On 5 January 2005 the Air Force reactivated the Air Force District of Washington (AFDW) as the single Air Force voice for planning and implementing Air Force and joint solutions within the National Capital Region (NCR). This event brought with it significant changes at Andrews. On 12 May 2006, the 89th Medical Group at Andrews and the 11th Medical Group, Bolling Air Force Base, Washington, D.C. combined into the 79th Medical Wing where it established its headquarters at Andrews. In June 2006, the 316th Wing stood up under the command of AFDW as the new host unit for Andrews Air Force Base and its nearly 50 tenant units to include organizations from the U.S. Army, the Air Force Reserve Command, Air National Guard, Navy Reserve, Marine Corps Reserve and the Civil Air Patrol. The activation of the 316th prompted the transfer of the 1st Helicopter Squadron from the 89th Airlift Wing to the 316th Operations Group. In May 2007 the AFDW, as well as the 844th Communications Group, transferred from Bolling AFB to Andrews AFB.
