Первоначально «Чинук» был разработан компанией Vertol, которая в 1957 году начала работу над новым вертолетом с тандемным винтом, получившим обозначение Vertol Model 107 или V-107. Примерно в то же время Министерство армии США объявило о своем намерении заменить поршневым двигателем с Sikorsky CH-37 Mojave на новый вертолет с газотурбинным двигателем. В июне 1958 года армия США заказала у Вертола небольшое количество V-107 под обозначением YHC-1A ; После испытаний некоторые армейские чиновники сочли его слишком тяжелым для штурмовых операций и слишком легким для транспортных целей. В то время как YHC-1A будет улучшен и принят на вооружение Корпуса морской пехоты США как CH-46 Sea Knight , армия искала более тяжелый транспортный вертолет и заказала увеличенную модификацию V-107 с обозначением Vertol Model 114. Первоначально обозначенный Как YCH-1B , 21 сентября 1961 года опытный винтокрылый аппарат совершил свой первый полет . В 1962 году HC-1B был переименован в CH-47A в соответствии с системой обозначения самолетов Tri-Service США 1962 года. .
«Чинук» имеет несколько средств погрузки различных грузов, в том числе несколько дверей в фюзеляже, широкую погрузочную рампу, расположенную в задней части фюзеляжа, и в общей сложности три внешних подфюзеляжных грузовых крюка для перевозки подвешенных грузов. Обладая максимальной скоростью 170 узлов (200 миль в час; 310 км/ч), после ввода в эксплуатацию в 1962 году этот вертолет был значительно быстрее, чем современные вертолеты общего назначения и ударные вертолеты 1960-х годов , и до сих пор остается одним из самых быстрых вертолетов в мире. Американский инвентарь. С момента его появления также были разработаны улучшенные и более мощные версии Chinook; одним из наиболее серьезных вариантов производства был CH-47D, который впервые поступил на вооружение в 1982 году; Усовершенствования по сравнению со стандартом CH-47C включали модернизированные двигатели, композитные лопасти несущего винта, перепроектированную кабину для снижения рабочей нагрузки, улучшенные и резервные электрические системы и авионику, а также внедрение усовершенствованной системы управления полетом. Он остается одним из немногих самолетов, разработанных в начале 1960-х годов, наряду с самолетами. Грузовой самолет Lockheed C-130 Hercules , который находится в производстве и на вооружении уже более 60 лет.
В 1957 году компания Vertol начала работу над новым вертолетом с тандемным винтом, получившим обозначение Vertol Model 107 или V-107. [ 3 ] [ 4 ] В июне 1958 года армия США заключила с компанией Vertol контракт на приобретение небольшого количества винтокрылых машин, присвоив им обозначение YHC-1A . [ 5 ] Согласно приказу, YHC-1A мог перевозить максимум 20 военнослужащих. [ 2 ] Три прошли испытания в армии для получения инженерных и эксплуатационных данных. Однако многие армейские пользователи считали YHC-1A слишком тяжелым для штурмовой роли и слишком легким для более общей транспортной роли. [ 2 ] Соответственно, было принято решение закупить более тяжелый транспортный вертолет и в то же время модернизировать UH-1 «Хьюи», чтобы он мог служить необходимым тактическим транспортным средством для войск. YHC-1A будет улучшен и принят на вооружение морской пехоты как CH-46 Sea Knight в 1962 году. [ 6 ] В результате армия выдала Вертолу новый заказ на увеличенную модификацию V-107, известную под внутренним обозначением компании как Модель 114, которой было присвоено обозначение HC-1B. [ 7 ] 21 сентября 1961 года опытный образец Boeing Vertol YCH-1B совершил свой первый полет в режиме зависания. В 1962 году HC-1B был переименован в CH-47A в соответствии с системой обозначения самолетов Tri-Service США 1962 года ; его также назвали «Чинук» в честь народа чинук, обитавшего на северо-западе Тихого океана. [ 8 ]
CH-47 приводится в движение двумя турбовальными двигателями, установленными с каждой стороны заднего пилона вертолета и соединенными с несущими винтами приводными валами. Первоначальные модели были оснащены двигателями Lycoming T55 мощностью 2200 л.с. (1600 кВт) каждый. Несущие винты встречного вращения устраняют необходимость в вертикальном роторе противовращающего момента, позволяя использовать всю мощность для подъемной силы и тяги. Возможность регулировки подъемной силы любого ротора делает его менее чувствительным к изменениям центра тяжести, важного для подъема и опускания груза. При зависании над определенным местом двухвинтовой вертолет имеет повышенную устойчивость по сравнению с одновинтовым вертолетом при добавлении или удалении веса, например, когда солдаты спускаются с самолета или начинают подниматься по веревкам к самолету или когда сбрасывается другой груз. Если один двигатель выйдет из строя, второй сможет привести в движение оба ротора. [ 9 ] «Размер» «Чинуков» был напрямую связан с ростом количества «Хьюи» и настойчивыми требованиями армейских тактиков о том, чтобы первоначальные воздушные атаки строились вокруг этого отделения. Армия настаивала на использовании как «Хьюи», так и «Чинука», и этот акцент способствовал ускорению ее усилий по воздушной мобильности. [ 2 ]

