context_page_description: The 27th Air Division was a United States Air Force numbered air division and the geographic Air Defense Command region controlled by the 27th AD. Its last assignment was with Air Defense Command's Tenth Air Force, at Luke Air Force Base, Arizona. It was inactivated on 19 November 1969.
context_section_description: Activated as the 27 Air Division (Defense) on 7 September 1950, the unit was assigned to ADC for most of its existence, the division's initial air defense area was southern California and later southern Nevada (and a small portion of Arizona by 1953).
  The 4705th Defense Wing was a temporary unit that absorbed the 1st Fighter-Interceptor Wing's personnel and equipment five days after it was organized in early 1952 at Norton Air Force Base. These units included, for example, the 94th Fighter-Interceptor Squadron at George Air Force Base). The wing was discontinued and the 94th FIS reassigned directly to 27th Air Division, which had reorganized at Norton in February, one month later.
  In May 1958, the 27th AD directed a hostile intercept of a "declared unknown" aircraft (without proper IFF), but the "interceptor pilot remembered...that opening bomb bay doors was to be considered a hostile act only after declaration of an Air Defense Emergency or Warning Yellow or Red" (the SAC B-47 was on a Radar Bomb Scoring bomb run near the Los Angeles Bomb Plot.)  The 27th AD was designated 1 of 23 NORAD divisions effective 10 June 1958 by NORAD General Order 6.
