A report on a Chinese “nuclear-powered tank” concept became a hot topic on a 5channel (5ch) Science News+ thread. [5ch is Japan’s largest anonymous forum network, the successor to 2channel.] The idea is a tank powered by a nuclear reactor and armed with a cannon that has a 450km range, but the thread quickly filled with pushback — pointing out that the Soviet Union researched something similar decades ago, so it wouldn’t be a “world first,” plus a string of technical questions about cooling methods, radioactive contamination if the vehicle is hit, and the risk of being taken out cheaply by drones. The discussion eventually broadened into a debate over whether giant weapons are simply obsolete, using the WWII battleship Yamato as a reference point.
China dreams of the world’s first “nuclear-powered tank”… to be armed with a cannon with a 450km range
Could a nuclear-powered tank actually be built?
That’s the concept now emerging in China.

Even with the naval treaty limits of the era, every major navy kept building battleships. Among them, the Yamato class was an outstanding weapon riding the cutting edge of that era's trends.
By a quirk of fate it never got the chance to fire on an enemy battleship (the US Navy actually dispatched battleship task forces twice to try to intercept it), but its armor proved tougher than even the design called for.
Most follow-on programs never got finished for economic reasons, but the fact that the major naval powers kept building battleships even after the war validates the Yamato's existence.
Aircraft only became the true all-purpose weapon some time after the war, once jet range improved dramatically.
If you want to call something 'outdated,' consider this: the Yamato class went to considerable lengths to shorten its overall length just to reduce the chance of being hit. By contrast, the US Navy's final battleship design, the Montana class — meant as the culmination of American battleship design — dropped the Panama Canal size restrictions entirely and had a far more sprawling hull. That long hull is thought to have become a serious liability when facing air attack.
[A] Not at all. Japan commissioned only two battleships during the war — Yamato and Musashi. The US Navy commissioned a full eight.

Sure, sure, uh-huh… good luck with that.
It shows up right at the start of Ace Combat 8, doesn't it? A land battleship.
Background and Key Points of the Discussion
The source for this story is a report out of China about a “nuclear-powered tank” concept — worth noting that this is still a proposed idea, not a fielded weapon. A nuclear-powered tank isn’t itself a new idea: the former Soviet Union is on record researching nuclear-powered tank concepts during the Cold War, which is why several commenters pushed back on the “world’s first” framing. Nuclear aircraft carriers and submarines work because they can be cooled with seawater; a land-based tank has no equivalent cooling method, so how to handle the risk of scattering radioactive material if the vehicle is hit or destroyed becomes the single biggest technical hurdle. The “450km range” figure also drew geopolitical readings, with several posters noting it lines up suspiciously well with distances across the Taiwan Strait or the Korean Peninsula — showing the discussion wasn’t purely about hardware. Meanwhile, the exchange invoking the WWII battleship Yamato turned into a surprisingly detailed historical back-and-forth, extending the debate into a broader question: in the age of drone warfare, are giant weapons platforms simply obsolete?
