The Center for Public Policy Analysis and non-governmental organisations (NGOs) as well as Laotian and Hmong human rights organisations, including the Lao Human Rights Council , Inc. and the United League for Democracy in Laos , Inc., have provided evidence that since the end of the Vietnam War , significant numbers of Vietnamese military and security forces continue to be sent to Laos, on
558-421: 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
744-643: A capable platform for countering enemy armour. The type was operated by the Israeli Air Force (IAF), with the First Attack Helicopter Squadron formally commencing on 1 December 1977. The service named the type as the "Tzefa" ( Hebrew : צפע , for Viper ). On 9 May 1979, the IAF's Cobras performed their first attack, firing four Orev missiles at a house near Tyre, Lebanon , that was occupied by militants. Israel's fleet of Cobras
930-537: 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
1116-760: 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
1302-490: 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
1488-667: A further 158 sustained some level of damage. The U.S. Marine Corps also operated the AH-1G Cobra in Vietnam for a short time before acquiring the twin-engine AH-1J Cobras . The AH-1Gs had been adopted by the Marines as an interim measure, a total of 38 helicopters having been transferred from the U.S. Army to the Marines in 1969. During Operation Urgent Fury, the invasion of Grenada in 1983 , several AH-1T Cobras were deployed to fly close air support and helicopter escort missions. On
1674-539: 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
1860-574: A greater level of survivability. Despite the Army's preference for the AAFSS program—for which Bell Helicopter was not selected to compete—the company persisted with their own idea of a smaller and lighter gunship, noting that Lockheed had little experience in developing rotorcraft and correctly predicted that it would encounter considerable difficulties. Bell employee Mike Folse played a key role in developing this new gunship, which he intentionally based around
2046-413: A grenade launcher in a ball turret on the nose, a 20 mm belly-mounted gun pod, and stub wings for mounting rockets or SS.10 anti-tank missiles. In June 1962, Bell displayed the mockup to US Army officials, hoping to solicit funding for further development; rival manufacturers issued protests to this approach, alleging that it was an attempt by Bell to circumvent the competitive process. Nevertheless,

#17327800046742232-893: A hard time remaining within the Mekong Delta area due to the extensive use of the Phoenix Program . Although the PAVN lost militarily to the US forces and ARVN in the south, the political impact of the war in the United States was strong. Public demonstrations increased in ferocity and quantity after the Tet Offensive. During 1970, the 5th, 7th and 9th Divisions fought in Cambodia against U.S., ARVN, and Cambodian Khmer National Armed Forces but they had gained new allies:
2418-816: A large extent. The PAVN was first conceived in September 1944 at the first Revolutionary Party Military Conference as the Propaganda Unit of the Liberation Army (alternatively translated as the Vietnam Propaganda Liberation Army , Việt Nam Tuyên truyền Giải phóng Quân ) to educate, recruit and mobilise the Vietnamese to create a main force to drive the French colonial and Japanese occupiers from Vietnam. Under

During the Vietnamese Lunar New Year Tết holiday starting on 30 January 1968, the PAVN/VC launched a general offensive in more than 60 cities and towns throughout south of Vietnam against the US Army and Army of the Republic of Vietnam (ARVN), beginning with operations in
2790-462: 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
2976-569: 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

The withdrawn AH-1s were typically offered to other potential operators, usually NATO allies. The Army retired the AH-1 from its reserves in September 2001. The retired AH-1s were then disposed of, often through sales to overseas customers; the final portion of
3348-487: 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
3534-591: 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,
3720-525: A quick solution. Submissions came in for armed variants of the Boeing-Vertol ACH-47A , Kaman HH-2C Tomahawk , Piasecki 16H Pathfinder , Sikorsky S-61 , and the Bell 209. During April 1966, Bell's submission emerged victorious in an evaluation against the other rival helicopters. The US Army promptly signed the first production contract, ordering an initial batch of 110 aircraft. By the end of

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
4464-576: A single squadron was deployed in 1994. Pakistani Cobras subsequently saw action in Sierra Leone. By 2013, Pakistan reportedly operated a fleet of 35 AH-1F helicopters. Maintaining these aircraft has been difficult, but possible through commercial channels. Additionally, the US government provided $ 750,000 (~$ 967,428 in 2023) through 2013 to update the existing AH-1F/S Cobra fleet. However, controversy over how much of this funding has actually been spent on Pakistan's Cobras has also been present throughout
