The U.S. Army, together with the Defense Innovation Unit (DIU), has reportedly signed agreements worth up to $2.2 billion to build nuclear microreactors at five military bases under its Janus Program. Five companies are reported to build, own, and operate (BOO) microreactors at their respective assigned bases.
The selected companies and bases are reported to be Antares Nuclear at Fort Bragg, North Carolina; BWXT Advanced Technologies at Fort Campbell, Kentucky; General Atomics Electromagnetic Systems at Fort Hood, Texas; Radiant Industries at Fort Benning, Georgia; and Westinghouse Government Services at Fort Drum, New York. The specific reactor designs to be applied at each base have not been identified.
The agreements, worth up to $2.2 billion over five years, were announced on August 26, 2026. Funding is reported to be disbursed in stages contingent on achieving performance milestones. The Army is reported to aim for more than 20 microreactors to be built and operated across the Department of Defense, starting with these five bases.
The introduction of small nuclear microreactors to enhance the power self-sufficiency of military bases is reported to be part of the U.S. defense authorities’ broader nuclear power expansion policy.
Implications for Korea’s Industry
As the small modular reactor (SMR) and microreactor market expands, driven by both military and industrial demand, it is reported that relevant Korean companies would benefit from continued monitoring of U.S. Department of Defense procurement trends.
Whether each of the five companies achieves its performance milestones and the actual start of construction are cited as key points to watch.
