An '''aircraft carrier''' is a [[Engineering:Warship|warship]] that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for [[Engineering:Carrier-based aircraft|carrying, arming, deploying, and recovering aircraft]].<ref>{{Citation|title=Dictionary|publisher=Reference|contribution-url=http://dictionary.reference.com/browse/aircraft%20carrier|contribution=Aircraft carrier|access-date=3 October 2013|archive-date=19 February 2014|archive-url=https://web.archive.org/web/20140219023059/http://dictionary.reference.com/browse/aircraft%20carrier|url-status=live}}</ref> Typically, it is the [[Engineering:Capital ship|capital ship]] of a fleet, as it allows a naval force to [[Social:Power projection|project]] air power worldwide without depending on [[Engineering:Staging area|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 [[Engineering:Nuclear marine propulsion|nuclear-powered]] warships that carry numerous fighters, strike aircraft, [[Engineering:Military helicopter|helicopters]], and other types of aircraft. While heavier aircraft such as fixed-wing gunships and bombers have been launched from aircraft carriers, these aircraft have not landed on a carrier. 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 [[Engineering:Battleship|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 increases the time of availability on the combat zone.

[[File:Aircraft carrier comparison.jpg|thumb|right|upright=1.25|Comparison of aircraft carriers|alt= An aircraft carrier comparison]]
As of {{#time:F Y}}, there are 47 active aircraft carriers in the world operated by fourteen navies. The United States Navy has 11 large nuclear-powered fleet carriers—carrying around 80 fighters each—the largest carriers in the world; the total combined deck space is over twice that of all other nations combined.<ref>{{cite web |url=https://www.flightglobal.com/news/articles/us-carrier-gap-could-see-naval-air-power-dip-in-gulf-414440/ |title=US "carrier gap" could see naval air power dip in Gulf region |first=James |last=Drew |work=flightglobal.com |date=8 July 2015 |access-date=15 November 2015 |archive-url=https://web.archive.org/web/20151117014726/https://www.flightglobal.com/news/articles/us-carrier-gap-could-see-naval-air-power-dip-in-gulf-414440/ |archive-date=17 November 2015 |url-status=live}}</ref> As well as the aircraft carrier fleet, the US Navy has nine amphibious assault ships used primarily for helicopters, although these also each carry up to 20 vertical or short take-off and landing (V/STOL) fighter jets and are similar in size to medium-sized fleet carriers. India, the United Kingdom and China each operate two aircraft carriers. France and Russia each operate a single aircraft carrier with a capacity of 30 to 60 fighters. Italy operates two light V/STOL carriers and Spain operates one V/STOL aircraft-carrying assault ship. Helicopter carriers are operated by Japan (4, two of which are being converted to operate V/STOL fighters), France (3), Australia (2), Egypt (2), South Korea (2), China (3), Thailand (1) and Brazil (1). Future aircraft carriers are under construction or in planning by China, France, India, Russia, South Korea, Turkey, and the US.

==Types of carriers==
[[File:US Navy 060427-N-5961C-009 USS Ronald Reagan (CVN 76),FS Charles De Gaulle (R-92),FS Cassard (D-614), guided missile cruiser USS Vicksburg (CG 69), USS McCampbell (DDG 85) conduct joint operations in the Persian Gulf.jpg|thumb|French aircraft carrier {{Ship|French aircraft carrier|Charles de Gaulle||2}} (rear), and US Navy carrier {{USS|Ronald Reagan|CVN-76|6}} conducting joint operations in the Persian Gulf; both with the CATOBAR configuration.]]

===General features===
* Speed is a crucial attribute for aircraft carriers, as they need to be able to be deployed quickly anywhere in the world and have to be fast enough to evade detection and targeting from enemy forces. A high speed also increases the "wind over the deck", boosting the lift available for fixed-wing aircraft to carry fuel and ammunition. In order to evade nuclear submarines, the carriers should have a speed of more than 30 knots.
* Aircraft carriers are among the largest types of warships due to their need for ample deck space.
* An aircraft carrier must be able to perform increasingly diverse mission sets. Diplomacy, power projection, quick crisis response force, land attack from the sea, sea base for helicopter and amphibious assault forces, anti-surface warfare (ASUW), Defensive Counter Air (DCA), and [[Social:Humanitarian aid|humanitarian aid]] disaster relief (HADR) are some of the missions the aircraft carrier is expected to accomplish. Traditionally an aircraft carrier is supposed to be one ship that can perform at least power projection and sea control missions.<ref>{{cite web|url= https://www.japcc.org/will-the-aircraft-carrier-survive/|title= Will the Aircraft Carrier Survive?|date= 13 December 2018|access-date= 11 September 2019|archive-date= 12 November 2019|archive-url= https://web.archive.org/web/20191112020122/https://www.japcc.org/will-the-aircraft-carrier-survive/|url-status= live}}</ref>
* An aircraft carrier must be able to efficiently operate an air combat group. This means it should{{cn|date=July 2022}} handle fixed-wing jets as well as helicopters. This includes ships designed to support operations of short-takeoff/vertical-landing (STOVL) jets.