4650-537: 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
4836-486: 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
5022-509: A team normally comprised a single OH-6 flying slow and low to find enemy forces. If the OH-6 drew fire, the Cobra could strike at the then revealed enemy. On 12 September 1968, Capt. Ronald Fogleman was flying an F-100 Super Sabre when the aircraft was shot down and he ejected 200 miles (320 km) north of Bien Hoa. Fogleman became the only pilot to be rescued by holding on to an Army AH-1G's deployed gun-panel door. Bell built 1,116 AH-1Gs for
5208-644: 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
5394-467: 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

It commonly provided fire support to friendly ground forces, escorted transport helicopters, and flew in "hunter killer" teams by pairing with Hughes OH-6A Cayuse scout helicopters. In the Vietnam War alone, the Cobra fleet cumulatively chalked up in excess of one million operational hours; roughly 300 AH-1s were also lost in combat. In addition to
13020-423: The AH-1F. The AH-1F integrated numerous countermeasures, including an infrared jammer, a radar jammer, and a hot plume exhaust suppressor. The U.S. Marine Corps (USMC) quickly became interested in the Cobra, opting to order an improved twin-engine version in 1968 under the designation AH-1J. During the early 1970s, the USMC proceeded to order an upgraded model, the AH-1T, which featured dynamic elements derived from
13206-419: The Army was interested and awarded Bell a proof-of-concept contract in December 1962. Bell modified a Model 47 into the Model 207 Sioux Scout which first flew in July 1963. The Sioux Scout had all the key features of a modern attack helicopter: a tandem cockpit , stub wings for weapons, and a chin-mounted gun turret . After evaluating the Sioux Scout in early 1964, the Army was impressed but also felt that it
13392-606: 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
13578-695: The Chinese People's Liberation Army . The first six divisions (308th, 304th, 312th, 316th, 320th, 325th) became known as the original PAVN 'Steel and Iron' divisions. In 1954, four of these divisions (the 308th, 304th, 312nd, 316th, supported by the 351st Division's captured US howitzers) defeated the French Union forces at the Battle of Dien Bien Phu, ending 83 years of French rule in Indochina. The French Foreign Legion had been deployed to combat
13764-492: The Cobra have been developed, such as the twin engined AH-1 SeaCobra/SuperCobra and the experimental Bell 309 KingCobra . Furthermore, surplus AH-1 helicopters have been reused for other purposes, including civilian ones; numerous examples have been converted to perform aerial firefighting operations. Closely related to the development of the Bell AH-1 is the story of the Bell UH-1 Iroquois transport helicopter—an icon of
13950-443: The Cobra was intentionally made to be sleek and be akin to that of a jet fighter. Aviation author Stanley McGowen observed that its appearance differed radically from any prior rotorcraft designed by Bell, possessing a relatively narrow fuselage and a then-unusual cockpit arrangement. This cockpit was covered by a large fighter-like canopy and its occupants protected by armor, such included tempered-steel seats and personal body armor. It
14136-658: The Communist Party of Vietnam ) is the de facto Commander and now is Nguyễn Phú Trọng . The Minister of National Defence oversees operations of the Ministry of Defence , and the PAVN. He also oversees such agencies as the General Staff and the General Department of Logistics. However, military policy is ultimately directed by the Central Military Commission of the ruling Communist Party of Vietnam . The Vietnamese People's Army
14322-912: 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
14508-627: 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
14694-704: 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
14880-734: 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
15066-689: The Japanese and other opponents. For instance, the PAVN's July 19, 1945 attack at Tam Dao internment camp in Tonkin saw 500 soldiers kill fifty Japanese soldiers and officials, freeing French civilian captives and escorting them to the Chinese border. The PAVN also fought the Japanese 21st Division in Thai Nguyen that year, and regularly raided rice storehouses to alleviate an ongoing famine . There
15252-558: 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
15438-459: 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
15624-490: The Ministry of National Defence organises international operations of the PAVN. Apart from its occupation of half of the disputed Spratly Islands , which have been claimed as Vietnamese territory since the 17th century, Vietnam has not officially had forces stationed internationally since its withdrawal from Cambodia and Laos in early 1990. The effectiveness of the People's Army of Vietnam Special Operation Forces during
15810-643: The PAVN Ground Force had four 'Strategic Army Corps' in the early 1990s, numbering 1–4, from north to south. 1st Corps , located in the Red River Delta region, consisted of the 308th (one of the six original 'Steel and Iron' divisions) and 312th Divisions, and the 309th Infantry Regiment. The other three corps, 2 SAC, 3 SAC, and 4 SAC, were further south, with 4th Corps , in Southern Vietnam, consisting of two former LASV divisions,
