'

Air cushion craft (ACC) is a type of vehicle that moves across or over the surface of water, mud or ice with the help of an inflatable cushion of air. It is a form of hovercraft, which was the world's first true amphibious vehicle.

ACCs have come a long way since their early days. They are now used for a variety of applications, such as transportation of goods and passengers, search and rescue, recreation, exploration and even military operations. ACCs have many advantages over traditional boats and other forms of watercraft.

An ACC's air cushion is created by a fan that takes in air from the atmosphere and pushes it out through a skirt at the bottom of the craft. This cushion of air creates a barrier between the craft and the ground or water below, allowing the craft to operate with a minimum of friction. This allows ACCs to travel at high speeds with little effort, making them a preferred choice for transporting goods or passengers over long distances.

ACCs also have the ability to move over a variety of surfaces with relative ease. They can even operate on land, which makes them ideal for accessing remote locations or navigating through difficult terrain. This also makes them useful in search and rescue operations, as they can access areas quickly and safely.

ACCs are typically powered by diesel or petrol engines, although electric and hybrid models are becoming more common. They come in a variety of sizes, from large craft capable of carrying hundreds of passengers, to smaller models designed for recreational use.

ACCs are set to become increasingly important vehicles in the years to come, as they are becoming more versatile and reliable. As technology continues to improve, ACCs will become even more reliable, efficient and versatile, making them a key part of the future of transportation.
