# US Army Janus Program nuclear microreactor deployment > Live situation record from CLSTR: https://clstr.news/situations/us-army-janus-program-nuclear-microreactor-deployment > Updated: 2026-08-26T20:01:16.000Z. Sources: 42. Developments: 2. The U.S. Army has launched the Janus Program, an initiative to deploy advanced nuclear microreactors across five military bases to ensure energy resilience and independence from the commercial electrical grid. The program aims to install more than 20 compact, mobile microreactors, each generating between 1 and 20 megawatts of electricity. The Army has awarded up to $2.2 billion over five years to five companies—Antares Nuclear, BWXT Advanced Technologies, General Atomics Electromagnetic Systems, Radiant Industries, and Westinghouse Government Services—to own, construct, and operate these units. Army officials stated the initiative is intended to “mitigate risks associated with potential grid failures, cyberattacks, or disruptions in fossil fuel supply chains during conflicts.” The program seeks to protect critical infrastructure from disruptions caused by cyberattacks, physical sabotage, or natural disasters. While funding is milestone-based and contingent on technical performance, the program is part of a broader push to advance next-generation nuclear technology for military and potential future civilian applications. The specific company and site assignments are as follows: • Antares Nuclear: Fort Bragg, North Carolina • BWXT Advanced Technologies: Fort Campbell, Kentucky • General Atomics Electromagnetic Systems: Fort Hood, Texas • Radiant Industries: Fort Benning, Georgia • Westinghouse Government Services: Fort Drum, New York BWXT has been selected as the first vendor assigned a specific site at Fort Campbell, Kentucky. Under the program, BWXT will deploy its 20-megawatt-electric BWXT Advanced Nuclear Reactor (BANR). The company plans to begin site construction in late 2028, with operations expected to commence in the early 2030s. The first unit under the program is projected to be operational by September 30, 2028. ## Claims - Five selected companies will receive up to $2.2 billion over five years to own, construct, and operate the microreactors.