===Basic types===
* [[Engineering:Aircraft cruiser|Aircraft cruiser]]
* Amphibious assault ship and sub-types
* Anti-submarine warfare carrier
* [[Engineering:Balloon carrier|Balloon carrier]] and balloon tenders
* [[Engineering:Escort carrier|Escort carrier]]
* Fleet carrier
* [[Engineering:Flight deck cruiser|Flight deck cruiser]]
* Helicopter carrier
* Light aircraft carrier
* [[Engineering:Sea Control Ship|Sea Control Ship]]
* Seaplane tender and seaplane carriers
* Utility carrier: This type was mainly used in the US Navy, in the decade after World War 2 to ferry aircraft.<ref> [https://www.history.navy.mil/content/history/nhhc/our-collections/photography/us-navy-ships/alphabetical-listing/g/uss-guadalcanal--avg-60-acv-60-cve-60-cvu-60-0.html USS Guadalcanal (AVG-60/ACV-60/CVE-60/CVU-60)], official page at official website https://www.history.navy.mil/ </ref> 

Some of the types listed here are not strictly defined as aircraft carriers by some sources.{{cn|date=July 2022}}

===By role===
[[File:USS Abraham Lincoln (CVN-72) underway in the Atlantic Ocean on 30 January 2019 (190130-N-PW716-1312).JPG|thumb|{{USS|Abraham Lincoln|CVN-72}} a United States Navy fleet carrier, also often referred to as a supercarrier, seen here underway in 2019 crossing the Atlantic.]]

A fleet carrier is intended to operate with the main fleet and usually provides an offensive capability. These are the largest carriers capable of fast speeds. By comparison, [[Engineering:Escort carrier|escort carrier]]s were developed to provide defense for convoys of ships. They were smaller and slower with lower numbers of aircraft carried. Most were built from mercantile hulls or, in the case of [[Engineering:Merchant aircraft carrier|merchant aircraft carrier]]s, were bulk cargo ships with a flight deck added on top. Light aircraft carriers were fast enough to operate with the main fleet but of smaller size with reduced aircraft capacity.

The Soviet aircraft carrier ''Admiral Kusnetsov'' was termed a "heavy aircraft-carrying cruiser". This was primarily a legal construct to avoid the limitations of the Montreux Convention preventing 'aircraft carriers' transiting the Turkish Straits between the Soviet Black Sea bases and the [[Place:Mediterranean Sea|Mediterranean Sea]]. These ships, while sized in the range of large fleet carriers, were designed to deploy alone or with escorts. In addition to supporting fighter aircraft and helicopters, they provide both strong defensive weaponry and heavy offensive missiles equivalent to a guided-missile cruiser.

===By configuration===
[[File:HMS Queen Elizabeth in Gibraltar - 2018 (28386226189).jpg|thumb|Aircraft Carriers in the STOVL configuration are in service with Italy, Spain, Thailand and the United Kingdom.]]

Aircraft carriers today are usually divided into the following four categories based on the way that aircraft take off and land:
*Catapult-assisted take-off barrier-arrested recovery (CATOBAR): these carriers generally carry the largest, heaviest, and most heavily armed aircraft, although smaller CATOBAR carriers may have other limitations (weight capacity of aircraft elevator, etc.). All CATOBAR carriers in service today are nuclear powered. Twelve are in service: ten ''Nimitz'' and one {{sclass|Gerald R. Ford|aircraft carrier|0}} fleet carriers in the United States; and the Charles de Gaulle in France.
* Short take-off barrier-arrested recovery (STOBAR): these carriers are generally limited to carrying lighter fixed-wing aircraft with more limited payloads. STOBAR carrier air wings, such as the [[Engineering:Sukhoi Su-33|Sukhoi Su-33]] and future [[Engineering:Mikoyan MiG-29K|Mikoyan MiG-29K]] wings of {{Ship|Russian aircraft carrier|Admiral Kuznetsov||2}} are often geared primarily towards air superiority and fleet defense roles rather than strike/power projection tasks,{{citation needed|date=November 2013}} which require heavier payloads (bombs and air-to-ground missiles). Five are in service: two in China; two in India and one in Russia.
* [[Engineering:STOVL|Short take-off vertical-landing]] (STOVL): limited to carrying STOVL aircraft. STOVL aircraft, such as the [[Engineering:Harrier jump jet|Harrier]] family and [[Engineering:Yakovlev Yak-38|Yakovlev Yak-38]] generally have limited payloads, lower performance, and high fuel consumption when compared with conventional fixed-wing aircraft; however, a new generation of STOVL aircraft, currently consisting of the [[Engineering:Lockheed Martin F-35 Lightning II|Lockheed Martin F-35B Lightning II]], has much improved performance. Fourteen are in service; nine STOVL amphibious assault ships in the US; two carriers each in Italy and the UK; and one STOVL amphibious assault ship in Spain.
* Helicopter carrier: Helicopter carriers have a similar appearance to other aircraft carriers but operate only helicopters – those that mainly operate helicopters but can also operate fixed-wing aircraft are known as STOVL carriers (see above). Seventeen are in service: four in Japan; three in France; two each in Australia, China, Egypt and South Korea; and one each in Brazil and Thailand. In the past, some conventional carriers were converted and these were called "commando carriers" by the Royal Navy. Some helicopter carriers, but not all, are classified as amphibious assault ships, tasked with landing and supporting ground forces on enemy territory.

===By size===
* Fleet carrier
* Light aircraft carrier
* [[Engineering:Escort carrier|Escort carrier]]

===Supercarrier===

The appellation "supercarrier" is not an official designation with any national navy, but a term used predominantly by the media and typically when reporting on larger and more advanced carrier types. It is also used when comparing carriers of various sizes and capabilities, both current and past. It was first used by ''{{wipe|The New York Times}}'' in 1938,<ref>{{cite news |title= Reich's Cruise Ships Held Potential Plane Carriers |work= The New York Times |date= 1 May 1938 |page= 32 |url= https://www.nytimes.com/1938/05/01/archives/reichs-cruise-ships-held-potential-plane-carriers.html |access-date= 17 May 2015 |archive-url= https://web.archive.org/web/20180224173246/https://www.nytimes.com/1938/05/01/archives/reichs-cruise-ships-held-potential-plane-carriers.html |archive-date= 24 February 2018 |url-status= live}}{{subscription required}}</ref> in an article about the Royal Navy's {{HMS |Ark Royal |91 |6}}, that had a length of {{convert|209|m|ft|sp=us}}, a displacement of 22,000 [[Tonne|ton]] and was designed to carry 72 aircraft.<ref>{{cite news |title=The Ark Royal Launched.

