context_page_description: Landing craft are small and medium seagoing watercraft, such as boats and barges, used to convey a landing force 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. This made them difficult to control and very uncomfortable in rough seas. The control point was normally at the extreme rear of the vessel, as were the engines. In all cases, they were known by an abbreviation derived from the official name rather than by the full title.
context_section_description: In the run-up to WWII, many specialized landing craft, both for infantry and vehicles, were developed. In November 1938, the British Inter-Service Training and Development Centre proposed a new type of landing craft. Its specifications were to weigh less than ten long tons, to be able to carry the thirty-one men of a British Army platoon and five assault engineers or signallers, and to be so shallow drafted as to be able to land them, wet only up to their knees, in eighteen inches of water. All of these specifications made the Landing Craft Assault; a separate set of requirements were laid down for a vehicle and supplies carrier, although previously the two roles had been combined in the Motor Landing Craft.
  J. S. White of Cowes built a prototype to the Fleming design. Eight weeks later the craft was doing trials on the River Clyde. All landing craft designs must find a compromise between two divergent priorities; the qualities that make a good sea boat are opposite to those that make a craft suitable for beaching. The craft had a hull built of double-diagonal mahogany planking. The sides were plated with "10lb. DIHT" armour, a heat treated steel based on D1 steel, in this case Hadfield’s Resista ¼”.
  The Landing Craft Assault remained the most common British and Commonwealth landing craft of World War II, and the humblest vessel admitted to the books of the Royal Navy on D-Day. Prior to July 1942, these craft were referred to as "Assault Landing Craft" (ALC), but "Landing Craft; Assault" (LCA) was used thereafter to conform with the joint US-UK nomenclature system.
  The Landing Craft Infantry was a stepped up amphibious assault ship, developed in response to a British request for a vessel capable of carrying and landing substantially more troops than the smaller Landing Craft Assault (LCA). The result was a small steel ship that could land 200 troops, traveling from rear bases on its own bottom at a speed of up to 15 knots (28 km/h; 17 mph). The original British design was envisioned as being a "one time use" vessel which would simply ferry the troops across the English Channel, and were considered an expendable vessel. As such, no troop sleeping accommodations were placed in the original design. This was changed shortly after initial use of these ships, when it was discovered that many missions would require overnight accommodations.
  The first LCI(L)s entered service in 1943 chiefly with the Royal Navy (RN) and United States Navy. Some 923 LCI were built in ten American shipyards and 211 provided under lend-lease to the Royal Navy.
