The Ohio class of nuclear-powered submarines includes the United States Navy's 14 ballistic missile submarines (SSBNs) and its four cruise missile submarines (SSGNs). Each displacing 18,750 tons submerged, the Ohio-class boats are the largest submarines ever built for the U.S. Navy. They are also the third-largest submarines ever built, behind the Russian Navy's Soviet era 48,000-ton Typhoon class, the last of which was retired in 2023, and 24,000-ton Borei class. Capable of carrying 24 Trident II missiles apiece, the Ohio class are equipped with just as many missiles as, if not more than, either the Borei class (16) or the deactivated Typhoon class (20).
General Dynamics Electric Boat (GDEB) is a subsidiary of General Dynamics Corporation. It has been the primary builder of submarines for the United States Navy for more than 100 years. The company's main facilities are a shipyard in Groton, Connecticut, a hull-fabrication and outfitting facility in Quonset Point, Rhode Island, and a design and engineering facility in New London, Connecticut.
USS Louisiana (SSBN-743) is the 18th and last ship of the United States Navy's Ohio class of nuclear-powered fleet ballistic missile submarines. She carries Trident ballistic missiles and has been in commission since 1997. She is the fourth commissioned ship to bear the name of the U.S. state of Louisiana.
USS George Washington (SSBN-598) was the United States's first operational ballistic missile submarine. She was the lead ship of her class of nuclear ballistic missile submarines, was the third United States Navy ship of the name, in honor of Founding Father George Washington (1732–1799), the first president of the United States, and was the first of that name to be purpose-built as a warship.
The George Washington class was a class of nuclear-powered ballistic missile submarines deployed by the United States Navy. George Washington, along with the later Ethan Allen, Lafayette, James Madison, and Benjamin Franklin classes, comprised the "41 for Freedom" group of submarines that represented the Navy's main contribution to the nuclear deterrent force through the late 1980s.
USS Kentucky (SSBN-737) is a United States Navy Ohio-class ballistic missile submarine which has been in commission since 1991. She is the third U.S. Navy ship to be named for Kentucky, the 15th state.
USS Wyoming (SSBN-742) is a United States Navy Ohio-class ballistic missile submarine which has been in commission since 1996. She is the fourth US Navy ship to be named USS Wyoming, although it was only the third named after the state of Wyoming.
USS Casimir Pulaski (SSBN-633), a James Madison-class ballistic missile submarine, was the second ship of the United States Navy to be named for Casimir Pulaski (1745–1779), a Polish general who served in the American Revolutionary War.
USS Columbia (SSN-771) is the 21st flight III, or Improved (688i) Los Angeles-class attack submarine of the United States Navy. Commissioned in 1995, the submarine is assigned to Submarine Squadron 7 and homeported in Joint Base Pearl Harbor-Hickam.
The upcoming Columbia-class nuclear-powered ballistic missile submarines of the United States Navy are designed to replace the Ohio class. Construction of the first vessel began on 1 October 2020. She is scheduled to enter service in 2031.
USS District of Columbia (SSBN-826) will be the lead boat of the United States Navy's Columbia-class ballistic missile submarines and the Navy's first vessel to be named for the District of Columbia.
The Constellation-class multi-mission guided-missile frigates of the United States Navy are based on the European multipurpose frigates (FREMM), already in service with the French and Italian navies. Constellation follows the modular but problematic littoral combat ships of the Freedom and Independence classes. The U.S. Navy announced the FFG(X) frigate project in the United States Department of Defense's Request For Information (RFI) in July 2017.
USS Wisconsin (SSBN-827) will be the second Columbia-class ballistic missile submarine. She is the third vessel of the United States Navy to be named after the state of Wisconsin. The previous name holder was the Iowa-class battleship USS Wisconsin (BB-64), which decommissioned in 1991 and stricken from the Naval Vessel Register in 2006.
USS John H. Dalton (SSN-808) will be a nuclear-powered Virginia-class submarine for the United States Navy, the seventh of the Block V attack submarines and 35th overall of the class. She will be the first U.S. Naval vessel named for John Howard Dalton, the 70th Secretary of the Navy and a former submariner who, after graduating with distinction from the U.S. Naval Academy in 1964, served aboard the attack submarine USS Blueback (SS-581) and the ballistic missile submarine USS John C. Calhoun (SSBN-630).
USS Potomac (SSN-814) will be a nuclear-powered Virginia-class submarine of the United States Navy, the first Block VI attack submarines and 41st overall of her class.
USS Norfolk (SSN-815) will be a nuclear-powered Virginia-class submarine of the United States Navy, the second Block VI attack submarines and 42nd overall of her class. She will be the fourth US Navy ship to bear the name Norfolk, the name previously belonged to a Los Angeles-class submarine.
USS Brooklyn (SSN-816) will be a nuclear-powered Virginia-class submarine of the United States Navy, the third Block VI attack submarines and 43rd overall of her class.
