152-544: The Vertical Flight Society , formerly the American Helicopter Society ( AHS ), is the non-profit technical society for the advancement of vertical flight. It has 21 different technical committees and two dozen active chapters around the world. There are over 100 corporate members and 28 educational members. Each year, the Society organizes or co-sponsors several regional and international conferences that facilitate
304-617: A LITENING targeting pod to perform reconnaissance missions along with attack and other missions, primarily at night. The aircraft participated in the Iraq War in 2003, acting primarily in support of USMC ground units. During the initial action, 60 AV-8Bs were deployed on ships such as USS Bonhomme Richard and Bataan , from which over 1,000 sorties were flown throughout the war. When possible, land-based forward arming and refueling points were set up to enable prompt operations. USMC commander Lieutenant General Earl B. Hailston said that
456-717: 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
608-509: 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
760-522: A forward-looking infrared (FLIR) camera added to the top of the nose cone, a wide Smiths Industries head-up display (HUD), provisions for night vision goggles , and a Honeywell digital moving map system. The FLIR uses thermal imaging to identify objects by their heat signatures. The variant was powered by the F402-RR-408 engine, which featured an electronic control system and was more powerful and reliable. The flare and chaff dispensers were moved, and
912-527: A 21,450 lbf (95.4 kN) F402-RR-406A engine, while later examples were fitted with the 23,000 lbf (105.8 kN) F402-RR-408A. In the early 2000s, 17 TAV-8Bs were upgraded to include a night-attack capability, the F402-RR-408 engine, and software and structural changes. Fielded in 1991, the Night Attack Harrier was the first upgrade of the AV-8B. It differed from the original aircraft in having
1064-405: 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
1216-583: A contract for eight aircraft. Production of the AV-8B Harrier II Plus was conducted, in addition to McDonnell Douglas' plant, at CASA 's facility in Seville , Spain, and Alenia Aeronautica 's facility in Turin , Italy. The UK also participated in the program by manufacturing components for the AV-8B. Production was authorized on 3 June 1992. The maiden flight of the prototype took place on 22 September, marking
1368-545: 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
1520-412: 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
1672-422: 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
SECTION 10
#17330848602701824-569: A high mission-capable rate of 91.8%. On 28 April, the 24th MEU was relieved by the 26th MEU, based on USS Kearsarge . The first combat sorties of the unit's AV-8Bs occurred two days later, one aircraft being lost. The 26th MEU remained in the theater of operations until 28 May, when it was relocated to Brindisi , Italy. USMC AV-8Bs took part in Operation Enduring Freedom in Afghanistan from 2001. The USMC 15th MEU arrived off
1976-404: 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
2128-458: 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
2280-565: A larger, more powerful Pegasus engine to dramatically improve the capabilities of the Harrier. Because of budgetary constraints, the UK abandoned the project in 1975. Following the UK's withdrawal, McDonnell Douglas extensively redesigned the earlier AV-8A Harrier to create the AV-8B. While retaining the general layout of its predecessor, the aircraft incorporates a new, larger composite wing with an additional hardpoint on each side, an elevated cockpit ,
2432-624: A lower cost than manufacturing new ones. Conversion began in April 1994, and the first aircraft was delivered to the USMC in January 1996. In March 1996, the U.S. General Accounting Office (GAO) stated that it was less expensive to buy Harrier II Plus aircraft outright than to remanufacture existing AV-8Bs. The USN estimated the cost for remanufacture of each aircraft to be US$ 23–30 million, instead of $ 30 million for each new-built aircraft, while
2584-401: 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
2736-421: 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
2888-595: A private venture, BAe, McDonnell Douglas, and Smiths Industries agreed on the development of what was to become the AV-8B Plus with the addition of radar and increased missile compatibility. The agreement was endorsed by the USMC and, after much consideration, the Spanish and Italian navies developed a joint requirement for a fleet of air-defense Harriers. The United States, Spain, and Italy signed an MoU in September 1990 to define
3040-504: A procurement of 12 aircraft initially, followed by a further 324. Between 1978 and 1980, the DoD and USN repeatedly attempted to terminate the AV-8B program. There had previously been conflict between the USMC and USN over budgetary issues. At the time, the USN wanted to procure A-18s for its ground attack force and, to cut costs, pressured the USMC to adopt the similarly designed F-18 fighter instead of
3192-566: A redesigned fuselage and other structural and aerodynamic refinements. The aircraft is powered by an upgraded version of the Pegasus. The AV-8B made its maiden flight in November 1981 and entered service with the USMC in January 1985. Later upgrades added a night-attack capability and radar, resulting in the AV-8B(NA) and AV-8B Harrier II Plus versions, respectively. An enlarged version named Harrier III
