The Great Falls Air Defense Sector (GFADS) is an inactive United States Air Force organization. Its last assignment was with the Air Defense Command 29th Air Division, being stationed at Malmstrom Air Force Base, Montana. It was inactivated on 1 April 1966.


GFADS was established in March 1959 assuming control of former ADC Central Air Defense Force units with a mission to provide air defense of central Montana. The organization provided command and control over several aircraft and radar squadrons.

On 15 February 1960 the new Semi Automatic Ground Environment (SAGE) Direction Center (DC-20) became operational. 47°30′59″N 111°10′55″W / 47.51639°N 111.18194°W / 47.51639; -111.18194 (GFADS-SAGE DC-20) DC-20 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) 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 ADC reorganization and consolidation, the command being redesignated as the 28th Air Division.
