A nuclear submarine is a submarine powered by a nuclear reactor, but not necessarily nuclear-armed. Nuclear submarines have considerable performance advantages over "conventional" (typically diesel-electric) submarines. Nuclear propulsion, being completely independent of air, frees the submarine from the need to surface frequently, as is ...
USS. Nautilus. (SSN-571) USS Nautilus (SSN-571) was the world's first operational nuclear-powered submarine and on 3 August 1958 became the first submarine to complete a submerged transit of the North Pole. Her initial commanding officer was Eugene "Dennis" Wilkinson, a widely respected naval officer who set the stage for many of the protocols ...
During the war, 52 US submarines were lost to all causes, with 48 directly due to hostilities; [73] 3,505 [72] [74] sailors were lost, the highest percentage killed in action of any US service arm in World War II. U.S. submarines sank 1,560 enemy vessels, [72] a total tonnage of 5.3 million tons (55% of the total sunk), [75] including 8 ...
A submarine (or sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) [1] The term “submarine” is also sometimes used historically or informally to refer to remotely operated vehicles and robots, or to medium-sized or smaller vessels (such as the midget submarine and the wet sub).
Nuclear weapons. Building on major scientific breakthroughs made during the 1930s, the United Kingdom began the world's first nuclear weapons research project, codenamed Tube Alloys, in 1941, during World War II. The United States, in collaboration with the United Kingdom, initiated the Manhattan Project the following year to build a weapon ...
United States Navy Nuclear Propulsion. The United States Navy Nuclear Propulsion community consists of Naval Officers and Enlisted members who are specially trained to run and maintain the nuclear reactors that power the submarines and aircraft carriers of the United States Navy. Operating more than 80 nuclear-powered ships, the United States ...
Nuclear marine propulsion. When the nuclear-powered Arktika class 50 Let Pobedy was put into service in 2007, it became the world's largest icebreaker. Nuclear marine propulsion is propulsion of a ship or submarine with heat provided by a nuclear reactor. The power plant heats water to produce steam for a turbine used to turn the ship's ...
Armament. 6 × 21-inch (533 mm) torpedo tubes. USS Seawolf (SSN-575) was the third ship of the United States Navy to be named for the seawolf, the second nuclear submarine, and the only US submarine built with a liquid metal cooled (sodium), beryllium - moderated [2][3] nuclear reactor, the S2G. [4] Her overall design (known as SCB 64A) was a ...
