ARMOR Act of 2025

United States119th CongressS-2389Senate
Updated: Jul 23, 2025

Summary

The bill requires the Secretary of the Army, in conjunction with the Defense Innovation Unit, to implement a pilot program aimed at supplying resilient energy to critical infrastructure at Army installations. This program will deploy fixed facility advanced nuclear micro-reactors or small modular reactors, with an objective to establish this energy source by December 31, 2030. Considerations for the program include contractor ownership and operation, commercial licensing by the Nuclear Regulatory Commission, and potential co-location with artificial intelligence infrastructure and data centers, with reactors capable of up to 300 megawatts and potential grid connection for excess energy. Furthermore, the legislation grants military departments the authority to enter into multi-year contracts , lasting up to 50 years, for energy derived from advanced nuclear reactors. These contracts may consider the value of leased land for siting energy production facilities. Finally, the bill amends existing law to include nuclear energy and nuclear technologies as covered technology categories for the Office of Strategic Capital within the Department of Defense, broadening its investment focus.
