WaADS was established in December 1956 as the 4625th Air Defense Wing.[1] It was not assigned any units until 1958 when it assumed control of former ADC radar squadrons.

On 1 February 1959 the new Semi Automatic Ground Environment (SAGE) Direction Center (DC-04) became operational. DC-04 was equipped with dual AN/FSQ-7 Computers. The day-to-day operations of the command were to train and maintain tactical units flying jet interceptor aircraft (F-101 Voodoo; F-102 Delta Dagger; F-106 Delta Dart) or interceptor missiles (CIM-10 Bomarc) in a state of readiness with training missions and series of exercises with Strategic Air Command and other units simulating interceptions of incoming enemy aircraft.

The sector was eliminated on 1 April 1966 due to a general reorganization of Air Defense Command, most of its assigned units being reassigned to the 33d Air Division
