142-714: The Bell AH-1 SuperCobra is a twin-engined attack helicopter that was developed on behalf of, and primarily operated by, the United States Marine Corps (USMC). The twin Cobra family, itself part of the larger Huey family , includes the AH-1J SeaCobra , the AH-1T Improved SeaCobra , and the AH-1W SuperCobra . The Super Cobra was derived from the single-engined AH-1 Cobra , which had been developed during

284-516: A 9K38 Igla (SA-18 Grouse) MANPADS; in the published video, the missile severed the tail section from the rest of the helicopter, causing it to spin, fragment in midair and crash, killing the two pilots on board. The Turkish government initially stated that it had descended due to technical failure, though it later became clear that the helicopter had been shot down. Amid the 2016 Turkish coup d'état attempt , Turkish Cobras were alleged to have fired upon several police vehicles. During April 2022, all of

426-536: A foreign object damage hazard with discarded links. A linkless ammunition feed system was developed for the upgraded M61A1 , which subsequently became the standard cannon armament of U.S. fighters. In 1993, General Electric sold its aerospace division, including GE Armament Systems along with the design and production tooling for the M61 and GE's other rotary cannon, to Martin Marietta . After Martin's merger with Lockheed ,

568-659: A 23 mm shell which entered one side of his cockpit and exited the other. When the VPAF MiG flew in front of him after making its pass, Tracy opened fire on it. The gun was installed in the Air Force's A-7D version of the LTV A-7 Corsair II where it replaced the earlier United States Navy A-7's Colt Mk 12 cannon and was adopted by the Navy on the A-7C and A-7E. It was integrated into

710-421: A better use of resources. Despite the opposition, Mil managed to persuade the defence minister's first deputy, Marshal Andrey A. Grechko , to convene an expert panel to look into the matter. While the panel's opinions were mixed, supporters of the project eventually held sway and a request for design proposals for a battlefield support helicopter was issued. The development of gunships and attack helicopters by

852-410: A burst controller is generally used to limit the number of rounds fired at each trigger pull. Bursts of from two or three up to 40 or 50 can be selected. The size of the airframe and available internal space limits the size of the ammunition drum and thus limits the ammunition capacity. When vehicle-mounted, the only limiting factor is the vehicle's safe carry weight, so commensurately larger ammo storage

994-529: A classic single-rotor layout. Its transport capability was removed and it lost its similarity to the Mi-24. Design work on the Mi-28 began under Marat Tishchenko in 1980. In 1981, a design and a mock-up were accepted. The prototype (no. 012) was first flown on 10 November 1982. In this same time frame, Kamov was also attempting to submit its own designs for a new helicopter to the military, which they had designed throughout

1136-730: A common light attack helicopter, other prospective manufacturing participants in the joint initiative included Fokker and Construcciones Aeronáuticas SA . In 1986, the governments of Italy, the Netherlands, Spain and the United Kingdom signed a memorandum of understanding to investigate an improved version of the A129, alternatively called the Joint European Helicopter Tonal or Light Attack Helicopter (LAH). By 1988, feasibility studies for four different options had been conducted for

1278-481: A conventional war ever, as well as the only confirmed helicopter dogfights in history; in particular, Iranian Army Aviation AH-1J SeaCobras engaged with Mi-24 Hind and Mi-8 Hip helicopters of the Iraqi Army Air Corps. The Iranian Cobras also attacked advancing Iraqi divisions in conjunction with fixed-wing F-4 Phantoms armed with Maverick missiles , destroying numerous armoured vehicles and impeded

1420-669: A force of 10 North American F-100 Super Sabres (two of which were assigned weather reconnaissance duties) escorting 48 Vulcan-armed and "bomb-laden" F-105 Thunderchiefs , shooting down two of the latter. The MiG leader and only survivor from the four MiGs, Captain Tran Hanh, reported that U.S. jets had pursued them and that F-105s had shot down three of his aircraft, killing lieutenants Pham Giay, Le Minh Huan and Tran Nguyen Nam. Captain Donald Kilgus, piloting an F-100, received an official probable kill with his four M39 20 mm cannons during

1562-531: A greater emphasis on the attack helicopter's anti-tank capabilities came about. Much of the project's organisational framework was rapidly redeveloped between 1987 and 1989; such as the installation of a Franco-German Helicopter Office to act as a program executive agency in May 1989. Due to the end of the Cold War and subsequent defence budgets decreases in the 1990s, financial pressures led to further questions regarding

1704-496: A hydraulic drive motor through a system of flexible drive shafts. The round is fired by an electric priming system where an electric current from a firing lead passes through the firing pin to the primer as each round is rotated into the firing position. The self-powered version, the GAU-4 (called M130 in Army service), is gas-operated , tapping gun gas from three of the six barrels to operate

1846-456: A major tool against tank warfare, and most attack helicopters became more and more optimized for the antitank mission. Amid the opening months of the Korean War era, during August 1950, a joint US Navy and Marine Corps test used a newly acquired Bell HTL-4 helicopter to test if a bazooka could be fired from a helicopter in flight. One of the larger 3.5 inch (90mm calibre) models of the bazooka

1988-556: A more ambitious helicopter design. In 1978, Agusta formally began the design process on what would become the Agusta A129 Mangusta . On 11 September 1983, the first of five A129 prototypes made the type's maiden flight ; the fifth prototype would first fly in March 1986. The Italian Army placed an order for 60 A129s. The A129 was the first European attack helicopter; as such it has several original aspects to its design, such as being

2130-505: A much higher volume of fire. While captured German designs (principally the Mauser MG 213C ) showed the potential of the single-barrel revolver cannon , the practical rate of fire of such a design was still limited by ammunition feed and barrel wear concerns. The Army wanted something better, combining an extremely high rate of fire with exceptional reliability. In 1947, the Air Force became

2272-605: A new experimental composite four-blade main rotor system. The new configuration offered better performance, reduced noise, and improved battle damage tolerance. Lacking a USMC contract, Bell developed this new design into the AH-1Z with its own funds. By 1996, the Marines were again prevented from ordering the AH-64. Developing a marine version of the Apache would have been expensive and it was likely that

2414-595: A new model, the AH-1T, that was provisioned with a lengthened tailboom and fuselage as well as the upgraded transmission and engines from the Model 309. Bell designed the AH-1T to be more reliable and easier to maintain in the field. The version was given full TOW missile capability with targeting system and other sensors. An advanced version, known as the AH-1T+, that was equipped with more powerful T700-GE-700 engines and advanced avionics,

2556-482: A production contract for 110 AH-1G Cobras. The Cobra had a tandem cockpit seating arrangement (vs UH-1 side-by-side) to make the aircraft a smaller frontal target, increased armor protection, and greater speed. In 1967, the first AH-1Gs were deployed to Vietnam, around the same time that the Cheyenne successfully completed its first flight and initial flight evaluations. And while the Cheyenne program suffered setbacks over

