Joint Base Anacostia-Bolling, District of Columbia

What used to be Bolling Air Force Base is now merged with Naval Support Facility Anacostia to become Joint Base Anacostia-Bolling. It originally served as a defensive air base for the nation’s capital, but now its runways have been developed, enabling only helicopters to land there, which they do with some frequency, as this is one of the principal bases used by Marine One, the fleet of helicopters used by the President. The Secret Service has major facilities at the base, as does the White House Communications Agency, and the Defense Intelligence Agency. The Marines have a well-stocked reserve base on site too.
