Army Awards $2.2 Billion to Build Nuclear Microreactors at Five U.S. Military Bases
REL_TIME: 27 Aug 2026 02:45Z · LANG: EN
The U.S. Army has announced up to $2.2 billion in milestone-based contracts awarded to five companies to construct and operate nuclear microreactors at five domestic military bases. Part of 'Project Janus'—an initiative aligned with a May 2025 executive order to accelerate advanced nuclear energy—the program aims to establish energy resilience and independence from vulnerable commercial grids and diesel fuel backups. The selected installations will host up to 20 microreactors producing 1 to 20 megawatts each, with a target operational date of September 30, 2028. While proponents view the initiative as a national security game-changer, critics argue it serves as an expensive, risky subsidy for unproven commercial designs.
// Background
Project Janus was launched in 2025 following executive orders signed by President Donald Trump to accelerate advanced nuclear power development. The Army was mandated to have an operational advanced reactor at a domestic base by September 30, 2028. Historically, the military has experimented with nuclear power, notably with a reactor at Fort Belvoir, Virginia, which in 1957 became the first nuclear reactor to supply power to a U.S. commercial grid for an extended period. The current initiative seeks to transition advanced reactor designs from experimental prototypes to deployable, resilient power sources.
// Key Developments
- The Army selected five defense and energy firms to deploy microreactors at Fort Bragg, Fort Campbell, Fort Hood, Fort Benning, and Fort Drum.
- The milestone-based contracts total up to $2.2 billion over five years, with expectations to build more than 20 microreactors.
- Each microreactor will generate between 1 and 20 megawatts of power, operating independently of the commercial electric grid during emergencies.
- The initiative faces supply chain hurdles, particularly a domestic shortage of high-assay low-enriched uranium (HALEU).
- The reactors will be licensed directly by the Army rather than the Nuclear Regulatory Commission (NRC) to streamline deployment.
// Timeline
-
A nuclear reactor at Fort Belvoir, Virginia, becomes the first to supply electricity to a U.S. commercial grid for an extended period.
-
President Donald Trump signs executive orders to accelerate nuclear power development, setting a September 2028 deadline for an operational military reactor.
-
The Army and the Defense Innovation Unit launch 'Project Janus' at the Association of the U.S. Army Conference.
-
The Army names nine military bases as finalists for the microreactor program.
-
The Army officially awards up to $2.2 billion to five selected companies to build microreactors at five designated bases.
-
The target deadline for the first advanced nuclear microreactor to begin operations at a domestic Army installation.
// Perspectives
[U.S. Army Leadership]
Strongly supportive; views microreactors as essential for national security, combat power projection, and energy resilience during conflicts.
[Selected Defense Contractors (e.g., Radiant, BWXT, Antares)]
Highly optimistic; believe the program validates their technology, accelerates commercial nuclear development, and builds a more resilient nation.
[Nuclear Proliferation Prevention Project (Alan J. Kuperman)]
Highly critical; characterizes the program as an expensive, risky, and dangerous subsidy for uneconomical reactors, bypassing standard NRC licensing.
// Quotes
“We now know that our domestic electric grid is potentially at risk in a conflict. We also know that we will not necessarily be able to move fossil fuels easily wherever we need them to go... So that makes nuclear energy just a natural game changer for the Army.”
“We are building the energy resilience necessary to project combat power globally, without relying on potentially vulnerable external grids.”
“The Army program is using the military’s 'deep pockets to provide a hidden subsidy' to nuclear companies that can’t find private-sector customers for their hypothetical and uneconomical reactors.”
