113-558: The Blackburn B-24 Skua was a carrier-based low-wing, two-seater, single- radial engine aircraft by the British aviation company Blackburn Aircraft . It was the first Royal Navy carrier-borne all-metal cantilever monoplane aircraft, as well as the first dive bomber in Fleet Air Arm (FAA) service. The aircraft took its name from the sea bird which 'divebombs' any potential predators that come too close to its nest. The Skua
226-557: A Dornier Do 18 flying boat over the North Sea . (An earlier victory by a Fairey Battle on 20 September 1939 over Aachen , was later confirmed by French sources). On 10 April 1940, 16 Skuas of 800 and 803 NAS led by Lieutenant Commander William Lucy, flying from RNAS Hatston in the Orkney Islands made a 330 mile night flight to arrive at the very limit of their radius - at dawn over Bergen Harbour. They attacked and sank
339-755: 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
452-518: 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
565-521: A fighter ace while flying his Skua. However, as the war intensified, the Skua was found to be too slow and under powered to be an effective fleet defence fighter. Common Axis foes such as the Junkers Ju 88 and Savoia-Marchetti SM.79 were significantly faster than the Skua, making interception of these aircraft extremely difficult. Also its armament of four forward firing .303 rifle caliber machine guns
678-421: A hydraulic damping device was incorporated in the hook. The mainplane, both the structure and covering of which was also composed of Alclad, was built as three separate units. The twin-spar heavy centre section was bolted beneath the fuselage to form the bottom of the watertight compartment. The outer wing panels, which tapered in both plan and thickness, ended in detachable upswept tips and were sealed between
791-405: 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
904-429: A compartment within the rear decking when not in use. Various key elements of the aircraft were housed between the pilot and gunner's positions. A wireless compartment was positioned directly behind the pilot. The majority of the fuel was stored in two tanks positioned between the crew members, with a reserve tank in the forward fuselage; the pilot could select for fuel to be drawn from any combination of these tanks via
1017-550: 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
1130-412: 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
1243-425: A fighter. Blackburn chose to produce its own response under the internal design reference B-24 , the design effort was headed by the aeronautical engineer G. E. Petty. Many competing companies also responded, including Avro , Boulton Paul , Hawker and Vickers . Blackburn's submission would emerge as the victor, despite several of the competing proposals adopting similar layouts. Being Blackburn's first dive bomber,

#17327728858511356-422: 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
1469-404: 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
1582-458: 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

Aircraft carrier An aircraft carrier
1808-401: 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
1921-421: 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
2034-410: A portion of the tailplane and the entirety of the fabric-covered elevator was positioned behind the trailing edge of the rudder. The crew were accommodated beneath an enclosed glazed cockpit enclosure strengthened by two fuselage frames that formed a crash pylon in the event of the aircraft turning over. It was the Fleet Air Arm 's first service monoplane and was a radical departure for a force that
2147-461: A relatively large fuel capacity, watertight compartments, rafts, and a rear gunner/observer. That weight, coupled with the limited power from the 890 hp (660 kW) Perseus engine, meant the aircraft had a low rate of climb compared to contemporary Japanese Mitsubishi A5M and American Grumman F3F carrier-borne fighters along with the Royal Navy's Gloster Sea Gladiator . The Skua was designed for best performance at low altitude, where its speed
2260-479: 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
2373-571: A result of this error the weapons detonated almost instantaneously, thus badly damaging the Skuas. U-30 returned to Germany with the crews of the two ditched Skuas, who became the first naval airmen to be prisoners of war in the conflict. Skuas were originally credited with the first confirmed kill by British aircraft during the Second World War : on 26 September 1939, three Skuas of 803 Naval Air Squadron , flying from Ark Royal , shot down
SECTION 20
#17327728858512486-403: A retractable undercarriage and folding wings; the solution drew on the earlier Blackburn Airedale monoplane. When folded, the wings moved back around an inclined hinge housed within the wing, enabling a twist in the movement so that they rest against the fuselage; latch pins were used to secure them in place. The main undercarriage retracted both outwards and upwards into circular wheel wells in
2599-421: 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
2712-482: 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
2825-501: 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). Kalaat Béni Abbès (L-474)
2938-520: A single selector cock. Just forward of the pilot's instrumentation was a tank for lubricating oil . The aircraft's armament of four fixed, forward-firing 0.303 in Browning machine guns in the wings and a single flexible, rearward-firing .303 in Vickers K machine gun was considered to be effective for the era. For the dive-bombing role, a 250 lb (110 kg) or 500 lb (230 kg) bomb
3051-412: 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
3164-528: 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
3277-759: Is a shore base of the Royal Navy in Gosport , Hampshire , England. It is the primary engineering training establishment for the Royal Navy and home to the Network Rail Advanced Apprenticeship Scheme and the EDF Energy engineering maintenance apprenticeship. The site was originally RAF Gosport it was then transferred to the Royal Navy during 1945 as HMS Siskin (Hence a nearby school being named Siskin School) it
3390-458: Is a warship that serves as a seagoing airbase , equipped with a full-length flight deck and hangar facilities for supporting, arming, deploying and recovering shipborne aircraft . Typically it is the capital ship of a fleet (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
3503-649: Is an amphibious transport dock of the Algerian National Navy with two deck-landing spots for helicopters. The Royal Australian Navy operates two Canberra -class landing helicopter docks . The two-ship class, based on the Spanish vessel Juan Carlos I and built by Navantia and BAE Systems Australia , represents the largest ships ever built for the Royal Australian Navy.

