The U.S. military and NASA have power problems. Nuclear microreactors might solve both

The U.S. military and NASA are helping accelerate the development of nuclear microreactors, a smaller class of reactor intended for demanding environments on Earth and beyond.

The effort comes as interest grows in a new generation of nuclear technology. Next-generation reactors are also being considered as a way to support the expanding power needs associated with the artificial intelligence boom. However, the military and NASA are focusing on more compact systems with specific operational uses.

Power for remote and high-risk environments

For the U.S. military, microreactors could provide power at remote bases and support future combat applications. Their development reflects an effort to address energy needs in locations where dependable power is especially important.

The technology could also extend nuclear power into missions that are difficult to support through conventional energy systems. The source identifies remote military bases and combat as central areas where microreactors may have an impact.

A role in deep-space exploration

NASA is pursuing the technology for a different but related challenge: supplying energy for deep-space exploration. Smaller reactors could help support missions far from established power infrastructure, although the source does not specify particular spacecraft, timelines or reactor designs.

The involvement of both agencies gives microreactors importance across defense and space exploration. Their work is part of a broader push toward a new nuclear age, while the practical focus remains on developing compact systems for remote and demanding missions.

What comes next

Microreactors remain under development, and no specific deployment date or commercial outcome is provided. For now, their potential lies in serving military operations and deep-space missions while contributing to wider interest in next-generation nuclear power.
