The USS Mark (AG-143) was originally constructed as an Army FS-type aircraft repair vessel, designated FS-214, built by Higgins Industries in New Orleans, Louisiana. Completed in December 1944, the ship was designed with a covered well deck to serve as a workshop for aircraft repairs, supporting an embarked Aircraft Maintenance Unit. A notable incident occurred on 13 April 1945, when the ship's starboard engine exploded. Civilian Chief Engineer Albert M. Boe heroically remained at his post despite fatal burns, ultimately sacrificing his life to shut down the engines. He was posthumously awarded the Merchant Marine Distinguished Service Medal, and a later ship was named in his honor. Toward the end of World War II, the vessel was renamed Colonel Raymond T. Lester, after an Army Air Corps officer. The U.S. Navy acquired her at Subic Bay, Philippines, on 30 September 1947, commissioning her on 2 December 1947. Initially serving in the Subic–Sangley Ferry Service, she was reclassified as AKL-12 on 13 March 1949, functioning as a light cargo ship within the Service Force of the 7th Fleet. Her role involved transporting cargo and passengers among fleet units in the Philippines. In 1956, the ship was placed out of service but continued operations from Subic Bay. With increasing U.S. military activity in Southeast Asia during the early 1960s, her resupply missions extended to South Vietnam. She was placed in a commissioned status on 1 October 1965 and, by June 1966, operated full-time in the combat zone, conducting supply runs and water surveys in the Mekong Delta region as part of operations supporting U.S. efforts in Vietnam. From 1966 to 1969, the USS Mark played a vital logistical role, ensuring the movement of supplies to riverine and coastal forces engaged in Operation Game Warden and Market Time. On 1 July 1971, she was transferred to Taiwan, serving in the Republic of China Navy as the intelligence-gathering ship Yung Kang (AKL 514). The vessel was sold outright on 1 May 1976, ending her distinguished service history.
