Originally known as Camp A. A. Humphreys during the start of World War One, it became known as Fort Belvoir in the 1930s to honor the Belvoir estate. The army base was the original home of the Army Engineer School before it was moved to Fort Leonard Wood. The United States Army Engineer Research and Development Laboratory was also stationed here at one point. Today, the Department of Defense has many operations that are headquartered at Fort Belvoir. In fact, the future looks bright for this army installation as more plans for expansion and modernization are on the horizon.
Some of the agencies at Fort Belvoir include the Defense Logistics Agency, the Defense Acquisition University, the Defense Technical Information Center, the Defense Contract Audit Agency, the United States Army Intelligence and Security Command, and the Defense Threat Reduction Agency to name some of them. More are planning to move their operations to Fort Belvoir. The 249th Engineer Battalion (Prime Power) and the United States Army Prime Power School are both housed at Fort Belvoir along with the many agencies from the DoD and other military branches including the Air Force and Marines.
