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 first sea-based missile deterrent forces were a small number of conventionally powered cruise missile submarines and surface ships fielded by the United States and the Soviet Union in the 1950s, deploying the Regulus I missile and the Soviet P-5 Pyatyorka (also known by its NATO reporting name SS-N-3 Shaddock), both land attack cruise missiles that could be launched from surfaced submarines.
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]
USS Ohio (SSBN-726/SSGN-726), the lead boat of her class of nuclear-powered fleet ballistic missile submarines (SSBN), is the fourth vessel of the United States Navy to be named for the U.S. state of Ohio. She was commissioned with the hull designation of SSBN-726, and with her conversion to a guided missile submarine she was re-designated SSGN ...
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. Attack submarines have several tactical missions, including sinking ships and subs, launching cruise missiles, and gathering intelligence. Cruise missile ...
The United States had deployed nuclear weapons aboard submarines for the purpose of deterrence since 1959, using the SSM-N-8 Regulus cruise missile.However, this was intended to act merely as a stop-gap, as the Regulus was limited both by its size – the greatest number of missiles capable of being taken to sea was five aboard USS Halibut – range and speed, as well as the fact that the ...
Maryland is the 13th of the 18 Ohio-class ballistic missile submarines, and has been in active service since 1992. Maryland is the fourth US Navy vessel to be named after the US state of Maryland . Her mission is to provide the United States government with an undetectable and unattackable nuclear launch platform in support of the national ...
