except for those under the control of its 32d Region, which controlled air defense in the Southeastern United States. Although the number of ADC interceptor squadrons remained almost constant in the early 1960s, attrition (and the fact that production lines closed in 1961) caused a gradual drop in the number of planes assigned to a squadron, from 24 to typically 18 by 1964. The force reduction continued, finally resulting in a reduction in the number of interceptor units, and the group was inactivated in the spring of 1966. Logistics support The group was redesignated the 327th Aircraft Sustainment Wing and activated in 2005 as part of the Air Force Materiel Command Transformation initiative that replaced traditional staff offices in the command's centers with wings, groups, and squadrons. The wing organized, directed and controlled total life-cycle management of 94 Boeing B-52 Stratofortress, 585 Boeing KC-135 Stratotankers and C-135s, 69 Rockwell B-1 Lancers and 416 contractor logistics (including tanker, trainer, telemetry, airlift, command & control and US Presidential aircraft) aircraft. Other supported systems included the Northrop Grumman B-2 Spirit, Boeing E-3 Sentry aircraft, Air Traffic Control and Landing Systems (TRACALS), and the worldwide High Frequency Global Communications System. The wing was also responsible for modification and upgrades to these systems. It was inactivated in 2010 and replaced by the Aerospace Sustainment Directorate of Oklahoma City Air Logistics Center when Materiel Command returned to its traditional organizational structure.
