A cavitation forms behind an object passed by a rapidly streaming liquid
In 1940 the German company Henschel developed the first projectile to use supercavitation: the Henschel Hs 293 C. In 1977, Soviet engineers developed the VA-111 Shkval ('Squall') torpedo. This can travel at 230 mph (100 m/s) underwater, compared to the top speed of about 80 mph (35 m/s) for conventional aquatic craft, but it is reportedly not steerable. Even faster speeds of about 310 mph (ca. 140 m/s) and higher have also been rumored. News of the device reached the West in the 1990s.
The Naval Undersea Warfare Center in Newport, Rhode Island, USA is now also working on the phenomenon."
