the Vietnam War, becoming a squadron to train Military Assistance Program (MAP) pilots from over 20 nations on the F-5. It was discontinued in 1989 and the 425th was inactivated. In the summer of 1971, the 58th TFTW received F-4C Phantom IIs, and the wing assumed the F-4 pilot training role that was formerly done by the 4453d CCTW at Davis-Monthan, when that base was converted to an operational A-7D base by the arrival of the 355th TFW from Takhli RTAFB, Thailand. F-15 Eagle era In November 1974, the Air Force's newest air superiority fighter, the F-15 Eagle, came to Luke. To accommodate the F-15, the 555th Tactical Fighter Training Squadron was activated. The early F-15As, however, were quite troublesome, with engine problems limiting their effectiveness and also their availability. It was not until June 1976 that a second F-15 training squadron was established, with the 4461st Tactical Fighter Training Squadron standing up on 23 June. The assets of the 4461st TFTS were re-designated as: 461st Tactical Fighter Training Squadron: 1 July 1977. The 550th TFTS traded in its F-4s in August 1977 becoming the third F-15 training squadron. The F-15As, which remained troublesome throughout the 1970s, were replaced in 1982 with the updated F-15D. On 25 August 1979, the 405th Tactical Training Wing was activated at Luke by Tactical Air Command to consolidate the F-15 Eagle Replacement Training Unit (RTU) operations. It took over the 425th, 461st 550th and 555th Tactical Fighter Training Squadrons The 426th Tactical Fighter Training Squadron converted from F-4 Phantom II to F-15 training in January 1981 specifically to support the TAC Air Defense Command (ADTAC) training mission inherited from the inactivated Aerospace Defense Command which was merged into TAC. On 19 November 1990, the 555th TFTS changed its course from air superiority combat training with the Eagle to air defense interceptor training with the F-15C/D when TAC began assigning F-15s to interceptor duty, the 426th being inactivated. The 461st TFTS received its first F-15E Strike Eagle in July 1988, and the 550th TFTS became the second F-15E training squadron in March 1989. On 1 October 1991, due to the implementation of the Objective Wing at Luke and the "One base, one wing" policy, the 405th TTW was shut down and the F-15s were reassigned back to the 58th TTW. In 1993, 1st Lt Jeannie M. Flynn became the first woman to complete training in