3616-467: 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
3729-416: 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
3842-496: 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
3955-493: 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
4068-455: 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
4181-683: The Admiralty Interview Board to HM Naval Base Portsmouth in 2026. In March 2019, the Ministry of Defence announced that closure would be delayed to 2029 at the earliest. However, in December 2022, the Ministry of Defence announced that the closure had been reversed and HMS Sultan was to remain open. An MOD spokesperson said: "We can confirm that we are retaining HMS Sultan for which we have an enduring requirement." The following units were also posted here at some point: It
4294-684: The Battles of Narvik , the Dunkirk evacuation and also the early stages of the Mediterranean theatre. While a capable dive bomber, its poor top speed and rate of climb meant it was severely limited as a fighter aircraft. Despite this, Fleet Air Arm pilots achieved moderate success with the Skua, scoring numerous aerial victories during the Norwegian and Mediterranean campaigns, with at least one pilot making ace status with five victories. In 1941,
4407-551: The Bristol Perseus XII , largely due to the Mercury engine being prioritised for Bristol Blenheim production. Another change made on production aircraft was the elimination of the wing tip slots, as they were deemed unnecessary after handling tests revealed mild stall characteristics. Due to the growing urgency for more combat aircraft in the runup to the Second World War , an initial production contract for 190 Skuas
4520-417: The Dunkirk evacuation , acting as a unit of RAF Fighter Command . However, these Skuas were attacked on several occasions by RAF fighters who were unfamiliar with the aircraft and its paint scheme, with at least one aircraft being shot up by Spitfires and the gunner killed. It was to later crash land at Manston airfield. Following replenishment, Ark Royal brought along a flight of Skuas on its deployment into
4633-592: The German cruiser Königsberg with several direct hits. Jackson wrote of the sinking as being the highpoint of the Skua's career as a dive-bomber. Königsberg was the first major warship ever sunk in war by air attack and the first major warship ever to be sunk by dive bombing. On 26 and 27 April Skuas destroyed eight He 111 bombers and damaged several more whilst defending the fleet. During June 1940, Skuas of 801 Squadron flew from shore bases in Kent in support of

4746-619: 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
4859-874: 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

The first landing of an airplane on a moving ship was by Squadron Commander Edwin Harris Dunning , when he landed his 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,
5198-824: The Mediterranean later that year; it was these Skuas that dive-bombed the Richelieu in Dakar in September 1940. On 13 June 1940, two mostly-Skua squadrons suffered heavy losses during an attempt to bomb the Scharnhorst at Trondheim ; of 15 aircraft in the raid, eight were shot down and the crews killed or taken prisoner. Among the latter were both squadron commanders, Captain RT Partridge (RM) and Lieutenant Commander John Casson (RN). One bomb hit Scharnhorst ; however, this did little damage. Despite its limitations,
5311-510: 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
5424-414: The Skua attained considerable success as a fighter against Axis bombers and flying boats over Norway, and to a lesser extent, in the Mediterranean in the early stages of the conflict. In action off Norway Skuas destroyed 28 Luftwaffe aircraft in air to air combat, including 17 He 111s and five Ju 88s; all kills being confirmed via Luftwaffe records. Lieutenant Commander William Lucy went on to become
5537-421: The Skua matched up well with the best of these as regards to its diving characteristics, but it had only a two-position propeller and this tended to overspeed in the dive before terminal velocity was reached. However, a nicely screaming propeller was always to be considered a psychologically aggressive asset in any dive bomber." During late 1938, initial deliveries of the Skua commenced; the first unit to receive it
5650-464: The Skua was relegated from frontline operations, but continued to be operated in secondary roles, typically training and target tug duties, as late as March 1945. The origins of the Skua can be traced back to the Air Ministry 's issuing of Specification O.27/34 , which sought a naval dive bomber whose primary role would be to disable or destroy enemy aircraft carriers with a secondary role as
5763-622: The Skua's 225 mph (362 km/h), and the Gloster Sea Gladiator's 209 mph (336 km/h). However the Skua in the fighter role was never intended or envisaged to take on land-based fighters such as the Messerschmitt Bf 109. The Royal Navy and RAF (who at the time its specification was drawn up operated aircraft carrier air wings) only intended the aircraft to take on enemy reconnaissance and bomber aircraft. The Skua was, however, an effective dive bomber, which

