4520th Combat Crew Training Wing

• Specialized Role: The 4520th Combat Crew Training Wing (CCTW) was specifically established to provide advanced combat crew training, primarily focusing on the F-111 Aardvark, one of the most advanced tactical fighter-bombers of its time. • Location: The unit was based at Nellis Air Force Base, Nevada, a premier location for advanced air combat training and home to the USAF Weapons School. • Formation Year: The wing was activated in 1968 during the height of the Cold War, reflecting the USAF’s emphasis on technological advancement and readiness. • F-111 Training: The 4520th was among the first units to train aircrews on the General Dynamics F-111, a revolutionary aircraft known for its variable-sweep wings and terrain-following radar. • Transition to Tactical Air Command: The wing operated under Tactical Air Command (TAC), signifying its integral role in preparing crews for tactical bombing and strike missions. • Short-lived Designation: The 4520th designation was relatively short-lived; in 1973, it was replaced by the 474th Tactical Fighter Wing as part of an Air Force-wide reorganization. • Legacy in Training: The training programs and curriculum developed by the 4520th laid the foundation for future USAF tactical fighter crew training. • Operational Readiness: Crews trained by the 4520th were considered among the most proficient in low-level penetration and night/all-weather bombing operations. • Contribution to Vietnam War: Many aircrews trained by the 4520th went on to serve in the Vietnam War, where F-111s played a vital role in deep strike missions. • Distinctive Patch: The unit’s patch featured the F-111 in flight, symbolizing its pioneering role in introducing this advanced aircraft to operational service.
