how many aircraft carriers does us navy have
List of aircraft carriers of the United States Navy Later in the Cold War era, the first of the classes dubbed "supercarriers" was born, starting with USS Forrestal (CV-59),[10] followed by the Kitty Hawk-class and single ships Enterprise (CVN-65), the first nuclear powered carrier and John F. Kennedy (CV-67), the last conventionally powered carrier. These were then followed by the Nimitz-class and the post-cold war Gerald R. Ford-class nuclear supercarriers, the only classes that are currently in active-duty service.[11] The ten-ship Nimitz-class is complete, while USS Gerald R. Ford (CVN-78), the lead ship of her planned ten-ship class, is the only ship active so far, with construction started on two more ships, John F. Kennedy (CVN-79) and Enterprise (CVN-80).[12][13]
