Shkval

The Shkval, 'Squall' in English, is a nuclear-capable underwater anti-ship missile designed for use by nuclear-powered submarines against large surface ships such as aircraft carriers. It comprises a rocket-assisted propeller, which allows a top speed of 220 mph and a maximum range of 6 nautical miles, and a torpedo warhead. The super-cavitating Shkval is considered silent and fast, up to 3-to-4 times over existing torpedoes. The underwater rocket produces a high-pressure stream of bubbles from its nose and skin, which coats the torpedo in a thin layer of gas and forms a local envelope of super-cavitating bubbles achieving low drag. It is not clear whether the lack of a guidance system or, if exists, how it works. Due to its unique characteristics, Shkval is deemed as one of the most advanced naval weapon systems currently deployed worldwide. The torpedo is assembled at the Dastan Torpedo Plant in Kyrgyzstan. In addition to the Russian Navy, the Shkval rocket-assisted torpedo has been sold to India, Iran and Ukraine. In 2008 it was said that Iran may use the Shkval underwater rocket to target the US Navy's aircraft carriers in the Persian Gulf. According to some reports they may use small fast boats as launch platforms. Russia claims that Ukraine sold five brand-new Shkval underwater missiles to Georgia prior to August 2008 conflict. Its development started in times of the Soviet Union (in the 1970s) and was completed by Russia after 2000. This missile system has been pointed out as the source of the fatal accident that shrunken the Russian Navy's Kursk nuclear-powered boat in August 2000. Apparently, the missile was undergoing tests aboard the doomed submarine.