==History==

===Origins===
[[File:Wakamiya.jpg|thumb|right|The {{ship|Japanese seaplane carrier|Wakamiya||2|up=yes}} conducted the world's first naval-launched air raids in 1914.]]

The 1903 advent of the heavier-than-air fixed-wing [[Engineering:Airplane|airplane]] with the [[Biography:Wright brothers|Wright brothers]]' first flight at Kitty Hawk, North Carolina, was closely followed on 14 November 1910, by Eugene Burton Ely's first experimental take-off of a Curtiss Pusher airplane from the deck of a United States Navy ship, the cruiser {{USS|Birmingham|CL-2|6}} anchored off Norfolk Navy Base in Virginia. Two months later, on 18 January 1911, Ely landed his Curtiss Pusher airplane on a platform on the [[Engineering:Armored cruiser|armored cruiser]] {{USS|Pennsylvania|ACR-4|6}} anchored in San Francisco Bay. On 9 May 1912, the first take off of an airplane from a ship while underway was made by Commander Charles Samson flying a Short Improved S.27 [[Engineering:Biplane|biplane]] "S.38" of the Royal Naval Air Service (RNAS) from the deck of the Royal Navy's pre-dreadnought battleship {{HMS|Hibernia|1905|6}}, thus providing the first practical demonstration of the aircraft carrier for naval operations at sea.<ref>{{cite magazine |url=https://www.flightglobal.com/pdfarchive/view/1912/1912%20-%200442.html |title=The Naval Review and the Aviators |issue=177 |volume=IV |page=442 |magazine=Flight |date=18 May 1912 |access-date=15 November 2015 |archive-url=https://web.archive.org/web/20151117015037/https://www.flightglobal.com/pdfarchive/view/1912/1912%20-%200442.html |archive-date=17 November 2015 |url-status=live}}</ref><ref>{{cite news |date=10 May 1912 |title=Flight From the Hibernia |newspaper=The Times |issue= 39895|page=8 (3) |location=London}}</ref> Seaplane tender support ships came next, with the French {{Ship|French seaplane carrier|Foudre||2}} of 1911.

Early in [[Social:World War I|World War I]], the Imperial Japanese Navy ship {{Ship|Japanese seaplane carrier|Wakamiya||2}} conducted the world's first successful ship-launched air raid:{{sfn|Polak|2005|p=92}} on 6 September 1914, a Farman aircraft launched by ''Wakamiya'' attacked the Austro-Hungarian cruiser {{SMS|Kaiserin Elisabeth}} and the Imperial German gunboat ''Jaguar'' in Jiaozhou Bay off Qingdao; neither was hit.<ref>{{cite book |last=Donko |first=Wilhelm M. |title=Österreichs Kriegsmarine in Fernost: Alle Fahrten von Schiffen der k.(u.)k.

The first carrier-launched airstrike was the Tondern raid in July 1918. Seven Sopwith Camels were launched from the battlecruiser {{HMS|Furious|47|6}} which had been completed as a carrier by replacing her planned forward turret with a flight deck and hangar prior to commissioning. The Camels attacked and damaged the German airbase at Tondern, Germany (modern day Tønder, Denmark), and destroyed two zeppelin airships.<ref>Probert, p. 46</ref>

The first landing of an airplane on a moving ship was by Squadron Commander Edwin Harris Dunning, when he landed his [[Engineering:Sopwith Pup|Sopwith Pup]] on HMS ''Furious'' in Scapa Flow, Orkney on 2 August 1917. Landing on the forward flight deck required the pilot to approach round the ship's superstructure, a difficult and dangerous manoeuver and Dunning was later killed when his airplane was thrown overboard while attempting another landing on ''Furious''.<ref>The First World War: A Complete History by Sir Martin Gilbert [https://books.google.com/books?id=Ob2k5aM15cEC&pg=RA2-PA355] {{Webarchive|url=https://web.archive.org/web/20210905151348/https://books.google.com/books?id=Ob2k5aM15cEC&pg=RA2-PA355|date=5 September 2021}}</ref> HMS ''Furious'' was modified again when her rear turret was removed and another flight deck added over a second hangar for landing aircraft over the stern.<ref>Parkes, p. 622.</ref> Her funnel and superstructure remained intact however and [[Physics:Turbulence|turbulence]] from the funnel and superstructure was severe enough that only three landing attempts were successful before further attempts were forbidden.<ref>Parkes, p. 624.</ref> This experience prompted the development of vessels with a flush deck and produced the first large fleet ships.

