The United States Army is on the hunt for a game-changing piece of kit. It's not a new gun, it's not a new tank, it's not a new helicopter. It's a nuclear reactor, or more specifically, a nuclear micro-reactor.
Under a brand new initiative dubbed the Janus Program, the U.S. Army wants to bring its first micro-reactor online within just three years or less, and once the Janus Program has established proofs of concept, America is going to build.
If the U.S. Army has its way, then before long, every military base in the United States could be powered by its own micro-reactor, with the technology spreading to other U.S. bases across the globe.
But even though the scope of the technological ambition of the Janus Program is impressive, well, we are a front to co-suspect that there's an even bigger story waiting to be told.
If it succeeds, the Janus Program will revolutionize the way that global militaries power their operations, but it'll also pave the way for America to go head-to-head with China in a global nuclear energy competition that is only just getting started.
For the United States military, the Janus Program could be a game-changer, but if Janus reaches its full potential, then it could help shape the global balance of power for the next century or more. On Tuesday, October 14, 2025, the United States Army revealed the Janus Program for the very first time.
Announced in partnership with the U.S. Department of Energy and the Cutting-Edge Defense Innovation Unit through the Pentagon, also known as Unit X, the Janus Program's objective is straightforward, even if it's going to be highly challenging to achieve.
The program's primary purpose is to develop a cutting-edge, fully operational nuclear micro-reactor, a prototype that can demonstrate its ability to power a U.S. military installation. Once a working micro-reactor is chosen, the U.S. Army wants to build micro-reactors in bulk, placing them at the heart of American military installations at home and abroad.
Now, in order to understand the program, we first have to understand the technology that it's going to rely on, the nuclear micro-reactor, which is pretty much exactly what the name would suggest. A nuclear micro-reactor is a tiny nuclear reactor, generally able to produce anywhere from a single megawatt of electricity to about 20 megawatts.
They're easy to transport by land, air, or sea, and as such, they can be deployed in a pinch and used to supply power in areas where traditional power infrastructure has either been disabled or just doesn't exist.
Although the distinction can be somewhat blurry in practice, a micro-reactor is generally classified as being a step below the next smallest kind of nuclear reactor, a small modular reactor, which would produce anywhere from 20 to 300 megawatts.
Micro-reactors, like all other nuclear reactors currently in operation across the globe, rely on nuclear fission, and the ones that the US wants to build via the JANUS program would utilize uranium that's enriched to less than 20%.
Also specific to the JANUS program, the micro-reactors in question are intended to be built in a way that makes meltdowns physically impossible, making them a safe, effective way to provide continuous power for years at a time.
They're easy to transport, easy to install, easy to operate, and immensely reliable, or at least they should be if they can be built and replicated at scale. The immediate reason to initiate the Janus program, according to the US Army, is because of an increased need for energy resilience.
Right now, the US military typically doesn't build its own power plants to sustain its bases, and certainly not on US soil.
Instead, bases tap into whatever power source is available to the surrounding community. If, say, a base is positioned in an area that relies on hydropower, then it'll draw power from the same hydropower source as nearby cities and communities.
The same goes for a power plant that might use fossil fuels, or in some parts of the US, army installations draw upon nuclear power.
But regardless, the army's energy sources are dictated by local availability, and while the army might install supplemental infrastructure like solar panels or wind turbines to cover some of its own energy needs, those secondary sources are nowhere near enough to be able to power an entire base if that outside supply of power were to be cut off for any
Reason.
Instead, according to a senior army leader speaking to the American press before Janus was announced, the critical power resiliency that US bases rely on are fully dependent on fossil fuel sources.
That means that if, let's say, something happened in the United States to collapse a regional or national power grid, army installations would only be able to provide backup power using fossil-fueled power generators for as long as their fuel reserves took to dry up.
Quoting the same army leader, you have a certain number of backup power days, but that is a huge vulnerability. According to a nationwide requirement for American military facilities known as Black Start, US bases must be able to operate without an external connection to a power grid in case of an emergency.
Right now, though, they can only meet those expectations for a limited time before power is either restored or America's homeland defense apparatus starts going dark.
To address that problem, the army intends to recruit the help of an as-yet unknown number of American companies, probably around nine, each of which will be charged with building a micro-reactor prototype.
Each of those prototypes will be delivered to an army base on US soil, put into operation for a bit, and used to collect data so that each company can tweak their design, create a better second prototype, and then test that prototype out before iterating again and again for as many attempts as it takes to possess a model that's ready for commercial
Production.
Right now, it's not yet clear whether the US will ultimately decide on just one commercial-grade system, or whether several companies might be asked to create their own separate production lines, potentially building in a level of design resilience and versatility that could make the program even more useful.