15996-815: The Philippines for counter terrorism operations. The offer was later reduced to two units, which the Philippine government accepted. On 26 November 2019, an Antonov An-124 airlifter carried the two Bell AH-1F Cobras from Jordan to Clark International Airport/Clark Air Base. The helicopters are reportedly painted in a light grey livery similar to the paint scheme of the PAF's AgustaWestland AW109E armed helicopters. PAF AH-1s conducted airstrikes on communist insurgent positions as part of OPLAN "Wrath of Polaris 2" conducted by Joint Task Force Tala in Gonzaga, Cagayan. In 2003,
16182-525: 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
16368-706: 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,
16554-760: 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,
16740-806: The Turkish T129 , the Chinese CAIC Z-10 , and the Russian Mi-35 Hind . In November 2014, Russia approved the sale of Mi-35M helicopters to Pakistan. In April 2015, China delivered three Z-10s to Pakistan. During the same month, the US Department of State approved the sale of 15 AH-1Zs and associated equipment to Pakistan. During October 2017, the T129 was also reported to be a contender for further orders. The Jordanian government offered to provide up to four surplus AH-1F Cobras to
16926-478: The U.S. Army between 1967 and 1973, and the Cobras chalked up over a million operational hours in Vietnam; the number of Cobras in service peaked at 1,081. Out of nearly 1,110 AH-1s that were delivered between 1967 and 1973, approximately 300 were lost to a combination of combat and accidents during the conflict. During Operation Lam Son 719 in Southeastern Laos , 26 U.S Army AH-1Gs were destroyed while
17112-450: The U.S., and suffering from stresses caused by dwindling aid, the ARVN was ill-prepared to confront the highly motivated PAVN, and despite the on paper superiority of the ARVN, the PAVN quickly secured victory within two months and captured Saigon on 30 April 1975, ending the 20 year Vietnam war. After national reunification, the LASV was officially merged into PAVN on 2 July 1976. Towards
17298-731: The UH-1 Iroquois, AH-56 Cheyenne, OH-58 Kiowa, and later helicopters. Within its first decade of service, the US Army had put the original Cobra model through various exercises and operations, which highlighted both the attack helicopter's promise and areas in which it could be improved. By 1972, the US Army openly sought an improved anti-armor capability. Under the Improved Cobra Armament Program (ICAP), trials of eight AH-1s fitted with TOW missiles were conducted in October 1973. After passing qualification tests
17484-669: 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
17670-619: 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
17856-494: The US Army would be intruding into their domain by developing a complex armed aerial combatant, and ought to be largely restricted to transport aircraft. Meanwhile, some Army officials were concerned that the USAF did not take the close air support (CAS) mission as seriously as it ought to, and that response times of 30 minutes or more for fixed-wing aircraft would be unacceptable. Bell had been investigating helicopter gunships since
18042-479: The US Army, various other branches of the US military also opted to acquire the type, particularly the United States Marine Corps . Furthermore, numerous export sales were completed with several overseas countries, including Israel , Japan , and Turkey . For several decades, the AH-1 formed the core of the US Army's attack helicopter fleet, seeing combat in Vietnam, Grenada , Panama , and
18228-485: The US Forest Service acquired 25 retired AH-1Fs from the US Army. These have been designated Bell 209 and are being converted into Firewatch Cobras with infrared and low light sensors and systems for real time fire monitoring. The last two Firewatch Cobras were retired in October 2021. Attack helicopter An attack helicopter is an armed helicopter with the primary role of an attack aircraft , with
18414-562: The Vietnam War proceeded, pressure accumulated in favor of the Model 209. Attacks on US forces were increasing and, by the end of June 1965, there were already 50,000 US ground troops in Vietnam. 1965 was also the deadline for AAFSS selection, but the program would become stuck in technical difficulties and political bickering. The US Army needed an interim gunship for Vietnam and it approached five separate companies with its request to provide
18600-734: The Vietnam War saw them instruct various other countries and Marxist rebel groups. From the 1970s to 1990s, they covertly provided training at the PAVN Sapper Training School in via Vietnamese sapper advisors assigned to the Cuban Army 's Sapper School in Cuba, and, during the 1980s, by a secret Vietnamese sapper training team stationed in Nicaragua . In addition to training Cambodian , Laotian , Soviet, and Cuban military personnel, their publications revealed that among
