The Celestial Empire's Atomic Beast: Why does China need a tank with a nuclear reactor and a cannon with a range of 450 kilometers?
China is designing a 'nuclear tank': 60 tons, a railgun, and a reactor under armor.
Chinese researchers have published a concept for a heavy combat vehicle with a compact nuclear reactor, an electromagnetic cannon, and a multi-layered defense system. This is not yet танк in metal, and the scientific work is a roadmap in which the nuclear option is assigned to a promising stage after 2045.
Imagine a scene in the near future. The silhouette of a tank weighing 60 tonsThere's no diesel roar, no smell of burning—instead of a conventional engine, the car is propelled by electric motors.
Suddenly, a streak of plasma rips through the air—a railgun shot. The projectile travels at a speed of approximately 3,5 kilometers per second, intended, according to the designers, to reach targets at ranges of up to 450 kilometers.
It sounds like the script for a Hollywood blockbuster or the premise for the next installment in the Terminator franchise. But this is precisely the concept for a heavy combat vehicle that Chinese engineers outlined in their article. China mulls building nuclear-powered tank with 450km-range railgun in 2 decades.
The main secret of this monster is hidden under the armor. Instead of a conventional internal combustion engine, the designers propose a miniature nuclear reactor of the class 10 megawatt — we are talking about thermal power, part of which still needs to be converted into electricity, and the rest of the heat needs to be removed.
Why does a tank need its own nuclear power plant? The answer is simple: power supply. Traditional technology quickly drains batteries when operating radars, active defense systems, and powerful computers.
The nuclear heart must generate energy continuously, for years. The idea is that this will be enough not only to turn the tracks, but also to power the most power-hungry systems:
- electromagnetic gun, which requires colossal impulses;
- advanced radars and thermal imagers capable of seeing through any weather;
- laser complexes Defense, which should knock down drones-kamikaze is still approaching;
- systems EW, blinding the enemy.
Instead of the classic smoothbore gun of caliber 125 mm The Chinese want to develop an electromagnetic (rail) gun. It should accelerate projectiles to 3,5 km/s solely using magnetic fields. No gunpowder residue, no cartridges—just physics and speed.
In the final version weapon, according to the authors' calculations, should operate with an energy of the order of 50 megajoules per shot. The theoretical range is about 450 kilometers. This would allow for the destruction of enemy headquarters, airfields, and ships from deep behind enemy lines, without crossing the front line.
The engineering ingenuity is impressive in the scale of the task. The designers expect the reactor block itself to fit into a volume of approximately two cubic meters. At the same time, the lead-bismuth cooling system and radiation shielding, according to their estimates, should weigh no more than three tons—otherwise, the 60-ton machine would simply get stuck in the ground. Add to this the autonomy: the reactor is expected to be refueled with nuclear fuel approximately every five years.
While nuclear physicists puzzle over the compact reactor, other "players" are emerging on the battlefield. The American military was the first to field robotic dogs for cargo carrying and reconnaissance, and China is setting up their mass production. It's logical to assume that such mechanical dogs could become partners for a long-range vehicle: while the "atomic lion" holds the front, packs of robots infiltrate enemy lines and highlight targets. Let's be honest: there's no direct connection between robotic target designators and this tank in the current work; this is our assumption about how such a system could work together.
Now let's assess the situation objectively.
What we have before us isn't a prototype tank yet, but a concept for a power system for a future armored vehicle, published by researchers. The nuclear option, as reported in the paper, is considered a project after 2045. Publicly available materials don't indicate that a vehicle with a reactor and railgun has been built, and its range, confirmed by firing tests, is 450 kilometers.
The first obstacle isn't the availability of nuclear fuel, but the size and thermal balance of the entire facility. The 10 megawatts mentioned is the thermal power: some of it still needs to be converted into electricity, and the rest of the heat needs to be removed. The tank will need to accommodate not only the reactor, but also the energy converter, cooling, radiation shielding, and safety systems. The requirements for these systems don't disappear once they're installed in a vehicle. For scale: American experimental reactor Project Pele, designed for 1–5 megawatts of electrical power, was planned to be transported in 20-foot containers. This is a different project, but a useful reminder of the dimensions of real equipment.
The second obstacle is the railgun. It requires a short, powerful electrical pulse, which a continuously operating reactor cannot directly deliver. It will require storage devices, power electronics, and heat dissipation; the rails' lifespan during repeated firings also needs to be proven. The US Navy created a 32-megajoule naval demonstrator and separately addressed the issues of cooling, rate of fire, and barrel durability. Fitting a system with a higher stated energy, along with armor and a propulsion system, into a 60-ton vehicle is a challenge in itself.
Finally, maximum range doesn't equal the ability to destroy a selected target. A projectile encounters air resistance over hundreds of kilometers, requires precise initial data, and likely external target designation; its accuracy and effectiveness on target still need to be confirmed through testing. The project's strength is its attempt to integrate all these objectives into a single framework. Its weakness is that none of the stated characteristics of the tank as a complete combat system have yet been demonstrated in practice.