#17327728858515876-711: The United Kingdom all have carriers in service or under construction with displacements ranging from 65,000 to 85,000 tons and lengths from 280 to 320 meters (920 to 1,050 ft) which have been described as "supercarriers". The largest "supercarriers" in service as of 2022, however, are with the US Navy, with displacements exceeding 100,000 tons, lengths of over 337 meters (1,106 ft), and capabilities that match or exceed those of any other class. Several systems of identification symbol for aircraft carriers and related types of ship have been used. These include

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, 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
6102-529: The aid of the Fanad Head which had been attacked by a U-boat . When they arrived, the Fanad Head was being shelled by the German submarine U-30 and all three dived to attack the submarine, which quickly dived to safety. Two of the Skuas were damaged by the blast of their 112 lb A/S bombs and had to ditch. This was due to that the bombs had been wrongly fused with too brief a time lapse. As
6215-462: 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
6328-538: 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,
6441-506: 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

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
6667-525: 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

7119-557: The design of the Blackburn Shark , an earlier biplane, making extensive use of flush- riveted Alclad . It was internally divided into two water-tight compartments beneath the pilot's and gunner's cockpits to provide sufficient buoyancy in the event of a forcing landing at sea. For the same reason, the crew compartments were also watertight up to the edges of the cockpit. The fuselage was stressed to withstand catapult-assisted takeoffs and arrested landings aboard aircraft carriers;
7232-467: 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

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
7571-434: 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