18786-561: The Vietnamese insurgency during the First Indochina War. However, some of the legionnaires, such as Stefan Kubiak , deserted after witnessing torture of Vietnamese peasants at the hands of French troops and began fighting for the Việt Minh , volunteering to join the PAVN. Soon after the 1954 Geneva Accords , the 330th and 338th Divisions were formed by southern Viet Minh members who had moved north in conformity with that agreement, and by 1955, six more divisions were formed:
18972-644: 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
19158-699: 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
19344-519: The abortive Bell 309 KingCobra ; as such, it featured a longer fuselage and tailboom. These dynamic changes were combined with the adoption of heavier armaments, which provided the USMC with an effective anti-armor capacity, unlike the preceding model. The USMC's interest in the Cobra would lead to the production of more twin-engine variants of the helicopter. The Bell AH-1 Cobra is a dedicated attack helicopter, built to provide close air support and to escort friendly troop transports. The visual design of
19530-593: 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
19716-664: The army was referred to by its opposition forces as the North Vietnamese Army (NVA; Vietnamese : Quân đội Bắc Việt ), serving as the military force of the Democratic Republic of Vietnam . This allowed writers, the U.S. military, and the general public, to distinguish northern communists from the southern communists, called Viet Cong (VC), or more formally the National Liberation Front. However, both groups ultimately worked under
19902-673: The army was renamed the Vietnam National Defence Force ( Việt Nam Vệ quốc Đoàn ). At this point, it had about 1,000 soldiers. On 22 May 1946, the army was called the National Army of Vietnam ( Quân đội Quốc gia Việt Nam , not to be confused with the opposite Vietnamese National Army of the France-associated State of Vietnam which had a synonymous English name and exactly the same Vietnamese name). Lastly, in 1950, it officially became
20088-504: The beginning, the South Vietnamese repulsed the main assaults with U.S. air support. Still North Vietnam retained some South Vietnamese territory. Nearly two years after the full U.S. withdrawal from Indochina in accordance with the terms of the 1973 Paris Peace Accords , the PAVN launched a Spring offensive aimed at overthrowing the South Vietnamese government and uniting Vietnam under communist rule. Without direct support of
20274-829: The border region to try and draw US forces and ARVN troops out of the major cities. In coordinated attacks, the U.S Embassy in Saigon , Presidential Palace, Headquarters of the Joint General Staff and Republic of Vietnam Navy , TV and Radio Stations, Tan Son Nhat Air Base in Saigon were attacked by commando forces known as "đặc công". This offensive became known as the " Tet Offensive ". The PAVN sustained heavy losses of its main forces in southern military zones. Some of its regular forces and command structure had to escape to Laos and Cambodia to avoid counterattacks from US forces and ARVN, while local guerrillas forces and political organisations in South Vietnam were exposed and had
20460-534: 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
20646-666: The concept's detailed design. Mating the proven transmission, the "540" rotor system of the UH-1C augmented by a Stability Control Augmentation System (SCAS), and the T53 turboshaft engine of the UH-1 with the design philosophy of the Sioux Scout, Bell produced the Model 209 . It largely resembled the "Iroquois Warrior" mockup, particularly in its cockpit and tail boom; in broad visual terms, there
20832-479: The conflict, it was decided to remove the rocket pods and increase the amount of ammunition carried for the cannon instead. Other operational changes included a greater emphasis on cooperation with ground units to avoid friendly fire incidents. Largely due to a US embargo that prevented the purchase of further Cobras, Israel procured alternative platforms instead, including around 20 McDonnell Douglas MD 500 Defenders in late 1979. Between 1983 and 1985, by which time
21018-555: The country, to fight the enemy at times and places of their own choice. The massive expansion of American military presence in Vietnam opened a new era of war from the air. The linchpin of US Army tactics was the helicopters, and the protection of those helicopters became a vital role. It became clear that unarmed troop helicopters were vulnerable against ground fire from Viet Cong and North Vietnamese troops, particularly as they approached landing zones to disembark or embark troops. Without friendly support from artillery or ground forces,
21204-570: The course of the mission. Much of the Cobra's armaments could be installed upon the multiple hardpoints that were attached to the stub wings set on either side of the fuselage. In comparison to armed UH-1s, the Cobra would typically have carried twice as much ammunition and arrive on station in half the time, it also had three times the loiter time, which enabled the type to arrive in a designated landing zone ahead of transport helicopters to clear it, provide support fire while they are present, and to continue fighting as they withdraw. The slim profile of
