Summary
General Atomics Electromagnetic Systems said the Army picked it as one of multiple Janus vendors to advance its GA-TES microreactor toward potential deployment at Fort Hood, Texas.
GA-TES is designed to supply about 5 megawatts of electricity, scalable to roughly 20 MWe, for remote or off-grid military sites during grid disruptions that threaten energy security.
The liquid-metal-cooled design uses self-regulating UZrH fuel and pump-free natural-circulation cooling, features the company says improve passive safety and reduce operating complexity over a 40-year life.
The Army is running Janus with the Defense Department's innovation arm under milestone-based OTA agreements to push commercial nuclear systems from design into operational hardware.
The selection fits a broader Army effort that earlier named five companies for up to $2.2 billion in microreactor contracts, targeting a first base deployment by September 2028.
