Naval aviation / Aeronaval is the application of military air power by navies , whether from warships that embark aircraft, or land bases. It often involves navalised aircraft , specifically designed for naval use. Seaborne aviation encompasses similar activities not restricted to navies, including marines and coast guards , such as in U.S. naval aviators .

179-779: Naval aviation units are typically projected to a position nearer the target by way of an aircraft carrier . Carrier-based aircraft must be sturdy enough to withstand the demands of carrier operations. They must be able to launch in a short distance and be sturdy and flexible enough to come to a sudden stop on a pitching flight deck; they typically have robust folding mechanisms that allow higher numbers of them to be stored in below-decks hangars and small spaces on flight decks. These aircraft are designed for many purposes, including air-to-air combat , surface attack , submarine attack , search and rescue , matériel transport, weather observation , reconnaissance and wide area command and control duties. Naval helicopters can be used for many of

358-755: A Short Improved S.27 biplane "S.38" of the Royal Naval Air Service (RNAS) from the deck of the Royal Navy's pre-dreadnought battleship HMS  Hibernia , thus providing the first practical demonstration of the aircraft carrier for naval operations at sea. Seaplane tender support ships came next, with the French Foudre of 1911. Early in World War I , the Imperial Japanese Navy ship Wakamiya conducted

537-518: A Short Type 184 seaplane, launched from the seaplane carrier HMS  Ben-my-Chree . The first carrier-launched airstrike was the Tondern raid in July 1918. Seven Sopwith Camels were launched from the battlecruiser HMS  Furious 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

716-499: A flight deck on the fore-deck; in 1917 it was reconstructed with separate flight decks fore and aft of the superstructure; then finally, after the war, it was heavily reconstructed with a three-quarter length main flight deck, and a lower-level take-off only flight deck on the fore-deck. On 2 August 1917, Squadron Commander E.H. Dunning , Royal Navy, landed his Sopwith Pup aircraft on Furious in Scapa Flow , Orkney , becoming

1074-405: A carrier due to flight deck limitations. The aircraft carrier, along with its onboard aircraft and defensive ancillary weapons , is the largest weapon system ever created. By their tactical prowess, mobility, autonomy and the variety of operational means, aircraft carriers are often the centerpiece of modern naval warfare , and have significant diplomatic influence in deterrence , command of

1253-403: A country's seagoing forces with air cover over areas that may not be reachable by land-based aircraft, giving them a considerable advantage over navies composed primarily of surface combatants. Naval aviation also provides countries with the opportunity to deploy military aircraft over land and sea, without the need for air bases on land. Aircraft may be used to conduct naval mine clearance ,

Naval aviation also provides countries with the opportunity to deploy military aircraft over land and sea, without the need for air bases on land. Aircraft may be used to conduct naval mine clearance ,

1611-550: A demonstrative retaliatory strike on the mainland, including the capital, Tokyo. However, the vulnerability of carriers compared to traditional capital ships was 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 to ward off enemy aircraft. This extensive usage led to

1790-412: A difficult and dangerous manoeuver and Dunning was later killed when his airplane was thrown overboard while attempting another landing on Furious . 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. Her funnel and superstructure remained intact however and turbulence from the funnel and superstructure

1969-422: A flat-top flight deck , which launches and 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

2148-404: 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. 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

2327-458: 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. They served the Royal Navy during the war, and the hull design was chosen for nearly all aircraft carrier equipped navies after

2506-643: A manned reconnaissance device that would give the viewer the advantage of considerable height. In 1908 Prime Minister H. H. Asquith approved the formation of an "Aerial Sub-Committee of the Committee of Imperial Defence " to investigate the potential for naval aviation. In 1909 this body accepted the proposal of Captain Reginald Bacon made to the First Sea Lord Sir John Fisher that rigid airships should be constructed for

