America's Largest Military Bases

Naval Support Activity Crane Naval Base, or NSA Crane, was named after William M. Crane, a Navy officer who fought and died in the War of 1812. Nearly all of the base’s 62,435 acres are owned by the DoD and operated by the Navy.

The Naval Weapons Training Facility Boardman is a nearly 63,000-acre in area in Oregon, just south of the Columbia River. The area is primarily used for training with low and fast-flying attack aircraft.

Fort Chaffee Joint Maneuver Training Center is operated by the National Guard but is also used by a number of other local, state, and federal agencies. The base’s training functions include live-fire exercises, river crossing, and urban combat.

At Camp Gruber training facility, which was established in 1942 after the United States entered World War II, soldiers train in MOUT exercises (military operations on urban terrain) that replicate urban scenarios, such as collapsed buildings.

Fort Leonard Wood is home to three Army schools: U.S. Army Engineer; Chemical, Biological, Radiological, and Nuclear; and Military Police.
