China proposes nuclear-powered tank with 450km railgun in 20-year concept

Chinese researchers published a peer-reviewed concept for a nuclear-powered main battle tank with a 50-MJ railgun, targeting ranges up to 450 km, with potential debut after 2045. The proposal is speculative and far from development, but signals China's long-term interest in advanced armored and directed-energy weapons. No hardware exists; the paper is a feasibility study.