SECTION 20
#17330848602703344-474: 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
3496-576: A revised inlet. On the underside of the fuselage, McDonnell Douglas added lift-improvement devices, which capture the reflected engine exhaust when close to the ground, giving the equivalent of up to 1,200 lb (544 kg) of extra lift. The technological advances incorporated into the Harrier II, compared with the original Harrier, significantly reduce the workload on the pilot. The supercritical wing , hands-on-throttle-and-stick (HOTAS) control principle, and increased engineered lateral stability make
3648-421: 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
3800-482: 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
3952-480: A single incident since the Vietnam War ." The lost aircraft were quickly replaced by those from VMA-231 . On 27 July 2014, USS Bataan began deploying USMC AV-8Bs over Iraq to provide surveillance of Islamic State (IS) forces. Surveillance operations continued after the start of Operation Inherent Resolve against IS militants. In early September 2014, a USMC Harrier from the 22nd MEU struck an IS target near
4104-501: 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)
4256-412: 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
4408-468: A subcontractor, instead of the full partner status that would have been the case had the UK not left the program. Consequently, the company received, in man-hours, 40% of the airframe work-share. Aircraft production took place at McDonnell Douglas' facilities in suburban St. Louis , Missouri , and manufacturing by BAe at its Kingston and Dunsfold facilities in Surrey , England. Meanwhile, 75% work-share for
4560-475: A two-tone matte gray finish, similar to U.S. Navy aircraft, and deliveries were complete by 1988. BAe test pilots cleared the aircraft carrier Príncipe de Asturias for Harrier operations in July 1989. The carrier, which replaced the World War II-era Dédalo , has a 12° ski-jump ramp . It was originally planned that the first unit to operate the aircraft would be the 8 Escuadrilla . This unit
4712-454: A variant tailored to the RAF, uses different avionics and has one additional missile pylon on each wing. The Harrier II retains the tandem landing gear layout of the first-generation Harriers, although each outrigger landing gear leg was moved from the wingtip to mid-span for a tighter turning radius when taxiing . The engine intakes are larger than those of the first-generation Harrier and have

4864-516: 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
5016-425: A wide range of functions, including radar warning information and weapon delivery checklist. The pilots sit on UPC/Stencel 10B zero-zero ejection seats , meaning that they are able to eject from a stationary aircraft at zero altitude. For the AV-8B, McDonnell Douglas redesigned the entire airframe of the Harrier, incorporating numerous structural and aerodynamic changes. To improve visibility and better accommodate
5168-415: Is 7,500 lb (3,400 kg), up 50% compared to its predecessor. Fuel capacity can be carried in hardpoint-compatible external drop tanks , which give the aircraft a maximum ferry range of 2,100 mi (3,300 km) and a combat radius of 300 mi (556 km). The AV-8B can also receive additional fuel via aerial refueling using the probe-and-drogue system. The British Aerospace Harrier II,
5320-577: Is a single-engine ground-attack aircraft that constitutes the second generation of the Harrier family, capable of vertical or short takeoff and landing (V/STOL). The aircraft is primarily employed on light attack or multi-role missions, ranging from close air support of ground troops to armed reconnaissance . The AV-8B is used by the United States Marine Corps (USMC), the Spanish Navy , and
5472-467: 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
5624-416: 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
5776-496: 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
5928-484: 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
6080-436: Is powered by a single Rolls-Royce Pegasus turbofan engine, which has two intakes and four synchronized vectorable nozzles close to its turbine. Two of these nozzles are located near the forward, cold end of the engine and two are near the rear, hot end of the engine. This arrangement contrasts with most fixed-wing aircraft, which have engine nozzles only at the rear. The Harrier II also has smaller valve-controlled nozzles in
6232-548: Is reported to have shot down seven Houthi suicide attack drones. In the late 1960s, following a demonstration of the Hawker Siddeley Harrier on the Italian Navy ( Marina Militare ) helicopter carrier Andrea Doria , the country began investigating the possibility of acquiring the Harrier. Early efforts were hindered by a 1937 Italian law that prohibited the navy from operating fixed-wing aircraft because they were

6384-400: 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
6536-723: 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
