The sector 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 controlled several aircraft and radar squadrons.

On 1 December 1960 the new Semi Automatic Ground Environment (SAGE) Direction Center (DC-18) became operational. 39°06′35″N 121°23′49″W 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 83d Fighter-Interceptor Squadron and 84th Fighter-Interceptor Squadron at Hamilton AFB, Ca., both were part of the sector's forces, under the command of the 78th Fighter Wing.

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 Air Force Base, California.
