When the Army's Water Transport Service was transferred to the Military Sea Transportation Service on 1 March 1950, she became the USNS Fred C. Ainsworth (T-AP-181). The ship served actively on troop transportation duties through the 1950s, including trans-Pacific operations during the Korean War. She participated in several Korean War operations including the Inchon landings.

Fred C. Ainsworth was placed out of service and transferred to the Maritime Administration (MARAD) on 2 November 1959, after which she was laid up in the National Defense Reserve Fleet. Her title was formally transferred to MARAD on 1 November 1960, and she was struck from the Naval Vessel Register 1 July 1961. On 1 March 1973 she was sold for scrap, but the deal was cancelled due to buyer default.
