in August 1946 as part of Eleventh Air Force (later Alaskan Air Command) as part of the air defense forces in the northwest Pacific. Squadron began training new P-51 pilots at Ladd Field, Alaska. Later, it was equipped with F-80Bs in March–April 1948, F-80Cs in October–December 1948, F-94Bs in the summer of 1951, and F-89Cs in September 1953. With these aircraft, the squadron provided fighter aircraft defense in support of the Alaska Area until late in the 1950s. In October 1969, the 65th Fighter Weapons Squadron took over the F-100D/F Super Sabre aircraft, personnel, and facilities of the 4536th Fighter Weapons Squadron at Nellis Air Force Base. F-100s tail coded "WB", only to become non-operational early in 1970. On reactivation was equipped with A-7D Corsair II ground attack aircraft, operating from Luke Air Force Base, Arizona and Davis-Monthan Air Force Base, Arizona. Conducted fighter weapons training with the A-7D until June 1975 when aircraft sent to Air National Guard units. Aggressor training The squadron was re-equipped in October 1975 with F-5E Tiger IIs, the aircraft having been originally destined for delivery to South Vietnam until that nation collapsed earlier that year and the aircraft subsequently becoming available. Since the F-5E had approximately the size and performance characteristics of a Soviet MiG-21, it was used throughout the US and overseas to teach adversarial tactics and provide dissimilar air combat training to US Air Force flying units, eventually becoming the 65th Aggressor Squadron. The squadron's F-5s carried no tail codes, although they did carry the Nellis black/yellow checkertail stripe and a Tactical Air Command emblem on tail. The aircraft were painted in Soviet Air Forces motif with subdued USAF markings, with the last two digits of the F-5's tail number painted in the then-Soviet style in red on the front fuselage, highlighted in white. Deployed throughout US and overseas to teach adversarial tactics and provide dissimilar air combat training to US Air Force flying units. Re-designated 65th Tactical Fighter Aggressor Squadron on 30 December 1981. Added subdued "WA" tail code in early 1987. Redesignated again as 64th Aggressor Squadron on 4 January 1983. Operated until 1989 when the F-5s began having structural problems with the airframes. As the Cold War ended and military budgets adjusted, the unit flew their last aggressor flight in the F-5 on 7 April 1989. Return to aggressor training The squadron was reactivated in September 2005, flying F-15Cs
