The USS Trinity (AO-13) was a Patoka-class replenishment oiler built for the United States Navy, notable for its role in fueling and supporting naval operations from the early 1920s through World War II. Laid down on 10 November 1919 at Newport News, Virginia by the Newport News Shipbuilding and Drydock Company, she was launched on 3 July 1920 and commissioned on 4 September 1920. The vessel measured approximately 531 feet in length with a beam of around 68 feet, designed to carry large quantities of fuel oil and supplies necessary for fleet operations. Initially, Trinity conducted voyages to the Mediterranean, delivering general stores and fueling ships around Valletta, Malta, Split, and Venice. After a brief period of decommissioning in 1923, she was recommissioned in 1938, reflecting the Navy’s efforts to expand and modernize its fleet amid rising global tensions. During the late 1930s and early 1940s, Trinity operated primarily along the U.S. East Coast, in the Caribbean, and later in the Pacific, supplying oil to bases and ships from Guantanamo Bay to the Philippines. Her service took a critical turn in December 1941, just after the outbreak of World War II in the Pacific. Trinity was at Sangley Point, Philippines, when she received news of Japan’s hostilities and quickly departed Manila with other ships. She then supported Allied efforts in Southeast Asia and Australia, fueling ships at Borneo, Timor, and Darwin. Notably, she was attacked by Japanese submarine I-123 in January 1942 near Darwin, Australia; the attack missed, but the incident underscored the war’s dangers. Throughout 1942-1945, Trinity operated extensively in the Southwest Pacific, including New Guinea and the Philippines, providing vital fuel supplies to Allied ships. She played an essential logistical role in the Pacific Theater, supporting campaigns in New Guinea, Manus, and Leyte. After the war, she was decommissioned on 28 May 1946, struck from the Navy list, and eventually sold in 1951, when she was renamed Seabeaver. Trinity earned one battle star for her World War II service, signifying her vital contribution to wartime logistics and operations.