2864-403: A more mobile strike capacity led to the development of the aircraft carrier - the backbone of modern naval aviation. HMS  Ark Royal was the first purpose-built seaplane carrier and was also arguably the first modern aircraft carrier. She was originally laid down as a merchant ship, but was converted on the building stocks to be a hybrid airplane/seaplane carrier with a launch platform and

3222-762: A naval zeppelin detachment in Berlin-Johannisthal and an airplane squadron in Putzig (Puck, Poland). The Japanese established the Imperial Japanese Navy Air Service , modelled on the RNAS , in 1913. On 24 January 1913 came the first wartime naval aviation interservice cooperation mission. Greek pilots on a seaplane observed and drew a diagram of the positions of the Turkish fleet against which they dropped four bombs. This event

3580-401: 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 carrier battle group . There is

3759-421: A place in modern asymmetric warfare , like the gunboat diplomacy of the past. Carriers also facilitate quick and precise projections of overwhelming military power into such local and regional conflicts. 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

3938-632: A platform extending from the side of the flight deck. In the United States, Admiral William Benson attempted to entirely dissolve the USN's Naval Aeronautics program in 1919. Assistant Secretary of the Navy Franklin Roosevelt and others succeeded in maintaining it, but the service continued to support battleship-based doctrines. To counter Billy Mitchell 's campaign to establish a separate Department of Aeronautics, Secretary of

4117-443: A platform extending from the side of the flight deck. In the United States, Admiral William Benson attempted to entirely dissolve the USN's Naval Aeronautics program in 1919. Assistant Secretary of the Navy Franklin Roosevelt and others succeeded in maintaining it, but the service continued to support battleship-based doctrines. To counter Billy Mitchell 's campaign to establish a separate Department of Aeronautics, Secretary of

4296-479: A relatively small area called an island , a feature pioneered on HMS  Hermes in 1923. While the island is usually built on the starboard side of the flight deck, the Japanese aircraft carriers Akagi and Hiryū had their islands built on the 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

4475-681: A seaplane carrier against a land target as well as a sea target took place in September 1914 when the Imperial Japanese Navy carrier Wakamiya conducted ship-launched air raids from Kiaochow Bay during the Battle of Tsingtao in China. The four Maurice Farman seaplanes bombarded German-held land targets (communication centers and command centers) and damaged a German minelayer in the Tsingtao peninsula from September until 6 November 1914, when

Based on these experiments, the Royal Navy concluded that aircraft were useful aboard ship for spotting and other purposes, but that interference with the firing of guns caused by

5191-421: A shorter runway length of the deck requires that aircraft 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

5370-482: 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 tons or greater, have become the pinnacle of carrier development. Some are powered by nuclear reactors and form

5549-501: A single medium-sized carrier. 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).

5728-412: 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

5907-459: A small number of aircraft. The solution to the problem were large numbers of mass-produced merchant hulls converted into escort aircraft carriers (also known as "jeep carriers"). These basic vessels, unsuited to fleet action by their capacity, speed and vulnerability, nevertheless provided air cover where it was needed. The Royal Navy had observed the impact of naval aviation and, obliged to prioritise their use of resources, abandoned battleships as

6265-528: A view among some military pundits 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. Carriers can also be vulnerable to diesel-electric submarines like the German U24 of the conventional 206 class which in 2001 "fired" at the Enterprise during

6444-560: Is a method of supplying naval vessels at sea, by helicopter . This means moving cargo and supplies from supply ships to the flight decks of other naval vessels using naval helicopters. During the Cold War , the navies of NATO faced a significant threat from Soviet submarine forces, specifically Soviet Navy SSN and SSGN assets. This resulted in the development and deployment of light aircraft carriers with major anti-submarine warfare (ASW) capabilities by European NATO navies. One of

6802-416: Is also used as part of amphibious warfare . Aircraft based on naval ships provide support to marines and other forces performing amphibious landings. Ship-based aircraft may also be used to support amphibious forces as they move inland. Naval aircraft are used for various maritime patrol missions, such as reconnaissance, search and rescue, and maritime law enforcement. Vertical replenishment (VERTREP)

