This list includes only warships that are currently in service. It do not includes retired ships or vessels that are currently being built. This list includes multi-purpose warships, that can function as amphibious assault ships.

CurrentlyTop 10 Amphibious Assault Shipsin the world are these:

3. Canberra class (Australia)

   The Australian Canberra class amphibious assault ships are smaller than similar American ships. The HMAS Canberra was commissioned in 2014. The second ship is planned to be commissioned in 2016.

 

   The Canberra class ships can carry 1 125 marines. Surge capacity for a short period of time is 1 600 marines.

These ships were designed by a Spanish company. Design of the Canberra class is similar to that of the Juan Carlos I. Australian ships have the same dimensions, as the Spanish Juan Carlos I, but different internal layout and island superstructure. Even though both the Spanish Juan Carlos I and Australian Canberra class ships are multi-functional, the Juan Carlos I has stronger air wing and the Canberra class ships have stronger amphibious assault capability.

   These warships have two vehicle decks. One of them is for light vehicles. The other is for heavy vehicles and tanks. The Canberra class can transport about 45 main battle tanks, or more lighter vehicles.

   There are four LCM-1E landing craft housed in a well deck. These are used for delivery of troops, vehicles and supplies from ship to shore.

    The hangar accommodates 8 medium-size helicopters. A room can be made for additional 10 helicopters in the light vehicle deck. Typical airgroup is a mix of NH90 transport helicopters and S-70B Seahawk anti-submarine helicopters.

Flight deck has 6 spots for NH90 or S-70B Seahawk size helicopters or alternatively up to 4 larger Chinook size helicopters that can operate simultaneously.

    The Canberra class ships have a sky-jump ramps but need some modifications in order to operate fixed-wing aircraft such as the F-35B. In the near future there are no plans to operate fixed-wing aircraft from these ships.

2. Wasp class (USA)

   The Wasp class is a follow-on from the Tarawa class and its ships share the same basic hull and engineering plant. The lead ship, USS Wasp, was commissioned in 1989. At the time if their introduction the Wasp class vessels were the largest amphibious assault ship in the world. However currently the new America class ships are even larger.

   The Wasp class ships are capable of embarking a 2 000-strong marine expeditionary unit. The troops are landed on the beach using landing craft, or deliver further inland via helicopters. A total of 61 AAV7A1 amphibious assault vehicles can be carried.

These were the first ships specially designed to operate both the AV-8B Harrier II and a complement of LCAC hovercraft. Each Wasp class can accommodate up to three LCACs or twelve LCMs

   The flight deck has nine landing spots for helicopters and up to 42 CH-46 Sea Knights could be operated. The class can also deploy AH-1 SeaCobra attack helicopters or other transports such as the CH-53E Super Stallion, UH-1N Twin Huey or the multi-purpose SH-60B Seahawk. The Wasp class can operate six to eight AV-8B Harrier IIs in the combat role, but can support up to 20.

1. America class (USA)

   Currently the America class amphibious assault ships, are the largest vessels in this class ever built. These ships are larger than most aircraft carriers.

The America class has been specially optimized for the new MV-22 Osprey tilt rotor transport and F-35B VTOL strike fighter. Warships of this class can even serve as small aircraft carrier. These can operate a total of 38 helicopters and VSTOL aircraft, including F-35B JSF, MV-22 Osprey, UH-1Y Huey, CH-53E Sea Stallion, SH-60 Sea Hawk, MH-60 Nighthawk, AH-1Z Viper, AH-1W Super Cobra, and other. Number of aircraft and helicopters will vary depending on specific mission requirements.

america-class

   Design of the America class is based on the last ship of the Wasp class. However the new ships have more deck space and larger hangar facilities to house more aircraft below decks. The lead ship, USS America, was commissioned with the US Navy in 2014. As of 2015 it is the only active ship of this class. Another ship is under construction, while the third is planned. America class warships will eventually replace the ageing Tarawa class.

   The first two ships of the class are optimized for aviation. These have no well decks and do not support amphibious assault by sea. Marines are delivered ashore by helicopters. Such delivery method allows troops to arrive more quickly and much further out. Also the vessels are better protected as they can launch assaults further out from sea. The following America class ships that are currently planned will have a well deck, but will carry fewer aircraft.

   The America class can carry 1 700 marines and associated equipment to support them.
