# Navy Selects Crane Microreactor Supplier

The U.S. Navy selected Radiant Nuclear’s Kaleidos microreactor technology to provide power at Naval Weapons Station Crane in Indiana, which the Navy identifies as its first naval microreactor installation. The project is expected to proceed through environmental review, site development, and technology refinement, involving the Navy, Army, Defense Innovation Unit, and Nuclear Regulatory Commission. The signal does not state a contract value, award date, or solicitation number, so the selection should not be treated as a disclosed contract award.

- Radiant Nuclear is the selected supplier; the planned project phases may create relevant work in environmental review, site development, and technology refinement as implementation proceeds.
- Procurement teams and contractors in defense energy and nuclear technology can use the selection to assess potential capability needs and areas for support, while distinguishing the supplier selection from any separately competed work.
- The source provides no solicitation details or contract amount, so it does not establish a current bid opportunity or a confirmed procurement timeline.
