Deployable Nuclear Power Emerges as Strategic Imperative for U.S. Military Resilience Amid Great-Power Rivalry

The U.S. military's push for advanced nuclear technologies, particularly small modular reactors (SMRs) and microreactors, reflects a fundamental shift toward energy security as a pillar of national defense. A May 2025 White House executive order (EO 14299) directs rapid deployment of these systems to power critical defense facilities, marking institutional acknowledgment of vulnerabilities in the civilian grid to cyberattacks, sabotage, and extreme weather.

The Army's Janus program has identified nine installations—including Fort Bragg, Fort Hood, and Redstone Arsenal—for potential microreactor deployment, targeting operational capability by 2030. Parallel efforts by the Defense Innovation Unit (DIU) under the Advanced Nuclear Power for Installations (ANPI) program have qualified eight commercial vendors, emphasizing "behind-the-meter" setups that bypass long-distance transmission.

Recent demonstrations, such as the Pentagon's February 2026 airlift of a 5-megawatt microreactor prototype, underscore transportability for forward operations. This aligns with historical precedents like the defunct Army Nuclear Power Program but gains urgency from AI-driven power demands and competition with China over industrial and semiconductor capacity.

Fuel supply remains a critical gap: many designs require High-Assay Low-Enriched Uranium (HALEU), currently dependent on foreign sources including Russia. DOE initiatives aim to build domestic enrichment capacity, mitigating strategic risks.

These developments connect undercovered patterns in defense-industrial resilience, where distributed nuclear generation could enhance survivability without competing for civilian power.
