LST-1級戦車揚陸艦
Dock landing ships, also known as landing ship, dock or LSD, are amphibious warfare ships with well docks to transport and launch landing craft and amphibious vehicles. Some ships with well decks, such as the Soviet Ivan Rogov class, also have bow doors to enable them to deliver vehicles directly onto a beach (like a Landing Ship, Tank). Modern dock landing ships also operate helicopters.
