With respect to aircraft performance, a ceiling is the maximum density altitude an aircraft can reach under a set of conditions, as determined by its flight envelope .
104-499: The TAI/AgustaWestland T129 ATAK is a twin-engine, tandem seat, multi-role, all-weather attack helicopter based on the Agusta A129 Mangusta platform. It was developed by Turkish Aerospace Industries (TAI) in partnership with Leonardo S.p.A. The helicopter is designed for armed reconnaissance and attack missions in hot and high environments and rough geography in both day and night conditions. The ATAK programme
208-421: 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
312-537: 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
416-760: 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

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
728-539: 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
832-462: 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
936-498: 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
1040-487: 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
1144-646: 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,

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
1352-537: 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
1456-486: 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
1560-644: 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

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,

7176-443: 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
7280-440: 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
7384-439: 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
7488-683: The initial parts of the serial production T129 are manufactured in Turkey. On 16 July 2007, the Scientific and Technological Research Council of Turkey (TUBITAK), Meteksan Savunma Sanayii AŞ and Bilkent University formed a consortium to develop an advanced millimetre wave radar (MILDAR), similar to the Longbow and the IAI/ELTA radars, intended to enter service in 2009. MILDAR was successfully completed development in February 2012. In 2007, it
7592-430: The low indicated airspeed which can be sustained: although the true airspeed at an altitude is typically greater than indicated airspeed (IAS), the difference is not enough to compensate for the fact that IAS at which minimum drag is achieved is usually low, so a flight at an absolute ceiling altitude results in a low TAS as well, and therefore in a high fuel burn rate per distance traveled. The absolute ceiling varies with
7696-518: 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
7800-589: 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
7904-573: 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
8008-489: 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
8112-405: 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
8216-524: 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
8320-644: 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
8424-898: The purchase of 22 T129s. Additional sources claimed previous negotiations were suspended in 2018 due to US sanctions. In January 2013, a media report stated that South Korea 's attack helicopter competition included the T129 in the final three bidders with the Bell AH-1Z Viper and the Boeing AH-64 Apache . However, the AH-64E Apache was chosen in April 2013. Data from Turkish Aerospace Industries General characteristics Performance Armament Avionics Related development Aircraft of comparable role, configuration, and era Related lists Attack helicopter An attack helicopter
8528-664: 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
8632-448: 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
8736-461: 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 . Service ceiling Service ceiling is the density altitude at which the rate of climb drops below a prescribed value. The service ceiling is the maximum altitude of an aircraft during normal operations. Specifically, it
8840-459: 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
8944-478: The service ceiling as the pressure altitude at which the aircraft will have the capability of climbing at 50 ft/min (0.25 m/s) with one propeller feathered . Most commercial jetliners have a service (or certified) ceiling of under 45,000 ft (13,700 m) and some business jets about 51,000 ft (15.5 km; 9.7 mi). Before its retirement, the Concorde supersonic transport (SST) (as well as
9048-494: 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
9152-429: The war against insurgency. In September 2018, Brazil showed interest in acquiring T129 with army officials visiting Turkey. In March 2019, ten Brazilian Army pilots received certificates for completing T129 test flights at Forte Ricardo Kirk, Taubaté . In an Iraqi TV broadcast, the Iraqi defense minister announced in August 2021 that Iraq will acquire 12 T129 ATAK helicopters. In 2017, Pakistan indicated that it
9256-567: 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
9360-443: The weight of the aircraft. Hence, the aircraft will not have any excess capacity to climb further. Stated technically, it is the altitude where the maximum sustained (with no decreasing airspeed) rate of climb is zero. Compared to service ceiling, the absolute ceiling of commercial aircraft is much higher than for standard operational purposes. In the Concorde 's case, it was tested to be 68,000 ft (21 km; 12.9 mi). It
9464-482: 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
9568-529: 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
9672-545: Was begun to meet the requirements of the Turkish Armed Forces for an armed tactical reconnaissance and attack helicopter. The T129 is the result of the integration of Turkish-developed avionics , airframe modifications, and weapon systems onto the AgustaWestland A129 airframe, with upgraded engines, transmission and rotor blades. It is in use by the Turkish Army and other services including
9776-581: Was built by TAI for delivery in 2012, one year prior to the delivery of the previously ordered 51 helicopters. Designated T129A, these lack advanced anti-tank missiles; as a result of delays, they entered service in 2014. On 28 September 2009, the T129's maiden flight took place when the P1 prototype flew at AgustaWestland's facilities in Vergiate, Italy. On 19 March 2010, the first T129 prototype (P1) conducted high-altitude hover tests near Verbania , Italy following
9880-424: 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
9984-681: 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
10088-491: 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
10192-731: Was interested in possibly purchasing the T129 for the Pakistan Army Aviation Corps (PAAC), as a replacement to their ageing Bell AH-1F Cobra gunships; the PAAC had extensively tested the T129 and the Z-10ME in 2016. In May 2018, Turkey's ruling Justice and Development Party (AK Parti) announced that Pakistan is purchasing 30 T129s for US$ 1.5 billion, which Turkish Aerospace Industries (TAI) confirmed in July. However, Pakistan's T129 purchase has been politically complicated;
10296-464: 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
10400-571: 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
10504-457: 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
10608-462: Was reported that one helicopter will be kept by the Turkish Ministry of Defense and used as a systems development testbed while the remaining 50 T129s will be delivered to the Turkish Army. An optional 40 further T129s will be produced if necessary. These rotorcraft would be designated T129B. In November 2010, Turkey ordered an additional nine T129s, increasing its total on order to 60. These T129s were for an urgent Turkish Army operational requirement and
10712-515: 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
10816-627: 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