7518-467: 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

7697-416: 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

7876-496: 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

8055-493: Is possible on a carrier deck, or assistance from a catapult or JATO rocket. For example, the Russian Sukhoi Su-33 is only able to launch from the carrier Admiral Kuznetsov 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

8234-455: Is sometimes combined with the aiming of jet thrust partly downward. 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

8413-723: Is the capital ship of a fleet (known as a carrier battle group ), 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

8592-414: Is the application of military air power by navies , whether from warships that embark aircraft, or land bases. It often involves navalised aircraft , specifically designed for naval use. Seaborne aviation encompasses similar activities not restricted to navies, including marines and coast guards , such as in U.S. naval aviators . Naval aviation units are typically projected to a position nearer

8771-567: The Doolittle Raid of 1942, 16 Army medium bombers were launched from the carrier Hornet on one-way missions to bomb Japan. All were lost to fuel exhaustion after bombing their targets and the experiment was not repeated. Smaller carriers were built in large numbers to escort slow cargo convoys or supplement fast carriers. Aircraft for observation or light raids were also carried by battleships and cruisers, while blimps were used to search for attack submarines. Experience showed that there

9845-619: The Turkish Straits between the Soviet Black Sea bases and the 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. Aircraft carriers today are usually divided into

10024-874: The United Kingdom and India each currently operate two STOBAR / STOVL aircraft carriers with ski-jump flight decks, with China in the process to commission a third carrier with catapult capabilities, and 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 also operated by Japan (4, two of which are being converted to operate V/STOL fighters), France (3), Australia (2, previously also owned 3 light carriers ), 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, Italy, Russia, South Korea, Turkey and

One of his pilots, Eugene Ely , took off from the cruiser USS  Birmingham anchored off the Virginia coast in November 1910. Two months later Ely landed aboard another cruiser, USS  Pennsylvania , in San Francisco Bay , proving the concept of shipboard operations. However, the platforms erected on those vessels were temporary measures. The U.S. Navy and Glenn Curtiss experienced two firsts during January 1911. On 27 January, Curtiss flew

12709-510: The Royal Navy's HMS  Ark Royal , that had a length of 800 feet (244 m), a displacement of 22,000 tons and was designed to carry 72 aircraft. Since then, aircraft carriers have consistently grown in size, both in length and displacement, as well as improved capabilities; in defense, sensors, electronic warfare, propulsion, range, launch and recovery systems, number and types of aircraft carried and number of sorties flown per day. China ( type 004 aircraft carrier ), France ( PANG ) and

By comparison, escort carriers 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

13604-508: The War. The first jet landing on a carrier was made by Lt Cdr Eric 'Winkle' Brown who landed on HMS  Ocean in the specially modified de Havilland Vampire ( registration LZ551/G) on 3 December 1945. Following the introduction of angled flight decks , jets were regularly operating from carriers by the mid-1950s. An important development of the early 1950s was the British invention of

14320-414: The aftermath of natural disasters. Naval aircraft are vital in cases where traditional infrastructure to provide relief are destroyed or overtaxed in the wake of a disaster, such as when a region's airport is destroyed or overcrowded and the region cannot be effectively accessed by road or helicopter. The capability of ships to provide clean, fresh water which can be transported by helicopter to affected areas

The capability of ships to provide clean, fresh water which can be transported by helicopter to affected areas

14678-462: 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. Helicopters 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

14857-474: The aircraft tows a sled through the water but is itself at a significant distance from the water, hopefully putting itself out of harm's way. Aircraft include the MH-53E and AW101 . Aircraft operated by navies are also used in the anti-surface warfare (ASUW or ASuW) role, to attack enemy ships and other, surface combatants . This is generally conducted using air-launched anti-ship missiles . Naval aviation

