USS Acadia (AD-42) was a Yellowstone-class destroyer tender serving in the United States Navy, constructed by the National Steel and Shipbuilding Company in San Diego, California. Laid down on 14 February 1978 and launched on 28 July 1979, she was officially commissioned on 6 June 1981. The vessel measured approximately 550 feet in length, with a beam of about 75 feet, and displaced around 16,000 tons when fully loaded. She was designed to serve as a mobile repair and support platform for fleet ships, featuring extensive repair facilities, workshops, and berthing accommodations. After her commissioning, Acadia completed her shakedown cruise in August 1981, visiting Pearl Harbor and returning to San Diego. Throughout her early years, she primarily operated in the Pacific Fleet, providing repair services at San Diego and Pearl Harbor, and occasionally conducting training cruises, including midshipman training and refresher exercises. Her first overseas deployment began in January 1983, taking her across the Pacific to Yokosuka, Japan, and onward to the Indian Ocean and East Africa, where she performed repair and logistical support for ships operating in the Arabian Sea and Persian Gulf during tense regional conflicts. Acadia's service included notable wartime support during Operation Desert Shield and Desert Storm in 1990-1991, where she provided essential repair services, including the first outside-the-continental U.S. reload of shipboard Tomahawk missiles. She also played a critical role in repairing the guided missile cruiser Princeton after damage sustained during combat operations. Her support extended to the damaged frigate Stark and the amphibious assault ship USS Iwo Jima, demonstrating her vital role in forward-deployed naval operations. Decommissioned on 16 December 1994 and placed in reserve at Pearl Harbor, Acadia was struck from the Naval Register in 2007. She was ultimately sunk as a target during the Valiant Shield exercise off Guam on 20 September 2010, after being used as a target in a live-fire training exercise. USS Acadia's service exemplifies the critical support role of destroyer tenders in maintaining fleet readiness and operational capability over her three-decade career.
