Ever since Eraser, everyone wants a railgun. Turns out China is no exception. Some photos posted by Dafeng Cao, a Twitter user who keeps close tabs on Chinese military developments, show a ship-mounted gun that could very well be the country's very own homegrown electromagnetically propelled mass driver.
Railguns, or coil guns, accelerate solid metal projectiles using ultra-strong electromagnets, firing them well above speeds achieved by conventional ballistic methods. We're talking Mach 6 here. The U.S. has been working on them for years, and has produced some very cool test videos, but I haven't heard about any of them being mounted on ships.
