A British nuclear start-up is negotiating a deal that could see the first floating nuclear power plant built for the Pentagon and moored off a United States military base. The project would use a compact reactor on a ship-like platform to feed electricity into the American grid, with backers pitching it as a way to satisfy both military needs and the surging power appetite of artificial intelligence data centres. If it proceeds, it would mark one of the most radical experiments yet in how to generate and deliver nuclear energy.
The talks highlight a collision of priorities: energy security for the Pentagon, climate and grid pressures on the American power system, and public unease over nuclear risks at sea. Supporters see a chance to pioneer a new export industry for Britain, while critics warn of “novel” safety and regulatory gaps that governments have barely begun to address.
The British start-up behind the Pentagon talks
At the centre of the negotiations is Core Power, a British nuclear start-up headquartered in Chiswick in west London that has spent years promoting maritime nuclear concepts. The company is in discussions with the Pentagon over a floating plant that would be stationed at a waterside military base, then connected into the wider American grid to supply civilian demand as well as defence facilities. Reporting on the project describes Core Power as part of a new wave of British firms seeking to commercialise advanced reactors at sea, positioning Chiswick as an unlikely hub for nuclear innovation linked directly to the United States security establishment.
The concept under discussion involves a vessel or barge fitted with one or more compact reactors, kept at a secure harbour and plugged into onshore infrastructure. According to coverage of the talks, it is understood such a plant would be “plugged in at a base but primarily used to generate power for the American electricity grid,” with the Pentagon acting as anchor customer and host for the facility. The same reporting notes that the reactor design developed by Core Power would not be used in the United Kingdom because of what officials describe as “novel” risks, a choice that highlights how the company is looking abroad for its first commercial deployment rather than seeking approval on home soil, as set out in coverage of the.
Why the Pentagon wants power at sea
The Pentagon’s interest in floating nuclear power is rooted in a looming energy crunch, particularly from artificial intelligence and other data intensive technologies that require constant, high quality electricity. Reports on the negotiations describe how the Pentagon is exploring floating reactors as a way to power an “AI hungry” grid by 2028, with one account stating that a British nuclear start-up is working with the department to construct a plant that could be operational within that timeframe. The project is presented as part of a broader push to secure reliable baseload power for critical infrastructure, rather than relying solely on an increasingly stretched mix of gas, renewables and long distance transmission.
One source notes that the initiative follows an executive order by the United States president instructing Pentagon chiefs to accelerate the development of advanced nuclear technologies, a directive that explicitly links defence planning to next generation reactors. In that context, a floating plant is framed as both a resilience measure for military bases and a contribution to the civilian grid, with the Pentagon effectively underwriting early deployment risk. The same reporting describes the plan as highly ambitious within the industry and attributes the framing of the project to a piece written “By Newsroom” that emphasises the aim of serving an AI driven power surge by 2028, a target referenced in analysis of the.
Inside the floating reactor concept
Core Power’s concept draws on decades of naval nuclear experience but applies it to civilian electricity generation, with the plant effectively acting as a mobile power station that can be towed into place and connected to shore. The company, described as a British nuclear start-up headquartered in Chiswick, London, is working on floating nuclear power plants that could be stationed at waterside military bases and used to supply both base operations and the wider grid. The design is pitched as modular and scalable, potentially allowing multiple units to be deployed over time to meet rising demand, according to reports that profile Core Power in.
Details emerging from the talks suggest that one of the first plants could be moored at a United States base as soon as 2028, with the vessel fitted with nuclear reactors and connected via high capacity cables. Reports indicate that the facility would be built by the British company but operate under Pentagon oversight, with American regulators and defence authorities shaping safety and security protocols. One account of the project mentions that the plan is seen as part of a broader effort to expand advanced nuclear power during a second presidential term, and that the number 38 is cited in relation to industry metrics in coverage of the proposal, a detail that appears in reporting on Pentagon.
Regulatory shortcuts and safety fears
The potential Pentagon deal has already drawn fire from nuclear critics who argue that floating plants risk bypassing established safety regimes. A briefing on “Floating Nuclear” warns that plans involving a British company in talks to build a plant for the Pentagon could sidestep traditional nuclear regulators, since the facility would sit in territorial waters under defence control rather than on civilian land. The same source flags concerns that such projects might be pushed through under security exemptions, with limited public scrutiny, and groups opposed to nuclear power argue that this approach could set a precedent for looser oversight of advanced reactors at sea, as highlighted in the Floating Nuclear briefing.
Those concerns are sharpened by the decision not to pursue the Core Power reactor in the United Kingdom because of “novel” risks, even as the company seeks to deploy it for the Pentagon. Commentators point out that if British authorities are reluctant to license the technology at home, relying instead on an American defence contract could be seen as exporting risk. A separate summary of the debate notes that “Floating Nuclear” plans involving a British company and the Pentagon could bypass regulators and that the initiative is tied to a wider push for advanced nuclear technologies under an executive order, a linkage described in campaign group material.
Strategic stakes for Britain and the United States
For Britain, the project represents a chance to turn advanced nuclear engineering into export revenue and geopolitical influence, even as domestic regulators hold back. Reports describe how the reactor developed by Core Power, a Chiswick based company, will not be used in the United Kingdom because of “novel” risks, yet could be installed at a United States base as soon as 2028. The same coverage credits Matt Oliver Indu as the journalist explaining that the plant would be fitted with nuclear reactors on a floating platform and connected at a base, underlining how British industry is looking to American defence contracts to commercialise technology that has not cleared national hurdles, as outlined in reporting on the.
For the United States, the stakes are both strategic and symbolic. The Pentagon would gain a new tool to guarantee power for critical bases and to support the wider American grid at a time when demand from data centres and AI systems is rising sharply. The arrangement also reflects a deepening technological partnership with a British supplier, reinforcing transatlantic links in advanced nuclear fields. A summary of the story notes that a British nuclear start-up headquartered in Chiswick, London is developing floating plants that could be stationed at waterside military bases and that the Pentagon is eyeing such reactors to power an AI hungry grid by 2028, a strategy that aligns defence planning with civilian energy security, as described in analysis of the and in commentary on Pentagon.
