The U.S. military successfully transported a small nuclear reactor from California to Utah using a C-17 aircraft. Defense and Energy officials say the operation shows America's capability to rapidly deploy nuclear power technology for both military operations and civilian purposes.

Defense and Energy Department officials have successfully transported a compact nuclear reactor via military aircraft from California to Utah, showcasing what they describe as America’s ability to rapidly position nuclear power technology for both military operations and civilian applications.

The microreactor, manufactured by Valar Atomics, was moved without nuclear fuel aboard a C-17 transport plane from March Air Reserve Base in California to Hill Air Force Base in Utah on Sunday, February 15, 2026.

This transportation demonstration comes as the Trump administration advocates for accelerated deployment of nuclear power technology across the United States.

Officials from both the Pentagon and Energy Department characterized the airlift as proof of concept for quickly moving nuclear power capabilities to locations where they might be needed for various purposes.
