China mulls building nuclear-powered tank with 450km-range railgun in 2 decades

Chinese military researchers have outlined an ambitious plan to develop a nuclear-powered main battle tank armed with an electromagnetic railgun capable of hitting targets up to 450km (280 miles) away, possibly debuting after 2045.
Detailed in a peer-reviewed paper published in June in the Chinese journal Acta Armamentarii, the concept envisions a 60-tonne armoured vehicle driven by a 10-megawatt-class small modular reactor (SMR) and a 50-megajoule (MJ) railgun.
