The USNS Cheyenne (T-AG-174) was a Phoenix-class miscellaneous auxiliary vessel acquired by the U.S. Navy in 1962. Originally constructed as a Victory ship named SS Middlesex Victory, she was built at the Oregon Shipbuilding Corporation in Portland, Oregon, and launched on June 26, 1945. During World War II, she operated under the Pacific-Atlantic Steamship Company, delivering vital supplies to support Allied military efforts. In 1947, she was renamed SS Wyoming after being sold to the States Steamship Company of Tacoma. In 1963, she was repurposed for naval service as USNS Cheyenne (T-AG-174), designated as a Special Project Ship and crewed by civilians from the Military Sea Transportation Service (MSTS). Her primary role was to act as a cargo and delivery vessel, transporting parts and supplies to U.S. Navy ships and stations across the Asian theater. From her base in the Philippines, Cheyenne operated until the late 1960s, supporting U.S. military logistics. In 1966, her home port was shifted to Pusan, Korea, where she was crewed by Korean merchant sailors, including her notable master, a former Republic of Korea Navy captain known as "Speedy Pak." During this period, she was part of a small fleet, including other cargo ships and U.S. LSTs, primarily supporting operations in Vietnam. The vessel was struck from the Navy list in 1973 and subsequently disposed of by the Maritime Administration sale in May 1973. She was scrapped in August of the same year. Throughout her service, Cheyenne played a vital logistical role in supporting U.S. military operations in the Pacific and Southeast Asia, exemplifying the vital function of auxiliary cargo ships in wartime logistics and maritime support.
