An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and hangar facilities for supporting, arming, deploying and recovering shipborne aircraft. Typically it is the capital ship of a fleet, as it allows a naval force to project seaborne air power far from homeland without depending on local airfields for staging aircraft operations. Since their inception in the early 20th century, aircraft carriers have evolved from wooden vessels used to deploy individual tethered reconnaissance balloons, to nuclear-powered supercarriers that carry dozens of fighters, strike aircraft, military helicopters, AEW&Cs and other types of aircraft such as UCAVs. While heavier fixed-wing aircraft such as airlifters, gunships and bombers have been launched from aircraft carriers, these aircraft have not landed on a carrier due to flight deck limitations.
The Wasp-class is a class of landing helicopter dock (LHD) amphibious assault ships operated by the United States Navy. Based on the Tarawa class, with modifications to operate more advanced aircraft and landing craft, the Wasp-class is capable of transporting almost the full strength of a United States Marine Corps Marine Expeditionary Unit (MEU), and landing them in hostile territory via landing craft or helicopters as well as providing air support via AV-8B Harrier II attack aircraft or F-35B Lightning II stealth strike-fighters. All Wasp-class ships were built by Ingalls Shipbuilding, at Pascagoula, Mississippi, with the lead ship, USS Wasp, commissioned on 29 July 1989. Eight Wasp-class ships were built, and as of April 2021, seven are in active service, as USS Bonhomme Richard was seriously damaged by fire on 12 July 2020, and subsequently decommissioned in April 2021.
A landing helicopter dock (LHD) is a multipurpose amphibious assault ship that is capable of operating as a helicopter carrier and also has a well deck for supporting landing crafts. LHD vessels are built with a full flight deck similar in appearance to a light aircraft carrier to operate VTOL rotorcrafts such as utility and attack helicopters, and can also support tiltrotor aircraft and VSTOL fixed-wing aircraft. Some future designs might even support CATOBAR operations for light aircraft and UCAVs via aircraft catapults and arresting gears.
Landing helicopter assault (LHA) is the United States Navy's hull classification symbol for the general-purpose helicopter-carrying amphibious assault ships of the Tarawa and America classes.
An amphibious ready group (ARG) of the United States Navy consists of a naval element—a group of warships known as an Amphibious Task Force (ATF)—and a landing force (LF) of U.S. Marines, in total about 5,000 people. Together, these elements and supporting units are trained, organized, and equipped to perform amphibious operations.
Juan Carlos I is a multi-purpose aircraft carrier-landing helicopter dock (LHD) in the Spanish Navy. Similar in role to many aircraft carriers, the amphibious landing ship has a ski jump for STOVL operations, and is equipped with the McDonnell Douglas AV-8B Harrier II attack aircraft. The vessel is named in honour of Juan Carlos I, the former king of Spain.
A joint support ship (JSS) is a multi-role naval vessel capable of launching and supporting joint amphibious and airlift operations. It can also provide command and control, sealift and seabasing, underway replenishment, disaster relief and logistics capabilities for combined land and sea operations.
The Canberra class is a ship class of two landing helicopter dock (LHD) ships built for the Royal Australian Navy (RAN). Planning to upgrade the navy's amphibious fleet began in 2000, based on Australian experiences leading the International Force for East Timor peacekeeping operation. With a new climate for growing Australian Navy spending, a desire existed for forward defence capability for landing and supporting troops on Asian territory, that had never existed in Australian history, even with the old Majestic-class light fleet carriers, HMAS Melbourne and HMAS Sydney in the 1970s. In 2004, French company Direction des Constructions Navales (DCN) and Spanish company Navantia were invited to tender proposals, with DCN offering the Mistral-class amphibious assault ship and Navantia proposing the "Buque de Proyección Estratégica" design. The Spanish design was selected in 2007, with Navantia responsible for construction of the ships from the keel to the flight deck, and BAE Systems Australia handling the fabrication of the combat and communications systems. Finally, Siemens (Germany) supplied and fitted the azimuth thrusters.
A helicopter carrier is a type of aircraft carrier whose primary purpose is to operate helicopters. It has a large flight deck that occupies a substantial part of the deck, which can extend the full length of the ship like HMS Ocean of the Royal Navy (RN), or extend only partway, usually aft, as in the Soviet Navy's Moskva class or in the Chinese Navy's Type 0891A. It often also has a hangar deck for the storage and maintenance of rotorwing aircraft.
The America class is a ship class of landing helicopter assault (LHA) type amphibious assault ships for the United States Navy (USN). The class is designed to put ashore a Marine Expeditionary Unit using helicopters and MV-22B Osprey V/STOL transport aircraft, supported by AV-8B Harrier II or F-35 Lightning II V/STOL aircraft and various attack helicopters. The first of these warships was commissioned by the U.S. Navy in 2014 to replace USS Peleliu of the Tarawa class; as many as eleven will be built. The design of the America class is based on that of USS Makin Island, the last ship of the Wasp class, but the "Flight 0" ships of the America class will not have well decks, and have smaller on-board hospitals to provide more space for aviation uses.
The Type 071 is a class of Chinese amphibious transport dock ships in service with the People's Liberation Army Navy (PLAN). The Type 071 provides the PLAN with capabilities and flexibility not found in its previous landing ships.
An amphibious assault ship is a type of warship employed to land and support ground forces on enemy territory during an armed conflict. The design evolved from aircraft carriers converted for use as helicopter carriers. Modern designs support amphibious landing craft, with most designs including a well deck. Like the aircraft carriers they were developed from, some amphibious assault ships also support V/STOL fixed-wing aircraft and have a secondary role as aircraft carriers.
The Type 075 landing helicopter dock is a class of Chinese amphibious assault ships built by Hudong–Zhonghua Shipbuilding for the People's Liberation Army Navy (PLAN). It has a full-length flight deck for helicopter operations and features a floodable well deck from which to disembark hovercraft and armored amphibious assault vehicles.
Multi-Role Support Ship (MRSS) is a class of amphibious ship planned for the Royal Malaysian Navy (RMN).
Changsha (173) is a Type 052D destroyer of the People's Liberation Army Navy. She was commissioned on 12 August 2015.
The Type 076 landing helicopter dock is a class of drone-carrying amphibious assault ship for the Chinese People's Liberation Army Navy (PLAN). Compared to the Type 075, the Type 076 is significantly larger in both displacement and flight deck dimensions; it also has a CATOBAR system of electromagnetic catapult and arresting gears for operating light fixed-wing aircraft, likely unmanned combat aerial vehicles (UCAV).
Changbai Shan (989) is a Type 071 amphibious transport dock of the People's Liberation Army Navy.
Yimeng Shan (988) is a Type 071 amphibious transport dock of the People's Liberation Army Navy.
