The fastest torpedo is Russia's Shkval (or Squall), initially revealed in 1995 and developed by the Moscow Sergo Ordzhonikidze Aviation Institute, Russia. This rocket-propelled reaches a top-speed of approximately 230 mph (100 m/sec) with an estimated range of 6.8 km (4.2 miles).This makes it three to four times faster than regular torpedos.Other conversions of speed: 360 kph, 200-knots. It measures 533 mm (2 in) diameter and 8.23 m (27 ft) long. This missile is pilot-guided rather than having a homing device. It is able to reach such speeds due to the release of high-pressure bubbles which coats the torpedo in an envelope of water vapour and ultimately reduces the friction on the missile.
