US Military Transports Next-Generation Nuclear Reactor to Utah

Developing StoryLast updated MAY 18
SUMMARY

On February 15, 2026, a next-generation mobile nuclear reactor was successfully transported via C-17 aircraft from March Air Reserve Base in California to Hill Air Force Base in Utah, marking the first time a nuclear reactor has been moved by this type of aircraft. As of May 18, 2026, the U.S. Department of Energy has awarded over $94 million to American companies to expedite the deployment of small nuclear reactors, supporting the rapid deployment of nuclear power. The reactor, designed to generate 5 megawatts, is being tested at the Utah San Rafael Energy Lab as part of 'Operation Windlord,' aligning with the Trump administration's push to promote nuclear energy for military and civilian use. On March 4, 2026, TerraPower LLC received federal approval to build America's first commercial plant using next-generation reactor technology in Wyoming, with operations expected by 2031.
