USS Jimmy Carter (SSN-23), the third and last Seawolf-class submarine, is the first ship of the United States Navy to be named for the 39th President of the United States, Jimmy Carter, who served in the United States Navy 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; Jimmy Carter is the only U.S. President to qualify in submarines.
