Submarines could usually locate and attack other submarines only on the surface, although HMS Venturer managed to sink U-864 with a four torpedo spread while both were submerged. The British developed a specialized anti-submarine submarine in WWI, the R class. After WWII, with the development of the homing torpedo, better sonar systems, and nuclear propulsion, submarines also became able to hunt each other effectively.
The year 2000 marks the 100th anniversary of the U. S. Navy's submarine force. Today's attack submarine is one of the most lethal weapons in the nation's arsenal, and the ballistic missile submarine constitutes a very important component of the country's strategic deterrent. The original stealth weapon, the submarine cruises the world's oceans unseen, carrying out a variety of missions.
Submarines are essentially containers that hold people and air. Learn how these remarkable vessels dive, surface and maneuver through the ocean.
Since the year 2000 there have been 9 major naval incidents involving submarines. There were three Russian submarine incidents, in two of which the submarines in question were lost, along with three United States submarine incidents, one Chinese incident, one Canadian, and one Australian incident. In August 2005, the Russian PRIZ, an AS-28 rescue submarine was trapped by cables and/or nets off of Petropavlovsk, and saved when a British ROV cut them free in a massive international effort.

A nuclear submarine is a submarine powered by a nuclear reactor. The performance advantages of nuclear submarines over "conventional" (typically diesel-electric) submarines are considerable. Nuclear propulsion, being completely independent of air, frees the submarine from the need to surface frequently, as is necessary for conventional submarines. The large amount of power generated by a nuclear reactor allows nuclear submarines to operate at high speed for long periods of time; and the long interval between refuelings grants a range limited only by consumables such as food.
America's Navy uses fast attack, ballistic missile, guided missile, & special rescue submarines in its "Silent Service". Learn more about Naval submarines.
