Joint Base Anacostia–Bolling is a 905-acre (366 ha) military installation, located in Southeast, Washington, D.C., established on 1 October 2010 in accordance with congressional legislation implementing the recommendations of the 2005 Base Realignment and Closure Commission. The legislation ordered the consolidation of Naval Support Facility Anacostia (NSF) and Bolling Air Force Base (BAFB), which were adjoining, but separate military installations, into a single joint base, one of twelve formed in the country as a result of the law. The only aeronautical facility at the base is a 100-by-100-foot (30 by 30 m) helipad (ICAO: KBOF).
