S. Navy in 2001 and assigned to Military Sealift Command's Special Missions Program.
Impeccable was built by American Shipbuilding, Tampa, Florida. The contract was awarded on 28 March 1991. The ship's keel was laid down on 15 March 1992, but the Tampa shipyards went bankrupt by November 1993. On 3 December 1992, the General Accounting Office published a report that concluded that T-AGOS 24–27 should not be built. Shortly afterwards the government decided to discontinue this class of ships, but the Impeccable was to be completed as the sole ship in its class. The hull was towed to Gulfport, Mississippi, in 1995 where it was finished by Halter Marine Inc. She was launched on 28 August 1998 and was delivered to the Navy on 22 March 2001 which assigned her to the Military Sealift Command (MSC) Special Missions Program.
The ship is a designated T-AGOS vessel built to tow a Surveillance Towed Array Sensor System. The ship's catamaran-type small waterplane area twin hull (SWATH) design prevents the vessel from rolling in heavy seas and gives additional deck space for storing the acoustic equipment.
The mission of Impeccable is to directly support the Navy by using SURTASS passive and active low frequency sonar arrays to detect and track undersea threats.