2698-627: A purpose-built attack helicopter with more speed and firepower than current armed helicopters was required in the face of increasingly intense ground fire (often using heavy machine guns and anti-tank rockets) from Viet Cong and NVA troops. Based on this realization, and with the growing involvement in Vietnam, the U.S. Army developed the requirements for a dedicated attack helicopter, the Advanced Aerial Fire Support System (AAFSS). The aircraft design selected for this program in 1965,

2840-529: A separate branch of the military. The new Air Force made a request for a new aircraft gun. A lesson of World War II air combat was that German, Italian, and Japanese fighters could attack American aircraft from long range with their cannon main armament. American fighters with .50 caliber (12.7 mm) main armament, such as the P-51 and P-47 , had to be close to enemy aircraft in order to hit and damage them. The 20 mm (0.79 in) Hispano cannon carried by

2982-476: A set of small wings positioned to the top rear of the passenger cabin, capable of holding up to six missiles or rocket pods, along with a twin-barrel GSh-23L cannon fixed to the landing skid. These designs were proposed by Mil to the Soviet armed forces , and while he had the support of a number of strategists, he was opposed by several more senior members of the armed forces who believed that conventional weapons were

3124-645: A single AH-1T to Iranian anti-aircraft fire. USMC Cobras from Saipan flew "top cover" during an evacuation of U.S. and other foreign citizens from Liberia in 1990. During the Gulf War , 78 Marine SuperCobras were deployed, flying a total of 1,273 sorties in Iraq. While no combat losses were reportedly incurred, three AH-1s were lost to accidents either during and after the combat operations. The AH-1W units were credited with destroying 97 tanks, 104 armored personnel carriers and vehicles, and two anti-aircraft artillery sites during

3266-455: A six-barrel weapon capable of firing 7,200 rounds per minute (rpm). Although European designers were moving towards heavier 30 mm (1.181 in) weapons for better hitting power, the U.S. initially concentrated on a powerful 0.60-inch (15 mm) cartridge designed for a pre-war anti-tank rifle, expecting that the cartridge's high muzzle velocity would be beneficial for improving hit ratios on high-speed targets. The first GE prototypes of

3408-526: A solid reputation as an attack helicopter. In June 1972 the USMC began deploying AH-1J SeaCobra Attack Helicopters for combat operations in South Vietnam. During the late 1970s, the U.S. Army saw the need of more sophistication within the attack helicopter corps, allowing them to operate in all weather conditions. Although AH-1Gs served well, they proved vulnerable even in a mid-intensity environment. With that

3550-486: A suitable aircraft. The Atlas XH-1 Alpha was the first prototype to emerge from the program. It was developed from an Aérospatiale Alouette III airframe, retaining that helicopter's engine and dynamic components, but replacing the original cockpit with a stepped tandem one, adding a 20 mm cannon on the nose and converting the undercarriage to tail-dragger configuration. The XH-1 first flew on 3 February 1985. The results were ultimately good enough to convince Atlas and

3692-640: A total of 3 prototypes had completed over 400 hours of test flights by this time. By 2004, 3 more prototypes were built, for a total of 6, and a second stage of test flights were concluded on December 15, 2004. In one of the test flights the future commander-in-chief of the People's Liberation Army Ground Force Air Force (PLAGAF), Song Xiangsheng ( 宋湘生 ), was on board the prototype. A third stage of intensive test flights followed, taking place during both day and night. By January 2006 weaponry and sensor tests, including firing of live ammunition, had taken place. The helicopter

3834-649: A total of two AH-1Ts were shot down and three crew members killed. That same year, Marine AH-1s were also deployed off the coast of Beirut , Lebanon , amid the Lebanese civil war in support of the Multinational Peacekeeping Force. In this theatre, the AH-1s were typically armed with Sidewinder missiles and guns, which were intended to be used as an emergency air defense measure to counter the threat of light civil aircraft being piloted by suicide bombers . During

3976-463: A unique low-altitude, low-speed capability for close air support. Other purpose-built helicopters were developed for special operations missions, including the MH-6 for extremely close support. During the early 1960s, Soviet engineers started experimenting with various designs aimed at producing an aerial vehicle that could provide battlefield mobility for infantry and provide fire support to army forces on

4118-569: A window from four miles [6.4 km] away at night." However, serious logistical problems limited operations, Apaches in the Iraqi theater flew only one-fifth of planned flight-hours. The "deep attack" role of independently operating attack helicopters came into question after a failed mission, during the 2003 Gulf War attack on the Karbala Gap . A second mission in the same area, four days later, but coordinated with artillery and fixed-wing aircraft,

4260-757: A wingtip station. During October 2020, the last AH-1Ws were phased out of service with the Marine Corps in favor of the AH-1Z. During the closing months of the United States' involvement in the Vietnam War , the Marine Corps embarked the AH-1J SeaCobra assigned to HMA-369 (now HMLA-369) aboard Denver , Cleveland , and later Dubuque , for sea-based interdiction of the Ho Chi Minh Trail in North Vietnam in

4402-561: Is a semi-armor-piercing high-explosive incendiary (SAPHEI) round, providing improvements in range, accuracy, and power over the preceding M56A3 HEI round. The PGU-28/B is a "low-drag" round designed to reduce in-flight drag and deceleration, and has a slightly increased muzzle velocity of 1,050 metres per second (3,450 ft/s). However, the PGU-28/B has not been without problems. A 2000 USAF safety report noted 24 premature detonation mishaps (causing serious damage in many cases) in 12 years with

4544-809: Is an armed helicopter with the primary role of an attack aircraft , with the offensive capability of engaging ground targets such as enemy infantry , military vehicles and fortifications . Due to their heavy armament they are sometimes called helicopter gunships . Attack helicopters can use weapons including autocannons , machine guns , rockets , and anti-tank missiles such as the AGM-114 Hellfire . Some attack helicopters are also capable of carrying air-to-air missiles , though mostly for purposes of self-defense against other helicopters and low-flying light combat aircraft . A modern attack helicopter has two primary roles: first, to provide direct and accurate close air support for ground troops; and second,

4686-452: Is available. Until the late 1980s, the M61 primarily used the M50 series of ammunition in various types, typically firing a 99-gram (3.5 oz) projectile at a muzzle velocity of about 1,030 metres per second (3,380 ft/s). A variety of armor-piercing incendiary (API), high-explosive incendiary (HEI), and training rounds are available. A new PGU-28/B round was developed in the mid-1980s. It

4828-512: Is in excess of 10,000 rounds, making it an extremely reliable weapon. The success of the Vulcan Project and its progeny, the very-high-speed Gatling gun, has led to guns of the same configuration being referred to as "Vulcan cannons" , which can sometimes confuse nomenclature on the subject. Most aircraft versions of the M61 are hydraulically driven and electrically primed. The gun rotor, barrel assembly and ammunition feed system are rotated by

4970-417: Is supplied with sufficient ammunition for a full minute of firing, due to its weight (at 6,000 rpm, the projectiles alone would represent a mass of about 600 kg (1,300 lb) for one minute of firing; and by including the brass shell, filling and primer the weight is slightly double that at 1,225 kg (2,701 lb)). In order to avoid using the 600 to 1,000 rounds carried by aircraft all at once,

