The Sioux City Air Defense Sector (SCADS) is an inactive United States Air Force organization. Its last assignment was with the Air Defense Command 29th Air Division, being stationed at Sioux City Air Force Station, Iowa.
SCADS was established in October 1958 assuming control of former ADC Central Air Defense Force units in western Iowa, most of Nebraska along with southern South Dakota. Also provided air defense over parts of Minnesota, Colorado and Wyoming. The organization provided command and control over several aircraft and radar squadrons.
On 1 December 1961, the new Semi Automatic Ground Environment (SAGE) Direction Center (DC-22) became operational. DC-22 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 on 1 April 1966 as part of an ADC consolidation and reorganization; and its units were reassigned to the 30th Air Division.
