The U.S. Army said that it is launching a program to deploy nuclear reactors at bases across the country to support defense installations and missions. The plan, called the Janus Program, aims to deliver “resilient, secure, and assured energy.”
“The U.S. Army is leading the way on fielding innovative and disruptive technology,” Secretary of the Army Dan Driscoll announced. “We are shredding red tape and incubating next-generation capabilities in a variety of critical sectors, including nuclear power.”
“Since the Manhattan Project, the Department of Energy and the Department of War have forged one of the defining partnerships in American history—advancing the science, engineering, and industrial capability that power our national security,” explained Energy Secretary Chris Wright. “What began as a wartime effort became the backbone of America’s peacetime strength. Under President Trump’s leadership, we’re extending that legacy through initiatives like the Janus Program, accelerating next-generation reactor deployment and strengthening the nuclear foundations of American energy and defense.”
The Janus Program will construct commercial microreactors through a milestone-based contracting model alongside the Defense Innovation Unit (DIU), the Army said. These reactors will be commercially owned and operated, while the Army will provide oversight and assistance by supporting the “full uranium fuel cycle and broader nuclear supply chain, ensuring the program strengthens both defense and U.S. industrial capabilities.”
The program aligns with President Trump’s executive order, “Deploying Advanced Nuclear Reactor Technologies for National Security.” The order declared that the Trump administration will “ensure the rapid development, deployment, and use of advanced nuclear technologies to support national security objectives, such as the protection and operation of critical infrastructure, critical defense facilities, and other mission capability resources.”