15573-489: The angled flight deck by Capt D.R.F. Campbell RN in conjunction with Lewis Boddington of the Royal Aircraft Establishment at Farnborough. The runway was canted at an angle of a few degrees from the longitudinal axis of the ship. If an aircraft missed the arrestor cables (referred to as a " bolter "), the pilot only needed to increase engine power to maximum to get airborne again, and would not hit

15931-538: 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,

16110-460: The capacity to hold up to four wheeled aircraft. Launched on 5 September 1914, she served in the Dardanelles campaign and throughout World War I. During World War I the Royal Navy also used HMS Furious to experiment with the use of wheeled aircraft on ships. This ship was reconstructed three times between 1915 and 1925: first, while still under construction, it was modified to receive

This ship was reconstructed three times between 1915 and 1925: first, while still under construction, it was modified to receive

16468-506: 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 nuclear reactors powering their systems and propulsion. The top of

16647-513: 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 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

16826-525: The case of merchant aircraft carriers , 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

17005-541: 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 USS ; Langley in 1922, the US Lexington -class aircraft carriers (1927), Japanese Akagi and Kaga , and British Courageous class (of which Furious

17184-648: The conversion of the collier USS Jupiter and its recommissioning as USS  Langley in 1922. Many British naval vessels carried float planes, seaplanes or amphibians for reconnaissance and spotting: two to four on battleships or battlecruisers and one on cruisers. The aircraft, a Fairey Seafox or later a Supermarine Walrus , were catapult-launched , and landed on the sea alongside for recovery by crane. Several submarine aircraft carriers were built by Japan, each carrying one floatplane, which did not prove effective in war. The French Navy built one large submarine , Surcouf , which also carried one floatplane, and

17542-453: The core of a fleet designed to operate far from home. Amphibious assault ships, such as the Wasp and Mistral classes, serve the purpose of carrying and landing Marines, and operate a large contingent of helicopters for that purpose. Also known as "commando carriers" or "helicopter carriers", many have the capability to operate VSTOL aircraft. The threatening role of aircraft carriers has

17721-474: The course of the war, seaborne aircraft were used in fleet actions at sea ( Midway , Bismarck ), strikes against naval units in port ( Taranto , Pearl Harbor ), support of ground forces ( Okinawa , Allied invasion of Italy ) and anti-submarine warfare (the Battle of the Atlantic ). Carrier-based aircraft were specialised as dive bombers , torpedo bombers , and fighters . Surface-based aircraft such as

18079-526: The cruiser Hermes converted into a seaplane carrier . In 1914, naval aviation was split again, and became the Royal Naval Air Service . However, shipboard naval aviation had begun in the Royal Navy, and would become a major part of fleet operations by 1917. Other early operators of seaplanes were Germany , within its Marine-Fliegerabteilung naval aviation units within the Kaiserliche Marine , and Russia . In May 1913 Germany established

18437-421: The deck of a United States Navy ship, the cruiser USS  Birmingham 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 armored cruiser USS  Pennsylvania 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

18616-467: The design of the carrier itself. There are two main philosophies 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: On the recovery side of the flight deck, the adaptation to the aircraft load-out

18795-417: The development and construction of 'light' carriers. Escort aircraft carriers , such as USS  Bogue , 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 (commissioned in 1943), represented

18974-547: The development of the optimum design for other aircraft carriers. Argus also evaluated various types of arresting gear , general procedures needed to operate a number of aircraft in concert, and fleet tactics. The Tondern raid , a British bombing raid against the Imperial German Navy 's airship base at Tønder , Denmark was the first attack in history made by aircraft flying from a carrier flight deck, with seven Sopwith Camels launched from HMS Furious .

