The navy uses various classes of landing craft designed for different operational needs. Here's an overview of some key classes:

1. Landing Craft Air Cushion (LCAC)

The LCAC is a high-speed, amphibious hovercraft used by the U.S. Navy and other military forces. It can transport heavy payloads, including troops, vehicles, and equipment, directly from ship to shore.

2. Landing Craft Utility (LCU)

LCUs are used to transport equipment, vehicles, and troops from amphibious assault ships to the shore. They have a large cargo capacity and can operate independently.

3. Landing Craft Mechanized (LCM)

The LCM class is smaller than the LCU and is used to transport smaller payloads. The LCMs are known for beach landings and ferrying operations.

4. Landing Ship Tank (LST)

LSTs are designed to carry significant amounts of vehicles, cargo, and landing troops directly onto shore without requiring docks or piers.

5. Landing Platform Dock (LPD)

While technically more of a ship than a typical landing craft, the LPD can deploy LCACs, LCUs, and other amphibious vehicles and troops. It's part of a broader logistics and assault operation.

6. Amphibious Assault Vehicle (AAV)

While not a traditional landing craft, the AAV is often launched from larger ships. It is designed to carry troops from water to land, providing mobility and protection.

Each class has its unique features and is chosen based on mission requirements, payload demands, and operational theaters. For a more exhaustive list and detailed specifications, you might want to consult official navy resources or detailed naval military publications.