С момента поступления вертолета на вооружение разрабатывались улучшенные и более мощные версии CH-47. Часто один и тот же планер модернизировался до более поздних стандартов, а иногда планеры были построены по более новой модернизации. Первым крупным конструкторским прорывом армии США стал ныне широко распространенный CH-47D, который поступил на вооружение в 1982 году. Усовершенствования по сравнению с CH-47C включали модернизированные двигатели, композитные лопасти несущего винта, перепроектированную кабину для снижения нагрузки на пилотов, улучшенные и дублированные электрические системы, усовершенствованная система управления полетом и улучшенная авионика. [ 10 ] Последним массовым поколением является CH-47F, который имеет несколько крупных обновлений, направленных на сокращение технического обслуживания, цифровое управление полетом и оснащен двумя двигателями Honeywell мощностью 4733 лошадиных силы (3529 кВт). [ 11 ]
Примером британской модернизированной версии является HC.4; первый HC.4 совершил первый полет 9 декабря 2010 года. [ 12 ]
Коммерческая модель Chinook, Boeing-Vertol Model 234, используется во всем мире для лесозаготовок, строительства, тушения лесных пожаров и поддержки операций по добыче нефти. В декабре 2006 года Columbia Helicopters Inc приобрела у Boeing сертификат типа модели 234. [ 13 ] Лицензию на производство Chinook также получили компании за пределами США, такие как Agusta (ныне AgustaWestland ) в Италии и Kawasaki в Японии. [ 14 ] [ 15 ]
The Army finally settled on the larger Chinook as its standard medium-transport helicopter, and by February 1966, 161 aircraft had been delivered to the Army. The 1st Cavalry Division had brought its organic Chinook battalion (three Chinook companies) when it arrived in 1965 and a separate aviation medium helicopter company, the 147th, had arrived in Vietnam on 29 November 1965.[16] This latter company was initially placed in direct support of the 1st Infantry Division. CH-47 crews quickly learned to mount an M60 machine gun in each of the forward doors. Sometimes they also installed an M2 machine gun to fire from the rear cargo door.[17]
The most spectacular mission in Vietnam for the Chinook was the placing of artillery batteries in perilous mountain positions inaccessible by any other means, and then keeping them resupplied with large quantities of ammunition.[2] The 1st Cavalry Division found that its CH-47s were limited to a 7,000-pound (3,200 kg) payload when operating in the mountains, but could carry an additional 1,000 pounds (450 kg) when operating near the coast.[2]

As with any new piece of equipment, the Chinook presented a major problem of "customer education". Commanders and crew chiefs had to be constantly alert that eager soldiers did not overload the temptingly large cargo compartment. It would be some time before troops would be experts at using sling loads.[2] The Chinook soon proved to be such an invaluable aircraft for artillery movement and heavy logistics that it was seldom used as an assault troop carrier. Some of the Chinook fleet was used for casualty evacuation, and due to the very heavy demand for the helicopters, they were usually overburdened with wounded.[18] Perhaps the most cost effective use of the Chinook was the recovery of other downed aircraft.[19]
At the war's peak the US Army had 21 Chinook companies in Vietnam.[citation needed] Pilots discovered the CH-47A's transmission system could not handle the two gas turbines running at full power, and high humidity and heat reduced the maximum lift by more than 20% in the low lands and 30% in mountain areas. More powerful, improved transmission and strengthened fuselages arrived in 1968 with the CH-47B, followed a few months later by the CH-47C. The CH-47s in Vietnam were generally armed with a single 0.308 in (7.62 mm) M60 machine gun on a pintle mount on either side of the aircraft for self-defense, with stops fitted to keep the gunners from firing into the rotor blades. Dust filters were also added to improve engine reliability. Of the nearly 750 Chinook helicopters in the U.S. and South Vietnam fleets, about 200 were lost in combat or wartime operational accidents.[20] The U.S. Army CH-47s supported the 1st Australian Task Force as required.