5112-510: Is typically 6,000 rounds per minute, although some versions (such as that of the AMX and the F-106 Delta Dart ) are limited to a lower rate, and others ( A-7 Corsair , F-15 Eagle ) have a selectable rate of fire of either 4,000 or 6,000 rounds per minute. The M61A2's lighter barrels allow a somewhat higher rate of fire, up to 6,600 rounds per minute. Practically no powered rotary cannon

5254-476: The 2003 invasion of Iraq . During October 2020, the USMC withdrew the last of its AH-1Ws in favor of exclusively operating the AH-1Z. The AH-1 Cobra was developed in the mid-1960s as an interim gunship for the U.S. Army for use during the Vietnam War . The Cobra shared the proven transmission, rotor system, and the Lycoming T53 turboshaft engine of the prolific UH-1 "Huey" utility helicopter. By June 1967,

5396-552: The Advanced Attack Helicopter (AAH) program started, aiming for a more durable, more advanced, longer range, stronger close air support helicopter, capable of destroying armored formations. It would be capable of carrying the new AGM-114 Hellfire and night fighting capabilities. From this program the Hughes YAH-64 came out as the winner. The prototype YAH-64 was first flown on 30 September 1975. The U.S. Army selected

5538-516: The F-22 Raptor , designated M61A2, is mechanically the same as the M61A1, but with thinner barrels to reduce overall weight to 92 kilograms (202 lb). The rotor and housing have also been modified to remove any piece of metal not absolutely needed for operation and replaces some metal components with lighter-weight materials. The F/A-18E/F Super Hornet also uses this version. The Vulcan's rate of fire

5680-594: The Iran–Iraq War —which saw the most intensive use of helicopters in any conventional war. Iranian AH-1Js (particularly the TOW-capable ones) were "exceptionally effective" in anti-armor warfare, inflicting heavy losses on Iraqi armored and vehicle formations. In operations over the barren terrain in Khuzestan and later in southern Iraq, beside the standard tactics, Iranian pilots developed special, effective tactics, often in

5822-664: The Kargil War in 1999, the Indian Air Force and the Indian Army found that there was a need for helicopters that can operate at such high-altitude conditions with ease. Limitations in terms of both high payloads and maneuverability of the existing Mi-35 fleet reportedly contributed to India developing indigenous rotorcraft, such as the HAL Prachand and HAL Rudra , to perform multi-role high-altitude combat operations. The HAL Rudra

5964-544: The MBB Bo 105 and MD 500 helicopters. The requirement resulted in an order for 42 AH-1W SuperCobras being placed during 1992. Deliveries of this batch ran from 1993 to 1997. During 1997, it was announced that an additional 21 AH-1Ws had been ordered. The Ministry of National Defense assigned the helicopters to the ROC Army Aviation Training Centre and a pair of Army Aviation attack helicopter brigades. During

6106-523: The P-38 and P-61 , while formidable against propeller-driven planes, had a relatively low rate of fire in the age of jets, while other cannons were notoriously unreliable. In response to this requirement, the Armament Division of General Electric resurrected an old idea: the multi-barrel Gatling gun . The original Gatling gun had fallen out of favor because of the need for an external power source to rotate

6248-549: The SUU-16/A (also designated M12 by the US Army) and improved SUU-23/A (US Army M25), were developed in the 1960s, often used on gunless versions of the F-4. The SUU-16/A uses the electric M61A1 with a ram-air turbine to power the motor. This proved to cause serious aerodynamic drag at higher speeds, while speeds under 640 kilometres per hour (400 mph) did not provide enough airflow for

6390-452: The Vietnam War , to this day the pair of most produced helicopter designs in aviation history. These helicopters proved to be moderately successful in these configurations, but due to a lack of armor protection and speed, they were ultimately ineffective platforms for mounting weapons in higher-threat ground combat environments. Since the 1960s, various countries around the world started to design and develop various types of helicopters with

6532-706: The Z-10 ( Chinese : 直-10 ; lit. 'helicopter-10'). The 602nd Research Institute was assigned as the chief designer, while Harbin Aircraft Manufacturing Corporation (HAMC) of China Aviation Industry Corporation II (AVIC II) was assigned as the primary manufacturer. Nearly four dozen other establishments participated in the program. According to Chinese sources, the initial test flights were concluded on December 17, 2003, whereas according to other sources they were completed nine months earlier in March 2003. According to Jane's Information Group ,

6674-406: The anti-tank role to destroy grouped enemy armored vehicles . Attack helicopters are also used as protective escort for transport helicopters , or to supplement lighter helicopters in the armed reconnaissance roles. In combat, an attack helicopter is projected to destroy targets worth around 17 times its own production cost before being destroyed. Low-speed, fixed wing Allied aircraft like

6816-510: The 0.60-inch (15 mm) caliber T45 were ground-fired in 1949; it achieved 2,500 rpm, which was increased to 4,000 rpm by 1950. By the early 1950s, the USAF decided that high velocity alone might not be sufficient to ensure target destruction and tested 20 and 27 mm (0.787 and 1.06 in) alternatives based on the 0.60-inch (15 mm) caliber cartridge. These variants of the T45 were known as

6958-481: The 100-hour ground campaign. USMC Cobras were also used in various other operations throughout the 1990s. The type provided support for the U.S. humanitarian intervention in Somalia, Operation Restore Hope , during 1992–1993. They were also employed during the U.S. invasion of Haiti during 1994. USMC Cobras were used in U.S. military interventions in the former Yugoslavia in the 1990s; specifically, two AH-1Ws assisted in

7100-556: The 2010s, Taiwan began supplementing its SuperCobras with 30 newly purchased AH-64Es. Into the 2020s, Taiwan continues to operate its SuperCobras; during January 2021, a NT$ 339.24 million (US$ 11.91 million) contract with the US was signed for the provision of technical support and spare parts the AH-1W fleet through to September 2027. During the early 1990s, Turkey bought ten AH-1W SuperCobras; these were supplemented by 32 ex-US Army AH-1 Cobras. The sale

7242-511: The 2011 military intervention was to protect civilians in accordance with UN Security Council Resolution 1973 . Within days of the Apaches deployment, it had completed a variety of tasks such as destroying tanks, checkpoints held by pro-Gaddafi forces and vehicles carrying ammunitions loyal to Muammar Gaddafi . Apache operations over Libya have been heavily influenced and supported by NATO reconnaissance flights and intelligence missions; information

7384-524: The 21st century. Changes in the military situation after the Cold War made specialized anti-tank helicopters less useful. The advantages of the Mi-28N, like all-weather action ability, lower cost, and similarity to the Mi-24, have become more important. In 2003, the head of Russian Air Force stated that the Mi-28N and Ka-50 attack helicopters will become the standard Russian attack helicopter. The first serial Mi-28N

