Pentagon Announces Indiana's First Nuclear Reactor at NWS Crane, Supply Chain Window Opens Now

The Department of Defense announced September 10 that it will install an advanced Micro Modular Reactor at Naval Weapons Station Crane in Martin County by September 2028, the first power-producing nuclear reactor in Indiana's history. The project runs through the Army's Janus Program. The specific vendor has not yet been named.

Janus is one of a small handful of near-term military microreactor awards (alongside Project Pele, where BWXT was already selected, and the Eielson Air Force Base deployment) that will determine which vendors reach commercial licensing first. Under the NRC's proposed Part 57 microreactor licensing rule, published April 2026 with finalization expected no earlier than mid-2027, operational data from a military deployment can accelerate commercial licensing for the same design. The regulatory clock is the risk: Part 57 finalization may not land until mid-2027, leaving as little as twelve to fifteen months between rule finalization and the September 2028 installation deadline.

Whoever wins Crane gains a reference deployment that materially de-risks commercial licensing and improves competitive positioning for follow-on utility contracts. Crane already anchors over $3 billion in annual economic impact for southern Indiana. If your company has any existing supplier relationships or certifications touching the defense tech or nuclear ecosystem at Crane or WestGate, the time to assess whether you can enter Janus Program procurement is now, before the vendor is named and the supply chain closes.
