OCTOBER 21, 2026 – The Department of the Navy announces the selection of Radiant Industries, Inc. (Radiant) to design, build, and deliver a prototype Microreactor Power Plant (MPP). The selection of Radiant’s Kaleidos microreactor design, pursued in conjunction with the Department of the Army’s Janus Program, marks a milestone in securing reliable, grid-independent, and dispatchable power for critical military infrastructure at Naval Weapons Station (NWS) Crane, Indiana.
“The industrial and operational testing missions executed at NWS Crane are vital to the readiness of our fleet and the future fight,” said Brendan Rogers, Assistant Secretary of the Navy for Energy, Installations, and Environment. “Securing these operations with dedicated, localized microreactor power is a national security imperative and means our critical naval support systems will never go dark, preserving our strategic advantage and ensuring uninterrupted support to our warfighters.”
This cutting-edge technology is being procured through the Department of the Army’s Janus Program in close partnership with the Department of War Innovation Unit (DIU). The selection of Radiant for NWS Crane is not a new or additional effort within the existing Janus Program. The MPP at NWS Crane is accounted for within the August 26, 2026 award announcement which stated the Army expects to build more than 20 total nuclear microreactors on military installations. By leveraging the Army’s Janus contracting vehicle and DIU’s agile innovation framework, the Navy is streamlining the path to deployment to provide NWS Crane with an independent power source and securing an enduring operational advantage for our warfighters.
“The Janus Program was built from day one to deliver real, reliable hardware and systems to solve energy resilience challenges across all of the Services,” said Dr. Jeff Waksman, Principal Deputy Assistant Secretary of the Army for Installations, Energy and Environment. “We are excited to partner with the Navy to place a Janus reactor at NWS Crane, and by doing so to deliver the state of Indiana its first advanced microreactor.”
The State of Indiana has also been a key partner in accelerating the development of advanced nuclear energy. State leadership has leaned forward to help bring this prototype to Crane, underscoring a shared commitment to both national security and local economic growth.
“Indiana is achieving energy affordability and reliability through growth,” said Governor Michael Braun. “We welcome Radiant Industries to Indiana to deploy advanced nuclear energy technology at the Crane Naval base. Under President Trump’s leadership, America is unleashing this robust technology to strengthen our national security by ensuring reliable, resilient power for critical defense operations. At the same time, it supports significant economic opportunity for Hoosier communities through high-quality jobs, new investment, and local business growth. By expanding access to stable, affordable energy, this initiative supports long-term economic development and enhances energy affordability for residents across the state.”
Naval Weapons Station Crane is home to both Crane Army Ammunition Activity and Naval Surface Warfare Center, Crane Division. Crane Army Ammunition Activity produces and distributes crucial joint conventional munitions, and the Naval Surface Warfare Center, Crane Division is responsible for delivering innovative technical solutions and ensuring readiness for the nation’s warfighters. These vital national security requirements demand resilient infrastructure to perform critical weapons development, support electromagnetic warfare, strengthen strategic missions, and enable advanced manufacturing capabilities crucial to the Department of War.
“Our installations are foundational warfighting platforms and ensuring their resilience is essential to supporting the Fleet,” said Vice Adm. Brad Collins, Commander, Navy Installations Command. “By investing in advanced capabilities like this microreactor at Crane, we are providing our Shore infrastructure with the resources needed to sustain the mission and empower our warfighters.”
This milestone at Crane underscores a broader effort across the Department of War to field revolutionary energy capabilities. This procurement allows the Department to rapidly transition concepts into operational reality.
“The Department of War is actively breaking down the barriers that have prevented deployment of nuclear reactors,” said Mike Dodd, Assistant Secretary of War for Critical Technologies. “The selection of Radiant for NWS Crane represents a critical acceleration in our mission. We are not just investing in technology; we are leveraging vital commercial capabilities to deliver an immediate, asymmetric advantage directly to the warfighter.”
Working alongside the Nuclear Regulatory Commission and other partners, experts from the Naval Nuclear Propulsion Program will provide technical expertise and support as the project advances through design refinement, prototype testing, regulatory coordination, site preparation, and ultimately safe deployment of the microreactor at NWS Crane.
The Department of the Navy will proceed with Radiant Industries, Inc. on the next phases of development. These phases include final environmental reviews, localized site design, and regulatory coordination with the appropriate oversight entities and with federal, state, and local partners. The project will continue to adhere to strict safety, physical security, and environmental compliance standards throughout its lifecycle.
