The ARMOR Act requires the Secretary of the Army, with the Defense Innovation Unit, to run a pilot program deploying fixed‑facility advanced nuclear micro‑reactors or small modular reactors at selected Army installations in the United States. The objective is to provide resilient energy to critical Army infrastructure by December 31, 2030, with reactor output up to 300 megawatts and the potential to connect to the civilian grid to sell excess energy where feasible.
The bill also authorizes long‑term energy contracts for these reactors (up to 50 years), sets a path to expand participation to other DoD components, and adds nuclear energy and technologies to the Office of Strategic Capital’s covered categories.
At a Glance
What It Does
Requires a pilot program at Army installations to deploy fixed‑facility advanced nuclear reactors (micro‑reactors or SMRs) to deliver resilient energy, with up to 300 MW output and potential grid interconnection.
Who It Affects
Directly affects Army installations and the DoD energy program, nuclear reactor vendors, and NRC licensing processes; may involve nearby communities and grid operators where interconnections occur.
Why It Matters
Creates a path to harden military energy resilience, reduces dependence on traditional grids, and signals a long‑term procurement approach for military energy needs with private sector partnerships.

What This Bill Actually Does
The ARMOR Act puts the Army in the lead to test a fixed, facility‑based nuclear reactor solution for critical infrastructure. Working with the Defense Innovation Unit, the Army would select installations and deploy a fixed facility advanced nuclear micro‑reactor or small modular reactor to provide a reliable energy source.
The goal is to have a functional, resilient energy supply for these installations by 2030, with reactors capable of producing up to 300 MW. Where feasible, the reactors could connect to the civilian grid to sell any surplus energy, creating a potential revenue stream.
The bill also authorizes long‑term contracts for operating energy facilities—up to 50 years—and contemplates expansion to other military departments upon request, with funding drawn from applicable appropriations. In licensing terms, the project would lean on NRC processes with priority handling, following the 2024 Accelerating Deployment of Versatile, Advanced Nuclear for Clean Energy Act.
Finally, the ARMOR Act broadens the Office of Strategic Capital’s mandate to include nuclear energy and technologies as covered categories. This combination aims to accelerate deployment of resilient energy while preserving a measured regulatory and budgetary pathway.
The Five Things You Need to Know
The pilot program requires deployment of fixed‑facility advanced nuclear reactors at identified Army installations.
Each reactor is limited to a power output of up to 300 MW.
Excess energy, when feasible, may be sold to the civilian grid.
Contracts for energy from these reactors can run up to 50 years, funded from applicable appropriations.
Nuclear energy and technologies are added to the Office of Strategic Capital’s covered categories.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short Title
Beitamend by Section 1 to designate the act as the Advanced Reactor Modernization for Operational Resilience Act of 2025 (ARMOR Act). This section sets the formal citation for the legislation as it proceeds through Congress.
Pilot program to provide resilient energy to Army installations
This section directs the Secretary of the Army, with the Director of the Defense Innovation Unit, to carry out a pilot program deploying fixed‑facility advanced nuclear micro‑reactors or SMRs at Army installations identified by the Secretary. The objective is to provide resilient energy to critical infrastructure by December 31, 2030. The program contemplates ownership structures (corporate contractor ownership, licensing as a commercial reactor with NRC input, or co‑location with AI/data centers) and requires consideration of licensing priority and grid interconnection where feasible.
Multi‑year contracts for energy from advanced nuclear reactors
This section authorizes the Secretary of a military department to enter into contracts for energy production facilities powered by advanced nuclear reactors for up to 50 years. Funding may come from any appropriate appropriation. The clause also allows consideration of land lease value as part of the contract negotiations, recognizing the asset‑heavy nature of nuclear energy facilities.
Modification of covered technology category for Office of Strategic Capital
This section amends 10 U.S.C. 149(e)(2) to add “Nuclear energy” and “Nuclear technologies” as covered technologies for the Office of Strategic Capital, signaling a strategic investment posture toward domestic nuclear energy capabilities and related technologies.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Army installation energy managers gain a dedicated resilience pathway for critical infrastructure and a predictable procurement channel for energy needs.
- DoD energy program leadership benefits from a standardized, long‑term procurement framework and potential private‑sector partnerships to advance mission readiness.
- Nuclear reactor vendors and operators stand to gain from a defined pilot and potential multi‑decade contracts, accelerating deployment and scale.
- NRC and related regulatory bodies receive a clearly prioritized path for licensing advanced reactors, potentially accelerating review processes.
- The broader national security ecosystem may benefit from diversified energy sources and reduced operational risk through energy resilience.
Who Bears the Cost
- Federal budgets must absorb upfront and long‑term financing for pilot deployments and potential infrastructure upgrades at installations.
- Contractors will incur development, construction, and operating costs, with performance and regulatory compliance risks tied to pilot outcomes.
- Local communities near installations may experience interim environmental and safety scrutiny and require communications and assurances during siting and construction.
- Regulatory agencies will need to manage an increased licensing and oversight load tied to pilot reactor projects.
- Long‑term procurement cycles could redirect funds from other energy programs if pilot results favor expansion.
Key Issues
The Core Tension
The central dilemma is balancing aggressive deployment of secure, reliable energy for critical Army infrastructure with the practical, regulatory, and budgetary realities of large‑scale nuclear projects: speed and mission readiness versus safety, licensing timelines, and long‑term financial commitments.
The ARMOR Act introduces a high‑stakes path to militarize nuclear energy for resilience, but it embeds a number of tensions. First, the cost and timeline of deploying fixed‑facility reactors on active or potentially sensitive military sites could strain budgets and require rapid regulatory alignment.
The long‑term contracts — up to 50 years — shift budgeting and financial planning toward a capital‑intensive asset class with uncertain civilian market dynamics. Second, licensing risk remains real: while NRC prioritization is stated, siting and operation of nuclear facilities within or near military infrastructure raises safety, environmental, and cybersecurity considerations that need robust risk management.
Third, there is a policy tension between the military aim for energy independence and the realities of civilian grid interconnections, including ownership and revenue sharing from any sold excess energy. Finally, expanding the Office of Strategic Capital’s scope to include nuclear energy and technologies elevates strategic competition risks and requires careful governance to balance innovation with accountable stewardship.
