A nuclear submarine is a submarine powered by a nuclear reactor, but not necessarily nuclear-armed.In the US classification, nuclear-powered submarines are designated as SSxN, where the SS denotes submarine, x=G means that the submarine is equipped with guided missiles (usually cruise missiles), x=B means that the submarine is equipped with ballistic missiles (usually intercontinental) and the ...
The name S9G follows the designation scheme of platform type (submarines), generation (the ninth), and the contractor (General Electric). This pressurized water reactor (PWR), developed by Knolls Atomic Power Laboratory (managed by General Electric), features increased energy density , and new plant components, including a new steam generator ...
Nuclear power revolutionized the submarine, finally making it a true "underwater" vessel, rather than a "submersible" craft, which could only stay underwater for limited periods. It gave the submarine the ability to operate submerged at high speeds, comparable to those of surface vessels, for unlimited periods, dependent only on the endurance ...
By 1962, the US Navy had 26 nuclear submarines operational and 30 under construction. Nuclear power had revolutionized the U.S. Navy. The technology was shared with the United Kingdom, while technological development in France, China and the Soviet Union proceeded separately.
The US Navy has a total of 18 Ohio-class submarines which consist of 14 ballistic missile submarines (SSBNs), and four cruise missile submarines (SSGNs). The SSBN submarines provide the sea-based leg of the U.S. nuclear triad. Each SSBN submarine is armed with up to 20 Trident II submarine-launched ballistic missiles (SLBM).
Bettis Atomic Power Laboratory, operated by Westinghouse, developed the basic reactor plant design used in Nautilus after being given the assignment on 31 December 1947 to design a nuclear power plant for a submarine. [14] Nuclear power had a crucial advantage in submarine propulsion because it is a zero-emission process that consumes no air.
This nuclear reactor was designed by General Electric for use on the Los Angeles-class attack submarines.The S6G reactor plant consists of the reactor coolant, steam generation, and other support systems that supply steam to the engine room.
