The USS Bellerophon (ARL-31) was an Achelous-class landing craft repair ship constructed for the United States Navy during World War II. Originally intended to be an LST (Landing Ship, Tank), she was redesignated as a landing craft repair ship prior to construction. The vessel was laid down on December 12, 1944, by the Chicago Bridge & Iron Company in Seneca, Illinois, and launched on March 7, 1945. Sponsored by Hazel Nitherspoon, she was commissioned shortly thereafter on March 19, 1945. Following her commissioning, Bellerophon sailed to Mobile, Alabama, where she was placed out of commission on March 31 to undergo fitting-out as a repair ship. This conversion was completed during the summer of 1945, and she was recommissioned on July 21, 1945. After a shakedown cruise along the Gulf Coast, she returned to Mobile and prepared for deployment to the Pacific. Departing in early September, she transited the Panama Canal and traveled up the west coast, stopping at San Diego before arriving at Treasure Island, California, on October 3. There, she served as a repair ship for a newly formed boat pool. During late 1945 and early 1946, Bellerophon provided voyage repairs to Operation Magic Carpet ships and conducted conversions to enable attack cargo ships to serve as passenger carriers. In March 1946, she moved to Pearl Harbor, where she was assigned to the Commander, Amphibious Forces, Pacific Fleet, to repair amphibious warfare ships. She completed this duty in July 1946 and returned to the west coast, resuming repair work in San Diego. The vessel was placed out of commission at San Diego in September 1947 and remained in reserve for nearly three decades, with periods at San Diego and Bremerton, Washington. Her name was struck from the Naval Vessel Register in October 1977, and she was sold for scrapping on June 20, 1980. The USS Bellerophon thus served as a vital repair vessel during the closing months of World War II and the immediate post-war period, playing a crucial role in maintaining amphibious and operation ships during her active service.
