This machine breaks all the rules, it can penetrate some of the toughest
terrains on earth, over land, over water, from the polar ice, to the rapids
of the Amazon. This is the ultimate frictionless floating machine, the
A hovercraft, also known as an air-cushion vehicle or ACV, is a craft
capable of travelling over land, water, mud or ice and other surfaces.
Hovercraft are hybrid vessels operated by a pilot as an aircraft rather
than a captain as a marine vessel.
Hovercraft use blowers to produce a large volume of air below the hull that
is slightly above atmospheric pressure. The pressure difference between
the higher pressure air below the hull and lower pressure ambient air above
it produces lift, which causes the hull to float above the running surface.
For stability reasons, the air is typically blown through slots or holes
around the outside of a disk or oval shaped platform, giving most
hovercraft a characteristic rounded-rectangle shape. Typically this
cushion is contained within a flexible "skirt", which allows the vehicle to
travel over small obstructions without damage.
The first practical design for hovercraft derived from a British invention
in the 1950s to 1960s. They are now used throughout the world as
specialised transports in disaster relief, coastguard, military and survey
applications as well as for sport or passenger service. Very large
versions have been used to transport hundreds of people and vehicles across
the English Channel whilst others have military applications used to
transport tanks, soldiers and large equipment in hostile environments and

from the ships of the Kearsarge Amphibious Ready Group at Onslow Beach,
Camp Lejeune, N.C., Feb. 16, 2013. The 26th MEU is conducting its Composite
Training Unit Exercise, the final phase of a six-month pre-deployment
training program. The 26th MEU operates continuously across the globe,
providing the President and unified combatant commanders with a
forward-deployed, sea-based quick reaction force. The MEU is a Marine
Air-Ground Task Force capable of conducting amphibious operations, crisis
response and limited contingency operations. (U.S. Marine Corps motion
