Concept
Landing Craft Tank
Résumé
The landing craft, tank (LCT) (or tank landing craft, TLC) was an amphibious assault craft for landing tanks on beachheads. They were initially developed by the Royal Navy and later by the United States Navy during World War II in a series of versions. Initially known as the "tank landing craft" (TLC) by the British, they later adopted the U.S. nomenclature "landing craft, tank" (LCT). The United States continued to build LCTs post-war, and used them under different designations in the Korean and Vietnam Wars.

In 1926, the first motor landing craft (MLC1) was built by the Royal Navy. It weighed 16 tons, with a draught of , and was capable of about . It was later developed into the landing craft mechanised.
It was at the insistence of the British prime minister Winston Churchill in mid-1940 that the LCT was created. Its speed was on engines delivering about . Designated the LCT Mark 1, 20 were ordered in July 1940 and a further 10 in October 1940.)
The first LCT Mark 1 was launched by Hawthorn Leslie in November 1940. It was designed to land three of the heaviest tanks (40t) then envisaged for the British Army in 2 ft 6ins of water on a 1:35 gradient beach. They were designed on the same principle as a floating dock, with watertight side pontoons on each side joined by a tank deck set below the waterline. The tank deck swept up above the waterline near the bow before falling away again to the ramp. Engines were two Hall Scott Defender petrol engines of 500 hp each. The craft were arranged in four sections so they could be shipped to the Eastern Mediterranean as deck cargo on merchant ships. Thirty of these craft were ordered.
The LCT Mark 2 was longer and wider than the Mark 1, with three Napier Lion petrol engines replacing the Hall-Scotts as these were required for Coastal Forces craft. At , it had three times the range of its predecessor. Seventy-three Mk.2s were built.
Increasing the beam of the Mk2 by allowed a much greater cargo capacity of lighter vehicles, where the Mk1 could only carry three Valentine tanks the Mark 2 could carry 7.