21390-406: The design were incorporated after the Cobra had entered service. The principal amongst these changes was the repositioning of the tail rotor from the helicopter's left side to the right, which facilitated an increase in the effectiveness of the tail rotor. The AH-1 was the first U.S. Army helicopter not named for a Native American people since the practice began with the H-13 Sioux and continued with
21576-431: The destruction of Champa as an independent nation to a level that it did not exist anymore; total destruction of Luang Prabang ; the decline of Cambodia which resulted in Vietnam's annexation of Mekong Delta and wars against Siam. In most of its history, the Royal Vietnamese Armed Forces was often regarded to be one of the most professional, battle-hardened and heavily trained armies in Southeast Asia as well as Asia in
21762-431: 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
21948-409: The early 1990s, and supplemented them with 32 ex-US Army Cobras. These additional units included several TAH-1P trainers while the majority were brought up to the AH-1F standard. During the 2010s, Turkish Cobras have repeatedly seen combat in operations against Kurdish insurgents around Turkey's borders with both Syria and Iraq. Two Cobras were reportedly lost to enemy fire during these operations. Amid
22134-452: 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
22320-540: The embargo had been lifted, 24 new Cobras were purchased; the expanded fleet enabled the creation of a second squadron, known as the Fighting Family Squadron, on 1 June 1985. During 1990, the IAF received its first Boeing AH-64 Apache attack helicopters, having acquired a fleet of 42 by 2000. At the time of the Apache's procurement, there was considerable political controversy over the IAF's decision to overlook upgrades to its existing Cobra fleet in favour of acquiring an entirely separate model of attack helicopter. Throughout
22506-466: The existing UH-1 on the rationale that, while the Army could not purchase a completely original helicopter without a formal design competition, the service was able to procure a modification of an aircraft that was already in its inventory without invoking such hurdles. This initiative quickly caught the approval of Bell's senior management team. In January 1965, Bell elected to invest $ 1 million (equivalent to $ 7.38 million in 2023) to proceed with
22692-417: The first day of the invasion, two of the four Cobras involved were lost to anti-aircraft fire in the attack on Fort Frederick. During 1989, Army Cobras participated in Operation Just Cause, the U.S. invasion of Panama . It operated alongside its eventual successor in US Army service, the Boeing AH-64 Apache , for the first time during the combat in Panama. During Operations Desert Shield and Desert Storm in
22878-417: 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
23064-588: The first involvement of Vietnam into a United Nations ' mission abroad. Vietnamese peacekeepers were also sent to the Central African Republic . From 2022, Vietnam has deployed its first military engineer unit to the peacekeeping missions in Abyei . As an effort to help Turkey overcome the consequences of the 2023 earthquake, PAVN has sent 76 servicemen of the Border Guard , Army Medic , and Engineering Corps (alongside personnel from Public Security ) to participate in humanitarian assistance and disaster relief including search-and-rescue missions. This
23250-425: The first major steps to prepare infiltration routes into South Vietnam were taken; Group 559 was established, a logistical unit charged with establishing routes into the south via Laos and Cambodia , which later became famous as the Ho Chi Minh trail . At about the same time, Group 579 was created as its maritime counterpart to transport supplies into the South by sea. Most of the early infiltrators were members of
23436-406: The fleet was liquidated in 2010. Some were also given to the USDA's Forest Service . The US Marine Corps retired the AH-1W SuperCobra in 2020, and continues to operate the AH-1Z Viper . Israel was an early export customer for the Cobra, purchasing six AH-1Gs from the US Army. The government was keen to procure a capable attack helicopter as recent combat in the Yom-Kippur War had shown a need for
23622-411: The following year, Bell was contracted with upgrading 101 AH-1Gs to the TOW-capable AH-1Q configuration. While early-production examples were not compatible with night vision goggles , the cockpit instrumentation of later Cobras was altered to facilitate their use. Further variants of the Cobra were promptly developed, with both new-build models and early production examples being modified to incorporate
23808-421: The foreign revolutionary forces that received training in sapper tactics, bomb-making, and the use of weapons and explosives, were members of the Marxist El Salvadoran FMLN ( Farabundo Marti National Liberation Front ), the Chilean MIR ( Movement of the Revolutionary Left ) fighting against the dictatorial regime of Augusto Pinochet , as well as the Colombian FARC ( Revolutionary Armed Forces of Colombia ) movement,
23994-443: 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
24180-440: 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
