An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft. Typically, it is the capital ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations. Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry numerous fighters, strike aircraft, helicopters, and other types of aircraft. While heavier aircraft such as fixed-wing gunships and bombers have been launched from aircraft carriers, it is currently not possible to land them. By its diplomatic and tactical power, its mobility, its autonomy and the variety of its means, the aircraft carrier is often the centerpiece of modern combat fleets. Tactically or even strategically, it replaced the battleship in the role of flagship of a fleet. One of its great advantages is that, by sailing in international waters, it does not interfere with any territorial sovereignty and thus obviates the need for overflight authorizations from third-party countries, reduces the times and transit distances of aircraft and therefore significantly increase the time of availability on the combat zone.
The escort carrier or escort aircraft carrier, also called a "jeep carrier" or "baby flattop" in the United States Navy (USN) or "Woolworth Carrier" by the Royal Navy, was a small and slow type of aircraft carrier used by the Royal Navy, the United States Navy, the Imperial Japanese Navy and Imperial Japanese Army Air Force in World War II. They were typically half the length and a third the displacement of larger fleet carriers, slower, carried fewer planes, and more-lightly armed and armored. Escort carriers were most often built upon a commercial ship hull, so they were cheaper and could be built quickly. This was their principal advantage as they could be completed in greater numbers as a stop-gap when fleet carriers were scarce. However, the lack of protection made escort carriers particularly vulnerable, and several were sunk with great loss of life. The light carrier was a similar concept to the escort carrier in most respects, but was fast enough to operate alongside fleet carriers.
The United States Navy, United States Coast Guard, and United States National Oceanic and Atmospheric Administration (NOAA) use a hull classification symbol to identify their ships by type and by individual ship within a type. The system is analogous to the pennant number system that the Royal Navy and other European and Commonwealth navies use.
Landing platform helicopter (LPH) is a term used by some navies to denote a type of amphibious warfare ship designed primarily to operate as a launch and recovery platform for helicopters and other VTOL aircraft. As such, they are considered a type of helicopter carrier.
A landing helicopter dock (LHD) is a multipurpose amphibious assault ship which is capable of operating helicopters and has a well deck. The United States Navy (USN) and the Royal Australian Navy (RAN) use the term as a hull classification symbol.
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.
The names of commissioned ships of the United States Navy all start with USS, for United States Ship. Non-commissioned, primarily civilian-manned vessels of the U.S. Navy under the Military Sealift Command have names that begin with USNS, standing for United States Naval Ship. A letter-based hull classification symbol is used to designate a vessel's type. The names of ships are selected by the Secretary of the Navy. The names are those of states, cities, towns, important persons, important locations, famous battles, fish, and ideals. Usually, different types of ships have names originated from different types of sources.
Juan Carlos I is a multi-purpose amphibious assault ship-aircraft carrier in the Spanish Navy. Similar in role to many aircraft carriers, the ship has a ski jump for STOVL operations, and is equipped with the AV-8B Harrier II attack aircraft. The vessel is named in honour of Juan Carlos I, the former King of Spain.
A helicopter carrier is a type of aircraft carrier whose primary purpose is to operate helicopters. A helicopter carrier has a large flight deck that occupies a large part of the ship, which can extend the full length of the ship like HMS Ocean of the Royal Navy (RN), or only partway, usually aft, as in the Soviet Navy's Moskva class, the Chinese Navy's Type 0891A or the Royal Fleet Auxiliary's (RFA) RFA Argus. It often also has a hangar deck for the storage of aircraft.
The America class is a ship class of landing helicopter assault (LHA) type amphibious assault ships of 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 they have smaller on-board hospitals in order to give more space for aviation uses.
The aircraft cruiser is a warship that combines the features of the aircraft carrier and a surface warship such as a cruiser or battleship.
USS America (LHA-6), is an amphibious assault ship of the United States Navy and the lead ship of her class. The fourth U.S. warship to be named for the United States of America, she was delivered in spring of 2014, replacing Peleliu of the Tarawa class. Her mission is to act as the flagship of an expeditionary strike group or amphibious ready group, carrying part of a Marine expeditionary unit into battle and putting them ashore with helicopters and V-22 Osprey tilt-rotor aircraft, supported by F-35B Lightning II aircraft and helicopter gunships.
An amphibious assault ship is a type of amphibious warfare ship employed to land and support ground forces on enemy territory by an amphibious assault. The design evolved from aircraft carriers converted for use as helicopter carriers. Modern ships support amphibious landing craft, with most designs including a well deck. Coming full circle, some amphibious assault ships also support V/STOL fixed-wing aircraft, now having a secondary role as aircraft carriers.
An amphibious warfare ship is an amphibious vehicle warship employed to land and support ground forces, such as marines, on enemy territory during an amphibious assault. The largest fleet of these types is operated by the United States Navy.
The United States Navy (USN) is the maritime service branch of the United States Armed Forces and one of the eight uniformed services of the United States. It is the largest and most powerful navy in the world, with the estimated tonnage of its active battle fleet alone exceeding the next 13 navies combined, including 11 U.S. allies or partner nations. It has the highest combined battle fleet tonnage and the world's largest aircraft carrier fleet, with eleven in service, two new carriers under construction, and five other carriers planned. With 336,978 personnel on active duty and 101,583 in the Ready Reserve, the U.S. Navy is the third largest of the U.S. military service branches in terms of personnel. It has 290 deployable combat vessels and more than 3,700 operational aircraft as of June 2019.
A ship's company comprises all officers, non-commissioned officers and enlisted personnel aboard a naval vessel. The size of the ship's company is the number of people on board, excluding civilians and guests.
India's Ministry of Defence had finalised a project for the procurement of four Landing Helicopter Docks in order to upgrade the Indian Navy's disaster response, amphibious warfare and island protection capabilities. The project was worth ₹16,000 crore, and tenders were issued in December 2013 to three domestic shipyards.
TCG Anadolu (L-400) is an amphibious assault ship (LHD) of the Turkish Navy that can be configured as a light aircraft carrier. It is named after the peninsula of Anatolia which forms the majority of the land mass of Turkey. The construction works began on 30 April 2016 at the shipyard of Sedef Shipbuilding Inc. in Istanbul, with the keel being laid 7 February 2018, and is expected to be completed in 2020. The vessel is intended to meet the various needs and requirements of the Turkish Armed Forces, such as sustaining long-endurance, long-distance military combat or humanitarian relief operations; while acting as a command center and flagship for the Turkish Navy.
