The US Air Force has selected three companies to develop microreactor technology for powering military bases, according to Bloomberg reporting. The selection represents part of the military's efforts to develop alternative energy sources for its facilities.

Separately, the CEO of USA Rare Earth discussed the United States' position in achieving independence from foreign suppliers of critical materials. The executive characterized the US as being in the "early innings" of developing domestic rare earth capabilities.

The Air Force's microreactor initiative aims to provide reliable power sources for military installations, potentially reducing dependence on traditional power grids. Microreactors are small nuclear power systems designed to generate electricity in remote or challenging environments.

Rare earth elements are critical materials used in various technologies including defense systems, electronics, and renewable energy equipment. The US has historically relied heavily on foreign suppliers, particularly China, for these materials.

Both developments reflect broader US government efforts to strengthen domestic supply chains and reduce reliance on foreign sources for critical technologies and materials. The initiatives span across defense and energy sectors as part of national security considerations.