Four CH-47s were converted into ACH-47As by adding armor and improved engines. Its armament included two fixed forward firing M24A1 20 mm cannons, one turret with 40 mm automatic grenade launcher on the nose, five .50 in machine guns and two weapon pods on the sides that could carry either XM159B/XM159C 70 mm rocket launchers or 7.62 mm miniguns. They arrived in Vietnam in 1966, and they engaged in six months of operational testing at An Khê Army Airfield. They performed well in combat, but its high maintenance costs and demand for use in troop and cargo transport was stronger. Three ACH-47s were lost. One collided with a CH-47 while taxiing. Another had a retention pin shake loose on a 20 mm cannon and was brought down when its own gun fired through the forward rotor blades. The third was grounded by enemy fire and destroyed by enemy mortar rounds after the crew escaped.[21]
Imperial Iranian Air Force CH-47C in France before delivery in 1971
During the 1970s, the United States and Iran had a strong relationship, in which the Iranian armed forces began to use many American military aircraft, most notably the F-14 Tomcat, as part of a modernization program.[22] After an agreement signed between Boeing and Agusta, the Imperial Iranian Air Force purchased 20 Agusta-built CH-47Cs in 1971.[23] The Imperial Iranian Army Aviation purchased 70 CH-47Cs from Agusta between 1972 and 1976. In late 1978, Iran placed an order for an additional 50 helicopters with Elicotteri Meridionali, but that order was canceled immediately after the revolution;[24] 11 of them were delivered after multiple requests by Iran.[25]
In the 1978 Iranian Chinook shootdown, four Iranian CH-47Cs penetrated 15–20 km (9–12 mi) into Soviet airspace in the Turkmenistan Military District. They were intercepted by a MiG-23M which shot down one CH-47, killing eight crew members, and forced a second helicopter to land.[citation needed] Chinook helicopters were used in efforts by the Iranian against Kurdish rebels in 1979.[26]
During the Iran–Iraq War, Iran made heavy use of its US-bought equipment, and lost at least eight CH-47s during the 1980–1988 period, most notably during a clash on 15 July 1983, when an Iraqi Mirage F1 destroyed three Iranian Chinooks transporting troops to the front line, and on 25–26 February 1984, when Iraqi MiG-21 fighters shot down two examples.[27] On 22 March 1982, in Operation Fath ol-Mobin, a key operation of the war, Iranian Chinooks were landed behind Iraqi lines, deployed troops that silenced their artillery, and captured an Iraqi headquarters; the attack took the Iraqi forces by surprise.[28]
Despite the arms embargo in place upon Iran,[29][30] it has managed to keep its Chinook fleet operational.[31][32] Some of the Chinooks have been rebuilt by Panha. As of 2015, 20 to 45 Chinooks were operational in Iran.[33]
In 1976, the Libyan Air Force purchased 24 Italian-built CH-47C helicopters, 14 of which were transferred to the Libyan Army during the 1990s. The Libyan Air Force recruited Western pilots and technicians to operate the CH-47 fleet.[34] The Libyan Chinooks flew transport and support missions into Chad to supply Libyan ground forces operating there in the 1980s. Chinooks were occasionally used to transport Libyan special forces in assault missions in northern Chad.
