The Wasp class amphibious assault ships of the United States Navy are designed to land forces on hostile shores, and they are the largest vessels of the type in service anywhere in the world. To the untrained eye they look identical to an aircraft carrier. However, despite the fact that they normally carry a small number of AV-8B Harrier II aircraft, and have a secondary role supporting this type in larger numbers, their primary role is not operating fixed wing aircraft. They have a large airwing of helicopters which are dedicated to ferrying troops and equipment ashore from the ships. They also possess a well deck for launching smaller landing craft such as the hovercraft LCAC. The Wasp class vessels are derived from the earlier Tarawa class.
