WASHINGTON — The Department of the Army is announcing today that the Janus Program has selected five nuclear energy vendors, and five initial locations.
In partnership with the Department of War Innovation Unit (DIU), the Army is awarding up to a combined $2.2 billion to own, construct, and operate nuclear microreactors on military installations. These vendors will deliver safe, secure, and reliable nuclear power, strengthening the Army’s ability to project power globally, while supporting the revitalization of American industrial capacity and technological leadership. With the private sector funding expected along with these government dollars, the Army expects more than 20 total nuclear microreactors will be built and operated across Department of War installations.
The five selected vendors and installations are as follows:
Antares Nuclear, Inc. – Fort Bragg, North Carolina
BWXT Advanced Technologies, LLC – Fort Campbell, Kentucky
General Atomics Electromagnetic Systems – Fort Hood, Texas
Radiant Industries, Inc. – Fort Benning, Georgia
Westinghouse Government Services – Fort Drum, New York
“Since launching the Janus Program, our mandate from President Trump and Secretary Hegseth has been clear: secure the power our warfighters need to train, deploy and win,” said Dan Driscoll, Secretary of the Army. “Awarding these contracts accelerates our ability to deliver safe, reliable baseload power directly to our installations. We are building the energy resilience necessary to project combat power globally, without relying on potentially vulnerable external grids.”
“The Janus Program is grabbing the baton from Project Pele and the [Department of Energy’s] Reactor Pilot Program,” said Dr. Jeff Waksman, principal deputy assistant secretary of the Army for Installations, Energy and Environment. “We are seeking not just reactors capable of turning on for a brief demonstration, but rather systems able to deliver power with high-capacity factors for years of operation. The Janus Program will be a complete success when and only when we have assisted multiple nuclear companies in developing truly reliable and affordable nuclear microreactors which they can sell to other buyers beyond just the military.”
After gathering technical and operational information from industry via an Area of Interest released by DIU, the Army down-selected potential industry awardees for negotiation of Other Transactions Authority-based agreements. A decision board and panel of top nuclear and technical experts from the Department of Energy, national laboratories and representatives across the services provided deeply rigorous input on the technical risks, financial situation, and management capabilities of the solutions. The close collaboration with technical experts and service representatives ensured selected vendors would provide solutions to enhance energy resilience for specific operational needs at military installations.
“When DOE created an authorization pathway for the demonstration of advanced reactor designs, we quickly began to realize how valuable these technologies could be for fortifying our national defense infrastructure,” said Assistant Secretary of Nuclear Energy Ted Garrish. “We are honored to work in lockstep with the Army to leverage nuclear energy innovation in support of our country’s military operations at home and abroad.”
The alignment of these vendors with Army installations represents the culmination of a year-long effort to evaluate and prioritize installations based on a multitude of factors from energy needs to seismic and hydrological considerations, all with a primary focus on safety. As the Janus Program moves forward, it is intended that these vendors will also site nuclear technologies on other service installations for continued energy resilience across the entire DOW. Additional Army and other Service sites will be announced at a later date. The Army continues to drive towards the September 2028 target outlined in President Trump’s Executive Order 14299 for operation of a first reactor, regulated by the Army, on a military installation.
“The Army is leading the nation in its return to nuclear preeminence via the Janus Program,” said Jason Craft, Janus Program manager. “Our selected industry awardees represent the most viable technologies to achieve this capability, setting conditions for both installation energy resilience and operational energy solutions.”
Using a milestone-based payment model, vendors will receive government funding only after successfully hitting specific technical goals. This investment model brings together approximately $2.2 billion across FY2027-2031 along with significant capital investment from each vendor. This technology development model will speed up the delivery of next-generation energy solutions to the warfighter and promote innovation while ensuring accountability. The prototype reactors will be contractor-owned and operated.
“We need more power. We need it delivered faster and cheaper, and we need it to be more reliable,” said Owen West, director, DIU. “With Janus, DIU is assisting the Army’s micro reactor build — speeding military energy production to protect the nation.”
Collaboration with utility providers is essential to the success of Army’s nuclear power strategy and the Janus Program. The Army will work closely with serving utilities and privatized utility providers on the Janus Program to ensure the best possible outcomes. The Army also invites continued collaboration with utilities both now and in the future on utility-scale, grid-facing power generation opportunities sited on Army installations.
“The Army’s Janus Program has my full support, said Emil Michael, the War Department’s Chief Technology Officer. “The War Department is acting swiftly to implement President Trump’s Executive Order, Deploying Advanced Nuclear Reactor Technologies for National Security, to deploy a nuclear reactor on a military installation by September 2028. We are unleashing America’s domestic nuclear industrial base to ensure a more resilient and secure energy supply for the joint force.”
Reliable energy underpins national defense. The down-selection to these five vendors represents a critical step forward in securing the operational readiness of our forces. The Army is committed to fortifying the defense and strength of the nation now and for future generations.