In 2002, Libya sold 16 helicopters to the United Arab Emirates, as due to the Western embargo and lack of funds, maintaining them was difficult. The sale to UAE was a $939 million package that included equipment, parts, and training.[35] The number of CH-47s still in existence or operational during the ongoing Libyan civil wars that started in 2011 is not known.
The Chinook was used both by Argentina and the United Kingdom during the Falklands War in 1982.[36]
The Argentine Air Force and the Argentine Army each deployed two CH-47C helicopters, which were widely used in general transport duties. Of the Army's aircraft, one was destroyed on the ground by 30 mm cannon fire from an RAF GR3 Harrier, while the other was captured by the British and reused after the war.[37][38] Both Argentine Air Force helicopters returned to Argentina[39] and remained in service until 2002.

The CH-47D has seen wide use in Operation Enduring Freedom in Afghanistan and Operation Iraqi Freedom in Iraq. The Chinook is being used in air assault missions, inserting troops into fire bases, and later bringing food, water, and ammunition. It is also the casualty evacuation aircraft of choice in the British Armed Forces.[46] In combat theaters, it is typically escorted by attack helicopters such as the AH-64 Apache for protection.[47][48] Its lift capacity has been found of particular value in the mountainous terrain of Afghanistan, where high altitudes and temperatures limit the use of helicopters such as the UH-60 Black Hawk; reportedly, one Chinook can replace up to five UH-60s in the air assault transport role.[49]

The Chinook helicopters of several nations have participated in the Afghanistan War, including aircraft from Britain, Italy, the Netherlands, Spain, Canada, and Australia. Despite the age of the Chinook, it is still in heavy demand, in part due its proven versatility and ability to operate in demanding environments such as Afghanistan.[11][50]
In May 2011, an Australian Army CH-47D crashed during a resupply mission in Zabul Province, resulting in one fatality and five survivors. The helicopter was unable to be recovered and was destroyed in place.[51][52] To compensate for the loss, the ADF added two ex-U.S. Army CH-47Ds to the fleet which are expected to be in service until the introduction of the CH-47Fs in 2016.[53]
On 6 August 2011, a Chinook crashed near Kabul, killing all of the 38 aboard. The Chinook was reportedly shot down with a rocket-propelled grenade by the Taliban while attempting to assist a group of U.S. Navy SEALs. The 38 were members of NATO and allied forces, including 22 Naval Special Warfare operators, five U.S. Army Aviation soldiers, three U.S. Air Force special operations personnel, and seven Afghan National Army commandos. A civilian translator and a U.S. military working dog were also killed in the crash. The crash was the single deadliest during the entire Operation Enduring Freedom campaign. The previous biggest single-day loss for American forces in Afghanistan involved a Chinook that was shot down near Kabul in Kunar Province in June 2005 with all aboard killed, including a 16-member U.S. Special Operations team.[54][55]
Chinook helicopters participated in the 2021 Kabul airlift at the close of military operations in Afghanistan.[56]

The Chinook's ability to carry large, underslung loads has been of significant value in relief operations in the aftermath of natural disasters.[57] Numerous operators have chosen to deploy their Chinook fleets to support humanitarian efforts in stricken nations overseas. Following the 2004 Asian tsunami, the Republic of Singapore Air Force assisted in the relief operations in neighboring Indonesia using its Chinooks; similarly, after the 2005 Kashmir earthquake, the Royal Air Force dispatched several Chinooks to Northern Pakistan to assist in recovery efforts.[57]
