The upcoming Columbia-class (formerly known as the Ohio Replacement Submarine and SSBN-X Future Follow-on Submarine) nuclear-powered ballistic missile submarines of the United States Navy are designed to replace the Ohio class. [7] Construction of the first vessel began on 1 October 2020. [8] She is scheduled to enter service in 2031. [9] [10] [11]
Cutaway drawing of a proposed nuclear-powered radar picket submarine, c. 1954 Design work on a nuclear-powered radar picket submarine (SSRN) began in 1954–1955. [ 17 ] As initially designed, Triton had a three-level hull, with the Combat Information Center (CIC) ( see image ) located on the middle level. [ 17 ]
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 ...
The Virginia class, or the SSN-774 class, is the newest class of nuclear-powered cruise missile fast attack submarines in service with the United States Navy.The class is designed for a broad spectrum of open-ocean and littoral missions, including anti-submarine warfare and intelligence gathering operations. [10]
Submarines of this class are named after American towns and cities, such as Albany, New York; Los Angeles, California; and Tucson, Arizona, with the exception of USS Hyman G. Rickover, named for the "father of the nuclear Navy." This was a change from traditionally naming attack submarines after marine animals, such as USS Seawolf or USS Shark ...
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.
USS Skate (SSN-578) was the third submarine of the United States Navy named for the skate, a type of ray, was the lead ship of the Skate class of nuclear submarines.She was the third nuclear submarine commissioned, the first to make a completely submerged trans-Atlantic crossing, the second submarine to reach the North Pole, and the first to surface there.
