Helicopter carrier 直升机航空母舰
A helicopter carrier is a type of aircraft carrier whose primary purpose is to operate helicopters. Helicopter carriers have been used as anti-submarine warfare 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, the
Chinese Navy's Type 0891A or RFA Argus. A full-length deck maximises deck space for helicopter landing spots. Such a design also allows for a hangar deck.