For

19332-434: 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

19511-594: The exercise JTFEX 01-2 in the Caribbean Sea by firing flares and taking a photograph through its periscope or the Swedish Gotland which managed the same feat in 2006 during JTFEX 06-2 by penetrating the defensive measures of Carrier Strike Group 7 which was protecting USS  Ronald Reagan . 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

19690-593: The expensive connotations of the term "aircraft carrier", the Invincible -class carriers were originally designated as "through deck cruisers" and were initially to operate as helicopter-only craft escort carriers. The arrival of the Sea Harrier VTOL / STOVL fast jet meant that the Invincible-class could carry fixed-wing aircraft, despite their short flight decks. The British also introduced

20764-601: The first naval units solely destroyed by airplanes. During the war the German "Marineflieger" claimed the destruction of 270 enemy planes, 6 balloons, 2 airships, 1 Russian destroyer, 4 merchant ships, 3 submarines, 4 torpedo boats and 12 vehicles, for the loss of 170 German sea and land planes as well as 9 vehicles. Notable Marineflieger aces were Gotthard Sachsenberg (31 victories), Alexander Zenzes (18 victories), Friedrich Christiansen (13 victories, 1 airship and 1 submarine), Karl Meyer (8 victories), Karl Scharon (8 victories), and Hans Goerth (7 victories).

21480-777: The first successful catapult launch and arrested landing of an unmanned aerial vehicle (UAV) aboard an aircraft carrier. After a decade of research and planning, the US Navy has been testing the integration of UAVs with carrier-based forces since 2013, using the experimental Northrop Grumman X-47B , and is working to procure a fleet of carrier-based UAVs, referred to as the Unmanned Carrier Launched Airborne Surveillance and Strike (UCLASS) system. Naval aviation forces primarily perform naval roles at sea. However, they are also used for other tasks which vary between states. Common roles for such forces include: Carrier-based naval aviation provides

U.S. naval aviation began with pioneer aviator Glenn Curtiss who contracted with

22196-421: The flight deck and land vertically without the need for arresting gear. Carriers steam at speed, up to 35 knots (65 km/h; 40 mph) 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

22375-457: 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. 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. As "runways at sea", aircraft carriers have

22554-404: 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. The superstructure of a carrier (such as the bridge , flight control tower ) are concentrated in

22733-424: The flight deck. This was first developed to help launch 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

22912-454: The following four categories based on the way that aircraft take off and land: 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 The New York Times in 1938, in an article about

23091-412: 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

23270-492: The hydraulic catapults which had been introduced in the 1940s. The first Optical Landing System , the Mirror Landing Aid was invented by Lieutenant Commander H. C. N. Goodhart RN. The first trials of a mirror landing sight were conducted on HMS Illustrious in 1952. The US Navy built the first aircraft carrier to be powered by nuclear reactors . USS  Enterprise was powered by eight nuclear reactors and

23628-438: 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

23807-411: The loss of one man, the British destroyed two German zeppelins , L.54 and L.60 and a captive balloon. Genuine aircraft carriers did not emerge beyond Britain until the early 1920s. The Japanese Hōshō (1921) was the world's first purpose-built aircraft carrier, although the initial plans and laying down for HMS  Hermes (1924) had begun earlier. Both Hōshō and Hermes initially boasted

24523-569: The most effective weapons against submarines is the ASW helicopter, several of which could be based on these light ships. These carriers are typically around 20,000 tons displacement and carry a mix of ASW helicopters and fixed wing aircraft. Land-based maritime patrol aircraft are also useful in this role, since they can operate independently of aircraft carriers. Naval aircraft are used to airlift supplies, insert specialized personnel (e.g. medical staff, relief workers), and evacuate persons in distress in

24881-498: The need for land use authorizations from third-party countries, reduces the times and transit logistics of aircraft and therefore significantly increases the time of availability on the combat zone. There is no single definition of an "aircraft carrier", and modern navies use several variants of the type. These variants are sometimes categorized as sub-types of aircraft carriers, and sometimes as distinct types of aviation-capable ships. Aircraft carriers may be classified according to

25060-541: 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". 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

25239-598: The parked aircraft because the angled deck pointed out over the sea. The angled flight deck was first tested on HMS  Triumph , by painting angled deck markings onto the centerline flight deck for touch and go landings. The modern steam-powered catapult , powered by steam from a ship's boilers or reactors, was invented by Commander C.C. Mitchell of the Royal Naval Reserve . It was widely adopted following trials on HMS  Perseus between 1950 and 1952 which showed it to be more powerful and reliable than