What is clear, however, is the deadline. Operating nuclear micro-reactors on US soil no later than the autumn of 2028. Once winning models have been selected, the US Army intends to provide micro-reactors from the Janus program to power each of its military bases on US soil.
So, those reactors will be used to provide a sustained...... reliable source of backup power in case of a blackout to the wider power grid as more commercial grade copies of these reactors become available the army could conceivably switch its bases over to a state of full dependence on their own nuclear energy source with multiple reactors at the same site
In case the primary reactor were to become inoperable those micro reactors could be adopted by other branches of the u.s military each of which have to be energy resilient in their own right since the power needs of most u.s installations fall well below 20 megawatts janus micro reactors could conceivably provide excess power to surrounding communities
Especially to the homes of service members who live off base and with enough time and proof of their reliability janus micro reactors could conceivably be shipped around the world providing power to american overseas bases on friendly territory and potentially even forward operating bases in contested environments across the globe that would allow the u.s to

The new set of high-powered nuclear energy companies similar to the way that america's push to commercialize its spaceflight operations gave rise to spacex sierra blue origin axiom and others even before introducing any outside context we'd imagine that much of the value of america's new janus program is obvious in a strategic sense the ability to keep the

Enough power supply to deploy and utilize a range of energy intensive systems would fundamentally change the way that the u.s and its allies think about deploying abroad when it comes to nuclear energy the arrival of companies that can mass produce military-grade micro-reactors could transform the entire industry and any company that can get on the game
Early stands a chance at rapidly growing into one of america's most important military industrial partners the u.s army could even become a domestic energy provider taking parts of the country that are chronically undersupplied and introducing systems that can provide abundant safe nuclear power indefinitely but it's when we start to zoom out from the janus
Program itself that the true potential of an american-made commercially produced military-grade nuclear micro reactor can really start to come into focus as we said at the outset of today's episode we're going to focus on drawing the through lines that lead from the janus program to a global and possibly world-changing competition between the u.s and china
But in order to get there from here we first got to take a detour through the US energy industry to understand why the United States could be looking at a nuclear energy renaissance.
For the United States, project genius is hardly the first time that the idea of a microreactor has been thrown about. In fact, the subject was first broached in the US all the way back in 1939, when Manhattan Project scientists turned their attention to the potential use of a microreactor to power a nuclear submarine.
In fact, the first nuclear-powered submarine was powered by a device that would qualify, at least broadly, as a microreactor. In the 21st century, the United States has been working to stimulate the development of microreactors and small modular reactors for over a decade, while NASA demonstrated the use of a teeny tiny microreactor back in 2018.
The US Department of Energy has been working on a 100 kilowatt reactor called Marvel for years now in the northwestern state of Idaho, and it's expected to reach criticality for the first time in 2026.
The Pentagon has invested in a project known as PALA, intended to build a prototype mobile nuclear reactor that could fit inside a 20-foot shipping container, as well as an initiative intended to supply nuclear microreactors at installations used by America's Department of Defense, recently and semi-officially renamed to the Department of War.
Until now, however, federal microreactor initiatives in the United States have been slow to take shape, treated as a second-tier funding priority, and just a small subset of the many, many, many experimental projects that the United States funds every year.
Private industry has been slow on the uptake, partially due to the high costs of development and the lack of commercial demand, and partly because of the other logistical and cultural challenges, including an enduring skepticism across much of the United States toward nuclear energy.
But right now, in the mid-2020s, microreactors and other miniaturized nuclear energy initiatives are starting to gain momentum. Companies like Westinghouse, BWX, and Bill Gates' TerraPower are working to fill the gap, powered by funds from companies on the scale of Amazon, Alphabet, Nvidia, and others.
And in fact, those companies may soon be a part of the Janus program.
Eight companies, including all of the ones that we've named except TerraPower, were cleared in April of 2025 to build potential technology demonstrators for the U.S. Department of Energy, and one of them, Radiant Industries, has already agreed to deliver a microreactor to a U.S. military base under a different program.
Public polling in the United States suggests that the American people are coming around to nuclear energy, while the finance world is signaling that nuclear energy is becoming an increasingly attractive, low-risk target for massive future investment.
Driving the change is a combination of skyrocketing energy demand across the U.S. and a flagging energy sector that's been struggling to keep up.
While the United States is far from a true energy crisis in the way the political operatives in Washington have claimed, the nation is facing heavier and heavier demand for the energy it can supply.
The U.S. relies on infrastructure that's deteriorating and vulnerable to cyberthreads. while also trying to navigate a back-and-forth transition toward, and then away from, and then toward renewable energies again, depending on the party that controls Washington.
