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 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.