7526-479: The 6-ton class China Medium Helicopter (CHM) program in 1994. The program was promoted as a civilian project, and was able to secure significant Western technical assistance, such as from Eurocopter (rotor installation design consultancy), Pratt & Whitney Canada (PT6C turboshaft engine) and Agusta Westland (transmission). The Chinese concentrated on areas where it could not obtain foreign help. The 602nd Research Institute's called its proposed armed helicopter design

7668-466: The A129 was derived from the A109 and incorporated to an entirely new forward section. The A129's fuselage is highly angular and armoured for ballistic protection; the composite rotor blades are also able to withstand hits from 23mm cannon fire. The two man crew, comprising a pilot and gunner, sit in a conventional tandem cockpit. During the 1980s, Agusta sought to partner with Westland Helicopters to develop

7810-521: The AH-1Js were lost during the conflict to combat, accidents, and simple wear and tear. Ali Akbar Shiroodi and Ahmad Keshvari were two distinguished Iranian Cobra pilots during Iran-Iraq War and are considered wartime heroes in Iran. During 1988, two Soviet MiG-23s shot down a pair of Iranian AH-1Js that had strayed into western Afghan airspace. Into the twenty-first century, Iranian AH-1Js remain in service with

7952-515: The AH-1W SuperCobra commenced, eventually totaling 179 new-built helicopters along with the upgrading of 43 existing AH-1Ts. During the late 1990s, Bell was negotiating to acquire the Romanian state-managed helicopter manufacturer IAR Brașov with the intention of establishing an overseas production line for the AH-1W for multiple export customers. In May 1997, the company signed an agreement with

8094-589: The Block 1F standard by 2011. The upgrade involves improved targeting systems and other avionics which enable the helicopter to use guided missiles for the first time. The Mokopa ATGM was qualified as part of the upgrade process. Gearbox components were improved and cooling problems with the F2 20 mm cannon were also addressed. On 1 April 2011, the South African Air Force received the first five of eleven (one of

8236-584: The Democratic Republic of the Congo . This was the first combat deployment for the helicopter. Three helicopters from 16 Squadron SAAF were deployed to the region and since November 2013 it was involved in heavy fighting alongside the United Nations Force Intervention Brigade , against rebels operating in North Kivu , in particular the M23 militia , which consisted of hardened former government troops equipped with relatively heavy weaponry such as main battle tanks and anti-aircraft weaponry. During its first ever combat mission it proved to be instrumental in routing

8378-512: The French Army took place on 18 March 2005; the first official Tiger delivery to the Germany followed on 6 April 2005. Germany reduced its order to 57 in March 2013. In 2008 OCCAR estimated the project cost at € 7,300,000,000. France's FY2012 budget put their share of the project at €6.3bn (~US$ 8.5bn), implying a programme cost of €14.5bn (~US$ 19.5bn) to the three main partners. At FY2012 prices, their 40 HAP cost €27m/unit (~US$ 36m) and their 40 HAD €35.6m/unit (~US$ 48m), including development costs

8520-406: The French Tigers cost €78.8m (~US$ 106m) each. The Rooivalk project began in early 1984 under the auspices of the Atlas Aircraft Corporation , a predecessor of Denel Aviation . Faced with the increasingly conventional nature of the South African Border War , the South African Defence Force recognised the need for a dedicated attack helicopter and accordingly set along the process of developing

8662-480: The Iran–Iraq War. The results of these engagements are disputed. One document cited that Iranian AH-1Js took on Iraqi Mi-8 and Mi-24 helicopters. Sources report that the Iranian AH-1 pilots achieved a 10:1 kill ratio over the Iraqi helicopter pilots during these engagements (1:5). Additionally, one source states that ten Iranian AH-1Js were lost in the war, compared to six Iraqi Mi-24s lost. The skirmishes are described as fairly evenly matched in another source. The Mi-24

8804-734: The Iraqi advance, albeit not completely halting it. The 1990s could be seen as the coming-of-age for the U.S. attack helicopter. The AH-64 Apache was used extensively during Operation Desert Storm with great success, being used to fire the first shots of the conflict, destroying Iraqi early warning radar and surface-to-air missile (SAM) sites with their Hellfire missiles . They were later used successfully in both of their operational roles, to direct attack against enemy armor and as aerial artillery in support of ground troops; both Hellfire missile and cannon attacks by Apaches destroyed numerous enemy tanks and armored cars. General Carl Stiner claimed that: "You could fire that Hellfire missile through

By the 2020s, there was an increasing expectation that, amid a combination of factors such as accumulated fatigue , increasingly outdated capabilities, and a shortage of spare components, Iran will probably seek to replace its AH-1Js before too long, possibly with Russian-sourced Mi-24s. During 1984, Taiwan announced its requirement for attack helicopters; it subsequently evaluated

9088-444: The Italian/Brazilian AMX International AMX (on Italian aircraft only), and the F-22 Raptor . It was fitted in a side-firing installation on the Fairchild AC-119 and some marks of the Lockheed AC-130 gunships , and was used in the tail turrets of both the Convair B-58 Hustler and Boeing B-52H Stratofortress bombers. Japan's Mitsubishi F-1 carried one internally mounted JM61A1 Vulcan with 750 rounds. Two gun pod versions,

9230-493: The L-4 Grasshopper, begun to be used in a light anti-armor role by a few U.S. Army artillery spotter units over France; these aircraft were field-outfitted with either two or four bazooka rocket launchers attached to the lift struts , against German armored fighting vehicles. During the summer of 1944, U.S. Army Major Charles Carpenter managed to successfully take on an anti-armor role with his rocket-armed Piper L-4. His L-4, bearing US Army serial number 43-30426 and named Rosie

9372-410: The LAH, these would have between 80 per cent and 20 per cent growth over the initial A129; both single-engine and twin-engine configurations were examined using various new powerplants, as well as a new rotor system, retractable landing gear, improved sensors and more powerful armament. However, the LAH project collapsed in 1990 following Britain and the Netherlands independently deciding to withdraw from

9514-404: The M61 gun internally. The Vulcan was later fitted into the weapons bay of some Convair F-106 Delta Dart and General Dynamics F-111 Aardvark models. It was also adopted as standard in the "teen"-series air superiority fighters: the Grumman F-14 Tomcat , the McDonnell Douglas F-15 Eagle , General Dynamics F-16 Fighting Falcon , and McDonnell Douglas F/A-18 Hornet . Other aircraft include

9656-522: The Marine Corps would be its only customer. Instead, the service signed a contract for the upgrading of AH-1Ws into AH-1Zs. The Bell AH-1Z Viper retained much of the AH-1W's design, but also features several major changes. The AH-1Z's two redesigned wing stubs are longer with each adding a wingtip station for a missile such as the AIM-9 Sidewinder . Each wing has two other stations for 70 mm (2.75 in) Hydra rocket pods, or AGM-114 Hellfire quad missile launcher. The Longbow radar can be mounted on

9798-417: The Rocketer , armed with six bazookas, had notable success in an engagement during the Battle of Arracourt on September 20, 1944, employing top attack tactics in knocking out at least four German armored vehicles, as a pioneering example of taking on heavy enemy armor from a slow-flying aircraft. The Germans were also engaged in such ad hoc low-speed light aircraft platforms for ground attack very late in