Energy prices are rising for ordinary consumers, utility companies have made a habit of skimming off the top, and investments to address those issues are sorely lacking.
Meanwhile, AI data centers require incredible amounts of energy in order to stay operational, and those data centers are proliferating faster than ever.
Tech companies are already working to find ways to bridge the gap, including Microsoft's agreement to consume the energy generated from the Three Mile Island nuclear reactor, set to be reopened and restarted for that very purpose in 2028.
Nuclear micro-reactors and small nuclear reactors have the potential to be the answer, powering data centers and other energy-intensive business endeavors all by themselves, and lessening the strain on local communities.
Micro-reactors in particular could power individual towns or rural communities all by themselves, with no need to connect an external power grid, and none of the headaches that come with trying to sustain hydropower, solar, wind, or local fossil fuel-powered operations on a daily basis.
Micro-reactors and small modular reactors are the answer, but right now, even with growing private investment, the commercial nuclear sector is frozen in place. In order to justify larger investments, companies need to be able to point to a clear demand for their reactors.
But without large-scale investment, communities, states, companies, and other potential clients aren't willing to place orders. That's where the Janus program comes in, with the potential to change everything.
Introduce a major government procurement initiative like this one, designed to fund proposals and entertain iterative design processes from several companies at once, and America's miniaturizing nuclear industry could get the shot in the arm that it really needs in order to begin mass-producing nuclear reactors and demonstrating that they can work at scale.
Not only that, but huge investments from the US military would send a powerful signal to the private companies that are already backing these sorts of technology.
With a program like Janus, the Army can show that miniaturized nuclear energy is a field that the US government believes in, and where companies that invest today could earn themselves extremely lucrative contracts with the Pentagon tomorrow.
At a moment when American nuclear enterprise needed something to come along and give the entire industry a push in the right direction, the Janus program is here to deliver.
So, we understand the Janus program, we understand its potential impact on America's renewing nuclear industry, and now it's time we turn to China. At this point in today's episode, we've got to be very clear.
What we discuss from this point forward about the potential, ultimate objectives of the Janus program have not yet been officially confirmed by the US military, or to the best of our knowledge, even implied by anonymous US sources.
This is just your friendly team of analysts here at France.co putting together some pieces of an- So, from this point forward, we'd encourage you to treat any conclusions for what they are. Educated conjecture, but conjecture nonetheless.
But before offering any conclusions, we've got to tell you China's side of this story, where miniaturized nuclear technology has been a critical area of focus for years now.
China is working at a breakneck pace to produce as much nuclear energy as possible, as quickly as possible, and it's on track to surpass the United States in its nuclear capacity by or before 2030.
While most of China's short-term increases in capacity will come by way of traditional sprawling reactors, the nation is also leading the way in micro-reactors, and especially small modular reactors, those somewhat bigger reactors that generate anywhere from 20 to 300 megawatts of power when fully operational.
Back in 2023, China started commercial operations at the first fully operational small modular reactor in the world in the province of Shandong.
And since then, China has worked to adapt to lessons learned from that project while laying the foundation for a far larger drive to build additional reactors. But China's small modular reactors aren't just meant to enhance Beijing's domestic power supply.
Instead, China openly regards its reactors as a tool of geopolitics and foreign partnership committing to provide those small reactors to partner nations all across the globe.
China's decision is one small part of its worldwide Belt and Road Initiative, in which it's partnered with dozens of participating nations to build infrastructure, extract resources, and engage in other development projects at Beijing's discretion.
China has publicly committed to building and delivering at least 30 small nuclear reactors to Belt and Road partner nations by the year 2030. Nor is China likely to stop there.
Many world nations would love to get their hands on reactors like these, using them to alleviate critical energy shortages, and provide the power required to construct badly needed infrastructure in underdeveloped areas.
For partner nations, China's small modular reactors could fix a whole range of problems at once, especially in parts of Africa, Asia, and Latin America, where the ability to place, say, 100 megawatts of stable, safe, reliable energy anywhere they'd like could dramatically accelerate development, and with it, national prosperity.
Of course, China isn't just choosing to supply partner nations with nuclear reactors out of some sense of charity, though.
I mean, for China, the benefits are geopolitical. Partner nations accept game-changing assistance from Beijing, assume considerable debts, and become reliant on Chinese technology to sustain their progress.
As such, those nations would have considerable incentives to ensure that China sees them as allies and partners, and considerable disincentives against doing anything that might risk pissing China off.
And accepting an entire nuclear reactor isn't exactly a small commitment. Although the specifics of China's reactor deals are currently unknown, they'd most likely involve well-crafted sustainment contracts, exclusivity agreements, and limitations.