As a result of the Washington Naval Treaty of 1922, which limited the construction of new heavy surface combat ships, most early aircraft carriers were conversions of ships that were laid down (or had served) as different ship types: cargo ships, cruisers, battlecruisers, or battleships. These conversions gave rise to the US {{sclass|Lexington|aircraft carrier|2}}s (1927), Japanese {{Ship|Japanese aircraft carrier|Akagi||2}} and {{Ship|Japanese aircraft carrier|Kaga||2}}, and British {{sclass|Courageous|aircraft carrier|4}}. Specialist carrier evolution was well underway, with several navies ordering and building warships that were purposefully designed to function as aircraft carriers by the mid-1920s. This resulted in the commissioning of ships such as the Japanese {{Ship|Japanese aircraft carrier|Hōshō||2}} (1922),<ref>{{cite web|url=http://edition.cnn.com/2017/06/13/world/gallery/japanese-inventions-changed-how-we-live/index.html|title=Japanese inventions that changed the world |website= CNN |date=13 June 2017 |access-date=20 February 2018|archive-url=https://web.archive.org/web/20171103173202/http://edition.cnn.com/2017/06/13/world/gallery/japanese-inventions-changed-how-we-live/index.html|archive-date=3 November 2017|url-status=live}}</ref> {{HMS|Hermes|95|6}} (1924, although laid down in 1918 before ''Hōshō''), and {{Ship|French aircraft carrier|Béarn||2}} (1927).

===World War II===

The aircraft carrier dramatically changed naval warfare in World War II, because air power was becoming a significant factor in warfare. The advent of aircraft as focal weapons was driven by the superior range, flexibility, and effectiveness of carrier-launched aircraft. They had greater range and precision than naval guns, making them highly effective. The versatility of the carrier was demonstrated in November 1940, when {{HMS|Illustrious|87|6}} launched a long-range strike on the Italian fleet at their base in Taranto, signalling the beginning of the effective and highly mobile aircraft strikes. This operation in the shallow water harbor incapacitated three of the six anchored battleships at a cost of two torpedo bombers.

World War II in the Pacific Ocean involved clashes between aircraft carrier fleets. The Japanese surprise attack on the American Pacific fleet at Pearl Harbor naval and air bases on Sunday, 7 December 1941, was a clear illustration of the power projection capability afforded by a large force of modern carriers. Concentrating six carriers in a single unit turned naval history about, as no other nation had fielded anything comparable. Further versatility was demonstrated during the "Doolittle Raid", on 18 April 1942, when US Navy carrier {{USS|Hornet|CV-8|6}} sailed to within {{convert|650|nmi|km}} of Japan and launched 16 [[Engineering:North American B-25 Mitchell|B-25 bombers]] from her deck in a retaliatory strike on the mainland, including the capital, Tokyo. However, the vulnerability of carriers compared to traditional battleships when forced into a gun-range encounter was quickly illustrated by the sinking of {{HMS|Glorious}} by German battleships during the Norwegian campaign in 1940.

This new-found importance of naval aviation forced nations to create a number of carriers, in efforts to provide air superiority cover for every major fleet in order to ward off enemy aircraft. This extensive usage led to the development and construction of 'light' carriers. Escort aircraft carriers, such as {{USS|Bogue|CVE-9|6}}, were sometimes purpose-built but most were converted from merchant ships as a stop-gap measure to provide anti-submarine air support for convoys and amphibious invasions. Following this concept, light aircraft carriers built by the US, such as {{USS|Independence|CVL-22|6}}, represented a larger, more "militarized" version of the escort carrier. Although with similar complement to escort carriers, they had the advantage of speed from their converted cruiser hulls. The UK 1942 Design Light Fleet Carrier was designed for building quickly by civilian shipyards and with an expected service life of about 3 years.<ref>{{Cite book |last=Robbins |first=Guy |title=The Aircraft Carrier Story: 1908–1945 |year=2001 |location=London |publisher=Cassel |page=[https://archive.org/details/aircraftcarriers0000robb/page/91 91] |isbn=978-0-30435-308-8 |url=https://archive.org/details/aircraftcarriers0000robb/page/91}}</ref> They served the Royal Navy during the war, and the hull design was chosen for nearly all aircraft carrier equipped navies after the war, until the 1980s. Emergencies also spurred the creation or conversion of highly unconventional aircraft carriers. CAM ships were cargo-carrying merchant ships that could launch (but not retrieve) a single fighter aircraft from a catapult to defend the convoy from long range land-based German aircraft.

Before World War II, international naval treaties of 1922, 1930, and 1936 limited the size of capital ships including carriers. Since World War II, aircraft carrier designs have increased in size to accommodate a steady increase in aircraft size. The large, modern {{sclass|Nimitz|aircraft carrier|4}} of US Navy carriers has a displacement nearly four times that of the World War II–era {{USS|Enterprise|CV-6|6}}, yet its complement of aircraft is roughly the same—a consequence of the steadily increasing size and weight of individual military aircraft over the years. Today's aircraft carriers are so expensive that some nations which operate them risk significant economic and military impact if a carrier is lost.<ref>{{cite web |url=https://www.japcc.org/will-the-aircraft-carrier-survive/ |title=Will the Aircraft Carrier Survive?; Future Air Threats to the Carrier (and How to Defend It) |last=Cochran |first=Daniel |date=2018 |publisher= Joint Air Power Competence Centre (japcc.org) |access-date=7 June 2020 |archive-date=25 July 2020 |archive-url=https://web.archive.org/web/20200725013658/https://www.japcc.org/will-the-aircraft-carrier-survive/ |url-status=live}}</ref>

