Landing Ship, Tank (LST), or tank landing ship, is the naval designation for ships first developed during World War II (1939–1945) to support amphibious operations by carrying tanks, vehicles, cargo, and landing troops directly onto a low slope beach with no docks or piers. The shallow draft and bow doors and ramps enabled amphibious assaults on almost any beach.