24366-406: The guidelines of Hồ Chí Minh , Võ Nguyên Giáp was given the task of establishing the brigades and the Propaganda Unit of the Liberation Army came into existence on 22 December 1944. The first formation was made up of thirty-one men and three women, armed with two revolvers, seventeen rifles, one light machine gun, and fourteen breech-loading flintlocks. It fought the PAVN's first ever engagement at
24552-420: The helicopter allegedly provided defensive benefits by making it harder for opponents to accurately hit it with small arms fire, although man-portable air-defense system (MANPADS) did prove to be effective against the Cobra. Particularly vulnerable areas included the tail rotor drive shaft and the main transmission. Typically, the Cobra would avoid hovering at any point in an active engagement; instead, emphasis
24738-431: The improvements. During March 1978, the US Army opted to procure a batch of 100 new-build Cobras that featured a new T-shaped instrument panel, improved composite rotor blades, revised transmission and gearboxes, the M128 helmet-mounted sight, and the M28A3 armament system. A major feature was the adoption of a more powerful version of the T53 engine. Designated AH-1S, the Cobra was upgraded in three stages, culminating with
24924-439: 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
25110-457: The intense fighting of the conflict. US Cobras were deployed in further operations across the 1990s. Army Cobras provided support for the US humanitarian intervention during Operation Restore Hope in Somalia in 1993. They were also employed during the US invasion of Haiti in 1994. During the 1990s, the US Army gradually phased out its Cobra fleet, completely retiring the type from active service in March 1999. The service, which had long sought
25296-421: The late 1950s, paying particular attention to the Algerian War , in which French forces mounted weapons onto helicopters to fight the growing insurgency. The company created a mockup of its D-255 helicopter gunship concept, named "Iroquois Warrior". The Iroquois Warrior was planned to be a purpose-built attack aircraft based on UH-1B components with a new, slender airframe and a two-seat, tandem cockpit. It featured
25482-413: The late 1980s. In 2001, nine additional ex-US Army Cobras were acquired to supplement the fleet. During 2010, Jordan transferred 16 AH-1F helicopters to Pakistan under a US-sponsored support program that provided Islamabad with 40 AH-1 refurbished helicopters. In late 2014, Israel and Jordan came to an agreement under which the former transferred 16 ex-IAF Cobras to the Royal Jordanian Air Force . The deal
25668-403: The main forces and the local forces. During peacetime, the standing forces are minimised in number, and kept combat-ready by regular physical and weapons training, and stock maintenance. Within PAVN the Ground Force have not been established as a separate full Service Command, thus all of the ground troops, army corps, military districts and the specialised arms are under the responsibility of
25854-410: 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
26040-402: 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
26226-451: 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
26412-489: 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
26598-405: 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
26784-420: 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
26970-424: The only way to pacify a landing zone was from the air, preferably with an aircraft that could closely escort the transport helicopters, and loiter over the landing zone as the battle progressed. By 1962, a small number of armed UH-1As were used as escorts, armed with multiple machine guns and rocket mounts. However, these makeshift gunships came with considerable tradeoffs, particularly being barely able to keep up with
27156-458: 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
27342-462: The project's go-ahead and slightly under budget. This first flight was witnessed by around 20 US Army officials, the service having had no awareness of the project's existence prior to this, and rapidly drew the government's attention. One early test flight was met with a reportedly enthusiastic visit by US secretary of defense Robert McNamara . Bell claimed at this phase of the project that production units could be ready for service within one year. As
27528-503: 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
27714-448: 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
27900-440: 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 . North Vietnamese Army The People's Army of Vietnam ( PAVN ), officially the Vietnam People's Army ( VPA ; Vietnamese : Quân đội nhân dân Việt Nam , lit. 'Military of and for the people of Vietnam ' ), also recognized as
28086-422: The requirement. It was out of the AAFSS program that the Lockheed AH-56 Cheyenne emerged, a heavy attack helicopter with high speed capability. During testing, it proved to be too sophisticated and costly, and was ultimately canceled in 1972 after ten years of development. In its place, the Advanced Attack Helicopter program was launched. Under this initiative, the Army sought a conventional attack helicopter with
