This is a list of aircraft carriers which are currently in service, reserve, under construction, or being rebuilt. An aircraft carrier is a warship with a full-length flight deck, hangar and facilities for arming, deploying, and recovering aircraft. The list only refers to the status of the ship, not availability or condition of an air wing. Ships classed as amphibious assault ships and helicopter carriers, whose primary purpose is to carry, arm, deploy, and recover aircraft, are included.
