However, the air defense area in New Mexico for the 81st Fighter-Interceptor Wing lasted only a short while. In May 1950, the 81st Fighter-Interceptor Wing departed for Moses Lake AFB, Washington, along with the 91st and 92d FIS, which were under its jurisdiction. The 93d Fighter-Interceptor Squadron took the 81st Fighter-Interceptor Wing's place at Kirtland and was attached to the Albuquerque Air Defense Sector in the same month. The 93d FIS employed the F-86A Sabre jet, the USAF's first swept-wing jet designed as a high-altitude day fighter, was on ready alert, and was continually training to increase its combat efficiency.
