The San Francisco Air Defense Sector (SFADS) is an inactive United States Air Force organization. Its last assignment was with the 28th Air Division, being stationed at Beale Air Force Base, California.


SFADS was established in February 1959 assuming control of former ADC Western Air Defense Force units in California west of the Sierra Nevada; north of Santa Barbara and south of Eureka. The organization provided command and control over several aircraft and radar squadrons.

On 1 December 1960 the new Semi Automatic Ground Environment (SAGE) Direction Center (DC-18) became operational. Lua error in Module:Coordinates at line 668: callParserFunction: function "#coordinates" was not found. DC-18 was equipped with dual AN/FSQ-7 Computers. The day-to-day operations of the command was to train and maintain tactical flying units flying jet interceptor aircraft (F-94 Starfire; F-102 Delta Dagger; F-106 Delta Dart); ( 2 F-101B Voodoo Squadrons) in a state of readiness with training missions and series of exercises with SAC and other units simulating interceptions of incoming enemy aircraft.

The Sector was inactivated on 1 August 1963 as part of an ADC consolidation and reorganization; and its units were assigned to 28th Air Division at Hamilton AFB.
