Energy resilience is moving from aspiration to execution inside the Navy: after years of warning about grid vulnerability, the service has formalized a pathway to pilot small modular reactors alongside other dispatchable power at its installations, with a carrier-to-shore test in Norfolk set to demonstrate the operational logic behind the push.
At a Glance
- The Navy has solicited “execution-ready” energy prototypes for bases, explicitly including small modular nuclear reactors (SMRs), with a 99.9% availability target if the public grid fails.
- Congress established a 10-year pilot program to evaluate SMRs or mobile reactors at one or more naval installations, directing the Navy to launch it within a year of enactment.
- A near-term demonstration will use USS Gerald R. Ford to power Naval Station Norfolk from ship to shore, illustrating nuclear-supplied resilience for base operations.
- The Navy is comparing multiple technologies—SMRs, geothermal, storage, and other firm power—rather than committing to a single design path.
What the Navy is doing and why it matters
The Department of the Navy has framed energy resilience as a mission assurance problem, not a green initiative. Its August 2025 solicitation seeks “execution-ready prototypes” that keep installations powered through grid failures, cyber events, and natural hazards, with a stated goal of 99.9% availability—language that treats electricity to the base as an operational dependency on par with fuel and munitions in theater. Small modular nuclear reactors are explicitly in scope, but so are geothermal, long-duration storage, and other dispatchable resources; the mechanism is technology-agnostic by design, letting the Navy measure what actually delivers resilient, controllable power at the installation scale.
This posture aligns with how modern forces fight. Expeditionary logistics are constrained by fuel and infrastructure; a large coastal base with a single utility feed is a strategic liability in a contested environment. By moving firm, on-site generation inside the security perimeter, the Navy aims to keep critical loads—pierside operations, communications, cybersecurity, aviation maintenance, water and fuel systems—up when the surrounding grid is dark. The question is no longer whether the grid is vulnerable; it is what mix of on-site technologies best closes the vulnerability window.
The statutory backbone: a 10-year pilot for installation nuclear power
Congress gave the Navy explicit authority and direction to test nuclear options for base energy. Under 10 U.S.C. chapter 873, the service must initiate within a year a ten-year pilot at one or more installations to assess small modular or mobile reactors for installation needs and security benefits. That mandate turns a concept into a programmatic obligation, with the Assistant Secretary of the Navy for Energy, Installations, and Environment as the responsible official. The statute does not pick technologies or sites; it compels disciplined evaluation—performance, safety, integration, and mission value—inside a defined pilot structure.
Crucially, the pilot’s scope is installation energy, not propulsion. That distinction unlocks different licensing, siting, physical security, emergency planning, and interconnection questions than the Navy solves aboard ships. It also forces a comparative lens: how do nuclear options stack up against diesel microgrids, advanced storage, geothermal, and hardened grid ties over a full lifecycle?
A near-term proof: powering Norfolk from a nuclear carrier
Before a land-based reactor ever breaks ground, the Navy intends to demonstrate the core use case—nuclear-supplied resilience to a base—using an asset it already operates. Acting Secretary of the Navy Hung Cao told lawmakers that USS Gerald R. Ford will power Naval Station Norfolk in a planned summer test, a statement backed by a Navy spokesman identifying Norfolk as the first location. Technically, this is straightforward: aircraft carriers routinely export power in limited scenarios, and the shipboard reactor is licensed and crewed. Strategically, it is clarifying. The demonstration will show how much load can be supported, how shore infrastructure handles nuclear-quality power delivery, and how operations ride through a simulated or actual grid loss.
Readers should keep two threads separate. The Norfolk test exercises carrier-to-shore capability; the pilot program evaluates permanent, shore-based options. Demonstrating one does not decide the other’s licensing pathway or economics, but it does show commanders and installation managers what resilient, always-on power does for the operational tempo and recovery profile of a major naval hub.
Multiple technical pathways, one operational yardstick
The Navy’s solicitation is deliberately broad. SMRs sit alongside geothermal systems, battery energy storage, and “other dispatchable” solutions—an architecture intended to pit options against the same operational yardsticks: availability during grid outages, controllability to follow base loads, black-start capability, cybersecurity, maintainability, and integration into existing distribution systems. In practice, a resilient installation rarely rests on a single asset. Expect portfolio designs that pair firm power—nuclear, geothermal, or reciprocating engines—with storage, upgraded switchgear, and islanding controls to cover transients, maintenance windows, and refueling cycles.
One early step toward site readiness is the Navy’s collaboration with the local utility. Naval Weapons Station Yorktown signed a memorandum of understanding with Dominion Energy Virginia to assess a base-sited power plant, including an SMR option, positioning the installation to evaluate interconnection and environmental baselines if a nuclear alternative advances. These utility partnerships matter: whether the end state is an SMR, a geothermal plant, or a hardened microgrid, interconnection and protection schemes must be engineered with the local grid operator.
Where the program stands: pilots, candidates, and timelines
The record supports three firm points. First, the Navy has moved from concept to procurement signal, asking industry for execution-ready resilience prototypes with stringent availability goals. Second, Congress has put a legal floor under a ten-year pilot to test SMRs or mobile reactors at one or more naval installations, with initiation required within a year of enactment. Third, the service is preparing a visible demonstration of nuclear-supplied shore power at its largest Atlantic base using an aircraft carrier.
Outside those anchors, details remain programmatic rather than prescriptive. Reporting points to several Virginia installations as candidates, but the Navy has not published a list of selected sites, specific reactor designs, construction schedules, or licensing milestones. That is consistent with the pilot statute’s design: start with feasibility and demonstrations, compare alternatives, then downselect on performance and mission value. The solicitation’s 99.9% availability is a target the prototypes must credibly meet in evaluation and test, not a claim that any specific system has already delivered it at an installation scale.
How this fits the defense energy arc
This naval effort sits squarely in a broader Department of Defense arc: shrink the logistics tail and harden critical nodes with on-site, reliable power. Earlier initiatives—ranging from the Defense Science Board’s calls for mobile, resilient energy to the Department’s Project Pele mobile microreactor program—reflect the same operational impulse: reduce dependence on fragile supply chains and civilian infrastructure, especially for forward or strategically vital bases. The Navy’s pilot brings that logic home to domestic installations, where uninterrupted power underwrites everything from ship maintenance to command-and-control. Success will be judged less by ideology than by operational effect: does the base stay up when the city goes down, and at what lifecycle cost relative to other firm-power options?
What to watch next
Three developments will signal momentum. First, publication of pilot sites and evaluation criteria from the Assistant Secretary’s office, including how the Navy weights availability, safety, lifecycle cost, and integration risk under the chapter 873 mandate. Second, technical results from the Norfolk carrier-to-shore demonstration—power delivered, loads supported, and lessons for permanent shore architectures. Third, award announcements under the resilience solicitation that reveal which technologies cleared the “execution-ready” bar and how the Navy structures performance guarantees around the 99.9% target. Together, these steps will show whether SMRs earn a place in the Navy’s installation energy portfolio—or whether geothermal, advanced storage, and conventional firm generation, in combination, close the resilience gap more effectively.
