As the nation honors those who have served, the U.S. Army is charting a new course in defense readiness through the Janus Program—a next-generation nuclear power initiative aimed at deploying small modular and microreactors across Army bases by 2028. The program embodies the same spirit of innovation and resilience that has long defined America’s armed forces, ensuring bases can operate independently from vulnerable civilian grids. Producing under 20 MW each, these reactors will deliver secure, carbon-free power to sustain critical missions under any condition—honoring the legacy of service through strengthened national defense.
Under the Janus framework, the Army is partnering with the Defense Innovation Unit (DIU) and the Department of Energy (DOE) in a milestone-driven contracting model inspired by NASA’s commercial space initiatives. The reactors will be commercially owned and operated, with the Army maintaining regulatory oversight and DOE contributing technical and fuel-cycle expertise. Building on earlier efforts like Project Pele, this approach is designed to de-risk first-of-a-kind technologies while stimulating domestic supply chains for advanced nuclear systems and HALEU (high-assay low-enriched uranium) fuel.
Initial deployment is planned for nine Army installations, potentially hosting up to two microreactors per site by 2027–2028. These compact, transportable units will feature factory-built modularity, extended refueling intervals, and simplified operations, providing unmatched energy assurance. While their capacity is small relative to traditional nuclear plants, their strategic value lies in protecting mission continuity—ensuring that no matter the challenge, from cyber threats to natural disasters, America’s forces remain powered and prepared.
The Janus Program could also serve as a national catalyst for advanced nuclear commercialization, proving out designs under demanding, real-world conditions. By anchoring early demand within the defense sector, the Army is creating a launchpad for broader civilian adoption—advancing U.S. leadership in both clean energy and security innovation. As we recognize the service of America’s veterans, the Janus initiative stands as a forward-looking tribute: ensuring the strength, independence, and resilience of the nation they have defended endures for generations to come.
