Pentagon nuclear reactor contracts: Three firms win micro‑reactor race for Air Force bases

The Pentagon’s latest move on its Advanced Nuclear Power for Installations programme centers on the Pentagon nuclear reactor contracts that will shape micro‑reactor deployment at two strategic bases.

Pentagon nuclear reactor contracts narrow to three contenders

After a competitive review of eight original vendors—BWXT, Oklo, X‑energy, Kairos Power, Radiant, General Atomics, Westinghouse and Antares—the Department of Defense announced a trio of winners: General Atomics, Westinghouse and BWXT. This cut represents a ↓ 5 reduction, focusing resources on proven designs.

Both Buckley Space Force Base in Colorado and Malmstrom Air Force Base in Montana are slated for micro‑reactor installation by ↑ 2030, accelerating the military’s push for resilient, off‑grid power.

“Deploying compact reactors on our installations will enhance mission readiness and reduce logistical footprints,” a senior Pentagon official told Reuters.

Industry analysts note that the selected firms collectively hold over 30 % of the U.S. nuclear services market, positioning them to capture future defense contracts.

Further details are expected in the upcoming fiscal year, as the ANPI programme seeks to transition prototypes into operational units.
