What was the main purpose of the LCAC in amphibious operations?

The main purpose of the Landing Craft Air Cushion (LCAC) in amphibious operations is to conduct over-the-beach landings. The LCAC is a high-speed hovercraft designed to transport troops and equipment from ships directly onto shore, even in challenging conditions where traditional landing craft might struggle. This capability allows for rapid and flexible deployment of forces, enabling them to bypass enemy defenses that might be positioned along traditional landing zones.

The use of the LCAC significantly enhances the ability of armed forces to project power from the sea to the land, especially in environments where deep-water ports are unavailable or where strategic surprise is desired. By being able to operate in shallow waters and directly access the beach, the LCAC plays a crucial role in modern amphibious warfare, allowing for the swift and efficient movement of personnel, vehicles, and supplies right to the point of need on land.
