The Air Defense Command 64th Fighter-Interceptor Squadron was deployed from the 25th Air Division at Paine Field, Washington to Clark AB and assigned to the 405th on 10 June 1966 to supplement the F-102 mission in Southeast Asia as well as provide air defense for the Philippines. F-102s stood rotational alert at TDYs Bien Hoa and Da Nang Air Bases in South Vietnam and at Udorn and Don Muang Air Bases in Thailand. The F-102A was finally withdrawn from Southeast Asia in December 1969 with the phaseout of the aircraft from the USAF inventory, also the clear lack of need for a dedicated air defense interceptor over South Vietnam. The F-102A established an excellent safety record during its duty in Vietnam. In almost seven years of flying air defense and a few combat air patrols for SAC B-52s, only 15 F-102As were lost.
