The USS Sioux (AT-75) was a Navajo-class fleet tug built for the United States Navy, laid down on 14 February 1942 by United Engineering Co. at Mare Island Navy Yard in San Francisco, California. She was launched on 27 May 1942 and commissioned on 6 December 1942. The vessel measured approximately 213 feet in length, with a beam of around 43 feet, and was designed for fleet support, particularly towing and salvage operations. During World War II, the USS Sioux actively participated in key Pacific campaigns. After a brief shakedown along the U.S. West Coast, she departed on 3 February 1943, towing YO-8 to Pearl Harbor, and then moved into the South Pacific war zone by June 1943. Her operations included supporting the New Georgia campaign, reinforcing Bougainville, and aiding raids on Kavieng and Rabaul. Notably, she was part of the support fleet during the Battle for Leyte Gulf and supported the Fast Carrier Task Force during air strikes on Japan in February 1945, including the Iwo Jima assault. On 14 May 1945, her gunners sank a Japanese Kaiten submarine in waters between Okinawa and the Western Carolines. Post-war, Sioux conducted towing duties in the Surigao Strait and between Leyte and Okinawa. She supported Operation Crossroads, the atomic bomb tests at Bikini Atoll, in 1946. Decommissioned in December 1946, she entered the Pacific Reserve Fleet but was recommissioned in 1952, serving in the Pacific until 1965, with deployments including nuclear tests, the Aleutian Islands, and the Far East. Her service extended into the Vietnam War era, where she performed surveillance and towing operations in the South China Sea, frequently visiting Vietnamese ports such as Da Nang and Cam Ranh Bay. On 30 October 1972, she was transferred to Turkey and renamed Gazal (A-587), remaining in service until December 2017. Throughout her career, USS Sioux earned four battle stars for World War II and eight for Vietnam, marking her as a notable vessel in U.S. naval history.
