The Army has selected nine sites for consideration as it looks to place microreactor power plants on its installations.

Known as the Janus Program, the initiative is the Army’s next-generation nuclear power program and seeks to develop and install microreactor power plants in line with a presidential executive order issued in May 2025 to “deliver secure, resilient and reliable energy to support national defense installations and critical missions,” according to an Army news release.

In partnership with the Defense Innovation Unit, the program will build commercial microreactors through a milestone-based contracting model to accelerate advanced energy solutions to the warfighters, the release says.

After thorough analysis and on-site assessments, the Army named nine sites for potential initial deployment of microreactors. They are Fort Benning, Georgia; Fort Bragg, North Carolina; Fort Campbell, Kentucky; Fort Drum, New York; Fort Hood, Texas; Fort Wainwright, Alaska; Houston Army Ammunition Plant; Joint Base Lewis-McChord, Washington; and Redstone Arsenal, Alabama.

The sites were selected based on mission, energy requirements and resiliency gaps, power infrastructure, and environmental and technical considerations, according to the release. Timelines for development of the microreactor power plants will be announced as “teams cooperate with military installations, residents and surrounding communities,” and the Army is committed to a transparent process, the release said.

The Army also said the final number and location of microreactors will be determined as part of the acquisition process.

The rollout of Janus technology will occur in stages as the Army validates lessons learned and ensures safe, efficient implementation, according to the release, which explained that the projects will be self-contained, protected appropriately and comply with applicable federal, state, and local regulations, leveraging the safety features inherent in next-generation reactor designs.

“These early site selections align with the Department of War’s goal of accelerating the pace of deploying on-site nuclear generation at our installations,” Jordan Gillis, assistant secretary of the Army for installations, energy and environment, said in the release. “Through the use of the Army’s unique nuclear regulatory authorities, we are deploying a resilient, secure and reliable energy supply for critical defense operations and in support of the most lethal land-based fighting force in the world.”

The Janus Program is leveraging the Department of Energy and its network of National Labs to ensure the appropriate expertise is applied to the evaluation of proposed designs, operational plans and emergency preparedness plans, according to the release.

The Army does not anticipate any significant impact to installation land use, the release says.