6688-586: Is to be replaced by the F-35B version of the Lockheed Martin F-35 Lightning II , which was planned to enter service in 2012. The USMC had sought a replacement since the 1980s and has argued strongly in favor of the development of the F-35B. The Harrier's performance in Iraq, including its ability to use forward operating bases, reinforced the need for a V/STOL aircraft in the USMC arsenal. In November 2011,
6840-559: The F-16 Fighting Falcon 's APG-66 radar. A Taiwanese purchase would have allowed the production line to stay open beyond 2005. Despite the possibility of leasing AV-8Bs, interest in the aircraft waned as the country switched its intentions to procuring the F-35 and upgrading its fleet of F-16s. Although there have been no new AV-8B variants, in 1990 McDonnell Douglas and British Aerospace began discussions on an interim aircraft between
6992-685: The Haditha Dam in Iraq, marking the first time a USMC unit dropped ordnance in the operation. On 1 August 2016, USMC Harriers from USS Wasp began strikes against ISIL in Libya as part of manned and unmanned airstrikes on targets near Sirte , launching at least five times within two days. In January 2024 during the Red Sea crisis one of the Harriers was modified for air defense; its pilot Captain Earl Ehrhart
7144-687: The Italian Navy . A variant of the AV-8B, the British Aerospace Harrier II , was developed for the British military, while another, the TAV-8B, is a dedicated two-seat trainer . The project that eventually led to the AV-8B's creation started in the early 1970s as a cooperative effort between the United States and United Kingdom, aimed at addressing the operational inadequacies of the first-generation Hawker Siddeley Harrier . Early efforts centered on
7296-596: 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
7448-867: 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
7600-518: The pennant numbers used by the Royal Navy, Commonwealth countries, and Europe, along with the hull classification symbols used by the US and Canada . The 1903 advent of the heavier-than-air fixed-wing airplane with the Wright brothers ' first flight at Kitty Hawk, North Carolina , was closely followed on 14 November 1910, by Eugene Burton Ely 's first experimental take-off of a Curtiss Pusher airplane from
7752-575: The ram-air intake was lengthened at the fin's base. Initially known as the AV-8D, the night-attack variant was designated the AV-8B(NA). The Harrier II Plus is very similar to the Night Attack variant, with the addition of an APG-65 multi-mode pulse-Doppler radar in an extended nose, allowing it to launch advanced beyond-visual-range missiles such as the AIM-120 AMRAAM. To make additional space for

#17330848602707904-417: The 1990s, Boeing and BAE Systems assumed management of the Harrier family following corporate mergers that saw Boeing acquire McDonnell Douglas and BAe acquire Marconi Electronic Systems to form BAE Systems. Between 1969 and 2003, 824 Harriers of all models were delivered. In 2001, Flight International reported that Taiwan might meet its requirement for a V/STOL aircraft by purchasing AV-8Bs outfitted with
8056-582: The AV-16 effort, though dropping some items—such as the larger Pegasus engine—McDonnell Douglas kept the basic structure and engine for an aircraft tailored for the USMC. As the USMC wanted a substantially improved Harrier without the development of a new engine, the plan for Harrier II development was authorized by the United States Department of Defense (DoD) in 1976. The United States Navy (USN), which had traditionally procured military aircraft for
8208-499: The AV-8's payload and range and was therefore unofficially named AV-16. The British government pulled out of the project in March 1975 owing to decreased defense funding, rising costs, and the RAF's insufficient 60-aircraft requirement. With development costs estimated to be around £180–200 million (1974 British pounds), the United States was unwilling to fund development by itself and ended
8360-554: The AV-8A (American designation for the Harrier) carried less than half of the smaller A-4 Skyhawk 's payload (4,000 lb (1,800 kg), over a more limited radius. To address this, Hawker Siddeley and McDonnell Douglas began joint development of a more capable version of the Harrier in 1973. Early efforts concentrated on an improved Pegasus engine, designated the Pegasus 15, which was being tested by Bristol Siddeley . Although more powerful,
8512-553: The AV-8B among the seven weapons—along with the F-117 Nighthawk and AH-64 Apache —that played a crucial role in the war. In the aftermath of the war, from 27 August 1992 until 2003, USMC AV-8Bs and other aircraft patrolled Iraqi skies in support of Operation Southern Watch . The AV-8Bs launched from amphibious assault ships in the Persian Gulf and from forward operating bases such as Ali Al Salem Air Base , Kuwait. In 1999,
8664-469: The AV-8B and the next generation of advanced V/STOL aircraft. The Harrier III would have presented an "evolutionary approach to get the most from the existing aircraft", as many of the structures employed on the Sea Harrier and AV-8B would be used. The wing and the torsion box were to be enlarged to accommodate extra fuel and hardpoints to improve the aircraft's endurance. Because of the increase in size,
