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 the 28th and 29th Air Divisions.

The SAGE radar stations of Air Defense Command were the military installations operated by USAF squadrons using the 1st automated air defense environment and networked by the SAGE System, a computer network. Most of the radar stations used the Burroughs AN/FST-2 Coordinate Data Transmitting Set (CDTS) to automate the operator environment and provide radar tracks to sector command posts at SAGE Direction Centers (DCs), e.g., the Malmstrom Z-124 radar station was co-located with DC-20. The sector/division radar stations were networked by DCs and Manual Control Centers to provide command, control, and coordination for ground-controlled interception of enemy aircraft by interceptors such as the F-106 developed to work with the SAGE System.
The 913th Aircraft Control and Warning Squadron is an inactive United States Air Force unit. It was last assigned to the Sault Sainte Marie Air Defense Sector, Air Defense Command, stationed at Pagwa Air Station, Ontario, Canada. It was inactivated on 1 June 1963.
