Breaking Defense is reporting that the Army has awarded up to $2.2 billion to five companies to continue work on nuclear microreactor prototypes. The funding is part of the Janus Program, which aims to equip domestic U.S. military bases with these reactors. The Army's goal is to have the first microreactor delivered by the end of September 2028. Breaking Defense said this announcement marks the Pentagon's first major nuclear power agreement and aligns with a broader push by the Donald J Trump administration to support nuclear power.
