CADS was established by redesignation of the never active 4628th Air Defense Wing at Truax Field, Wisconsin in March 1957[1] with a mission to provide air defense of Illinois, Indiana, most of Iowa and northern Missouri, but did not assume control of former ADC Central Air Defense Force units until 1959.

[2] The organization provided command and control over one interceptor and several radar squadrons.

The day-to-day operations of the command were to train and maintain tactical flying units flying jet interceptor aircraft (F-102 Delta Dagger, F-106 Delta Dart) and radar squadrons 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 inactivated 1 April 1966[1] as part of ADC reorganization and consolidation, the command being replaced at Truax Field by the 20th Air Division,[3] and its units in Indiana were reassigned to the 34th Air Division.
