Landing Ship Docks (LSDs) are specialized naval vessels designed to transport and launch amphibious craft and troops directly onto shore. They have a well deck that can be flooded to allow landing craft, such as LCACs (Landing Craft Air Cushion), to enter and exit the ship. This capability makes LSDs essential for amphibious operations, enabling military forces to conduct beach landings. These ships typically carry a variety of equipment, including vehicles, supplies, and personnel. LSDs are equipped with a flight deck for helicopters, enhancing their versatility in supporting operations. They play a crucial role in modern naval warfare and humanitarian missions.
