Designed as a penetrator and long-range escort fighter, the F-101 Voodoo first appeared in 1954. Based on the earlier XF-88, it had no actual F-101 prototype built. Later versions served as long-range interceptors and reconnaissance aircraft. Built by McDonnell Aircraft of St. Louis, Missouri, this aircraft was delivered to the Air Force on September 26, 1958. It was immediately modified to the JF-101B configuration for testing by McDonnell, then later modified first to F-101F and later TF-101F configurations while serving with several active units. Its last duty assignment was with the Air National Guard at Selfridge AFB in Michigan, and it was retired in May 1972. Its markings represent an F-101B assigned to the 4440th Air Defense Group at Langley AFB in Virginia.
