China Claims to Have Developed a Radical New Stealth Technology for Its Submarines

China Claims to Have Developed a Radical New Stealth Technology for Its SubmarinesUnlike a conventional propulsor design—which is turned by a mechanical drive shaft—China’s rim-driven system is powered by an electrical motor embedded in the propulsor’s shroud. Thus, if the Chinese have managed to successfully develop a rim-driven pumpjet propulsor that works in a real world operational setting, it would be a significant development. It would mean that the PLAN is making genuine progress in developing novel submarine technologies and that it is starting to catch up.
