A hovercraft, or air-cushion vehicle is a craft, designed to travel over any smooth surface supported by a cushion of slow moving, high-pressure air, ejected downwards against the surface below, and contained within a "skirt." Hovercraft are used throughout the world as a method of specialized transport where ever there is the need to travel over multiple types of surfaces. Because they are supported by a cushion of air, hovercraft are unique among all forms of transportation in their ability to travel equally well over land, ice, and water. Small hovercraft are often used for sport or passenger service, while giant hovercraft have been built for civilian and military applications to transport cars, tanks, and large equipment into difficult or hostile environments and terrain.
