Pentagon backs X-energy’s mini nuclear reactor to boost military energy resilience

The US Department of Defense (DoD) and the Department of the Air Force have signed an agreement with X-energy Reactor Company to advance the development of its commercial microreactor.

The agreement has been made with the goal of deploying advanced nuclear technologies at DoD installations to support national security. It aligns with President Donald Trump’s executive order issued in May 2025.

It will support the design and development of X-energy’s XENITH microreactor under the Advanced Nuclear Power for Installations (ANPI) program, which DIU leads in partnership with the Department of the Air Force.

The program aims to accelerate the deployment of next-generation microreactor technologies to provide power at military installations.

It enables government agencies to engage with private companies under a flexible contracting mechanism that allows for faster development and deployment of commercial nuclear systems.
