U.S. Army To Spend $2.2B On Nuclear Microreactors At Military Bases
The Janus program aims to give bases resilient power as reactors run for years without refueling and the Army expects more than 20 to be built.
- On Wednesday, the U.S. Army awarded up to $2.2 billion to five companies to deploy nuclear microreactors at five military bases under its Janus Program, securing energy independence for installations.
- Part of the Janus Program unveiled last year, the military seeks to deploy portable reactors that provide resilient power if commercial grids fail or face cyberattacks affecting critical operations.
- Five vendors including Radiant Industries and Antares Nuclear will install units at Fort Bragg, Fort Campbell, Fort Hood, Fort Benning, and Fort Drum, with capacity ranging from 1 to 20 megawatts per reactor.
- Factory-Built facilities can power up within 48 hours of arrival at bases. Jeff Waksman, principal deputy assistant secretary of the Army for installations, energy and environment, emphasized the reactors' rapid deployment capability.
- While the Army will license the reactors, officials intend for the technology to transition to the commercial market later. The Army is coordinating with the Energy Department to remove radioactive waste with no long-term storage on-site.

U.S. Army To Spend $2.2B On Nuclear Microreactors At Military Bases
Back in October 2025, the U.S. Army unveiled the Janus Program to supply portable nuclear microreactors to military bases by 2028. Whereas these reactors are much smaller than conventional nuclear plants, they typically generate 1-20 megawatts of electricity per reactor, significantly more than what the biggest portable generators can manage. That makes them ideal for the military, considering that major military bases consume as much power as a…
