Headquartered in Pohang, the Commander Air Wing Six is responsible for the operation of naval aircraft. South Korean naval flying started in 1951, with the reconstruction of a former USAF T-6 Texan for naval duties. In 1957, the ROK Navy established the Fleet Aviation Unit, which became the Fleet Air Wing in 1977 when the Navy strengthened its naval aviation force by acquiring Grumman S-2 Tracker ASW aircraft and Aérospatiale Alouette III helicopters. In 1986, the Fleet Air Wing was renamed the Air Wing Six.
