HovercraftA hovercraft (: hovercraft), also known as an air-cushion vehicle or ACV, is an amphibious craft capable of travelling over land, water, mud, ice, and other surfaces. Hovercraft use blowers to produce a large volume of air below the hull, or air cushion, 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.
Amphibious vehicleAn amphibious vehicle (or simply amphibian), is a vehicle that is a means of transport viable on land as well as on or under water. Amphibious vehicles include amphibious bicycles, ATVs, cars, buses, trucks, railway vehicles, combat vehicles and hovercraft. Classic landing craft are not amphibious vehicles as they do not offer any real land transportation at all, although they are part of amphibious warfare. Ground effect vehicles, such as ekranoplans, will likely crash on any but the flattest of landmasses so are also not considered to be amphibious vehicles.
Task forceA task force (TF) is a unit or formation established to work on a single defined task or activity. Originally introduced by the United States Navy, the term has now caught on for general usage and is a standard part of NATO terminology. Many non-military organizations now create "task forces" or task groups for temporary activities that might have once been performed by ad hoc (designated purpose) committees.
Landing Craft AssaultLanding Craft Assault (LCA) was a landing craft used extensively in World War II. Its primary purpose was to ferry troops from transport ships to attack enemy-held shores. The craft derived from a prototype designed by John I. Thornycroft Ltd. of Woolston, Hampshire, UK. During the war it was manufactured throughout the United Kingdom in places as various as small boatyards and furniture manufacturers.
BeachheadA beachhead is a temporary line created when a military unit reaches a landing beach by sea and begins to defend the area as other reinforcements arrive. Once a large enough unit is assembled, the invading force can begin advancing inland. The term is sometimes used interchangeably (both correctly and incorrectly) with bridgehead and lodgement. Beachheads were important in many military actions; examples include operations such as Operation Neptune during World War II, the Korean War (especially at Inchon), and the Vietnam War.
Dieppe RaidOperation Jubilee or the Dieppe Raid (19 August 1942) was an Allied amphibious attack on the German-occupied port of Dieppe in northern France, during the Second World War. Over 6,050 infantry, predominantly Canadian, supported by a regiment of tanks, were put ashore from a naval force operating under protection of Royal Air Force (RAF) fighters. The port was to be captured and held for a short period, to test the feasibility of a landing and to gather intelligence.
Allied invasion of ItalyThe Allied invasion of Italy was the Allied amphibious landing on mainland Italy that took place from 3 September 1943, during the Italian campaign of World War II. The operation was undertaken by General Sir Harold Alexander's 15th Army Group (comprising General Mark W. Clark's American Fifth Army and General Bernard Montgomery's British Eighth Army) and followed the successful Allied invasion of Sicily.
Naval gunfire supportNaval gunfire support (NGFS), also known as naval surface fire support (NSFS), or shore bombardment, is the use of naval artillery to provide fire support for amphibious assault and other troops operating within their range. NGFS is one of several disciplines encompassed by the term naval fires. Modern naval gunfire support is one of the three main components of amphibious warfare assault operations support, along with aircraft and ship-launched land-attack missiles.
Patrol boatA patrol boat (also referred to as a patrol craft, patrol ship, or patrol vessel) is a relatively small naval vessel generally designed for coastal defence, border security, or law enforcement. There are many designs for patrol boats, and they generally range in size. They may be operated by a nation's navy, coast guard, police, or customs, and may be intended for marine ("blue water"), estuarine ("green water"), or river ("brown water") environments.
Landing craftLanding craft are small and medium seagoing watercraft, such as boats and barges, used to convey a landing force (infantry and vehicles) from the sea to the shore during an amphibious assault. The term excludes landing ships, which are larger. Production of landing craft peaked during World War II, with a significant number of different designs produced in large quantities by the United Kingdom and United States. Because of the need to run up onto a suitable beach, World War II landing craft were flat-bottomed, and many designs had a flat front, often with a lowerable ramp, rather than a normal bow.
