USS Patroclus (ARL-19) was an Achelous-class repair ship, originally laid down as a U.S. Navy LST-542-class tank landing ship (LST-955) before being converted for repair duties during World War II. She was constructed at the Bethlehem-Hingham Shipyard in Hingham, Massachusetts, with her keel laid on 22 September 1944. Launched a month later on 22 October 1944, she was initially placed in reduced commission on 13 November 1944 to move to Baltimore for conversion. Following her transformation into a repair ship at the Bethlehem Key Highway Shipyard, she was commissioned in full on 17 April 1945. Following her shakedown in Chesapeake Bay, Patroclus departed the east coast on 22 May 1945, transiting the Panama Canal and heading to San Francisco for final outfitting. She then steamed westward, arriving at Saipan on 7 August 1945, where she joined Service Division 103 to provide repair support for landing craft. On 27 August, she proceeded to Tokyo Bay to support occupation forces, and notably witnessed the Japanese surrender on 2 September 1945. During her service in Tokyo Bay, she carried out repairs on various landing craft and support vessels, including LSMs, LCIs, LCSs, and LSTs. Patroclus’s active service in the Pacific ended on 7 April 1946, when she was relieved by USS Romulus. She departed Tokyo Bay on 8 April for the U.S. East Coast and was decommissioned on 2 October 1946, berthed at Green Cove Springs, Florida, as part of the Atlantic Reserve Fleet. She remained there until November 1951, when she was transferred to the 6th Naval District for conversion under the Military Assistance Program. Struck from the Naval Vessel Register on 22 August 1952, she was transferred to Turkey on 15 November 1952, where she served as TCG Basaran (A 582). The vessel was eventually scrapped in September 1993.
