A Landing Helicopter Dock (LHD) is a type of amphibious assault ship designed to support military operations. It can carry helicopters, landing craft, and troops, allowing for versatile deployment in various environments. LHDs are equipped with a flight deck for helicopter operations and a well deck for launching and recovering smaller vessels. These ships play a crucial role in naval warfare and humanitarian missions. They can transport and deploy forces quickly, making them essential for rapid response scenarios. LHDs are often used by navies around the world, including the United States Navy and the Royal Australian Navy.
