USNS Relentless (T-AGOS-18) was a Stalwart-class modified tactical auxiliary general ocean surveillance ship in service in the United States Navy from 1990 to 1993. Since 1998, she has been in commission in the National Oceanic and Atmospheric Administration (NOAA) fleet as the fisheries research ship NOAAS Gordon Gunter (R 336).

The U.S. Navy ordered Relentless from VT Halter Marine, Inc., on 20 February 1987. VT Halter Marine laid her down at Moss Point, Mississippi, on 22 April 1988, launched her on 12 May 1989, and delivered her to the U.S. Navy on 12 January 1990.

On the day of her delivery, the U.S. Navy placed the ship in non-commissioned service in the Military Sealift Command as USNS Relentless (T-AGOS-18). Like the other Stalwart-class ships, she was designed to collect underwater acoustical data in support of Cold War anti-submarine warfare operations against Soviet Navy submarines using Surveillance Towed Array Sensor System (SURTASS) sonar equipment. She operated with a mixed crew of U.S. Navy personnel and civilian merchant mariners.
