ship with a long, unobstructed flight deck that permits takeoffs and landings by high-performance airplanes; a carrier is in effect a mobile air base. Planes are stored below deck and brought up and down on elevators. They take off under their own power or may be launched by catapults. Mirror landing systems and arresting cables that catch a hook on the outside of incoming aircraft facilitate safe landings. Decks are angled so that pilots missing the arresting gear will be able to go around again without hitting other aircraft. Carriers, equipped with or capable of carrying missiles, are the heart of modern striking forces, accompanied by a variety of support vessels: destroyers and cruisers for protection and supply ships bearing fuel, ammunition, and food.
