Following shakedown in Chesapeake Bay, Patroclus departed the east coast 22 May 1945, transited the Panama Canal, and steamed to San Francisco for final outfitting. Steaming westward 2 July, the landing craft repair ship arrived at Saipan 7 August, and reported for duty with Serv Div 103. On 27 August, she continued on to Tokyo Bay, to provide repair facilities for occupation force vessels. Assigned to Tokyo Bay, she witnessed the formal surrender of Japan on 2 September, then commenced repair work on all LSMs, LCIs, LCSs, and LSTs in the area. On 7 April 1946, Patroclus was relieved by USS Romulus and on 8 April, she departed for the east coast of the United States and inactivation.[3]
Decommissioned 2 October 1946, Patroclus was berthed at Green Cove Springs, Florida, as a unit of the Atlantic Reserve Fleet until November 1951. Then, transferred to the custody of the 6th Naval District, she underwent conversion prior to transfer under the Military Assistance Program. Struck from the Naval Vessel Register 22 August 1952, she was transferred to Turkey, on 15 November 1952, where she served that nation as TCG Basaran (A 582).[3] She was scrapped in September 1993.[2]
