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 first types developed were the Project 627, NATO-designated November class with two water-cooled reactors, the first of which, K-3 Leninsky Komsomol, was underway under nuclear power in 1958. [18] Nuclear power revolutionized the submarine, finally making it a true "underwater" vessel, rather than a "submersible" craft, which could only ...
The S5W was the standard reactor for submarines of the United States Navy from its first use in 1959 on USS Skipjack until the introduction of the Los Angeles-class submarines with S6G reactor in the mid-1970s. One S5W plant was also used in the United Kingdom on the Royal Navy's first nuclear-powered submarine HMS Dreadnought. [1]
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.
Nuclear-trained Enlisted Sailors perform duties in nuclear propulsion plants operating reactor controls and propulsion and power generation systems. Electrician's Mates (EM) are responsible for the operation of a ship's electrical power generation systems, lighting systems, electrical equipment and electrical appliances. The duties include ...
S = Submarine platform; 1 = First generation core designed by the contractor; B = Bechtel Marine Propulsion Corporation is the contracted designer; This pressurized water nuclear reactor, developed at the Knolls Atomic Power Laboratory, is designed to have increased energy density and to operate for 40 years without refueling.
This naval nuclear reactor is estimated to generate 210 megawatts (MWt) [3] driving a 30 MW pump-jet propulsion system built by BAE Systems that was designed for the Royal Navy [4] and entered service on the second Trafalgar-class submarine, also featured on the Astute-class submarines.
The S1W reactor was the first prototype naval reactor used by the United States Navy to prove that the technology could be used for electricity generation and propulsion on submarines. The designation of "S1W" stands for S = Submarine platform; 1 = First generation core designed by the contractor; W = Westinghouse was the contracted designer