9940-411: The Romanian State Ownership Fund to buy the government's 70 percent stake in IAR Brașov. However, during November 1999, following protracted negotiations, Bell announced that it had abandoned its acquisition efforts, and thus the overseas production initiative, after the Romanian government had allegedly ceased responding to its proposals. The AH-1T+ demonstrator and AH-1W prototype were later tested with

10082-399: The SAAF that the concept was feasible, opening the door for the development of the Rooivalk. During the Rooivalk's development, it was decided to base the aircraft on the dynamic components of the Aérospatiale Super Puma , a larger and more powerful helicopter. These components were already used on the Atlas Oryx , a local upgrade and modification of the Aérospatiale Puma . Unfortunately,

10224-618: The SAPHEI round, compared to only two such mishaps in the entire recorded history of the M56 round. The report estimated that the PGU-28/B had a potential failure rate 80 times higher than USAF standards permit. Due to safety issues, it was limited to emergency wartime use in 2000. The main types of combat rounds and their main characteristics are listed in the table: The Vulcan was first used in aerial combat on 4 April 1965, when four North Vietnamese Vietnam People's Air Force (VPAF) MiG-17s ) attacked

10366-772: The Soviet Polikarpov Po-2 training and utility biplane had been used as early as 1942 to provide night harassment attack capability against the Wehrmacht Heer on the Eastern Front , most effectively in the Battle of the Caucasus as exemplified by the Night Witches all-female Soviet air unit. Following Operation Overlord in 1944, the military version of the similarly slow-flying Piper J-3 Cub high-wing civilian monoplane,

10508-654: The T171 and T150 respectively and were first tested in 1952. Eventually, the standard 20×102 mm cartridge was determined to have the desired balance of projectile/explosive mass and muzzle velocity, resulting in an optimum balance of range, accuracy and kinetic energy on target. The development of the Lockheed F-104 Starfighter revealed that the T171 Vulcan (later redesignated M61 ) suffered problems with its linked ammunition , being prone to misfeed and presenting

10650-1102: The Turkish Army's remaining AH-1Ws were transferred to the Turkish Navy; they are the first type of attack helicopter to be operated by the service. Being already appropriately suited to maritime operations, the AH-1Ws are to be used on board the TCG Anadolu amphibious assault ship ; as such, the type has been speculated to have displaced a planned navalised version of the indigenously built TAI/AgustaWestland T129 ATAK attack helicopter.

10792-644: The UH-1B. The three highest-ranked aircraft, the Sikorsky S-61 , Kaman H-2 "Tomahawk" , and the Bell AH-1 Cobra , were selected to compete in flight trials conducted by the Army's Aviation Test Activity. Upon completion of the flight evaluations, the Test Activity recommended Bell's Huey Cobra to be an interim armed helicopter until the Cheyenne was fielded. On 13 April 1966, the U.S. Army awarded Bell Helicopter Company

10934-655: The US Army during the Vietnam War convinced the Soviets of the advantages of armed helicopter ground support doctrine, which had a positive influence on moving forward with the development of the Mil Mi-24 . After several mock-ups were produced, a directive was issued on 6 May 1968 to proceed with development of a twin-engine design of the helicopter. Work proceeded under Mil until his death in 1970. Detailed design work began in August 1968 under

11076-555: The United States. This model featured improvements such as the uprated P&WC T400-WV-402 engine and a strengthened drivetrain. Furthermore, recoil damping gear was fitted to the 20 mm M197 gun turret, while the gunner was provided with a stabilized sight along with a stabilized seat. Of the AH-1Js operated by the Imperial Iranian Army Aviation , 62 were capable of using the TOW missile . Iranian AH-1Js participated in

11218-618: The World War II-era Sikorsky R-4, could be armed with weapons in order to provide them with limited combat capability. Early examples include armed Sikorsky H-34s in service with the US Air Force and armed Mil Mi-4 in service with the Soviet Air Forces . This "experimental" trend towards the development of dedicated attack helicopters continued into the 1960s with the deployment of armed Bell UH-1s and Mil Mi-8s during

11360-670: The YAH-64 over the Bell YAH-63 in 1976, and later approved full production in 1982. After purchasing Hughes Helicopters in 1984, McDonnell Douglas continued and turned it into the AH-64 Apache production and development. The helicopter was introduced to U.S. Army service in April 1986. Today, the US attack helicopter has been further refined, and the AH-64D Apache Longbow demonstrates many of

11502-579: The advanced technologies being considered for deployment on future gunships. The US Marine Corps also continued to employ attack helicopters in the direct fire support role, in the form of the AH-1 Super Cobra . While helicopters were effective tank-killers in the Middle East, attack helicopters are being seen more in a multipurpose role. Tactics, such as tank plinking , showed that fixed-wing aircraft could be effective against tanks, but helicopters retained

11644-429: The barrel assembly, but the new generation of turbojet-powered fighters offered sufficient electric power to operate the gun, and electric operation was more reliable than gas-operated reloading . With multiple barrels, the rate of fire per barrel could be lower than a single-barrel revolver cannon while providing a greater overall rate of fire. The idea of powering a Gatling gun from an external electric power source

11786-529: The codename Yellow 24. A full-scale mock-up of the design was reviewed and approved in February 1969. Flight tests with a prototype began on 15 September 1969 with a tethered hover, and four days later the first free flight was conducted. A second prototype was built, followed by a test batch of ten helicopters. A number of other design changes were made until the production version Mi-24A entered production in 1970, obtaining its initial operating capability in 1971 and

11928-508: The complete weapon. Most aircraft installations are double-ended, because the ejection of empty cartridges can cause a foreign-object damage hazard for jet engines and because the retention of spent cases assists in maintaining the center of gravity of the aircraft. The first aircraft to carry the M61A1 was the C model of the F-104 , starting in 1959. A lighter version of the Vulcan developed for use on

12070-548: The development of the Rooivalk continued until after the conclusion of the South African Border War and defence budgets were slashed due to parliamentary changes to the requirements of the national air force. This resulted in an extensive development and production period beginning in 1990 until 2007, during which 12 aircraft were produced for use by the South African Air Force . These aircraft were subsequently upgraded to

12212-667: The early and mid 1980s. In 1984, the Mi-28 completed the first stage of state trials, but in October 1984 the Soviet Air Force chose the more advanced Kamov Ka-50 as the new anti-tank helicopter. The Mi-28 development was continued, but given lower priority. In December 1987 Mi-28 production in Rosvertol in Rostov-on-Don was approved. After several prototypes were built, production ceased in 1993 with additional development continuing into

12354-450: The engagement; however no other US pilot reported destroying any MiGs during the battle, leaving open the possibility that at least two of the MiG-17s may have been downed by their own anti-aircraft fire. The first confirmed Vulcan gun kill occurred on 29 June 1966 when Major Fred Tracy, flying his F-105 with the 421st TFS, fired 200 rounds of 20 mm into a MiG-17 that had just fired

