The USS Frontier (AD-25) was a Klondike-class destroyer tender built at the end of World War II for the United States Navy. Launched on 25 March 1945 by the Los Angeles Shipbuilding and Dry Dock Company in San Pedro, California, she was sponsored by Mrs. George M. Ravenscroft and commissioned on 2 March 1946. As a destroyer tender, the vessel was designed to provide logistical and maintenance support to fleet units, particularly destroyers, enabling extended operational readiness at sea. Following her shakedown cruise, the Frontier spent 1946 servicing units of the 1st Fleet, with her first overseas deployment occurring in early 1947 when she operated with Service Division 32 at Yokosuka, Japan, from January to May. She was decommissioned later that year on 29 September at Long Beach, California, entering a period of inactivation. Reactivated on 11 November 1951, the Frontier was recommissioned to support United Nations forces during the Korean War. She embarked Commander, Destroyer Flotilla 3, in May 1952 and deployed to Yokosuka, providing maintenance, logistical support, and acting as flagship for Destroyer Flotilla 3 throughout the Western Pacific until December. After an overhaul at Puget Sound Naval Shipyard, she returned to the region, continuing her duties primarily at Yokosuka and serving as flagship during her third Western Pacific tour, which lasted until December 1954. Throughout the 1950s, USS Frontier regularly supported fleet operations, participating in training exercises, maneuvers, and multiple Far Eastern deployments. She served as flagship of Destroyer Flotilla 3 during her tenure from October 1956 to March 1957 and again in 1960. Notably, her voyages included stops in Australia and other ports, emphasizing her role in maintaining U.S. naval presence and readiness in the Pacific. Decommissioned on 28 June 1968 at Naval Station San Diego, California, USS Frontier was struck from the Naval Register in December 1972. She was transferred to the Maritime Administration, sold for scrap in July 1974, and subsequently scrapped in April 1975. Her service history highlights her importance as a mobile logistical support vessel during critical periods of post-World War II and Cold War naval operations.
