USS John F. Kennedy, the only ship of her class, was an aircraft carrier, formerly of the United States Navy. Considered a supercarrier, she was a variant of the Kitty Hawk class, and the last conventionally-powered carrier built for the Navy, as all carriers since have had nuclear propulsion. Commissioned in 1968, the ship was named after John F. Kennedy, the 35th president of the United States. John F. Kennedy was originally designated a CVA, for fixed-wing attack carrier, however the designation was changed to CV, for fleet carrier.
