HMS Ocean (1995), is sometimes called an amphibious assault ship but, at 21,500 tons, is designated a Landing Platform Helicopter. Wasp-class amphibious assault ships are 40,000 ton VTOL vessels, compared to the Brazilian (ex-French) 32,000 CATOBAR carrier, São Paulo. Whenever a nation, with power projection capability, faces a crisis, among the first questions asked by its leaders is "Where are the carriers?" Other than those exclusively for amphibious or antisubmarine operations, the worldwide navies with carriers in operation or under construction include:įor amphibious warfare, several nations also have STOVL or VTOL ships that are not called "carriers", although this is often for reasons of domestic, or even interservice, politics. Two 65,000 ton British Queen Elizabeth-class carriers under construction, as well as possible future French construction that would use the British design, will start as STOVL, but are intended to be convertible to CATOBAR. At present, only the United States, France, and Brazil operate CATOBAR carriers. This technique is called Catapult Assisted Take Off But Arrested Recovery ( CATOBAR) the catapult and arresting systems are major components, but certainly not the only ones involved. The largest and most capable carriers have catapults that can, in seconds, accelerate carrier-capable conventional takeoff and landing (CTOL) small and medium aircraft to flying speed they also have a system of arresting wires, which allows a high-performance aircraft to be brought to a stop in seconds. Smaller carriers may only be able to operate short takeoff and vertical landing (SVTOL) aircraft, as well as vertical takeoff and landing (VTOL) helicopters and tilt-rotor aircraft. An aircraft carrier is a warship designed to support and operate aircraft, engage in attacks on targets afloat or ashore, and engage in sustained operations in support of other forces.
