The installation

The Army's Largest Armored Post

Fort Hood covers about 218,000 acres across Bell and Coryell counties near Killeen, halfway between Austin and Waco. It is the largest active-duty armored installation in the US, with about 60,000 direct employees including 38,642 active-duty soldiers, and the Texas Comptroller put its contribution to the state economy at $39B in 2023.

Camp Hood opened in September 1942 as the Tank Destroyer Tactical and Firing Center, sited for maneuver space no eastern site could match. The post was renamed Fort Cavazos in May 2023 and returned to Fort Hood in June 2025, now honoring Col. Robert B. Hood.

    Contracts into the force; III Armored Corps and 1st Cavalry Division use the systems

The Operational Test Command makes Fort Hood the gate for new platforms entering the Army. Lockheed Martin, Northrop Grumman, Leidos and Booz Allen Hamilton run autonomy, drone swarm and tactical AI programs on the post. The Austin companies seeded around Capital Factory now send their systems 60 miles up I-35 to be tested against active-duty armored units.

One kill chain

The Ground Half of the Orbital Layer

Each of these systems carries its own AI compute for jammed, GPS-denied fights. Connected, they use the same orbital network Golden Dome is building: SpaceX Starshield and its $2.29B data network, the Space Development Agency's tracking constellation and commercial Starlink. Palantir and Anduril software in Austin ties the orbital picture to the system on the ground; Fort Hood is where the ground half is proven. See the Golden Dome Texas Corridor.

Workforce

Soldiers Into the Texas Industrial Base

About 5,000 to 7,000 soldiers leave active duty at Fort Hood each year, a trained workforce for SpaceX McGregor 60 miles north, the Austin-Taylor chip plants and the DFW defense base. Programs such as Heroes MAKE America connect them to Texas manufacturers.

Killeen, Copperas Cove and Harker Heights rise and fall with deployment cycles, and intergovernmental agreements with the post cover transit, roads, water, wastewater and emergency management.
