missions from Davis–Monthan. Following the Cuban Missile Crisis in 1963, the 4080th Strategic Reconnaissance Wing at Laughlin AFB, Texas, relocated to the base and assumed responsibility for all U-2 operations, emphasizing long-range strategic reconnaissance and intelligence collection. As a Strategic Air Command (SAC) unit, the 4080th was later redesignated the 100th Strategic Reconnaissance Wing and also acquired Lockheed DC-130 Hercules aircraft for launch and control of Firebee reconnaissance drones that were the precursors of contemporary unmanned aerial systems. The DC-130s and U-2s remained at the Davis–Monthan until 1976, when the 100 SRW was inactivated, its DC-130s transferred to Tactical Air Command's 432d Tactical Drone Group, and its U-2s transferred to SAC's 9th Strategic Reconnaissance Wing (9 SRW) at Beale Air Force Base, California, where U-2 Dragon Lady operations were consolidated with SR-71 Blackbird operations. On 15 June 1964, Davis–Monthan's 303d Bombardment Wing was inactivated as part of the retirement of the B-47 Stratojet from active service. The year 1964 brought back the combat crew training mission of the World War II years with the 4453d Combat Crew Training Wing of the Tactical Air Command equipped with the Air Force's newest and most sophisticated fighter, the McDonnell Douglas F-4 Phantom II. In July 1971, the 355th Tactical Fighter Wing, flying the A-7 Corsair II aircraft, was activated at the base and the previously assigned F-4s were moved to Luke AFB, near Phoenix, Arizona. Tactical Air Command On 1 October 1976, the base was transferred to Tactical Air Command (TAC) after 30 years under SAC, with SAC's 390th Strategic Missile Wing becoming a tenant command of the base. It was also that year the 355th Tactical Fighter Wing accepted the first A-10 Thunderbolt II. Since 1979, D–M has been the training location for pilots in the A-10; the base was redesignated the 355th Tactical Training Wing on 1 September 1979. The organization was later redesignated the 355th Fighter Wing since it includes operational, deployable A-10 squadrons in addition to its CONUS training mission The 1980s brought several diverse missions to D–M. The headquarters charged with overseeing them was now the 836th Air Division, which was activated 1 January 1981. The AD advised Air Force component commanders and land forces on A-10 aircraft tactics, training, employment and readiness, and subordinate units participated in exercises such as Red Flag and Celtic Echo.
