This was the 133rd F-106 produced by Convair at San Diego in 1959 and flew with five different Fighter Interceptor Squadrons before reaching the 194th FIS at Fresno in 1974. Ten years later it went in storage at DM AFB but emerged in 1991 for conversion to a QF-106 drone, becoming Tyndall-based. It returned to DM in 1998 but was selected for preservation in the Aerospace Museum at Hill AFB, UT, where it has undergone a superb restoration for display in the marks of its first unit, the 456th FIS (Castle)
