The USS Mindanao (ARG-3) was a Luzon-class internal combustion engine repair ship constructed during World War II to support naval operations in the Pacific Theater. Originally laid down as the liberty ship SS Elbert Hubbard on 11 April 1943 by the Bethlehem-Fairfield Shipyard in Baltimore, Maryland, she was launched on 13 May 1943 and acquired by the U.S. Navy on 20 May 1943. She was officially commissioned as USS Mindanao on 6 November 1943. The vessel measured approximately 441 feet in length, with a beam of about 62 feet, and was powered by internal combustion engines designed for repair and maintenance duties. After a shakedown in Chesapeake Bay, she joined Task Group 29.7 and traveled across the Pacific, arriving at Nouméa, New Caledonia, in late January 1944. Throughout her service, USS Mindanao provided essential engine repair services to ships supporting the island-hopping campaigns, including operations around Espiritu Santo, Manus, and later Ulithi. During the Battle of Okinawa, she played a vital role in preparing ships for the campaign, serving until October 1945. A notable event in her service history was her proximity to the explosion of the ammunition ship Mount Hood on 10 November 1944, which caused extensive damage to her superstructure and resulted in 82 crew members killed and 98 wounded. Despite this, she was repaired and continued her vital repair duties. After the war, USS Mindanao returned to the United States, decommissioned on 17 May 1947, and was placed in the Atlantic Reserve Fleet. She remained in reserve until 1961 when she was struck from the Naval Vessel Register and transferred to the Maritime Commission. In her later years, she served as part of the National Defense Reserve Fleet and was ultimately scuttled on 11 November 1980 off Daytona Beach, Florida, to serve as an artificial reef. Her sinking provided a habitat for marine life and is a notable example of post-war ship disposal through reef creation.