8816-524: The AV-8B is the TAV-8B, seating two pilots in tandem. Among other changes, the forward fuselage features a 3 ft 11 in (1.19 m) extension to accommodate the second cockpit. To compensate for the slight loss of directional stability, the vertical stabilizer's area was enlarged through increases in chord (length of the stabilizer's root) and height. USMC TAV-8Bs feature the AV-8B's digital cockpit and new systems but have only two hardpoints and are not combat capable. Initial TAV-8Bs were powered by
8968-441: The AV-8B is to receive revamped defensive measures, updated data-link capability and targeting sensors, and improved missiles and rockets, among other enhancements. The AV-8B Harrier II is a subsonic attack aircraft of metal and composite construction that retains the basic layout of the Hawker Siddeley Harrier, with horizontal stabilizers and shoulder-mounted wings featuring prominent anhedral (downward slope). The aircraft
9120-454: The AV-8B participated in NATO's bombing of Yugoslavia during Operation Allied Force . Twelve Harriers were split evenly between the 24th and 26th Marine Expeditionary Units (MEU). AV-8Bs of the 24th MEU were introduced into combat on 14 April and over the next 14 days flew 34 combat air support missions over Kosovo. During their six-month deployment aboard USS Nassau , 24th MEU Harriers averaged
9272-754: The AV-8B to fly both deep and close air support missions (deep air support missions do not require coordination with friendly ground forces) in concert with other close-support aircraft, as well as flying battlefield interdiction and armed reconnaissance missions. The aircraft flew from military installations at Marine Corps Base Camp Pendleton and Naval Air Weapons Station China Lake in California; Canadian Forces Base Cold Lake in Canada; and Marine Corps Air Station Yuma in Arizona.

#17330848602709424-407: The AV-8B to fulfill the role of close air support (both designs were eventually amalgamated to create the multirole F/A-18 Hornet ). Despite these bureaucratic obstacles, in 1981 the DoD included the Harrier II in its annual budget and five-year defense plan. The USN declined to participate in the procurement, citing the limited range and payload compared with conventional aircraft. In August 1981,

Although the evaluation identified shortfalls in the design (subsequently rectified), OPEVAL was deemed successful. The AV-8B Harrier II reached initial operating capability (IOC) in January 1985 with USMC squadron VMA-331 . The AV-8B saw extensive action in the Gulf War of 1990–91. Aircraft based on USS Nassau and Tarawa , and at on-shore bases, initially flew training and support sorties , as well as practicing with coalition forces. The AV-8Bs were to be held in reserve during

However, by 2014 the USMC had decided to retire the AV-8B sooner because changing the transition orders of Harrier II and Hornet fleets to the Lightning II would save $ 1 billion (~$ 1.27 billion in 2023). The F-35B began replacing the AV-8B in 2016, with the AV-8B expected to continue service until 2025. Meanwhile,
10032-504: The GAO estimated the cost per new aircraft at $ 24 million. Nevertheless, the program continued and, in 2003, the 72nd and last AV-8B to be remanufactured for the USMC was delivered. Spain also participated in the program, the delivery of its last refurbished aircraft occurring in December 2003, which marked the end of the AV-8B's production; the final new AV-8B had been delivered in 1997.

The aircraft, equipped with LGBs, operated throughout January and February 2002, during which 131 missions were logged for a total of 647 flight hours. In 2011, Italian Harriers, operating from Giuseppe Garibaldi , worked alongside Italian Typhoons and aircraft of other nations during Operation Unified Protector , part of the 2011 military intervention in Libya . They conducted airstrikes as well as intelligence and reconnaissance sorties over Libya, using

In total, Italian military aircraft delivered 710 guided bombs and missiles during sorties: Italian Air Force Tornados and AMX fighter bombers delivered 550 bombs and missiles, while the eight Italian Navy AV-8Bs flying from Giuseppe Garibaldi dropped 160 guided bombs during 1,221 flight hours. Italian Navy AV-8Bs are slated to be replaced by 15 (originally 22) F-35Bs, which will form
10944-510: 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
11096-527: The Society was founded with the word "American" in its name, the membership was international; and the focus is all vertical flight aircraft, including non-helicopter rotorcraft (such as the V-22 Osprey ), jet-borne V/STOL (such as the AV-8 Harrier and F-35 Lightning II ), electric VTOL , and other non-conventional configurations. AV-8 Harrier The McDonnell Douglas (now Boeing ) AV-8B Harrier II
11248-598: The U.S. The two-seaters, the first to be delivered, arrived at Grottaglie in August 1991. They were used for proving flights with the navy's helicopter carriers and on the light aircraft carrier Giuseppe Garibaldi . In early 1994, the initial batch of U.S.-built aircraft arrived at MCAS Cherry Point for pilot conversion training. The first Italian-assembled Harrier was rolled out the following year. In mid-January 1995, Giuseppe Garibaldi set off from Taranto to Somalia with three Harriers on board to maintain stability following
11400-532: The USMC Harrier II as one of several important weapons in the Gulf War . It also served in Operation Enduring Freedom in Afghanistan, the Iraq War and subsequent War in Iraq , along with Operation Odyssey Dawn in Libya in 2011. Italian and Spanish Harrier IIs have taken part in overseas conflicts in conjunction with NATO coalitions. During its service history, the AV-8B has had a high accident rate, related to
