The gunnery schools were located at Yuma AFB, Arizona (17th TTS), and later moved to MacDill AFB, Florida where the training continued over the Gulf of Mexico. With the move to Florida, the 3d TTS was formed at George AFB, California which performed training over the Mojave Desert in Southern California. Additional units were located at Biggs AFB, near El Paso, Texas (1st TTS) and the 4756th TTS was located at Tyndall AFB, Florida to support the Fighter Weapons Center located there. ADC also supported overseas training at Johnson AB, Japan (6th TTS). From Johnson AB, B-57Es deployed to Clark AB, Philippines; Andersen AFB, Guam, Naha AB, Okinawa and Itazuke AB, Misawa AB and Yokota AB, all in Japan for training of the interceptor squadrons assigned to those bases. The 6th TTS was inactivated by late 1957 and the Canberra trainers were designated a flight of the 8th Bombardment Squadron at Johnson AB. In Europe, USAFE supported a squadron of B-57E gunnery trainers at Wheelus AB, Libya where European-based interceptors deployed for "live firing" over the vast desert range there.