In August 1992, six CH-47Ds were deployed from Fort Bragg in North Carolina to provide relief in the wake of Hurricane Andrew in what was one of the first major helicopter disaster relief operations on US soil.[58] Then President George H. W. Bush ordered the military to assist. The Chinooks arrived at Miami-Opa Locka Executive Airport, just outside of the disaster zone, one day after the President's order; early on, they performed a wide loop over Homestead and Florida City to publicly display their presence, helping to curtail lawlessness and looting.[59][60] The Chinooks initially flew twelve sorties per day out of Opa Locka, which expanded over time, often supporting distribution operations at Homestead AFB and Opa Locka, as well as delivering relief payloads via internal storage, not using sling loads, supplementing the two dozen distribution centers and trucks, proving essential as trucks could not reach the worst hit areas due to downed trees and power lines. They flew everyday for approximately three weeks, moving supplies and personnel around the disaster zone as well as carrying media and government officials, including then Congressman Bill Nelson. Ultimately, the Chinooks supplied 64 distribution sites throughout the zone and transported 1.2 million pounds of supplies before the urgent relief phase ended.[59]
Three of Japan's CH-47s were used to cool Reactors 3 and 4 of the Fukushima Nuclear power plant following the 9.0 earthquake in 2011; they were used to collect sea water from the nearby ocean and drop it over the affected areas.[61][62] In order to protect the crew from the heightened radiation levels present, a number of lead plates were attached to the floor of each Chinook;[63][64] even with such measures, pilots had to keep their distance from the reactors while also limiting flight times in the vicinity to a maximum of 45 minutes to avoid excessive radiation exposure.[65]

In April 2023, multiple Chinooks conducted the evacuation of the US Embassy in Khartoum, Sudan with Special Forces.[66] (see also Sudanese civil war (2023–present)) Chinooks have been deployed to Mali for MINUSMA.
Since the type's inception, the Chinook has carried out various secondary missions, including medical evacuation, disaster relief, search and rescue, aircraft recovery, fire fighting, and heavy construction assistance.[67]
In February 2020, the Indian Air Force started using Chinooks at theatres such as Ladakh and Siachen Glacier to assist Indian forces deployed at the Indian borders with China and Pakistan.[68] The Indian Space Research Organisation has also enlisted Indian Air Force Chinooks during the development of its Reusable Launch Vehicle Technology Demonstration Program, with Chinook helicopters air-dropping two test vehicles during the RLV-LEX-01 and RLV-LEX-02 conducted on April 2, 2023, and March 22, 2024, respectively.[69][70][71][72][73]

In February 2007, the Royal Netherlands Air Force became the first international customer of the CH-47F model, expanding their Chinook fleet to 17.[74] On 10 August 2009, Canada signed a contract for 15 extensively modified and upgraded CH-47Fs for the Canadian Forces, later delivered in 2013–2014 with the Canadian designation CH-147F.[11][75] On 15 December 2009, Britain announced its Future Helicopter Strategy, including the purchase of 24 new CH-47Fs to be delivered from 2012.[76] Australia ordered seven CH-47Fs in March 2010 to replace its six CH-47Ds between 2014 and 2017.[77][78] In September 2015, India approved purchase of 15 CH-47F Chinooks.[79] On 7 November 2016, Singapore announced that the CH-47F would replace its older Chinooks, which had been in service since 1994, enabling the Republic of Singapore Air Force to meet its requirements for various operations, including Search and Rescue (SAR), Aeromedical Evacuation (AME), and Humanitarian Assistance and Disaster Relief (HADR) operations.[80] The German government announced in June 2022 that the CH-47F Block 2 was selected as the winner of its heavy helicopter program to replace its Sikorsky CH-53G Sea Stallion fleet.[81][82] Germany is planning to buy 60 airframes to boost heavy lift capability.[83]
Spain had 17 CH-47 which it is planning to upgrade CH-47F standard.[84] By 2023, 13 CH-47D were upgraded to CH-47F, and additionally, 4 new build CH-47F were acquired.[85]
There have been many versions of the Chinook over the decades, there are variants that involve major upgrades such as engines and avionics, ones for certain tasks, such as Special Operation missions, and finally there are version for certain countries, such as the J model built by and for Japan.