[[File:USS Forrestal explosion 29 July 1967.jpg|thumb|Fire on board ''Forrestal'' in 1976.]]
Some changes were made after 1945 in carriers:
* The '''angled flight deck''' was invented by Royal Navy Captain (later Rear Admiral) Dennis Cambell, as naval aviation jets higher speeds required carriers be modified to "fit" their needs.<ref>{{cite web |url=http://www.denniscambell.org.uk/4663/4690.html |title=The Angled Deck Story |work=denniscambell.org.uk |year=2012 |access-date=9 November 2015 |archive-url=https://web.archive.org/web/20160304070012/http://www.denniscambell.org.uk/4663/4690.html |archive-date=4 March 2016 |url-status=dead}}</ref><ref>{{cite web |url=http://www.fleetairarmoa.org/fleet-air-arm-oa-history |title=History of Fleet Air Arm Officers Association |work=FAAOA.org |year=2015 |access-date=9 November 2015 |archive-date=25 February 2021 |archive-url=https://web.archive.org/web/20210225040019/https://www.fleetairarmoa.org/fleet-air-arm-oa-history |url-status=live }}</ref><ref>{{cite journal |title=Innovation in Carrier Aviation |first1=Thomas C. |last1=Hone |first2=Norman |last2=Friedman |first3=Mark D. |last3=Mandeles |journal=Newport Paper 37 |publisher=Naval War College Press |year=2011}}; abridged findings published as {{cite journal |title=The Development of the Angled-Deck Aircraft Carrier |journal=Naval War College Review |date=Spring 2011 |volume=64 |number=2 |pages=63–78}}</ref> Additionally, the angled flight deck allows for simultaneous launch and recovery.
* Jet blast deflectors became necessary to protect aircraft and handlers from [[Engineering:Jet blast|jet blast]]. The first US Navy carriers to be fitted with them were the wooden-decked {{sclass|Essex|aircraft carrier|1}}s which were adapted to operate jets in the late 1940s. Later versions had to be water-cooled because of increasing engine power.<ref name="Hobbs2009">Hobbs 2009, Chapter 14</ref>
* Optical landing systems were developed to facilitate the very precise landing angles required by jet aircraft, which have a faster landing speed giving the pilot little time to correct misalignments, or mistakes. The first system was fitted to {{HMS|Illustrious|87|6}} in 1952.<ref name="Hobbs2009"/>
* Aircraft carrier designs have increased in size to accommodate continuous increase in aircraft size. The 1950s saw US Navy's commission of "supercarriers", designed to operate naval jets, which offered better performance at the expense of bigger size and demanded more ordnance to be carried on-board (fuel, spare parts, electronics, etc.).
* The combination of increased carrier size, speed requirements above 30 knots, and a requirement to operate at sea for long periods mean that modern large aircraft carriers often use nuclear reactors to create power for propulsion, electricity, catapulting airplanes from aircraft carriers, and a few more minor uses.<ref>{{cite web|url=https://www.world-nuclear.org/information-library/non-power-nuclear-applications/transport/nuclear-powered-ships.aspx|title=Nuclear-Powered Ships &#124; Nuclear Submarines |website=world-nuclear.org |access-date=11 September 2019|archive-date=25 September 2019|archive-url=https://web.archive.org/web/20190925073832/https://www.world-nuclear.org/information-library/non-power-nuclear-applications/transport/nuclear-powered-ships.aspx|url-status=live}}</ref>

Modern navies that operate such aircraft carriers treat them as [[Engineering:Capital ship|capital ship]]s of fleets, a role previously held by the galleons, ships-of-the-line and [[Engineering:Battleship|battleship]]s. This change took place during World War II in response to air power becoming a significant factor in warfare, driven by the superior range, flexibility and effectiveness of carrier-launched aircraft. Following the war, carrier operations continued to increase in size and importance, and along with, carrier designs also increased in size and ability. Some of these larger carriers, dubbed by the media as "supercarriers", displacing 75,000&nbsp;tons or greater, have become the pinnacle of carrier development. Some are powered by [[Physics:Nuclear reactor|nuclear reactor]]s and form the core of a fleet designed to operate far from home. Amphibious assault ships, such as the {{sclass|Wasp|amphibious assault ship|5}} and {{sclass|Mistral| amphibious assault ship|5}} classes, serve the purpose of carrying and landing Marines, and operate a large contingent of helicopters for that purpose. Also known as "commando carriers"<ref>A number of British conversions of light fleet carriers to helicopter operations were known as commando carriers, though they did not operate landing craft</ref> or "helicopter carriers", many have the capability to operate VSTOL aircraft.

The threatening role of aircraft carriers has a place in modern [[Physics:Asymmetric warfare|asymmetric warfare]], like the gunboat diplomacy of the past.{{cn|date=November 2022}} Carriers also facilitate quick and precise projections of overwhelming military power into such local and regional conflicts.<ref>{{cite web |url=http://archive.navytimes.com/article/20110508/NEWS/105080307/Navies-expanding-use-of-aircraft-carriers |title=Navies expanding use of aircraft carriers |first=Slobodan |last=Lekic |work=Navy Times |date=8 May 2011 |access-date=15 November 2015 |url-status=dead |archive-url=http://archive.wikiwix.com/cache/20151117114109/http://archive.navytimes.com/article/20110508/NEWS/105080307/Navies-expanding-use-of-aircraft-carriers |archive-date=17 November 2015}}</ref>

Lacking the firepower of other warships, carriers by themselves are considered vulnerable to attack by other ships, aircraft, submarines, or missiles. Therefore, an aircraft carrier is generally accompanied by a number of other ships to provide protection for the relatively unwieldy carrier, to carry supplies, re-supply (Many carriers are self-sufficient and will supply their escorts) and perform other support services, and to provide additional offensive capabilities. The resulting group of ships is often termed a carrier strike group, battle group, carrier group, or [[Engineering:Carrier battle group|carrier battle group]].

There is a view among some military pundits {{who|date=December 2020}} that modern anti-ship weapons systems, such as torpedoes and missiles, or even ballistic missiles with nuclear warheads have made aircraft carriers and carrier groups too vulnerable for modern combat.<ref>{{cite magazine |url=http://www.usni.org/magazines/proceedings/2011-05/twilight-uperfluous-carrier |first1=Henry J. |last1=Hendrix |first2=J.

