PADS was established in June 1958 assuming control of former ADC Western Air Defense Force units in eastern Oregon and northwest California.

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) 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 April 1966 as part of an ADC consolidation and reorganization; and its units were reassigned to 28th Air Division.

The 689th Radar Squadron (SAGE) was moved to DC-12, 25th Air Division, McChord AFB, WA, on 1 April 1966.
