The 4706th Air Defense Wing is a discontinued United States Air Force (USAF) organization. Its last assignment was with the 37th Air Division of Air Defense Command (ADC) at O'Hare International Airport (IAP), Illinois where it was discontinued in 1956. It was established in 1952 at O'Hare as the 4706th Defense Wing in a general reorganization of Air Defense Command (ADC), which replaced wings responsible for a base with wings responsible for a geographical area. It assumed control of several Fighter Interceptor squadrons that had been assigned to the 142d Fighter-Interceptor Wing, an Air National Guard wing mobilized for the Korean War and the 56th Fighter-Interceptor Group. In early 1953 it also was assigned six radar squadrons in the Midwest and its dispersed fighter squadrons combined