==Description==
===Structure===
Carriers are large and long ships, although there is a high degree of variation depending on their intended role and aircraft complement. The size of the carrier has varied over history and among navies, to cater to the various roles that global climates have demanded from naval aviation.

Regardless of size, the ship itself must house their complement of aircraft, with space for launching, storing, and maintaining them. Space is also required for the large crew, supplies (food, munitions, fuel, engineering parts), and propulsion. US aircraft carriers are notable for having [[Physics:Nuclear reactor|nuclear reactor]]s powering their systems and propulsion.

[[File:DeHavilland Vampire HMS Ocean Dec1945 NAN1 47.jpg|thumb|The first carrier landing and take-off of a jet aircraft: Eric "Winkle" Brown landing on {{HMS|Ocean|R68|6}} in 1945.]]
The top of the carrier is the flight deck, where aircraft are launched and recovered. On the starboard side of this is the island, where the funnel, air-traffic control and the [[Engineering:Bridge (nautical)|bridge]] are located.

The constraints of constructing a flight deck affect the role of a given carrier strongly, as they influence the weight, type, and configuration of the aircraft that may be launched. For example, assisted launch mechanisms are used primarily for heavy aircraft, especially those loaded with air-to-ground weapons. CATOBAR is most commonly used on US Navy fleet carriers as it allows the deployment of heavy jets with full load-outs, especially on ground-attack missions. STOVL is used by other navies because it is cheaper to operate and still provides good deployment capability for fighter aircraft.

Due to the busy nature of the flight deck, only 20 or so aircraft may be on it at any one time. A hangar storage several decks below the flight deck is where most aircraft are kept, and aircraft are taken from the lower storage decks to the flight deck through the use of an elevator. The hangar is usually quite large and can take up several decks of vertical space.<ref>{{cite web|title= How Aircraft Carriers Work|website= How Stuff Works|first= Tom|last= Harris |date= 29 August 2002|url= http://science.howstuffworks.com/aircraft-carrier6.htm |url-status= live|archive-url= https://web.archive.org/web/20131006205343/http://science.howstuffworks.com/aircraft-carrier6.htm |archive-date=6 October 2013}}</ref>

Munitions are commonly stored on the lower decks because they are highly explosive. Usually this is below the waterline so that the area can be flooded in case of emergency.

===Flight deck===
[[File:US Navy 081124-N-3659B-305 F-A-18C Hornets launch from the Nimitz-class aircraft carrier USS Ronald Reagan (CVN 76).jpg|thumb|Catapult launches aboard {{USS|Ronald Reagan}}]]

As "runways at sea", aircraft carriers have a flat-top flight deck, which [[Engineering:Takeoff|launches]] and [[Engineering:Landing|recovers]] aircraft. Aircraft launch forward, into the wind, and are recovered from astern. The flight deck is where the most notable differences between a carrier and a land runway are found. Creating such a surface at sea poses constraints on the carrier. For example, the size of the vessel is a fundamental limitation on runway length. This affects take-off procedure, as a shorter runway length of the deck requires that aircraft [[Physics:Acceleration|accelerate]] more quickly to gain lift. This either requires a thrust boost, a vertical component to its velocity, or a reduced take-off load (to lower mass). The differing types of deck configuration, as above, influence the structure of the flight deck. The form of launch assistance a carrier provides is strongly related to the types of aircraft embarked and the design of the carrier itself.

There are two main philosophies in order to keep the deck short: add thrust to the aircraft, such as using a Catapult Assisted Take-Off (CATO-); and changing the direction of the airplanes' thrust, as in Vertical and/or Short Take-Off (V/STO-). Each method has advantages and disadvantages of its own:
* Catapult assisted take-off but arrested recovery (CATOBAR): A steam- or electric-powered catapult is connected to the aircraft, and is used to accelerate conventional aircraft to a safe flying speed. By the end of the catapult stroke, the aircraft is airborne and further propulsion is provided by its own engines. This is the most expensive method as it requires complex machinery to be installed under the flight deck, but allows for even heavily loaded aircraft to take off.
* Short take-off but arrested recovery (STOBAR) depends on increasing the net lift on the aircraft. Aircraft do not require catapult assistance for take off; instead on nearly all ships of this type an upwards vector is provided by a ski-jump at the forward end of the flight deck, often combined with thrust vectoring by the aircraft. Alternatively, by reducing the fuel and weapon load, an aircraft is able to reach faster speeds and generate more upwards lift and launch without a ski-jump or catapult.
* [[Engineering:STOVL|Short take-off vertical-landing]] (STOVL): On aircraft carriers, non-catapult-assisted, fixed-wing short takeoffs are accomplished with the use of [[Engineering:Thrust vectoring|thrust vectoring]], which may also be used in conjunction with a runway "ski-jump". Use of STOVL tends to allow aircraft to carry a larger payload as compared to during VTOL use, while still only requiring a short runway. The most famous examples are the [[Engineering:Hawker Siddeley Harrier|Hawker Siddeley Harrier]] and the BAe Sea Harrier. Although technically VTOL aircraft, they are operationally STOVL aircraft due to the extra weight carried at take-off for fuel and armaments. The same is true of the [[Engineering:Lockheed Martin F-35 Lightning II|Lockheed F-35B Lightning II]], which demonstrated VTOL capability in test flights but is operationally STOVL or in the case of UK uses "shipborne rolling vertical landing" 
* [[Engineering:VTOL|Vertical take-off and landing]] (VTOL): Certain aircraft are specifically designed for the purpose of using very high degrees of thrust vectoring (e.g. if the thrust to weight-force ratio is greater than 1, it can take off vertically), but are usually slower than conventionally propelled aircraft due to the additional weight from associated systems.

