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 ...
Toggle Current nuclear submarine classes subsection. 1.1 China. 1.1.1 Nuclear-powered attack submarines. 1.1.2 Nuclear-powered ballistic missile submarines.
The submarine was launched on 27 August 1983, sponsored by his second wife Eleonore, commissioned on 21 July 1984, and deactivated on 14 December 2006. In 2015, the Navy announced a Virginia-class submarine named USS Hyman G. Rickover (SSN-795) in his honor. [117] The submarine's christening took place on 31 July 2021. [118] [119] [120] [121]
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.
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).
The Soviet submarine K-129 carried nuclear ballistic missiles when it was lost with all hands, but as it was a diesel-electric submarine, it is not included in the list. (K-129 was partly recovered by the U.S. Project Azorian.) The two USN submarines belonged to Submarine Force Atlantic, in the U.S. Atlantic Fleet.
There are three major types of submarines in the United States Navy: ballistic missile submarines, attack submarines, and cruise missile submarines. All submarines currently in the U.S. Navy are nuclear-powered. Ballistic missile submarines have a single strategic mission of carrying nuclear submarine-launched ballistic missiles.
The NR-1 Deep Submergence Craft was a non-commissioned nuclear submarine operated by the United States Navy. Turtle, an American submarine of the American Revolutionary War; H. L. Hunley, a human-powered submarine of the American Civil War in the early 1860s, operated by the Confederate States Army.
