The Los Angeles class of submarines are nuclear-powered fast attack submarines (SSN) in service with the United States Navy. Also known as the 688 class after the hull number of lead vessel USS Los Angeles (SSN-688), 62 were built from 1972 to 1996, the latter 23 to an improved 688i standard. As of 2022, 26 of the Los Angeles class remain in commission — more than any other class in the world — and they account for more than half of the U.S. Navy's 50 fast attack submarines.
The Sturgeon class was a class of nuclear-powered fast attack submarines (SSN) in service with the United States Navy from the 1960s until 2004. They were the "workhorses" of the Navy's attack submarine fleet throughout much of the Cold War. The boats were phased out in the 1990s and early 21st century, as their successors, the Los Angeles, followed by the Seawolf and Virginia-class boats, entered service.
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. A fleet of 29 submarines was to be built over a ten-year period, but that was reduced to 12 submarines. The end of the Cold War and budget constraints led to the cancellation of any further additions to the fleet in 1995, leaving the Seawolf class limited to just three boats. This, in turn, led to the design of the smaller Virginia class. The Seawolf class cost about $3 billion per unit, making it the most expensive United States Navy fast attack submarine and second most expensive submarine ever, after the French Triomphant-class nuclear-powered ballistic missile submarines.
The Virginia class, also known as the SSN-774 class, is a class of nuclear-powered cruise missile fast-attack submarines, in service in the United States Navy. Designed by General Dynamics Electric Boat (EB) and Huntington Ingalls Industries, the Virginia class is the United States Navy's latest submarine model, which incorporates the latest in stealth, intelligence gathering, and weapons systems technology.
USS Thresher (SSN-593) was the lead boat of her class of nuclear-powered attack submarines in the United States Navy. She was the U.S. Navy's second submarine to be named after the thresher shark.
USS Virginia (CGN-38) was a nuclear-powered guided missile cruiser, the lead ship of her class, and the eighth ship of the United States Navy to be named for the Commonwealth of Virginia. She was commissioned in 1976 and decommissioned in 1994.
USS Seawolf (SSN-575) was the third ship of the United States Navy to be named for the seawolf, the second nuclear submarine, and the only US submarine built with a liquid metal cooled (sodium), beryllium-moderated nuclear reactor, the S2G. Her overall design was a variant of Nautilus, but with numerous detail changes, such as a conning tower, stepped sail, and the BQR-4 passive sonar mounted in the top portion of the bow instead of further below. This sonar arrangement resulted in an unusual bow shape above the water for a U.S. submarine. Her distinctive reactor was later replaced with a standard pressurized water reactor, the replacement process lasting from 12 December 1958 to 30 September 1960.
USS Minneapolis–Saint Paul (SSN-708), a Los Angeles-class submarine, was the first vessel of the United States Navy to be named for the metropolitan area of Minneapolis-Saint Paul, Minnesota, although each city had been honored twice before. The contract to build her was awarded to the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut on 31 October 1973 and her keel was laid down on 20 January 1981. She was launched on 19 March 1983 sponsored by Mrs. Penny Durenberger, and commissioned on 10 March 1984, with Commander Ralph Schlichter in command.
USS Augusta (SSN-710), a Los Angeles-class submarine, was the first ship of the United States Navy to be named for Augusta, Maine. The contract to build her was awarded to the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut on 31 October 1973 and her keel was laid down on 1 April 1983. She was launched on 21 January 1984 sponsored by Mrs. Diana D. Cohen, wife of U.S. Senator William Cohen and commissioned on 19 January 1985.
USS Pogy (SSN-647), a Sturgeon-class submarine, was the second ship of the United States Navy to be named for the pogy, or menhaden.
USS Halibut (SSGN-587), a unique nuclear-powered guided missile submarine-turned-special operations platform, later redesignated as an attack submarine SSN-587, was the second ship of the United States Navy to be named after the halibut.
USS Scorpion (SSN-589) was a Skipjack-class nuclear-powered submarine that served in the United States Navy, and the sixth vessel, and second submarine, of the U.S. Navy to carry that name.
USS Baton Rouge (SSN-689) was a Los Angeles-class nuclear-powered attack submarine which served with the United States Navy. With her keel laid down on 18 November 1972, Baton Rouge was launched on 26 April 1975. She became the second Los Angeles-class submarine to be commissioned, on 25 June 1977. In 1995, she was the first of her class to be decommissioned, after a collision with a Russian Sierra-class submarine.
USS Louisville (SSN-724), a Los Angeles-class submarine, is the fourth ship of the United States Navy to be named for Louisville, Kentucky. The contract to build her was awarded to the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut, on 11 February 1982 and her keel was laid on 24 September 1984. She was launched on 14 December 1985—sponsored by Mrs. Betty Ann McKee, wife of Admiral Kinnaird McKee, Director of Naval Nuclear Propulsion —and commissioned on 8 November 1986 with Captain Charles E. Ellis in command.
USS Cheyenne (SSN-773), the final Los Angeles-class submarine, is the third ship of the United States Navy to be named for Cheyenne, Wyoming. The contract to build her was awarded to Newport News Shipbuilding and Dry Dock Company in Newport News, Virginia on 28 November 1989 and her keel was laid down on 6 July 1992. She was launched on 16 April 1995 sponsored by Mrs. Ann Simpson, wife of Wyoming Senator Alan K. Simpson, and commissioned on 13 September 1996, with Commander Peter H. Ozimik in command. Cheyenne transferred to her homeport of Pearl Harbor, Hawaii, in 1998.
A nuclear submarine is a submarine powered by a nuclear reactor, but not necessarily nuclear-armed. Nuclear submarines have considerable performance advantages over "conventional" submarines. Nuclear propulsion, being completely independent of air, frees the submarine from the need to surface frequently, as is necessary for conventional submarines. The large amount of power generated by a nuclear reactor allows nuclear submarines to operate at high speed for long periods, and the long interval between refuelings grants a range virtually unlimited, making the only limits on voyage times being imposed by such factors as the need to restock food or other consumables.
USS Atlanta (SSN-712), a Los Angeles-class submarine, was the fifth ship of the United States Navy to be named for Atlanta, Georgia. The contract to build her was awarded to Newport News Shipbuilding and Dry Dock Company in Newport News, Virginia, on 1 August 1975 and her keel was laid down on 17 August 1978. She was launched on 16 August 1980 sponsored by Mrs. Sam Nunn, and commissioned on 6 March 1982, with Commander Robin J. White in command.
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. Attack submarines have several tactical missions, including sinking ships and subs, launching cruise missiles, and gathering intelligence. Cruise missile submarines perform many of the same missions as attack submarines, but with a focus on their ability to carry and launch larger quantities of cruise missiles than typical attack submarines.
Tom Clancy's SSN is a submarine simulator of the 688i. The game player is in command of USS Cheyenne in a limited war against China over the Spratly Islands. Gameplay is limited to a 15 mission single-player campaign in which the player carries out anti-submarine, anti-surface ship roles, intelligence gathering activities, and the launch of submarine based cruise missiles. Tom Clancy also wrote a book by the same name as a tie-in.
