Helicopter carrier

Helicopter carrier is a term for an aircraft carrier whose primary purpose is to operate helicopters. The term is sometimes used for both ASW carriers and amphibious assault ships.

Helicopter carriers can either have a full-length aircraft deck like HMS Ocean, or have a large helicopter deck, usually aft, as in the Soviet Navy's Moskva class or RFA Argus. The large aft deck design is becoming less common, as the configuration represents a compromise. A full-length deck maximises deck space for helicopter landing spots. Such a design also allows for a hangar deck.

Pure helicopter carriers are difficult to define in the 21st century. The advent of STOVL aircraft such as the Harrier Jump Jet have complicated the classification; the United States Navy's Wasp class, for instance, carries six to eight Harriers as well as 30 helicopters. Only smaller carriers unable to operate the Harrier and older pre-Harrier-era carriers can be regarded as true helicopter carriers. In many cases, other carriers, able to operate STOVL aircraft, are classified as "light aircraft carriers". Other vessels, such as the Wasp class, are also capable of embarking troops such as Marines and landing them ashore; they are typically classified as amphibious assault ships.

HMS Hermes and two of her sisters were 22,000 ton fleet carriers converted to operate helicopters only as "commando carriers". Hermes was later converted to a STOVL carrier.