12496-534: The extensively redesigned and modernised Bell AH-1Z Viper during the 1990s and 2000s. The Sea Cobra was involved in multiple major operations during the latter half of the twentieth century, such as during the United States invasion of Grenada in 1983. During the Iran–Iraq War of the 1980s, Iranian Sea Cobras were intensely used, proving itself to be capable in both anti-armor and anti-aircraft warfare. Turkey , who operated numerous Cobras and Super Cobras, used

12638-477: The first AH-1G HueyCobras had been delivered. Between 1967 and 1973, Bell manufactured 1,116 AH-1Gs for the U.S. Army; these Cobras chalked up in excess of one million operational hours in the Vietnam theatre. The U.S. Marine Corps became particularly interested in the AH-1G Cobra, but expressed its preference for a twin-engined configuration that would provide improved safety in over-water operations. Furthermore,

12780-417: The first helicopter to make use of a fully computerised integrated management system to reduce crew workload. It was decided that much of the helicopter's functionality was to be automated; as such, parts of the flight and armament systems are monitored and directly controlled by onboard computers. The A129 shares considerable design similarities to Agusta's earlier A109 utility helicopter; the rear section of

12922-482: The following decade, in response to the denial of funding to procure the Boeing AH-64 Apache attack helicopter, the USMC opted to procure a more capable variant of the AH-1T; equipped with revised fire control systems compatible with new munitions, such as the AGM-114 Hellfire anti-tank missile, the new model, designated AH-1W, commenced delivery in 1986. Seeking to further develop the type, Bell opted to develop

13064-706: The future Z-10's requirements. Research also decided that anti-tank missiles like the BGM-71 TOW were inadequate, and favored an analogue to the AGM-114 Hellfire. The Gulf War highlighted the urgent need for attack helicopters, and revalidated the assessment that a purpose-built design was needed. (At the time, the Chinese military depended on armed utility helicopters such as the Changhe Z-11 and Harbin Z-9.) Also, it demonstrated that

13206-537: The ground. The first of these concepts was a mock-up unveiled in 1966 in the experimental shop of the Ministry of Aircraft's factory number 329, where Mikhail Leont'yevich Mil was head designer. The mock-up, which was designated V-24, was based on another project, the V-22 utility helicopter , which itself never entered production. The V-24 had an infantry transport compartment that could hold eight troops sitting back to back, and

13348-452: The gun gas-driven mechanism. The self-powered Vulcan weighs about 4.5 kilograms (10 lb) more than its electric counterpart, but requires no external power source to operate, except for an electric inertia starter to initiate gun rotation, allowing the first rounds to be chambered and fired. The initial M61 used linked ammunition, but the ejection of spent links created considerable (and ultimately insuperable) problems. The original weapon

13490-493: The increasing numbers of post-war military helicopter designs. The only American helicopter in use during the war years, the Sikorsky R-4 , was only being used for rescue and were still very much experimental in nature. In the early 1950s, various countries around the world started to make increased use of helicopters in their operations in transport and liaison roles. Later on it was realised that these helicopters, successors to

13632-493: The maximum rate of fire. The subsequent SUU-23/A uses the GAU-4/A self-powered Vulcan, with an electric inertia starter to bring it up to speed. Both pods ejected empty cases and unfired rounds rather than retaining them. Both pods contained 1,200 rounds of ammunition, with a loaded weight of 733 and 780 kilograms (1,615 and 1,720 lb) respectively. During service in the Vietnam War , the pods proved to be relatively inaccurate:

13774-454: The mid-1960s as an interim gunship for the U.S. Army. The USMC had quickly taken an interest in the type, but sought a twin-engined arrangement for greater operational safety at sea, along with more capable armaments. While initially opposed by the Department of Defense , who were keen to promote commonality across the services, in May 1968, an order for an initial 49 twin-engine AH-1J SeaCobras

13916-537: The mid-1980s, the AH-1W variant entered service with the USMC. Between, 1986 to 1999, the service took delivery of 179 Super Cobras. In the late 1980s, in response to the Tanker War of the wider Iran–Iraq War , USMC Cobras were dispatched for Operation Earnest Will in the Persian Gulf to escort shipping and deter attacks upon them. It was during these missions that Cobras sank three Iranian patrol boats while losing

14058-509: The military customers the Tiger was being developed for. Both France and Germany reorganised the programme. Thomson-CSF also took over the majority of the Tiger's electronic development work, such as the visual systems and sensors. Despite the early development problems and the political uncertainty between 1984 and 1986, the program was formally relaunched in November 1987; it was at this point that

14200-524: The military; these were no longer adequate in the attack role, and suitable only as scouts. Following this, China evaluated the Agusta A129 Mangusta, and in 1988 secured an agreement with the US to purchase AH-1 Cobras and a license to produce BGM-71 TOW missiles; the latter was cancelled following the Tiananmen Square protests of 1989 and the resulting arms embargo. The color revolutions prevented

14342-560: The necessity for the entire program. In 1992, Aérospatiale and MBB, among other companies, merged to form the Eurocopter Group; this led to considerable consolidation of the aerospace industry and the Tiger project itself. A major agreement was struck in December 1996 between France and Germany that cemented the Tiger's prospects and committed the development of supporting elements, such as a series of new generation missile designs for use by

14484-489: The new attack helicopter would need to be able to defend itself against other helicopters and aircraft. The military perceived that once the new attack helicopter entered service, the existing helicopters would be used as scouts. The Armed Helicopter Developmental Work Team ( 武装直升机开发工作小组 ) was formed to develop a new medium helicopter design, as opposed to basing the new design on the light helicopters then in service. The 602nd and 608th Research Institutes started development of

14626-405: The new combat helicopter. On 18 June 1999, both Germany and France publicly placed orders for an initial batch of 160 Tiger helicopters, 80 for each nation, valued at €3.3 billion. On 22 March 2002, the first production Tiger was rolled out in a large ceremony held at Eurocopter's Donauworth factory; although production models began initial acceptance trials in 2003, the first official delivery to

14768-467: The newer F-4E Phantom II variants. The F-4 was originally designed without a cannon as it was believed that missiles had made guns obsolete. Combat experience in Vietnam showed that a gun could be more effective than guided missiles in many combat situations and that an externally carried gun pod was less effective than an internal gun; the first generation of gun pods such as the SUU-16 were not oriented with

14910-468: The next few years due to technical problems, the Cobra was establishing itself as an effective aerial weapons platform, despite its performance shortcomings compared to the AH-56 and design issues of its own. The cost estimates of the AH-56 increased substantially. By 1972, when the Cheyenne program was eventually cancelled to make way for the Advanced Attack Helicopter (AAH), the interim AH-1 "Snake" had built

15052-536: The operation, AH-1Ws flew combat missions from the deck of USS  San Antonio after that ship replaced Wasp in October 2016. In October 2020, the U.S. Marine Corps retired the last of its AH-1Ws after 34 years of service, having replacing the type with the Bell AH-1Z Viper . By the time of their retirement, the model had collectively accumulated 933,614 flight hours. In 1971, Iran purchased 202 examples of an improved AH-1J, named "AH-1J International", from

