History

Assigned to Air Defense Command (ADC) for most of its existence, the division's mission was the air defense of southern California in September 1950 and later southern Nevada. By 1953, its area of control included a small portion of Arizona. Inactivated in October 1959 at Norton AFB, and redesignated Los Angeles Air Defense Sector (LaADS)

Reactivated in January 1966 at Luke AFB, it gained responsibility for the air defense of southern California, southern Nevada, and all of Arizona by consolidation of the LaADS and Phoenix Air Defense Sectors. The 27th administered and trained subordinate units, and participated in numerous air defense training exercises. In addition, during the 1960s it supervised training of Air National Guard units with a pertinent mobilization assignment.