On the recovery side of the flight deck, the adaptation to the aircraft load-out is mirrored. Non-VTOL or conventional aircraft cannot decelerate on their own, and almost all carriers using them must have arrested-recovery systems (-BAR, e.g. CATOBAR or STOBAR) to recover their aircraft. Aircraft that are landing extend a tailhook that catches on arrestor wires stretched across the deck to bring themselves to a stop in a short distance. Post-World War II Royal Navy research on safer CATOBAR recovery eventually led to universal adoption of a landing area angled off axis to allow aircraft who missed the arresting wires to "bolt" and safely return to flight for another landing attempt rather than crashing into aircraft on the forward deck.{{cn|date=July 2022}}<ref>{{Cite web |title=Why Aircraft Carriers Have an Angled Runway |date=2 November 2017 |url=https://www.popularmechanics.com/military/navy-ships/a28881/aircraft-carriers-angle-runway/}}</ref>

If the aircraft are VTOL-capable or helicopters, they do not need to decelerate and hence there is no such need. The arrested-recovery system has used an angled deck since the 1950s because, in case the aircraft does not catch the arresting wire, the short deck allows easier take off by reducing the number of objects between the aircraft and the end of the runway. It also has the advantage of separating the recovery operation area from the launch area. [[Engineering:Helicopter|Helicopter]]s and aircraft capable of vertical or short take-off and landing (V/STOL) usually recover by coming abreast of the carrier on the port side and then using their hover capability to move over the flight deck and land vertically without the need for arresting gear.

====Staff and deck operations====
[[File:F-18 - A 3-wire landing.ogv|thumb|left|F/A-18 Hornet aircraft landing video]]

Carriers steam at speed, up to {{convert|35|kn|lk=in}} into the wind during flight deck operations to increase wind speed over the deck to a safe minimum. This increase in effective wind speed provides a higher launch airspeed for aircraft at the end of the catapult stroke or ski-jump, as well as making recovery safer by reducing the difference between the relative speeds of the aircraft and ship.

Since the early 1950s on conventional carriers it has been the practice to recover aircraft at an angle to port of the axial line of the ship. The primary function of this angled deck is to allow aircraft that miss the arresting wires, referred to as a bolter, to become airborne again without the risk of hitting aircraft parked forward. The angled deck allows the installation of one or two "waist" catapults in addition to the two bow cats. An angled deck also improves launch and recovery cycle flexibility with the option of simultaneous launching and recovery of aircraft.

Conventional ("tailhook") aircraft rely upon a landing signal officer (LSO, radio call sign 'paddles') to monitor the aircraft's approach, visually gauge glideslope, attitude, and airspeed, and transmit that data to the pilot. Before the angled deck emerged in the 1950s, LSOs used colored paddles to signal corrections to the pilot (hence the nickname). From the late 1950s onward, visual landing aids such as the optical landing system have provided information on proper glide slope, but LSOs still transmit voice calls to approaching pilots by radio.

Key personnel involved in the flight deck include the shooters, the handler, and the air boss. Shooters are naval aviators or naval flight officers and are responsible for launching aircraft. The handler works just inside the island from the flight deck and is responsible for the movement of aircraft before launching and after recovery. The "air boss" (usually a commander) occupies the top bridge (Primary Flight Control, also called ''primary'' or ''the tower'') and has the overall responsibility for controlling launch, recovery and "those aircraft in the air near the ship, and the movement of planes on the flight deck, which itself resembles a well-choreographed ballet".<ref>{{cite web|url= http://www.navy.mil/navydata/ships/carriers/powerhouse/powerhouse.asp |title= The US Navy Aircraft Carriers |publisher=Navy.mil |access-date=30 January 2009 |url-status= live |archive-url= https://web.archive.org/web/20090221142917/http://www.navy.mil/navydata/ships/carriers/powerhouse/powerhouse.asp |archive-date= 21 February 2009}}</ref> The captain of the ship spends most of his time one level below primary on the Navigation Bridge. Below this is the Flag Bridge, designated for the embarked admiral and his staff.

To facilitate working on the flight deck of a US aircraft carrier, the sailors wear colored shirts that designate their responsibilities. There are at least seven different colors worn by flight deck personnel for modern United States Navy carrier air operations. Carrier operations of other nations use similar color schemes.

====Deck structures====
[[File:US Navy 100512-N-8446A-004 An F-A-18F Super Hornet assigned to the Fighting Checkmates of Strike Fighter Squadron (VFA) 211 lands aboard the aircraft carrier USS Enterprise (CVN 65).jpg|thumb|Island control structure of {{USS|Enterprise|CVN-65|6}}]]
[[File:FS CDG bridge3.jpg|alt=|thumb|The command bridge of the aircraft carrier {{ship|French aircraft carrier|Charles de Gaulle||2}}]]

The superstructure of a carrier (such as the bridge, flight control tower) are concentrated in a relatively small area called an ''island'', a feature pioneered on {{HMS|Hermes|95|6}} in 1923. While the island is usually built on the [[Engineering:Starboard|starboard]] side of the flight deck, the Japanese aircraft carriers {{ship|Japanese aircraft carrier|Akagi||2}} and {{ship|Japanese aircraft carrier|Hiryū||2}} had their islands built on the [[Port and starboard|port]] side. Very few carriers have been designed or built without an island. The ''flush deck'' configuration proved to have significant drawbacks, primary of which was management of the exhaust from the power plant. Fumes coming across the deck were a major issue in {{USS|Langley|CV-1|6}}. In addition, lack of an island meant difficulties managing the flight deck, performing air traffic control, a lack of radar housing placements and problems with navigating and controlling the ship itself.{{sfn|Friedman|1983|pp=241–243}}

