Torpedo (weapon) | Oi Torpedo | Submarines Weapon | Torpedo SubmarinesTorpedo (weapon) | Oi Torpedo | Submarines Weapon | Torpedo Submarines Torpedo (weapon), self-propelled underwater naval weapon with an explosive charge, equipped with an internal-guidance system that controls its direction, speed, and depth. A typical torpedo is cigar-shaped, is 6 m (21 ft) long, has a diameter of 53 cm (21 in), and weighs about 1361 kg (about 3000 lb). Torpedoes are the principal weapons of the submarine; during World War II (1939-1945), torpedoes were also the principal weapons of the PT boat. In addition, torpedoes are used by antisubmarine surface vessels and airplanes. Torpedo (weapon) | Oi Torpedo | Submarines Weapon | Torpedo Submarines Modern torpedoes are classified as steam torpedoes or electric torpedoes. Steam torpedoes have speeds from 25 to 45 knots and ranges from 4367 to 27,350 m (4000 to 25,000 yd). Their four major components are the warhead, air-flask section, afterbody section, and tail section. The warhead is filled with 181 to 363 kg (400 to 800 lb) of explosives. The air-flask section constitutes about one-third of the torpedo and contains compressed air and fuel and water tanks for the propulsion system. The afterbody section contains the propulsion turbines and the steering and depth-control devices. The tail section contains the rudders, exhaust valves, and propellers. Controls of the electric torpedo are similar to those of steam torpedoes, except that the large air flask is replaced by storage batteries and the turbines are replaced by an electric motor. Because electric torpedoes are more difficult to detect than steam torpedoes, more and more torpedoes today are electrically powered.