28272-406: 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
28458-401: The same command structure. The Viet Cong had its own military forces called the Liberation Army of South Vietnam (LASV). It was practically considered a branch of the PAVN by the North Vietnamese. In 1976, following the political reunification of Vietnam, LASV was officially disbanded and merged into the so-called NVA to form the existing incarnation of PAVN, serving as the national military of
28644-517: The second half of the 20th century the armed forces of Vietnam would participate in organised incursions to protect its citizens and allies against aggressive military factions in the neighbouring Indochinese countries of Laos and Cambodia, and the defensive border wars with China. The PAVN has been actively involved in Vietnam's workforce to develop the economy of Vietnam by co-ordinating national defence. It has regularly sent troops to aid with natural disasters such as flooding, landslides etc. The PAVN
28830-439: The start of the 2009 Southeast Asian Games in Vientiane , the PAVN undertook a major troop surge in key rural and mountainous provinces in Laos where Lao and Hmong civilians and religious believers, including Christians, have sought sanctuary. In 2014, Vietnam had requested to join the United Nations peacekeeping force , which was later approved. The first Vietnamese UN peacekeeping officers were sent to South Sudan , marked
29016-428: The strategic aims were adjusted to meet the new reality. We had to change our plan and make it different from when we fought the Saigon regime, because we now had to fight two adversaries — the United States and South Vietnam. We understood that the U.S. Army was superior to our own logistically, in weapons and in all things. So strategically we did not hope to defeat the U.S. Army completely. Our intentions were to fight
29202-499: The troop transports they were intended to protect. While some officials within the Pentagon, particularly those within the US Army, had recognized the potential value of purpose-built armed rotary aircraft as early as 1962 and were keen to see such a vehicle developed promptly, the issue was complicated in part due to inter-service politics. The United States Air Force (USAF) largely held the opinion that most forms of US military aircraft should be operated only by their service, and that
29388-438: 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
29574-445: The unified state of Socialist Republic of Vietnam. The first historical record of Vietnamese military history dates back to the era of Hồng Bàng , the first recorded state in ancient Vietnam to have assembled military force. Since then, military plays a crucial role in developing Vietnamese history due to its turbulent history of wars against China, Champa , Cambodia, Laos and Thailand. The Southern expansion of Vietnam resulted in
29760-404: The war, with one subtype of the Bücker Bestmann trainer—the Bü 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
29946-419: The year, rapid follow-on orders had increased this to 500 Cobras. Bell added "Cobra" to the UH-1's Huey nickname to produce its HueyCobra name for the 209. The Army applied the Cobra name to its AH-1G designation for the helicopter. The Bell 209 demonstrator was used for the next six years to test weapons and fit of equipment. An additional use for the demonstrator was participating in marketing initiatives. It
30132-427: 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
30318-402: 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
30504-403: Was also backed by the 11th Battalion that later became the main force of the 312th Division . In late 1951, after launching three campaigns against three French strongpoints in the Red River Delta , the PAVN refocused on building up its ground forces further, with five new divisions, each of 10–15,000 men, created: the 304th Glory Division at Thanh Hóa , the 312th Victory Division in Vinh Phuc,
30690-410: Was also modified to match the AH-1 production standard by the early 1970s. The demonstrator was retired to the Patton Museum at Fort Knox , Kentucky and converted to approximately its original appearance. The Bell 209 design was modified in several respects for production. The retractable skids were replaced by simpler fixed skids; this was not due to any recorded design flaw or serviceability, but it
30876-455: Was another separate communist army called the National Salvation Army ( Cứu quốc quân ) which was founded and commanded by Chu Văn Tấn on 23/2/1941. On 15/5/1945 the Propaganda Liberation Army merged with the National Salvation Army into the Vietnam Liberation Army ( Việt Nam Giải phóng Quân ) on 15 May 1945. The Democratic Republic of Vietnam was proclaimed in Hanoi by Ho Chi Minh and Vietminh on 2 September 1945. Then in September,
31062-403: Was becoming increasingly clear that the South Vietnamese government was solidifying its position as an independent republic under Ngô Đình Diệm , who staunchly opposed the terms of the Geneva Accords, which required a national referendum on unification of north and south Vietnam under a single national government. North Vietnam prepared to settle the issue of unification by force. In May 1959,