15194-599: The principal cannon armament of United States military fixed-wing aircraft for over sixty years. The M61 was originally produced by General Electric . After several mergers and acquisitions, it is produced by General Dynamics as of 2000 . At the end of World War II , the United States Army Air Forces began to consider new directions for future military aircraft guns. The higher speeds of jet-powered fighter aircraft meant that achieving an effective number of hits would be extremely difficult without

15336-571: The program and eventually procure the AH-64 Apache instead. Turkey had sought a new attack helicopter since the 1990s to replace their diminished Bell AH-1 Cobra and Bell AH-1 SuperCobra fleets. Following a highly protracted selection process, in September 2007, an order was issued for 51 TAI/AgustaWestland T129 ATAK helicopters, a variant of the A129 International. As a part of the deal with AgustaWestland, Turkish defense firm TAI acquired

15478-651: The purchase of attack helicopters from Eastern Europe in 1990 and 1991; Bulgaria and Russia rejected Chinese offers to purchase the Mil Mi-24. While attempting to import foreign designs failed, war games determined that attack helicopters had to be commanded by the army, rather than the air force. This led to the formation of the People's Liberation Army Ground Force Aircraft (PLAGFAF), with an initial strength of 9 Harbin Z-9s . The PLAGFAF conducted tactical experiments that would help define

15620-448: The purpose of providing a heavily armed and protected aerial vehicle that can perform a variety of combat roles, from reconnaissance to aerial assault missions. By the 1990s, the missile-armed attack helicopter evolved into a primary anti-tank weapon. Able to quickly move about the battlefield and launch fleeting "pop-up attacks", helicopters presented a major threat even with the presence of organic air defenses. The helicopter gunship became

15762-572: The pylon mounting was not rigid enough to prevent deflection when firing, and repeated use would misalign the pod on its pylon, making matters worse. A variant with much shorter barrels, designated the M195, was also developed for use on the M35 Armament Subsystem as used on the AH-1G Cobra helicopter . This variant fed from ammunition boxes fitted to the landing skid and was developed to provide

15904-785: The rebels from their hilltop strongholds during an offensive by the United Nations Force Intervention Brigade and the Military of the Democratic Republic of the Congo . M61 Vulcan The M61 Vulcan is a hydraulically , electrically, or pneumatically driven, six- barrel , air-cooled, electrically fired Gatling-style rotary cannon which fires 20 mm × 102 mm (0.787 in × 4.016 in) rounds at an extremely high rate (typically 6,000 rounds per minute). The M61 and its derivatives have been

16046-738: The rescue of USAF Captain Scott O'Grady , after his F-16 was shot down by a SAM in June 1995. During the twenty-first century, USMC Cobras participated in Operation Enduring Freedom in Afghanistan and in Operation Iraqi Freedom in the conflict in Iraq . While new replacement aircraft were considered as an alternative to major upgrades of the AH-1 fleet, Marine Corps studies showed that an upgrade

16188-502: The rights for future manufacturing of the T129; TAI intends to produce the T129 for export customers. Various components and avionics systems are intended to be replaced with indigenously-produced systems as they are developed. In 1984, the French and West German governments issued a requirement for an advanced multirole battlefield helicopter . A joint venture consisting of Aérospatiale and MBB

16330-589: The rotary cannon became the responsibility of Lockheed Martin Armament Systems. Lockheed Martin Armament Systems was later acquired by General Dynamics , which produces the M61 and its variants as of 2000 . Each of the cannon's six barrels fires once in turn during each revolution of the barrel cluster. The multiple barrels provide both a very high rate of fire—around 100 rounds per second—and contribute to prolonged weapon life by minimizing barrel erosion and heat generation. The average time between jams or failures

16472-405: The same manner as the Soviets did with their Mi-24s . Due to the post-Revolution weapons sanctions, Iranians had to make do with what was at hand: they equipped the AH-1Js with AGM-65 Maverick missiles and used them with some success in several operations. Starting from October 1980, the AH-1Js engaged in air-to-air combat with Iraqi Mil Mi-24 helicopters on several, separate occasions during

16614-414: The service also sought a more potent turret-mounted weapon. Initially, the Department of Defense had balked at providing the Marines with a twin-engine version of the Cobra in the belief that commonality with the Army's AH-1Gs outweighed the advantages of a different engine arrangement. However, the Marines won out; thus, during May 1968, Bell received a contract for 49 twin-engine AH-1J SeaCobras. The AH-1J

16756-414: The service's request for funding to purchase the AH-64 was denied by Congress that same year. As an alternative option, the Marines procured a more powerful version of the AH-1T. Other changes included modified fire control systems to carry and fire AIM-9 Sidewinder and AGM-114 Hellfire missiles. The new version, which was funded by Congress, received the AH-1W designation. During March 1986, deliveries of

16898-404: The sights of the fighter. The improved pods were self-powered and properly synchronized to the sights, while the USAF versions of the F-4 were hastily fitted with internal M61 cannons in a prominent fairing under the nose, well before the war ended (Navy Phantoms never received cannons, continuing to rely on air-to-air missiles alone). The next generation of fighters built post-Vietnam incorporated

17040-536: The twelve aircraft originally delivered to the SAAF was written off after an accident) Block 1F upgraded Rooivalk. The ninth and tenth Rooivalk attack helicopters were delivered in September 2012 following their upgrade to the Block 1F initial operating standard. The eleventh and final Rooivalk was delivered on 13 March 2013. The Indian Army deploys the Mil Mi-35 (export variant of Mi-24V) and HAL Rudra as of 2014. During

17182-469: The type on multiple occasions against Kurdistan Workers' Party (PKK) insurgents. On numerous occasions in the 1990s, USMC AH-1s were deployed during the Gulf War of the early 1990s, as well as for the United States invasion of Haiti in 1994, and the US intervention in the Yugoslav Wars in the late 1990s. In the twenty-first century, the type also saw action in the multi-decade War in Afghanistan , and

17324-573: The vicinity of Hon La (Tiger) Island. These were termed Marine Hunter-Killer (MARHUK) Operations and lasted from June to December 1972. As such, the type participated in the final American combat operations in Vietnam. Several AH-1Js were present to cover the evacuation of the US Embassy in Saigon in April 1975. During 1983, Marine Cobras took part in the invasion of Grenada . They were typically used to perform close air support and helicopter escort missions;

17466-553: The war, with one subtype of the Bücker Bestmann trainer—the 181C-3 —armed with four Panzerfaust 100 anti-tank grenade launchers, two under each of the low-winged monoplane's wing panels, for the concluding two months of the war in Europe. This sort of role, being undertaken by low-speed fixed-wing light aircraft was something that was also likely to be achievable after World War II, from

