Learn More About Fort Belvoir
Today, Fort Belvoir is the largest employer in Fairfax County with twice as many employees as The Pentagon. It has focused enormous effort and resources into preserving the natural beauty and wildlife that surrounds the base.

The base is comprised of three geographic areas: the main base, Davidson Army Airfield, and the Fort Belvoir North Area. The mission of Fort Belvoir is to be a “strategic sustaining base for America’s Army” and the base houses a dozen major Army commands, nineteen different Department of the Army agencies and 26 Department of Defense agencies. Fort Belvoir Community Hospital and its two satellite clinics in Fairfax and Dumfries provides stellar patient care. The U.S. Army Cyber Command (ARCYBER), Intelligence and Security Command (INSCOM), and Defense Threat Reduction Agency (DTRA) also call Fort Belvoir home. Basically, if a unit or agency has anything to do with our Nation’s defense, it at least has representation on Fort Belvoir.
