Army Moves Forward with Project to Place Nuclear Microreactors on Installations
Project Janus aims to deploy microreactors at 10 U.S. Army bases by 2028 to reduce diesel use and enhance energy independence, officials said.
- On Tuesday, Army Secretary Dan Driscoll and Energy Secretary Chris Wright announced the Janus Program to place commercial nuclear microreactors on U.S. Army bases to generate power without relying on diesel fuel.
- Earlier this year, a presidential executive order directed the Department of War to operate an Army-regulated nuclear reactor by September 2028, citing energy demands from artificial intelligence and new-age weaponry plus supply chains risks.
- Technical details show that microreactors are 100 to 1,000 times smaller than conventional reactors, transportable by tractor-trailer or C-17 transport aircraft, producing up to 50 megawatts off-grid; Idaho National Laboratory expects the first to go critical before July 4, 2026.
- The Army will hold a competition to supply two microreactors for up to nine bases, involving local communities, and will not place reactors where objections exist.
- The initiative positions the U.S. nuclear industry to grow rapidly over 10 to 15 years as microreactors replace diesel generators at forward-deployed bases, enhancing operational independence and logistics.

Army to build commercial nuclear microreactors for resilient domestic installation energy
The Army is teaming up with the Energy Department and Defense Innovation Unit to launch its latest nuclear reactor program aimed at putting fully operational commercial microreactors on domestic military installations to support energy resilience for the warfighter, service officials announced today. The initiative -- dubbed the Janus Program -- is the service’s “first big step toward having the United States Army work with the private sector, w…
Army Launches Nuclear Power Program
A new nuclear power program will deliver resilient, secure, and assured energy to support national defense installations and critical missions, the Department of the Army announced Tuesday. The Army celebrated the launch of the Janus Program, which will leverage its nuclear regulatory authorities in close partnership with the Department of Energy to ensure the highest standards of safety, oversight, and transparency. "The U.S. Army is leading th…