25597-408: 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,

25776-660: The runway built over the foredeck and the danger and impracticality of recovering seaplanes that alighted in the water in anything but calm weather more than offset the desirability of having airplanes aboard. In 1912, the nascent naval air detachment in the United Kingdom was amalgamated to form the Royal Flying Corps and in 1913 a seaplane base on the Isle of Grain , an airship base at Kingsnorth and eight new airfields were approved for construction. The first aircraft participation in naval manoeuvres took place in 1913 with

26492-603: The sea and air supremacy . Since the Second World War , the aircraft carrier has replaced the battleship in the role of flagship of a fleet, and largely transformed naval battles from gun barrages to beyond-visual-range air strikes . In addition to tactical aptitudes, it has great strategic advantages in that, by sailing in international waters , it does not need to interfere with any territorial sovereignty and thus does not risk diplomatic complications or conflict escalation due to trespassing, and obviates

26671-494: 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

26850-523: 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 Nimitz class of US Navy carriers has a displacement nearly four times that of the World War II–era USS ; Enterprise , yet its complement of aircraft is roughly the same—a consequence of the steadily increasing size and weight of individual military aircraft over

27029-713: The target by way of an aircraft carrier . Carrier-based aircraft must be sturdy enough to withstand the demands of carrier operations. They must be able to launch in a short distance and be sturdy and flexible enough to come to a sudden stop on a pitching flight deck; they typically have robust folding mechanisms that allow higher numbers of them to be stored in below-decks hangars and small spaces on flight decks. These aircraft are designed for many purposes, including air-to-air combat , surface attack , submarine attack , search and rescue , matériel transport, weather observation , reconnaissance and wide area command and control duties. Naval helicopters can be used for many of

27208-425: The two most distinctive features of a modern aircraft carrier: a full-length flight deck and a starboard-side control tower island . Both continued to be adjusted in the light of further experimentation and experience, however: Hōshō even opted to remove its island entirely in favor of a less obstructed flight deck and improved pilot visibility. Instead, Japanese carriers opted to control their flight operations from

27566-456: The type of aircraft they carry and their operational assignments. Admiral Sir Mark Stanhope , RN, former First Sea Lord (head) of the Royal Navy , has said, "To put it simply, countries that aspire to strategic international influence have aircraft carriers." Henry Kissinger , while United States Secretary of State , also said: "An aircraft carrier is 100,000 tons of diplomacy." As of November 2024, there are 47 active aircraft carriers in

27745-462: The wake of the Tampico Affair . In January 1912, the British battleship HMS  Africa took part in aircraft experiments at Sheerness . She was fitted for flying off aircraft with a 100-foot (30 m) downward-sloping runway which was installed on her foredeck, running over her forward 12-inch (305 mm) gun turret from her forebridge to her bow and equipped with rails to guide

28103-402: 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

28282-583: The world operated by fourteen navies. The United States has 11 large nuclear-powered CATOBAR fleet carriers — each carrying around 80 fighters — the largest in the world, with the total combined deck space over twice that of all other nations combined. In addition, the US Navy has nine amphibious assault ships used primarily as helicopter carriers , although these also each carry up to 20 vertical/short takeoff and landing (V/STOL) jetfighters and are similar in size to medium-sized fleet carriers. China ,

28461-669: The world's first successful ship-launched air raid: 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. The first attack using an air-launched torpedo occurred on 2 August, when a torpedo was fired by Flight Commander Charles Edmonds from

28640-455: 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. Some changes were made after 1945 in carriers: Modern navies that operate such aircraft carriers treat them as capital ships of fleets, a role previously held by the galleons, ships-of-the-line and battleships . This change took place during World War II in response to air power becoming

