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 ...
A nuclear navy, or nuclear-powered navy, refers to the portion of a navy consisting of naval ships powered by nuclear marine propulsion. The concept was revolutionary for naval warfare when first proposed. Prior to nuclear power, submarines were powered by diesel engines and could only submerge through the use of batteries.
Nuclear-powered civil merchant ships have not developed beyond a few experimental ships. The U.S.-built NS Savannah, completed in 1962, was primarily a demonstration of civil nuclear power and was too small and expensive to operate economically as a merchant ship. The design was too much of a compromise, being neither an efficient freighter nor ...
The Nautilus was the first nuclear-powered submarine. Nautilus put to sea for the first time on 17 January 1955, transmitting the historic message, "Under way on nuclear power." [14] Up until that point, submarines had been torpedo boats tied to the surface by the need to charge their batteries using diesel engines relatively often.
In the 67 years since the Navy launched the world's first nuclear-powered sub, USS Nautilus, its boats have only gotten more capable and more deadly.
All nine of the U.S. Navy nuclear-powered cruisers (CGN) have now been stricken from the Naval Vessel Register, and those not already scrapped by recycling are scheduled to be recycled. While reactor accidents have not sunk any U.S. Navy ships or submarines, two nuclear-powered submarines, USS Thresher and USS Scorpion were lost at
USS Alexandria (SSN-757), is a Los Angeles class nuclear-powered attack submarine and the third vessel of the United States Navy to be named for both Alexandria, Virginia, and Alexandria, Louisiana. [2] The contract to build her was awarded to the Electric Boat Division of General Dynamics Corporation on 26 November 1984.
Yasen-class submarines, also known as Project 885M, are nuclear-powered cruise missile submarines, built to replace Soviet-era nuclear attack submarines as part of a programme to modernise the ...
