## Overview Chinese military researchers have outlined a conceptual plan for a nuclear-powered main battle tank armed with an electromagnetic railgun capable of striking targets up to 450km (280 miles) away, potentially debuting after 2045 (SCMP, September 15, 2026). ## Technical Details The concept, detailed in a peer-reviewed paper published in June in the Chinese journal Acta Armamentarii, envisions a 60-tonne armoured vehicle powered by a 10-megawatt-class small modular reactor (SMR) and equipped with a 50-megajoule (MJ) railgun (SCMP, September 15, 2026). ## Strategic Significance While this remains a long-term research concept rather than an active program, it reflects China's continued investment in next-generation weapons research spanning nuclear miniaturization, directed-energy and electromagnetic weapons, and advanced armor systems. It parallels other Chinese military technology programs including hypersonic weapons research and laser-equipped combat vehicles. ## What to Watch - Follow-on research publications detailing progress toward prototype development - Comparisons with other advanced armor and railgun programs globally - Potential defense budget allocations tied to next-generation ground combat systems
