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).
A submarine (or sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) [2] The term “submarine” is also sometimes used historically or informally to refer to remotely operated vehicles and robots, or to medium-sized or smaller vessels (such as the midget submarine and the wet sub).
Size comparison of common World War II submarines with the Typhoon class Soviet Typhoon-class ballistic missile submarine, with inset of an American football field graphic to convey a sense of the enormous size of the vessel. The Typhoon class was developed under Project 941 as the Soviet Akula class (Акула), meaning shark.
A midget submarine is any submarine under 150 tons, [1] typically operated by a crew of one or two but sometimes up to six or nine, with little or no on-board living accommodation. They normally work with mother ships , from which they are launched and recovered and which provide living accommodation for the crew and support staff.
Prototype "fleet submarines"—submarines fast enough (21 knots (11 m/s)) to travel with battleships. Twice the size of any concurrent or past U.S. submarine. A poor tandem engine design caused the boats to be decommissioned by 1923 and scrapped in 1930.

The Seawolf class is a class of nuclear-powered, fast attack submarines (SSN) in service with the United States Navy. The class was the intended successor to the Los Angeles class, and design work began in 1983. [10] A fleet of 29 submarines was to be built over a ten-year period, but that was reduced to 12 submarines.
To get the submarine's price down to $2 billion per submarine in FY-05 dollars, the Navy instituted a cost-reduction program to shave off approximately $400 million of each submarine's price tag. The project was dubbed "2 for 4 in 12", referring to the Navy's desire to buy two boats for $4 billion in FY-12.
