Summary

China is considering developing a nuclear-powered tank equipped with a 450km-range railgun, according to a peer-reviewed paper published in June by Acta Armamentarii. This proposed vehicle would weigh about 60 tonnes and be powered by a 10-megawatt-class small modular reactor, while the railgun is projected to deliver a force of 50 megajoules. The project has received funding from China's National Key Laboratory of Special Vehicle Design and Manufacturing Integration Technology, but further simulations and tests are needed before practical deployment can be considered.

Story summary

A peer-reviewed paper published in June in Acta Armamentarii by researchers at the National Key Laboratory of Special Vehicle Design and Manufacturing Integration Technology proposes a concept for a nuclear-powered tank capable of firing a railgun with a range of up to 450 kilometers. The vehicle would weigh 60 tonnes, be powered by a 10-megawatt-class small modular reactor (SMR), and feature a 50-megajoule railgun. While the concept is detailed in this paper, further multi-physics simulations and vehicle-level testing are required before these systems could move towards practical deployment. The study was funded by a special research project at the laboratory.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.
