The USS Ashtabula (AO-51) was a Cimarron-class fleet oiler constructed during World War II, serving the United States Navy from 1943 until her decommissioning in 1982. Built by Bethlehem Steel at Sparrows Point, Maryland, she was laid down on October 1, 1942, launched on May 22, 1943, and commissioned on August 7, 1943. Her design initially featured a length of approximately 310 feet, but in the 1960s, she became the lead ship of her class after a significant lengthening ("jumboization") that added a 400-foot midsection, boosting her cargo capacity and modernizing her appearance. Throughout her service, Ashtabula supported numerous wartime and peacetime operations across the Pacific and beyond. During World War II, she operated in the South Pacific, supporting fleet operations during the campaigns for the Marshall Islands, Marianas, and the Philippines. She participated in pivotal battles such as the Battle of the Philippine Sea, fueling carrier task forces engaged in these campaigns. Notably, she was torpedoed by Japanese aircraft in October 1944, which caused a 16-degree port list but was promptly corrected. She also sustained damage in April 1945 when her bow struck the seaplane tender Thornton, requiring repairs. Post-war, Ashtabula continued her vital role in fueling naval operations in Korea, Vietnam, and the broader Asia-Pacific region. She earned eight battle stars for WWII, four for Korea, and eight campaign stars for Vietnam, reflecting her extensive combat service. Her operational history includes supporting the evacuation of Hungnam, supplying ships during the Korean War, and participating in Vietnam War replenishment missions, including operations in the Gulf of Tonkin and Cambodia. In her later years, she underwent further modifications, including her jumboization in 1968, which increased her cargo capacity significantly. She remained active in various deployments until her decommissioning at Pearl Harbor on September 30, 1982. Subsequently, she joined the Reserve Fleet, was stricken from the Naval Vessel Register in 1991, and eventually used as a target ship in a SINKEX exercise in 2000, where she was heavily bombed and missile-attacked before sinking. Her service record and adaptations exemplify her long-standing significance as a key logistical vessel supporting U.S. naval operations across multiple conflicts.
