The ship was built as W. M. Irish, completed in April 1918, by the Bethlehem Shipbuilding Corp., Alameda, California. The tanker, assigned official number 216249, was operated by the Atlantic Refining Company, Philadelphia, Pennsylvania until acquired 20 January 1942 by the War Shipping Administration (WSA) at New Haven, Connecticut and allocated to the Army the same day for operation under a Transportation Corps agreement. On 23 May 1943 at Loa Angeles the ship was conveyed to the Soviet Union under lend lease which operated the vessel as Moskva until the ship was returned and placed under a WSA general agreement with Deconhil Shipping Company.[1]
Renamed Nausett on 29 October 1944, she was accepted by the Navy on a bareboat charter and commissioned at Pearl Harbor on 8 January 1945. On further inspection, necessary alterations were deemed too expensive to warrant the expenditure.[2]
In June, Nausett was placed in reduced commission pending her return to WSA on the West Coast. On 23 September 1945, she arrived at San Francisco, California, where she decommissioned and was delivered to WSA, on 12 October 1945. Twelve days later she was struck from the Navy Register.[2]
The ship was placed in the Suisun Bay Reserve Fleet on 12 October 1945 with a note that the ship had a breakdown on the way and had to be towed to the mooring. The vessel was purchased for scrap by American Iron & Metal on 27 November 1946 for $7,217.[1]