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

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

8701-424: 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
8814-454: 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
8927-412: 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
9040-438: 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
9153-401: The main spars to form additional watertight compartments. Recesses in the lower surface of the wing accommodated modified Zap flaps that were used to shorten takeoff runs, steepen glides, and limit the aircraft's speed during steep dives. Balanced ailerons were fitted, which used inset hinges with mass balance assistance. Considerable design complexity was incurred by the choice to have both
9266-498: 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
9379-541: 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
9492-408: 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,
9605-537: 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
9718-494: 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
9831-473: The second production aircraft were dispatched to Martlesham to accelerate the last stage of performance trials, which included armament trials. According to the aviation author Aubrey Joseph Jackson, despite the relatively radical nature of the design, relatively few changes were recommended either by the Air Ministry or the engine manufacturer; one of the few modifications requested was the strengthening of
9944-494: The second prototype performed its first flight; it differed from the first by having a longer nose. Both of the prototypes would participate in the various tests, including gunnery trials, that were performed at Martlesham up until early 1939. Ditching trials were also undertaken at RAF Gosport . Both prototypes were powered by the Bristol Mercury XII radial engine; however, production Skuas were instead powered by
10057-523: 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
10170-482: The two-seat aircraft, and the extra strengthening of the air frame required to allow it to withstand the stresses of sustained high-speed dives, meant it was a relatively heavy single-engined aircraft at 8,300 lb (3,800 kg) gross, compared to 5,900 lb (2,700 kg) for the Spitfire Mk1. That was compounded by various features included to suit its naval use, such as an arrester hook , folding wings,
10283-456: 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
10396-452: The underside of the outer wing panels, the motion being powered by an engine-driven hydraulic pump. The tail wheel unit was fitted with a Dowty -supplied self-centering shock absorber strut and an electrically conductive tyre . Both tailplane and fin were metal-clad cantilever structures that bolted directly onto the rear frames of the fuselage. Controllable trim tabs and a horn-balanced rudder were fitted, to ensure rapid spin recovery,
10509-402: 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
10622-554: The wingtips and a substitute tail oleo . Almost all of the production run was completed and delivered prior to the end of 1939, 26 Skuas were delivered during the month of July alone. However, due to delays in the overall programme, the Admiralty had also ordered the Fairey Fulmar to perform the same role. The Blackburn Skua was configured as a low-wing cantilever monoplane of all-metal construction. Its fuselage drew on
10735-583: 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 ,
10848-669: 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
10961-455: 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
11074-505: Was 800 Naval Air Squadron at Worth Down, supplementing and eventually replacing their Hawker Nimrod and Hawker Osprey biplanes. By November, the squadron had embarked on HMS Ark Royal and, during 1939, was followed by both 801 and 803 Squadrons. By the start of the Second World War, there were 33 operational Skuas; the type quickly proved itself in combat. On 14 September, three Skuas took off from Ark Royal to go to
11187-439: 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
11300-462: Was arguably its main intended role. It scored numerous successes as a dive bomber in the Norwegian campaign, sinking and damaging a number of ships, most notably the German cruiser Königsberg on 10 April 1940. Royal Navy test pilot Captain Eric 'Winkle' Brown stated: "It was while diving that the Skua really came into its own...subsequently I was to fly quite a number of US and German dive bombers and
11413-616: 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
11526-426: Was becoming increasingly inadequate for this role. Thus the type was withdrawn from front line service during 1941. Most Skuas were replaced by another two-seater, the Fairey Fulmar , which doubled the Skua's forward armament and had a speed advantage of 50 mph (80 km/h). A number of aircraft were converted to target tugs , following withdrawal from front line service. Others were completed as target tugs from
11639-402: Was carried on a special swinging "trapeze" crutch under the fuselage (somewhat like that of the Junkers Ju 87 ), which enabled the bomb to clear the propeller arc on release. Four 40 lb (18 kg) bombs or eight 20 lb (9.1 kg) Cooper bombs could also be carried in racks under each wing. Its performance as a fighter was compromised by its dual role as a dive bomber. The size of
11752-565: Was comparable to potential enemy bomber aircraft, and the Skua, with four wing-mounted Browning machine guns, was much better armed than any other nation's pre-war naval fighter, such as the Mitsubishi A5M "Claude" and the Grumman F3F, having only two machine guns each. All those naval fighters compared unfavourably with land-based fighters such as the Messerschmitt Bf 109 , which reached 290 mph (470 km/h) at sea level over
11865-473: Was designed during the mid-1930s to Specification O.27/34 , and was a radical design for the era, combining the functions of a dive bomber and fighter . Its enclosed cockpit and monoplane configuration were obvious shifts from preceding FAA aircraft such as the Hawker Nimrod and Hawker Osprey biplanes. On 9 February 1937, the first prototype performed its maiden flight ; it was ordered straight off
11978-540: Was discovered in Orkdalsfjorden in Norway at 242 metres (794 ft) depth. Due to an engine failure, the Skua, flown by John Casson, leader of 803 Squadron, had to make an emergency water landing in the fjord. Both crew members survived and spent the next five years as prisoners of war. Despite efforts to raise the aircraft to the surface as gently as possible, the tail broke off. The engine had become detached in
12091-531: Was first displayed to the public at RAF Hendon , London , and performed an aerial display at RAF Hatfield Woodhouse two days later. Two months later, the Skua name was officially assigned to the type by the Air Ministry. During the latter part of 1937, the aircraft underwent official handling trials with the Aeroplane and Armament Experimental Establishment (A&AEE) at RAF Martlesham Heath . On 4 May 1938,
12204-576: Was issued in July 1935, effectively being ordered straight from the drawing board. To accelerate production, it was decided to produce the mainplanes at the Olympia Works in Leeds , while a subcontracting arrangement with General Aircraft Limited saw this company build additional fuselages at its Hanworth facility. On 28 August 1938, the first production Skua Mk.II, L2867 , performed its first flight at Brough, piloted by H. J. Wilson. Both it and
12317-415: 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
12430-656: 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
12543-465: Was primarily equipped with open-cockpit biplanes such as the Fairey Swordfish . The pilot's position featured a sliding hood and was provided with favourable visibility in most forward-facing directions, while the gunner was seated after of the wing beneath a tilting canopy that could be opened or closed dependent on whether the defensive gun was being operated. This machine gun was stored in
12656-478: 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
12769-605: Was then renamed HMS Sultan on 1 June 1956 when the airfield side was closed down and a Mechanical Repair Establishment was moved here from the Flathouse area by Portsmouth Dockyard . A Better Defence Estate , published in November 2016, indicated that the Ministry of Defence intended on disposing of HMS Sultan by 2026. It was proposed that Submarine Engineer Training would move to HM Naval Base Clyde in 2024, Mechanical Engineering Training to HMS Collingwood in 2025 and
