Chinese military researchers have proposed a nuclear-powered main battle tank armed with an electromagnetic railgun capable of striking targets up to 450 kilometres (280 miles) away, in a concept that could debut after 2045. The proposal, detailed in a peer-reviewed paper published in June 2026 in the Chinese defence journal Acta Armamentarii, represents one of the most ambitious armoured-vehicle concepts to emerge from China's state-linked research ecosystem.

What the researchers are proposing

The concept envisions a 60-tonne armoured vehicle powered by a 10-megawatt-class small modular reactor (SMR) and equipped with a 50-megajoule (MJ) electromagnetic railgun. The railgun's 450km range would dwarf the effective range of any conventional tank gun currently in service globally, effectively repositioning the platform from a close-combat weapon to a long-range precision strike system. The paper was authored by researchers from Inner Mongolia First Machinery Group — a cornerstone of China's defence industrial system closely associated with tank and armoured vehicle development — and the Beijing Institute of Technology. The study was funded by the National Key Laboratory of Special Vehicle Design and Manufacturing Integration Technology through a dedicated research project.

Why it matters

The integration of a small modular reactor into a ground combat vehicle would solve the energy problem that has historically limited railgun development. Conventional electromagnetic railguns require enormous bursts of electrical power that battlefield generators or battery packs struggle to sustain. A 10-megawatt-class SMR could theoretically provide continuous high-energy firing cycles, making the weapon operationally viable rather than a laboratory curiosity. The 50MJ muzzle energy figure is also significant: for context, the US Navy's experimental railgun programme, now largely shelved, targeted around 32MJ. A 50MJ system would deliver substantially greater projectile velocity and range.

The competitive backdrop

The proposal arrives as major military powers reassess the future of armoured warfare following lessons from the Russia-Ukraine conflict, where tanks have proven vulnerable to drone strikes and anti-tank guided missiles. Rather than abandoning the platform, Chinese researchers appear to be betting on a radical capability leap — long-range standoff firepower — to keep the main battle tank relevant through mid-century. Inner Mongolia First Machinery Group is the manufacturer behind China's existing Type 99A and Type 15 tank families, lending the research institution credibility beyond pure academic speculation.

What's next

The researchers acknowledge a post-2045 timeline, signalling that the concept remains in early-stage theoretical development. Key engineering hurdles — miniaturising a safe, battlefield-hardened SMR, managing heat dissipation in an enclosed armoured hull, and developing railgun barrel materials that can withstand repeated high-energy firings — remain unsolved at scale. Whether the concept transitions from peer-reviewed paper to a funded prototype programme will depend on China's broader defence budget priorities and progress in civilian SMR technology, where Beijing is already among the world's most active investors. Observers will watch for follow-on funding announcements and whether the concept surfaces in official People's Liberation Army procurement documents in the years ahead.
