Under changing designations, the wing has been the main USAF flying force at Kadena for over 50 years. The wing has maintained assigned aircraft, crews, and supporting personnel in readiness to respond to orders from Fifth Air Force and Pacific Air Forces. The wing initially was flying three squadrons of North American F-86 Sabre: the 12th, 44th and 67th Fighter Squadrons.