11552-439: The USMC has never had any plans to operate those Harriers. On 14 September 2012, a Taliban raid destroyed six AV-8Bs and severely damaged two others while they were parked on the ramp at Camp Bastion in Afghanistan's Helmand Province . All of the aircraft belonged to VMFA-211 . The two damaged AV-8Bs were flown out of Afghanistan in the hours after the attack. The attack was described as "the worst loss of U.S. airpower in
11704-628: The USMC, insisted that the new design be verified with flight testing. McDonnell Douglas modified two AV-8As with new wings, revised intakes, redesigned exhaust nozzles, and other aerodynamic changes; the modified forward fuselage and cockpit found on all subsequent aircraft were not incorporated on these prototypes. Designated YAV-8B, the first converted aircraft flew on 9 November 1978. The aircraft performed three vertical take-offs and hovered for seven minutes at Lambert–St. Louis International Airport . The second aircraft followed on 19 February 1979 but crashed that November because of an engine flameout ;
11856-518: The USN purchased the UK's fleet of 72 retired BAe Harrier IIs (63 single-seat GR.7/9/9As plus 9 twin-seat T.12/12As) and replacement engines to provide spares for the existing USMC Harrier II fleet. Although the March 2012 issue of the magazine AirForces Monthly states that the USMC intended to fly some of the ex-British Harrier IIs, instead of using them just for spare parts, the Naval Air Systems Command (NAVAIR) has since stated that
12008-699: 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
12160-481: The United States. Some of the types listed here are not strictly defined as aircraft carriers by some sources. 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
12312-468: The advancement of the theory and practices of helicopter and other VTOL aircraft technology, and publishes their proceedings. Its AHS Forum is the largest vertical flight technical conference in the world, with over 1200 attendees. Formed in 1943 as the American Helicopter Society, it publishes a general audience vertical flight technology magazine, Vertiflite , as well as one of the only technical publication devoted solely to vertical flight, The Journal of
12464-515: The air wing of Cavour . Spain, already using the AV-8S Matador, became the first international operator of the AV-8B by signing an order for 12 aircraft in March 1983. Designated VA-2 Matador II by the Spanish Navy ( Armada Española ), this variant is known as EAV-8B by McDonnell Douglas. Pilot conversion took place in the U.S. On 6 October 1987, the first three Matador IIs were delivered to Naval Station Rota . The new aircraft were painted in
12616-462: 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
12768-522: The aircraft fundamentally easier to fly. Ed Harper, general manager for the McDonnell Douglas Harrier II development program, summarizes: "The AV-8B looks a lot like the original Harrier and it uses the same operating fundamentals. It just uses them a lot better". A large cathode-ray tube multi-purpose display, taken from the F/A-18, makes up much of the instrument panel in the cockpit. It has
12920-493: The aircraft generally carrying a LITENING pod. Despite the Harrier's high marks, the limited amount of time that each aircraft could remain on station, around 15–20 minutes, led to some calls from within the USMC for the procurement of AC-130 gunships, which could loiter for six hours and had a heavier close air support capability than the AV-8B. AV-8Bs were later used in combination with artillery to provide constant fire support for ground forces during heavy fighting in 2004 around
13072-523: 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,
13224-506: 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
13376-513: 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
13528-516: 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
13680-530: The coast of Pakistan in October 2001. Operating from the unit's ships, four AV-8Bs began attack missions into Afghanistan on 3 November 2001. The 26th MEU and its AV-8Bs joined 15th MEU later that month. In December 2001, two AV-8Bs first deployed to a forward base at Kandahar in Afghanistan. More AV-8Bs were deployed with other USMC units to the region in 2002. The VMA-513 squadron deployed six Night Attack AV-8Bs to Bagram in October 2002. These aircraft each carried
13832-530: 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
13984-449: 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
14136-433: The crew and avionics hardware, McDonnell Douglas elevated the cockpit by 10.5 in (27 cm) and redesigned the canopy. This improved the forward (17° down), side (60°), and rear visibility. The front fuselage is composed of a molded skin with an epoxy-based core sandwiched between two carbon-fiber sheets. To compensate for the changes in the front fuselage, the rear fuselage was extended by 18 in (46 cm), and
14288-530: 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
14440-462: 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
