4711th Air Defense Wing

The 4711th Air Defense Wing is a discontinued United States Air Force organization. Its last assignment was with the 30th Air Division of Air Defense Command (ADC) at Selfridge Air Force Base, Michigan, where it was discontinued in 1956. It was established in 1952 at Presque Isle Air Force Base, Maine as the 4711th Defense Wing in a general reorganization of ADC, which replaced wings responsible for a base with wings responsible for a geographical area.

History
The wing was organized as the 4711th Defense Wing at the beginning of February 1952 at Presque Isle Air Force Base, Maine as part of a major reorganization of ADC responding to ADC's difficulty under the existing wing base organizational structure in deploying fighter squadrons to best advantage. The wing assumed operational control and the air defense mission of fighter squadrons formerly assigned to the inactivating 23d Fighter-Interceptor Wing. The 74th and 75th Fighter-Interceptor Squadrons, flying North American F-86 Sabre aircraft were at Presque Isle, while the 101st Fighter-Interceptor Wing's 132d Fighter-Interceptor Squadron, flying Lockheed F-80 Shooting Stars was at Dow Air Force Base, Maine, and the 134th Fighter-Interceptor Squadron, flying World War II era North American F-51 Mustangs The two dispersed squadrons were federalized Air National Guard (ANG) squadrons that had been attached to the 23rd Wing. was transferred to the wing from direct assignment to Eastern Air Defense Force. The support elements of the 23rd Wing's 23rd Air Base Group and 23rd Maintenance & Supply Group were replaced at Presque Isle by an air base squadron and air base squadrons were activated at Presque Isle and Burlington to support the fighter squadrons at those bases. The wing's mission was to train and maintain tactical units in a state of readiness to intercept and destroy enemy aircraft attempting to penetrate the air defense system in the Northeastern United States. In June, the 74th converted to Northrop F-89 Scorpion interceptor aircraft, but by fall its F-89Cs had been grounded and the squadron was forced to convert to Lockheed F-94 Starfires. In February 1953, another major reorganization of ADC activated air defense groups at ADC bases with dispersed fighter squadrons. Two groups were assigned to the wing and assumed direct control of the fighter squadrons, as well as support squadrons to carry out their role as the USAF host organizations at their bases. As a result of this reorganization, the 528th Air Defense Group activated at Presque Isle and assumed control of the fighter squadrons there, while the 517th Air Defense Group activated to command the squadron at Ethan Allen AFB. The reorganization also resulted in the wing adding the radar detection, control and warning mission, and it was assigned six aircraft control & warning squadrons (AC&W Sq) to perform this mission. The 49th FIS traded in its F-80s for F-86s in the same month. Meanwhile, the 75th FIS moved to Suffolk County Air Force Base in October and was reassigned to another wing. As a result of Project Arrow, the 23d Fighter Group (Air Defense), replaced the 528th Air Defense Group at Presque Isle, while the 14th Fighter Group replaced the 517th Air Defense Group at Ethan Allen. In October, a second F-89 squadron, the 465th Fighter-Interceptor Squadron, activated at Griffiss. In preparation for the implementation of the Semi-Automatic Ground Environment air defense system, the 4711th Wing lost its operational units in March 1956 and moved to Selfridge Air Force Base, where it was discontinued shortly thereafter. ==Lineage==
