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]

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.
Later designs, notably those of the US Fleet submarines and German U-boats, placed two separate ballast tanks lower down on the sides of the hull (diagram C). In railway practice this would have been a "pannier tank", but for submarines the "saddle" label remained. [note 1]
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.

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).
U.S. Navy diagram of a Type XXI U-boat. Note the teardrop-shaped fairing for the large hydrophone array beneath the bow and the wasp-waist pressure hull. The large sonar array and its housing did slow the boat down, but its placement and size allowed for a very sensitive system to be installed, and gave it near-360 degree coverage around the ...
USS Albacore was a unique research submarine that pioneered the American version of the teardrop hull form (sometimes referred to as an "Albacore hull") of modern submarines. On modern military submarines the outer hull (and sometimes also the propeller) is covered with a thick layer of special sound-absorbing rubber, or anechoic plating , to ...