Another deck structure that can be seen is a ski-jump ramp at the forward end of the flight deck. This was first developed to help launch [[Engineering:STOVL|short take off vertical landing]] (STOVL) aircraft take off at far higher weights than is possible with a vertical or rolling takeoff on flat decks. Originally developed by the Royal Navy, it since has been adopted by many navies for smaller carriers. A ski-jump ramp works by converting some of the forward rolling movement of the aircraft into vertical velocity and is sometimes combined with the aiming of jet thrust partly downwards. This allows heavily loaded and fueled aircraft a few more precious seconds to attain sufficient air velocity and lift to sustain normal flight. Without a ski-jump, launching fully-loaded and fueled aircraft such as the Harrier would not be possible on a smaller flat deck ship before either stalling out or crashing directly into the sea.

Although STOVL aircraft are capable of taking off vertically from a spot on the deck, using the ramp and a running start is far more fuel efficient and permits a heavier launch weight. As catapults are unnecessary, carriers with this arrangement reduce weight, complexity, and space needed for complex steam or electromagnetic launching equipment. Vertical landing aircraft also remove the need for arresting cables and related hardware. Russian, Chinese, and Indian carriers include a ski-jump ramp for launching lightly loaded conventional fighter aircraft but recover using traditional carrier arresting cables and a tailhook on their aircraft.

The disadvantage of the ski-jump is the penalty it exacts on aircraft size, payload, and fuel load (and thus range); heavily laden aircraft cannot launch using a ski-jump because their high loaded weight requires either a longer takeoff roll than is possible on a carrier deck, or assistance from a catapult or JATO rocket. For example, the Russian [[Engineering:Sukhoi Su-33|Sukhoi Su-33]] is only able to launch from the carrier {{ship|Russian aircraft carrier|Admiral Kuznetsov||2}} with a minimal armament and fuel load. Another disadvantage is on mixed flight deck operations where helicopters are also present, such as on a US landing helicopter dock or landing helicopter assault amphibious assault ship. A ski jump is not included as this would eliminate one or more helicopter landing areas; this flat deck limits the loading of Harriers but is somewhat mitigated by the longer rolling start provided by a long flight deck compared to many STOVL carriers.

The US Navy has the largest fleet of carriers in the world, with eleven supercarriers currently in service. China and India each have two STOBAR carriers in service. The UK has two STOVL carriers in service. The navies of France and Russia each operate a single medium-sized carrier.{{efn|Russian carrier has not been operational since 2018; it is expected to be launched again in 2024.}} The US also has nine similarly sized Amphibious Warfare Ships. There are five small light carriers in use capable of operating both fixed-wing aircraft and helicopters; Japan and Italy each operate two, and Spain one.

Additionally there are eighteen small carriers which only operate helicopters serving the navies of Australia (2), Brazil (1), China (2), Egypt (2), France (3), Japan (4), South Korea (2), Thailand (1) and Turkey (1).

Nine amphibious assault ships carrying vehicles, Marine fighters, attack and transport helicopters, and landing craft with STOVL fighters for CAS and CAP:
* {{sclass|America|amphibious assault ship|4}}: a class of 45,000-tonne amphibious assault ships, although the first two ships in this class, (Flight 0) do not have well decks, all subsequent ships (Flight I) will have well decks.

Following the deactivation of {{USS|Enterprise|CVN-65|6}} in December 2012, the US fleet comprised 10 fleet carriers, but that number increased back to 11 with the commissioning of ''Gerald R. Ford'' in July 2017. The House Armed Services Seapower subcommittee on 24 July 2007, recommended seven or eight new carriers (one every four years). However, the debate has deepened over budgeting for the $12–14.5&nbsp;billion (plus $12&nbsp;billion for development and research) for the 100,000-tonne ''Gerald R. Ford''-class carrier (estimated service 2017) compared to the smaller $2&nbsp;billion 45,000-tonne {{sclass|America|amphibious assault ship|1}}s, which are able to deploy squadrons of F-35Bs. The first of this class, {{USS|America|LHA-6|6}}, is now in active service with another, {{USS|Tripoli|LHA-7|6}}, and 9 more are planned.<ref name="AFAmag">{{cite magazine |last= Kreisher |first= Otto |title= Seven New Carriers (Maybe) |magazine= Air Force Magazine |volume= 90 |issue= 10 |pages= 68–71 |date= October 2007 |publisher= Air Force Association |url= http://www.airforce-magazine.com/MagazineArchive/Pages/2007/October%202007/1007carriers.aspx |access-date= 2 October 2007 |issn= 0730-6784 |archive-url= https://web.archive.org/web/20090423170322/http://www.airforce-magazine.com/MagazineArchive/Pages/2007/October%202007/1007carriers.aspx |archive-date= 23 April 2009 |url-status= live}}</ref><ref>{{cite news |url= http://articles.dailypress.com/2014-05-08/business/dp-nws-huntingon-ingalls-earnings-20140508_1_sequestration-level-budget-cuts-return-rcoh-huntington-ingalls-industries |title=Huntington Ingalls, Newport News shipyard upbeat despite budget clouds |newspaper=Daily Press |date=8 May 2014 |access-date=29 May 2014 |archive-url= https://web.archive.org/web/20140531105311/http://articles.dailypress.com/2014-05-08/business/dp-nws-huntingon-ingalls-earnings-20140508_1_sequestration-level-budget-cuts-return-rcoh-huntington-ingalls-industries |archive-date=31 May 2014 |url-status=live}}</ref>