For more information, please visit www.fema.gov.au.au. on foreign nations' ability to operate their reactors without supervision.
Except these reactors, and a nation might be agreeing to welcome Chinese technicians and support personnel for many decades in the future, while also agreeing to ensure that those reactors are an irreplaceable source of energy in the regions that they power.
That means that if China were to decide to stop sending support personnel, new fuel, or spare parts because of some diplomatic dispute, those nations would be at risk of watching entire fast-developing regions go dark with no ability to make up the gap.
When China's the only game in town offering the kind of energy infrastructure that can change the future of an entire nation for the better, it can offer those kinds of restrictive terms.
After all, it's a small price to pay if, in exchange for a position in China's orbit, world nations can realize a level of growth and prosperity that would otherwise be impossible. But that sort of geopolitical strategy is only feasible for China, because China is currently projected to hold a near monopoly on small modular reactors.
Turn the clock back to before the announcement of the Janus program, and America's ability to field small nuclear reactors was nothing more than a pipe dream, one that would take years or even decades to realize on American soil and where there were no plans to offer those reactors internationally in direct competition with China.
Whether or not the U.S. recognized the value of what China was doing, and whether or not Washington understood the risk that China would use small modular reactors to bring nations into its sphere of influence almost permanently, the U.S. just didn't have the technology to compete.
Russia can offer comparable products, but at nowhere near the scale that China can, and Moscow is hardly a threat to China's long-term ambitions on the world stage. Europe, India, South Korea, and other potential rivals were very far from becoming truly competitive, leaving China to make the sorts of offers that only a true monopolist can.
Get your reactors from us, or you're never getting reactors at all. And when we said at the outset of today's episode that these initiatives could shape the global balance of power for a century or more, we were not exaggerating.
Small modular reactors can operate for upwards of a decade without the need to refuel, and they're so easy to maintain and operate, especially with the help of outside technicians, that once they're firmly established as a local source of power, they're expected to become very difficult to ever justify replacing.
Cooperation deals signed with China today, either because of short-sightedness, lack of options, or because it genuinely seems like a good idea for a client nation, could establish nuclear power relationships that stretch all the way through to the end of the 21st century, or even further.
Well, enter the Janus Program, an initiative that's intended to bring the U.S. up to speed on miniaturized nuclear technology within the span of just a couple of years. And yeah, right now, the Janus Program comes with a clear, inward-looking focus.
Place nuclear reactors onto army bases and U.S. soil, and perhaps then... extend them to other branches of the U.S. military or other American deployments overseas. But the design of the Janus program, the scope of companies it intends to work with, and its dedication to producing finished products suggest a focus that goes far beyond that initial mission.
As we currently understand it, the Janus program will help nearly a dozen U.S. companies construct, refine, and commercialize nuclear micro-reactors, and by introducing that many potential competitors into the field at once, the U.S. practically guarantees both a certain level of diversity in the end result and a certain level of production capacity that
Would seem to outstrip the demand that the Janus program lays out.
Assuming all the suspected nine participant companies produce a workable commercialized reactor, some of their products will be true micro-reactors, generating 20 megawatts of power or less.
But others are likely to either be bigger from the outset, or at the very least be designed in a way that will allow them to scale up and fill the needs of new customers.
U.S. industry, particularly tech, is expected to help fill the gap, ordering the products that it appreciates most, and giving these companies the time and investment they need in order to iterate and grow their technology.
And if China is able to identify clients to receive 30 small modular reactors across the globe by 2030 alone, then that implies that any U.S. company that can produce its own reactor is going to have substantial incentives to chase relevance on the international market.
Become relevant fast enough, build miniaturized reactors that are capable enough, and the United States stands a chance at breaking China's monopoly before it can even be firmly established.
Investment-rich American companies offering technology trusted by the U.S. military could become players in that international space very quickly, potentially even before their reactor designs move into full-scale commercial production.
The Janus program doesn't call for participating companies to try and challenge China, but it doesn't have to.
For U.S. companies, the value to building small modular reactors and micro-reactors is clear, and by all outward economic indicators, once these companies start to build momentum toward these kinds of reactors, they're going to become powerful new players in the energy and defense sectors.
In order to become competitive with China across the globe on nuclear technology, the United States didn't need a secretive DARPA-style technology program.
It needed to find a way to break through the barriers that lay between U.S. nuclear energy companies and the progress that they already wanted to achieve as soon as possible.
Now, the Janus program has accomplished precisely that, and the global push for nuclear energy is said to become yet another venue for a technological arms race as Washington and Beijing settle in for a new Cold War. Thank you for watching.
