Its last assignment was with Air Defense Tactical Air Command, assigned to First Air Force, being stationed at March Air Force Base, California. It was inactivated on 30 September 1990. History Was established in October 1948 by Air Defense Command (ADC) as intermediate level of command. Initially responsible for atmospheric air defense of middle Atlantic region from North Carolina to greater New York City area east of the Appalachian mountains. Commanded Manual Direction Center (MDC) at Roslyn Air Force Station, New York (P-3) 1948–1958 directing interceptor units to aircraft identified by Aircraft Control and Warning Squadrons at radar stations in AOR. It employed off shore naval picket ships, fixed "Texas Tower" radar sites, airborne early warning units, and a civilian Ground Observer Corps program. The latter phased down when the SAGE program was implemented. Improved radar and communications equipment and fighter interceptors, and better techniques and methods, eventually led to the 26th Air Division becoming the first operational Semi Automatic Ground Environment SAGE Direction Center (DC-1) within Air Defense Command at McGuire Air Force Base, New Jersey.