17608-477: Was Lockheed's AH-56 Cheyenne . As the Army began its acquisition of a dedicated attack helicopter, it sought options to improve performance over the continued use of improvised interim aircraft (such as the UH-1B/C). In late 1965, a panel of high-level officers was selected to evaluate several prototype versions of armed and attack helicopters to determine which provided the most significant increase in capability to

17750-402: Was a modified version of HAL Dhruv , free of any major modifications to the airframe to quickly create an armed variant for the Indian Army. The HAL Prachand is a purpose-built attack helicopter, expressly designed to overcome several operational shortcomings of prior attack rotorcraft. By 2010, the Indian Air Force was reportedly set to acquire 65 LCHs while the Indian Army's Aviation Corps

17892-412: Was also equipped with a more powerful gun turret in the form of the three-barrel 20 mm XM197 cannon, which was based on the six-barrel M61 Vulcan cannon. As an interim measure, the U.S. Army transferred 38 AH-1Gs to the Marines in 1969. During the 1970s, the Marine Corps requested greater load carrying capability in high temperatures for the Cobra. Bell used systems from its Model 309 to develop

18034-424: Was chosen, and was mounted ahead and to the right of the helicopter to allow the door to remain clear. The bazooka was successfully tested, although it was discovered that it would require shielding for the engine compartment, which was exposed in the model 47 and other early helicopters. The helicopter itself belonged to HMX-1, a Marine experimental helicopter squadron. In the mid-1960s, the U.S. Army concluded that

18176-409: Was continually relayed to update target information, assess the threat of Surface to Air missiles (SAM), and the presence of civilians, enabling real time changes to missions. In 2013, the South African National Defence Force announced that it would deploy Denel Rooivalk attack helicopters to the Democratic Republic of the Congo to support the United Nations Organization Stabilization Mission in

18318-436: Was delivered to the Army on 5 June 2006. In 1979, the Chinese military studied the problem of countering large armor formations. It concluded that the best conventional solution was to use attack helicopters. Eight Aérospatiale Gazelle armed with Euromissile HOT were procured for evaluation. By the mid-1980s, the Chinese decided a dedicated attack helicopter was required. At the time, they used civilian helicopters converted for

18460-499: Was faster and more powerful, but the AH-1J was more agile. There were even engagements between Iranian AH-1Js and Iraqi fixed-wing aircraft. The AH-1Js scored three confirmed kills against MiG-21s , claimed a Su-20 , and shared in the destruction of a MiG-23 —all using their 20 mm M197 cannon . During early 1984, an Iranian AH-1J Sea Cobra was shot down by an Iraqi Pilatus PC-7 during Operation Kheibar (Iranian pilots Reza Moghadam and Mohammad Yazdi were rescued). About half of

18602-404: Was introduced to the general public in December 2010 and subsequently entered service with the People's Liberation Army . In 1972, the Italian Army began forming a requirement for a light observation and anti-tank helicopter. Agusta had initially studied the development of a combat-orientated derivative of their existing A109 helicopter, however they decided to proceed with the development of

18744-400: Was issued to Bell. The type entered service during the final months of the US's involvement in the Vietnam War , seeing limited action in the theatre as a result. The USMC promptly sought greater payload capacity than that provided by the original Sea Cobra; thus the AH-1T, equipped with the dynamic systems of the Model 309 and a lengthened fuselage, was produced by Bell during the 1970s. In

18886-512: Was more successful with minimal losses. In October 2014, U.S. Army AH-64s and Air Force fighters participated in four air strikes on Islamic State units northeast of Fallujah. In June 2016, Apaches were used in support of the Iraqi Army's Mosul offensive and provided support during the Battle of Mosul , sometimes flying night missions supporting Iraqi operations. In 2011, France and Britain sent Eurocopter Tiger and AgustaWestland Apache attack helicopters to Libya. The primary objective of

19028-411: Was mostly from infantry-type weapons. AH-1Ws were involved in the rescue of Private First Class Jessica Lynch from an Iraqi hospital. In late August 2016, Marine AH-1W Cobras flying from USS  Wasp started flying combat missions over Sirte, Libya against the Islamic State of Iraq and the Levant in Libya , providing close air support for friendly militias on the ground. In the later stages of

19170-421: Was not a novel idea at the end of World War II, as Richard Jordan Gatling himself had done just that with a patent he filed in 1893. During World War I , a similar 12-barreled Fokker-Leimberger aircraft rotary machine gun, powered by either the aircraft engine or an electric motor, had been under development by the German Empire . In 1946, the Army issued General Electric a contract for "Project Vulcan",

19312-401: Was officially accepted into the state arsenal in 1972. Numerous versions have been developed to this day. In 1972, following completion of the Mi-24, development began on a unique attack helicopter with transport capability. The new design had a reduced transport capability (3 troops instead of 8) and was called the Mil Mi-28 . In 1977, a preliminary design of the Mil Mi-28 was chosen, in

19454-429: Was politically controversial in the United States; in April 1996, the purchase of ten additional AH-1Ws by Turkey was blocked by the Clinton administration . During late 2011, Turkey requested the purchase of three AH-1Ws from the USMC inventory. The AH-1s have been repeatedly used in combat against Kurdistan Workers' Party ( PKK ) insurgents. On 13 May 2016, PKK militants shot down a Turkish Army AH-1W SuperCobra using

19596-428: Was proposed to Iran in the late 1970s, but the overthrow of the Shah of Iran in the late 1970s resulted in the sale being canceled. In the early 1980s, the Marine Corps sought a new navalized helicopter; accordingly, it evaluated the Boeing AH-64 Apache attack helicopter over a two-week period in September 1981, which included shipboard operation tests. Furthermore, various concepts were studied at this time. However,

19738-503: Was soon replaced by the M61A1, with a linkless feed system. Depending on the application, the feed system can be either single-ended (ejecting spent cases and unfired rounds) or double-ended (returning casings back to the magazine). A disadvantage of the M61 is that the bulk of the weapon, its feed system, and ammunition drum make it difficult to fit it into a densely packed airframe. The feed system must be custom-designed for each application, adding 140 to 180 kg (300 to 400 lb) to

19880-422: Was subsequently chosen as the preferred supplier. According to statements by the French Defence Minister André Giraud in April 1986, the collaborative effort had become more expensive than an individual national programme and was forecast to take longer to complete as well. In July 1986, a government report into the project alleged that the development had become distanced from the requirements and preferences of

20022-416: Was the most affordable, most supportable and most effective solution for the Marine Corps light attack helicopter mission. During the opening phase of the 2003 invasion of Iraq , SuperCobras were deployed on the front lines, often flying in hunter-killer teams with Bell UH-1 Iroquois utility helicopters and other coalition aircraft. Reportedly, 46 of the 58 USMC AH-1s deployed sustained battle damage, which

20164-407: Was to also procure 114 LCHs for its own purposes. During February 2020, the LCH was declared ready for production, the final assembly line has been established at HAL's Helicopter Division in Bangalore. Prime minister Narendra Modi conducted the handover ceremony of HAL Prachand to the Indian Armed forces in Jhansi. The Iran–Iraq War of the 1980s saw "the most intensive use of the helicopters" in
