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. Design work began in 1983. At one time, an intended fleet of 29 submarines was to be built over a ten-year period, later reduced to twelve submarines. The end of the Cold War and budget constraints led to the cancellation in 1995 of any further additions to the fleet, leaving the Seawolf class limited to just three boats. This, in turn, led to the design of the smaller Virginia class.
Submarines of the United States Navy are built in classes, using a single design for a number of boats. Minor variations occur as improvements are incorporated into the design, so later boats of a class may be more capable than earlier. Also, boats are modified, sometimes extensively, while in service, creating departures from the class standard.
USS Jimmy Carter (SSN-23) is the third and last Seawolf-class submarine in the United States Navy. She is the first ship in the U.S. Navy to be named for Jimmy Carter, the 39th President of the United States; Carter is the only President who had qualified in submarines, having served as a Communications Officer, Sonar Officer, Electronics Officer, Weapons Officer, and Supply Officer while on board USS Pomfret (SS-391). Jimmy Carter is one of the few ships of the United States Navy (and only the third submarine) to have been named for a person who was alive at the time of the ship's naming, and the first submarine to be named for a living former president.
On 19 November 2004 Jimmy Carter completed alpha sea trials, her first voyage in the open seas. On 22 December, Electric Boat delivered Jimmy Carter to the US Navy, and she was commissioned 19 February 2005 at NSB New London.
USS Seawolf (SSN-575), a unique submarine, 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) nuclear reactor known as the Submarine Intermediate Reactor (SIR) or Liquid Metal Fast Reactor (LMFR), later designated S2G.
Seawolf's keel was laid down 7 September 1953 by the Electric Boat division of General Dynamics Corporation in Groton, Connecticut. She was launched on 21 July 1955 sponsored by Mrs. W. Sterling Cole, and commissioned on 30 March 1957 with Commander R. B. Laning in command.
Like all of the original nuclear subs, the project manager at Electric Boat was the General Manager of the company, Bill Jones. During the parallel construction of the first nuclear submarines, the Navy, the Atomic Energy Commission, its independent labs, and the shipyard all worked together to learn together.
For the yard, the Power Plant Project manager was a separate function on these original nuclear subs. Dennis B. Boykin III would lead EB's power plant installation, and return to the project two years later for the reactor conversion. His counterpart at the Office of Naval Reactors, Gardner Brown, did the same.
Lieutenant James Earl "Jimmy" Carter, the only US President to qualify in submarines, was to be her Engineering Officer, but had resigned his commission upon the death of his father in 1953.

This, in turn, led to the design of the smaller Virginia class. The Seawolf class cost about $3 billion ($3.5 billion for USS Jimmy Carter) making it the most expensive SSN submarine and second most expensive submarine ever after the French SSBN Triomphant class.
