U.S. Navy plans first advanced nuclear microreactor at Indiana weapons base by 2028 to provide secure off-grid power for operations
The US Navy plans to install an advanced nuclear microreactor at its Crane, Indiana, weapons facility and aims to begin operation in 2028. The project is intended to supply secure, resilient electricity independently of the commercial grid, supporting critical missions through outages or deliberate disruption while providing operating experience for small-reactor technology on a defense site. Final output, vendor responsibilities and construction milestones remain subject to contracting, licensing and safety review, so the schedule represents a program objective rather than confirmation that a reactor has already been built or authorized for routine service.
