As a result of the 2005 Base Realignment and Closure (BRAC), key elements of the Air National Guard Headquarters (ANG HQ) currently operating in leased space in Crystal City, Virginia, will be relocated to a new facility at Andrews Air Force Base, Maryland. The new Headquarters and Readiness Center Building (Building 3501) will be an approximately 170,000 sq ft addition to the existing Building 3500 (Conaway Hall) in the northeast portion of Andrews AFB.
