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

History

CADS was established in March 1957 at Truax Field, Wisconsin, assuming control of former ADC Central Air Defense Force units with a mission to provide air defense of Illinois; Indiana; most of Iowa and northern Missouri. The organization provided command and control over several aircraft and 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°07′36″N 089°20′06″W / 43.12667°N 89.335°W / 43.12667; -89.335 (CADS-SAGE DC-07, CC-02) DC-07 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 1 April 1966 as part of ADC reorganization and consolidation, the command being redesignated as the 20th Air Division; and its units in Indiana were reassigned to the 34th Air Division.