28819-439: 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. In the " Doolittle Raid ", on 18 April 1942, the US Navy carrier USS  Hornet sailed to within 650 nautical miles (1,200 km) of Japan and launched 16 B-25 Mitchell medium bombers from her deck in

28998-476: Was a need for widespread use of aircraft which could not be met quickly enough by building new fleet aircraft carriers. This was particularly true in the North Atlantic , where convoys were highly vulnerable to U-boat attack. The British authorities used unorthodox, temporary, but effective means of giving air protection such as CAM ships and merchant aircraft carriers , merchant ships modified to carry

29356-562: Was also not effective in war. World War II saw the emergence of naval aviation as the decisive element in the war at sea. The principal users were Japan, United States (both with Pacific interests to protect) and Britain. Germany, the Soviet Union, France and Italy had a lesser involvement. Soviet Naval Aviation was mostly organised as land-based coastal defense force (apart from some scout floatplanes it consisted almost exclusively of land-based types also used by its air arms). During

During

29714-560: 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 launched a long-range strike on the Italian fleet at their base in Taranto , signalling

29893-415: Was management of the exhaust from the power plant. Fumes coming across the deck were a major issue in USS  Langley . 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. Another deck structure that can be seen is a ski-jump ramp at the forward end of

30072-746: Was not a complete success, owing to sub-optimal weather conditions, including fog and low cloud, but the raid was able to conclusively demonstrate the feasibility of air-to-land strikes from a naval platform. Two German airships were destroyed at the Tøndern base on July 19, 1918, by seven Sopwith Camels launched from the carrier HMS  Furious . In August 1914 Germany operated 20 planes and one Zeppelin, another 15 planes were confiscated. They operated from bases in Germany and Flanders (Belgium). On 19 August 1918 several British torpedo boats were sunk by 10 German planes near Heligoland. These are considered as

30430-656: Was one). 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 Hōshō (1922), HMS  Hermes (1924, although laid down in 1918 before Hōshō ), and Béarn (1927). During World War II , these ships would become known as fleet carriers . The aircraft carrier dramatically changed naval warfare in World War II, because air power

30609-471: Was seen as largely impractical at the time. CAPT Washington Irving Chambers felt it was much easier to defend against airplanes than mines or torpedoes. The wireless radio was cumbersome (greater than 50 pounds), but the technology was improving. Experiments were underway for the first ICS (pilot to observer comms) using headsets, as well as connecting the observer to the radio. The navy tested both telephones and voice tubes for ICS. As of August 1911, Italy

30967-478: Was severe enough that only three landing attempts were successful before further attempts were forbidden. This experience prompted the development of vessels with a flush deck and produced the first large fleet ships. In 1918, HMS  Argus became the world's first carrier capable of launching and recovering naval aircraft. As a result of the Washington Naval Treaty of 1922, which limited

31146-549: Was the only other navy known to be adapting hydroplanes for naval use. The group expanded with the addition of six aviators in 1912 and five in 1913, from both the Navy and Marine Corps , and conducted maneuvers with the Fleet from the battleship USS  Mississippi , designated as the Navy's aviation ship. Meanwhile, Captain Henry C. Mustin successfully tested the concept of the catapult launch in August 1912, and in 1915 made

31504-495: Was the second surface warship (after USS  Long Beach ) to be powered in this way. The post-war years also saw the development of the helicopter , with a variety of useful roles and mission capability aboard aircraft carriers and other naval ships. In the late 1950s and early 1960s, the United Kingdom and the United States converted some older carriers into Commando Carriers or Landing Platform Helicopters (LPH); seagoing helicopter airfields like HMS  Bulwark . To mitigate

At the outbreak of war the Royal Naval Air Service had 93 aircraft, six airships , two balloons and 727 personnel, making it larger than the Royal Flying Corps. The main roles of the RNAS were fleet reconnaissance, patrolling coasts for enemy ships and submarines, attacking enemy coastal territory and defending Britain from enemy air-raids, along with deployment along