14592-489: The design until the early 2000s, when the project was abandoned. In 2013, the USMC was studying potential enhancements to keep the AV-8B Harrier IIs up to date until its planned retirement, such as a helmet-mounted cueing system. It is also predicted that additional work on the aircraft's radars and sensor systems may take place. The USMC's Harrier II fleet was planned to remain in service until 2030, owing to delays with
14744-417: 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
14896-434: 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
15048-661: The domain of the air force. In early 1989, the law was changed to allow the navy to operate any fixed-wing aircraft with a maximum weight of over 3,300 lb (1,500 kg). Following a lengthy evaluation of the Sea Harrier and AV-8B, an order was placed for two TAV-8Bs in May 1989. Soon, a contract for a further 16 AV-8B Plus aircraft was signed. After the TAV-8Bs and the first three AV-8Bs, all subsequent Italian Navy Harriers were locally assembled by Alenia Aeronautica from kits delivered from
15200-586: The engine went to Rolls-Royce , which had absorbed Bristol Siddeley, with the remaining 25% assigned to Pratt & Whitney . The two companies planned to manufacture 400 Harrier IIs, with the USMC expected to procure 336 aircraft and the RAF to procure 60. Four full-scale development (FSD) aircraft were constructed. The first of these, used mainly for testing performance and handling qualities, made its maiden flight on 5 November 1981. The second and third FSD aircraft, which introduced wing leading-edge root extensions and revised engine intakes, first flew in April
15352-407: The engine's diameter was too large by 2.75 in (70 mm) to fit into the Harrier easily. In December 1973, a joint American and British team completed a project document defining an advanced Harrier powered by the Pegasus 15 engine. The advanced Harrier was intended to replace the original RAF and USMC Harriers, as well as the USMC's A-4 Skyhawk. The aim of the advanced Harrier was to double
15504-580: 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
15656-549: The first Harrier II to be modified for night attacks, leaving the McDonnell Douglas production line in June 1987. Flight tests proved successful and the night attack capability was validated. The first of 66 AV-8B(NA)s was delivered to the USMC in September 1989. An equivalent version of the AV-8B(NA) also served with the RAF under the designation GR7; earlier GR5 aircraft were subsequently upgraded to GR7 standards. In June 1987, as
15808-421: 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
15960-457: 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
16112-404: 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
16264-424: 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
16416-454: 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
16568-604: The following year; the fourth followed in January 1984. The first production AV-8B was delivered to the Marine Attack Training Squadron 203 (VMAT-203) at Marine Corps Air Station Cherry Point on 12 December 1983, and officially handed over one month later. The last of the initial batch of 12 was delivered in January 1985 to the front-line Marine Attack Squadron 331 . These aircraft had F402-RR-404A engines, with 21,450 lb (95.4 kN) of thrust; aircraft from 1990 onwards received upgraded engines. During
16720-412: 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
16872-422: The initial phase of the preparatory air assault of Operation Desert Storm. The AV-8B was first used in the war on the morning of 17 January 1991, when a call for air support from an OV-10 Bronco forward air controller against Iraqi artillery that was shelling Khafji and an adjacent oil refinery, brought the AV-8B into combat. The following day, USMC AV-8Bs attacked Iraqi positions in southern Kuwait. Throughout
17024-526: The initial pilot conversion course, it became apparent that the AV-8B exhibited flight characteristics different from the AV-8A. These differences, as well as the digital cockpit fitted instead of the analog cockpit of the TAV-8A, necessitated additional pilot training. In 1984, funding for eight AV-8Bs was diverted to the development of a two-seat TAV-8B trainer. The first of the 28 TAV-8Bs eventually procured had its maiden flight on 21 October 1986. This aircraft
17176-438: 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
17328-477: The insurgent stronghold of Fallujah . The urban environment there required extreme precision for airstrikes. On 20 March 2011, USMC AV-8Bs were launched from USS Kearsarge in support of Operation Odyssey Dawn , enforcing the UN no-fly zone over Libya. They carried out airstrikes on Sirte on 5 April 2011. Multiple AV-8Bs were involved in the defense of a downed F-15E pilot, attacking approaching Libyans prior to
17480-498: 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
17632-542: The nose, tail, and wingtips to provide control at low airspeeds. The AV-8B is equipped with one centerline fuselage and six wing hardpoints (compared to four wing hardpoints on the original Harrier), along with two fuselage stations for a 25 mm GAU-12 cannon and ammunition pack. These hardpoints give it the ability to carry a total of 9,200 lb (4,200 kg) of weapons, including air-to-air , air-to-surface , and anti-ship missiles , as well as unguided and guided bombs . The aircraft's internal fuel capacity
