The USS Tangier (AV-8) was a notable Maritime Commission type C-3 cargo ship, launched on 15 September 1939 as Sea Arrow and later converted into a seaplane tender for the United States Navy during World War II. As the first of the C-3 class to be built on the Pacific coast, Sea Arrow marked a significant revival of shipbuilding in that region, distinguished by its fireproof construction, high-pressure steam plant, and over half of its hull welded—a pioneering achievement demonstrating Pacific yards' capability to produce advanced vessels. Constructed by the Moore Dry Dock Company in Oakland, California, the ship was laid down on 18 March 1939 under MC hull 51. She was launched ahead of schedule, featuring a distinctive painting of giant eyes around her hawse pipes at her launch ceremony. Upon completion, she was delivered to the Maritime Commission and immediately acquired by the Navy, renamed Tangier, and commissioned on 25 August 1941 under Commander Clifton A. F. Sprague. Tangier’s service history began with her presence at Pearl Harbor during the attack on 7 December 1941, where she actively participated in anti-aircraft defense and rescue operations amid the chaos. She claimed hits on multiple enemy aircraft and a midget submarine, contributing to the defense efforts. Following Pearl Harbor, Tangier served as a seaplane tender in the Pacific, supporting reconnaissance and rescue missions across key locations such as New Caledonia, Espiritu Santo, and the Solomon Islands, including operations related to the Battle of the Coral Sea. Throughout the war, Tangier supported significant campaigns including the invasions of Wakde, Noemfoor, Biak, Morotai, and the Philippines, providing crucial air-sea rescue, reconnaissance, and anti-shipping operations with her Catalinas and Mariners. Her service earned her three battle stars. After the war, she participated in occupation duties in Japan and China before returning to the United States in 1946. Decommissioned in 1947, she remained in reserve until 1961, when she was struck from the Naval Vessel Register. Subsequently sold for mercantile use, she was renamed Detroit in 1962, converted into a car carrier/container ship, and operated by Sea-Land Service. Ultimately, in October 1974, she was sold for scrap and dismantled in Valencia, Spain. The USS Tangier’s distinguished wartime service and pioneering construction marked her as a significant vessel of World War II maritime history.
