USS John F. Kennedy (CV-67) (formerly CVA-67) is the only ship of her class, a subclass of the Kitty Hawk-class aircraft carrier, and the last conventionally powered carrier built for the United States Navy. The ship is named after the 35th President of the United States, John F. Kennedy, and is nicknamed "Big John." Kennedy was originally designated a CVA (fixed wing attack carrier); however, the designation was changed to CV to denote that the ship was capable of anti-submarine warfare, making her an all-purpose carrier.