31248-424: 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
31434-414: Was considerably older than the Apaches, which contributed to several fatal crashes of the type. The Cobras were also more expensive to maintain than UAVs and their use exposed pilots to attacks from man-portable air-defense systems operated by guerrilla groups. Around the same time frame, the IAF also pursued upgrades to its AH-64 fleet. In late 2014, Israel transferred 16 of the recently-withdrawn Cobras to
31620-409: 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
31806-434: Was declared operational on 6 October 1967. The Army operated the Cobra continuously up to the U.S. withdrawal from South Vietnam in 1973. Typically, the AH-1 provided fire support for ground forces and escorted transport helicopters, in addition to other roles, including aerial rocket artillery (ARA) battalions in the two Airmobile divisions. They also formed "hunter killer" teams by pairing with OH-6A Cayuse scout helicopters;
31992-436: 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
32178-411: Was feared that the landing gear bay could become inundated with mud. Furthermore, a new wide-chord rotor blade was adopted. It was also decided that a plexiglass canopy should replace the Model 209's armored glass canopy, which was heavy enough to negatively impact performance. The umbrella-shaped dive brake was deleted, having reportedly self-destructed during its first test flight. Numerous changes of
32364-411: Was initially considered a variant of the H-1 line, resulting in the G series letter. The first six AH-1s arrived at Bien Hoa Air Base , South Vietnam on 30 August 1967 for combat testing by the U.S. Army Cobra New Equipment Training Team. On 4 September, the type scored its first combat kill by sinking a sampan boat, killing four Viet Cong . The first AH-1 unit, the 334th Assault Helicopter Company,
32550-404: 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
32736-512: 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
32922-401: 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
33108-438: Was operated by both a pilot and gunner, who were seated in a stepped tandem arrangement in which the commander was placed in the rear seat while the gunner occupied the forward position. This forward position provided a higher level of visibility to that of the rear seat. Both positions were provided with flying controls while both crew would typically be certified pilots, enabling control of the Cobra to be exchanged quickly through
33294-427: Was particularly active on the Lebanon front, having participated in the fighting there for in excess of 20 years. They were intensively used during the 1982 Lebanon War to destroy Syrian armor and fortifications alike, being reportedly responsible for the destruction of dozens of Syrian ground vehicles. In one operation alone, a pair of IAF Cobras destroyed three enemy tanks and one truck. Based upon its performance in
33480-493: Was placed on maintaining speed and mobility. The gunner often fired the chin-mounted cannon with the intention of suppressing hostile targets in between barrages of 2.75-inch rockets, held in pods upon the stub wings, which were fired by the back-seater. It was unusual for Cobras to operate alone; instead, two or more would be dispatched and teamwork encouraged, leading to hunter-killer tactics being used to flush out and eliminate ground targets. Pairings with other helicopters, such as
33666-412: Was publicly stated to be for the purpose of increasing border security, which was viewed as a pressing concern of both nations due to the threats posed by Islamic State (IS) militants, as well as by other insurgent groups, at that time. The Royal Jordanian Air Force has at least one squadron of Cobras in service, and is supposed to have used them in combat in Iraq and Syria. Turkey bought ten AH-1Ws in
33852-414: Was relatively little shared between the proposed design and the UH-1. Despite appearance, much of the Model 209's major elements, such as the tail rotor and much of the dynamic systems, were identical. Roughly 80 percent of its components already had existing Huey part numbers. On 3 September 1965, Bell rolled out its Model 209 prototype, and four days later it made its maiden flight, only eight months after
34038-406: Was shaped to fulfill a need for a dedicated armed escort for transport helicopters, giving the latter greater survivability in contested environments. On 7 September 1965, the Model 209 prototype performed its maiden flight ; after rapidly gaining the support of various senior officials, quantity production of the type proceeded rapidly with little revision. During June 1967, the first examples of
34224-422: 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
34410-407: 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
34596-406: Was undersized, underpowered, and that the Sioux Scout was generally not suited for practical operations. The Army's solution to the shortcomings of the Sioux Scout was to launch the Advanced Aerial Fire Support System (AAFSS) competition. This called for a heavily armed helicopter capable of at least 200 miles per hour (320 km/h). A total of seven companies, including Bell, opted to respond to
