Chicago Air Defense Sector

The Chicago Air Defense Sector (CADS) is an inactive United States Air Force organization. Its last assignment was with the Air Defense Command (ADC) 30th Air Division at Truax Field Wisconsin. It was inactivated on 1 April 1966.

History
CADS was established by redesignation of the never active 4628th Air Defense Wing at Truax Field, Wisconsin in March 1957 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. The organization provided command and control over one interceptor and several radar squadrons.

On 1 October 1959, the new Semi Automatic Ground Environment (SAGE) Direction Center (DC-07) and a Combat Center (CC-02) became operational. 43.12667°N, -89.335°W DC-07 was equipped with dual AN/FSQ-7 Computers. 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 as part of ADC reorganization and consolidation, the command being replaced at Truax Field by the 20th Air Division, and its units in Indiana were reassigned to the 34th Air Division.