17784-471: The operational evaluation (OPEVAL), lasting from 31 August 1984 to 30 March 1985, four pilots and a group of maintenance and support personnel tested the aircraft under combat conditions. The aircraft was graded for its ability to meet its mission requirements for navigating, acquiring targets, delivering weapons, and evading and surviving enemy actions, all at the specified range and payload limits. The first phase of OPEVAL, running until 1 February 1985, required
17936-527: 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
18088-570: The percentage of time spent in critical take-off and landing phases. USMC and Italian Navy AV-8Bs are being replaced by the Lockheed Martin F-35B Lightning II , with the former expected to operate its Harriers until 2025. In the late 1960s and early 1970s, the first-generation Harriers entered service with the Royal Air Force (RAF) and USMC but were handicapped in range and payload . In short takeoff and landing configuration,
18240-417: The pilot ejected safely. Flight testing of these modified AV-8s continued into 1979. The results showed greater than expected drag , hampering the aircraft's maximum speed. Further refinements to the aerodynamic profile yielded little improvement. Positive test results in other areas, including payload, range, and V/STOL performance, led to the award of a development contract in 1979. The contract stipulated
18392-473: The pilot's extraction by a MV-22 Osprey . In addition to major conflicts, USMC AV-8Bs have been deployed in support of contingency and humanitarian operations, providing fixed-wing air cover and armed reconnaissance. The aircraft served in Somalia throughout the 1990s, Liberia (1990, 1996, and 2003), Rwanda (1994), Central African Republic (1996), Albania (1997), Zaire (1997), and Sierra Leone (1997). The AV-8B
18544-408: 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,
18696-405: The program received a boost when British Aerospace (BAe) and McDonnell Douglas signed a memorandum of understanding , marking the UK's re-entry into the program. The British government was enticed by the lower cost of acquiring Harriers promised by a large production run, and the fact that the U.S. was shouldering the expense of development. Under the agreement, BAe was relegated to the position of
18848-420: The project later that year. Despite the project's termination, the two companies continued to take different paths toward an enhanced Harrier. Hawker Siddeley focused on a new larger wing that could be retrofitted to existing operational aircraft, while McDonnell Douglas independently pursued a less ambitious, though still expensive, project catering to the needs of the U.S. military. Using knowledge gleaned from
19000-488: The radar, the angle-rate bombing system was removed. The radars used were taken from early F/A-18 aircraft, which had been upgraded with the related APG-73. According to aviation author Lon Nordeen, the changes "had a slight increase in drag and a bit of additional weight, but there really was not much difference in performance between the [–408-powered] Night Attack and radar Harrier II Plus aircraft". The AV-8B underwent standard evaluation to prepare for its USMC service. In
19152-475: The responsibilities of the three countries and establish a Joint Program Office to manage the program. On 30 November 1990, the USN, acting as an agent for the three participating countries, awarded McDonnell Douglas the contract to develop the improved Harrier. The award was followed by an order from the USMC in December 1990 for 30 new aircraft, and 72 rebuilt from older aircraft. Italy ordered 16 Harrier II Plus and two twin-seat TAV-8B aircraft, while Spain signed
19304-595: 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
19456-494: 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
19608-523: 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
19760-625: The start of a successful flight-test program. The first production aircraft made its initial flight on 17 March 1993. Deliveries of new aircraft took place from April 1993 to 1995. At the same time, the plan to remanufacture existing AV-8Bs to the Plus standard proceeded. On 11 March 1994, the Defense Acquisition Board approved the program, which initially involved 70 aircraft, with four converted in fiscal year 1994. The program planned to use new and refurbished components to rebuild aircraft at
19912-470: The taller vertical stabilizer of the Sea Harrier was used. The tail assembly is made up of composites to reduce weight. Perhaps the most thorough redesign was of the wing, the objective being to match the performance of the canceled AV-16 while retaining the Pegasus engine of the AV-8A. Engineers designed a new, one-piece supercritical wing, which improves cruise performance by delaying the rise in drag and increasing lift-to-drag ratio. Made of composites,
20064-508: 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
20216-497: The war, AV-8Bs performed armed reconnaissance and worked in concert with coalition forces to destroy targets. During Operations Desert Shield and Desert Storm, 86 AV-8Bs amassed 3,380 flights and about 4,100 flight hours, with a mission availability rate of over 90%. Five AV-8Bs were lost to enemy surface-to-air missiles , and two USMC pilots were killed. The AV-8B had an attrition rate of 1.5 aircraft for every 1,000 sorties flown. U.S. Army General Norman Schwarzkopf later named
20368-402: 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
20520-460: The wing allows for a 6,700 lb (3,035 kg) increase in payload compared with the first-generation Harriers after a 1,000 ft (300 m) takeoff roll. Because the wing is almost exclusively composite, it is 330 lb (150 kg) lighter than the AV-8A's smaller wing. The Harrier II was the first combat aircraft to extensively employ carbon-fiber composite materials, exploiting their light weight and high strength; they are used in
20672-429: The wing is thicker and has a longer span than that of the AV-8A. Compared to the AV-8A's wing, it has a higher aspect ratio , reduced sweep (from 40° to 37°), and an area increased from 200 sq ft (18.6 m ) to 230 sq ft (21.4 m ). The wing has a high-lift configuration, employing flaps that deploy automatically when maneuvering, and drooped ailerons . Using the leading edge root extensions,
20824-404: The wing would have had folding wingtips . To meet the heavier weight of the aircraft, Rolls-Royce was expected to design a Pegasus engine variant that would have produced 4,000 lbf (18 kN) more thrust than the latest production variant at the time. The Harrier III would have carried weapons such as AIM-120 AMRAAM and AIM-132 ASRAAM missiles. Boeing and BAE Systems continued studying
20976-411: The wings, rudder , flaps, nose, forward fuselage, and tail. Twenty-six percent of the aircraft's structure is made of composites, reducing its weight by 480 lb (217 kg) compared to a conventional metal structure. Most of the first "day attack" AV-8B Harrier IIs were upgraded to Night Attack Harrier or Harrier II Plus standards, with the remainder being withdrawn from service. The AV-8B cockpit
21128-403: The withdrawal of UN forces. The Harriers, flown by five Italian pilots, accumulated more than 100 flight hours and achieved 100% availability during the three-month deployment, performing reconnaissance and other missions. The squadron returned to port on 22 March. In 1999, Italian AV-8Bs were used for the first time in combat missions when they were deployed aboard Giuseppe Garibaldi , which
21280-578: 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 ,
21432-643: 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
21584-455: 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
21736-439: 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
21888-665: Was also studied but not pursued. The UK, through British Aerospace , re-joined the improved Harrier project as a partner in 1981, giving it a significant work-share in the project. Following corporate mergers in the 1990s, Boeing and BAE Systems have jointly supported the program. Approximately 340 aircraft were produced in a 22-year production program that ended in 2003. Typically operated from small aircraft carriers , large amphibious assault ships and simple forward operating bases , AV-8Bs have participated in numerous military and humanitarian operations , proving themselves versatile assets. U.S. Army General Norman Schwarzkopf named
22040-590: Was also used for the early trialing of direct voice input which allows the pilot to use voice commands to issue instructions to the aircraft, using a system developed by Smiths Industries. The main attack avionics system in original aircraft was the nose-mounted Hughes AN/ASB-19 angle-rate bombing system. The system combined a TV imager and laser tracker to provide a highly accurate targeting capability. Defensive equipment include several AN/ALE-39 chaff - flare dispensers, an AN/ALR-67 radar warning receiver , and an AN/ALQ-126 C jammer pod. The trainer version of
22192-550: 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
22344-417: Was delivered to VMAT-203 on 24 July 1987; the TAV-8B was also ordered by Italy and Spain. With export interest from Brazil, Japan, and Italy serving as a source of encouragement to continue development of the Harrier II, McDonnell Douglas commenced work on a night-attack variant in 1985. With the addition of an infrared sensor and cockpit interface enhancements, the 87th production single-seat AV-8B became
22496-583: Was disbanded on 24 October 1986, following the sales of AV-8S Matadors to Thailand. Instead, 9 Escuadrilla was formed on 29 September 1987, to become part of the Alpha Carrier Air Group and operate the EAV-8B. Aircraft carrier An aircraft carrier is a warship that serves as a seagoing airbase , equipped with a full-length flight deck and hangar facilities for supporting, arming, deploying and recovering shipborne aircraft . Typically it
22648-415: 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
22800-650: 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
22952-882: Was participating in Operation Allied Force in Kosovo . Italian pilots conducted more than 60 sorties alongside other NATO aircraft, attacking the Yugoslav army and paramilitary forces and bombing the country's infrastructure with conventional and laser-guided bombs . In 2000, the Italian Navy was looking to acquire 7 additional remanufactured aircraft to equip Giuseppe Garibaldi and a new carrier, Cavour . Existing aircraft, meanwhile, were updated to allow them to carry AIM-120 AMRAAMs and Joint Direct Attack Munition guided bombs. From November 2001 to March 2002, eight AV-8Bs were embarked aboard Giuseppe Garibaldi and were deployed to
23104-468: 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