The all-weather, medium-lift CH-47A Chinook was powered initially by Lycoming T55-L-5 engines rated at 2,200 horsepower (1,640 kW), which were replaced by the T55-L-7 rated at 2,650 hp (1,980 kW) engines or T55-L-7C engines rated at 2,850 hp (2,130 kW). The CH-47A had a maximum gross weight of 33,000 lb (15,000 kg), with a maximum payload about 10,000 lb (4,500 kg)[87] Delivery of the CH-47A Chinook to the U.S. Army began in August 1962. A total of 354 were built.[88]
XM34 armament system on ACH-47A "Birth Control" at Vung Tau Air Base
The ACH-47A was known as the Armed/Armored CH-47A (or A/ACH-47A) before being designated ACH-47A[89] as a U.S. Army Attack Cargo Helicopter, and unofficially referred to as Guns A Go-Go. Four CH-47A helicopters were converted to gunships by Boeing Vertol in late 1965. Three were assigned to the 53rd Aviation Detachment in South Vietnam for testing, with the remaining one retained in the U.S. for weapons testing. By 1966, the 53rd was redesignated the 1st Aviation Detachment (Provisional) and attached to the 228th Assault Support Helicopter Battalion of the 1st Cavalry Division (Airmobile). By 1968, only one gunship remained, and transport demands prevented more conversions. It was returned to the United States, and the program stopped.[90]
The ACH-47A carried five 7.62 × 51 mm M60D machine guns or .50-caliber (12.7 mm) M2HB heavy machine guns, provided by the XM32 and XM33 armament subsystems, two 20 mm M24A1 cannons, two 19-tube 2.75-inch (70 mm) Folding Fin Aerial Rocket launchers (XM159B/XM159) or sometimes two M18/M18A1 7.62 × 51 mm gun pods, and a single 40 mm M75 grenade launcher in the XM5/M5 armament subsystem (more commonly seen on the UH-1 series of helicopters). Rare newsreel footage shows one of the aircraft in action supporting the 8th Cavalry Regiment during an ambush at Bông Son, South Vietnam.[91] The surviving aircraft, Easy Money, has been restored and is on display at Redstone Arsenal, Alabama.[92][93]
The CH-47B was an interim upgrade while Boeing worked on a more substantially improved CH-47C. The CH-47B was powered by two Lycoming T55-L-7C 2,850 hp (2,130 kW) engines. It had a blunted rear rotor pylon, redesigned asymmetrical rotor blades, and strakes along the rear ramp and fuselage to improve flying characteristics. It could be equipped with two door-mounted M60D 7.62 mm NATOmachine guns on the M24 armament subsystem and a ramp-mounted M60D using the M41 armament subsystem. Some CH-47 "bombers" were equipped to drop tear gas or napalm from the rear cargo ramp onto Viet Cong bunkers. The CH-47B could be equipped with a hoist and cargo hook. The Chinook proved especially valuable in "Pipe Smoke" aircraft recovery missions. The "Hook" recovered about 12,000 aircraft valued at over $3.6 billion during the war; 108 were built.[citation needed]
The CH-47C featured more powerful engines and transmissions.[94] Three sub-versions were built, the first with Lycoming T55-L-7C engines delivering 2,850 shp (2,130 kW). The "Super C" had Lycoming T55-L-11 engines delivering 3,750 shp (2,800 kW), an upgraded maximum gross weight of 46,000 lb (21,000 kg), and pitch stability augmentation. The T55-L-11 engines were less reliable, as they had been hurriedly introduced to increase payload; thus, they were temporarily replaced by the more reliable Lycoming T55-L-7C. The Super C was distinguishable from the standard "C" by the uprated maximum gross weight.
The type was not approved by the FAA for civil aviation due to the nonredundant hydraulic flight boost system drive. The hydraulic system was redesigned for the succeeding CH-47D, allowing it to achieve certification as the Boeing Model 234. A total of 233 CH-47Cs were built. Canada bought eight CH-47Cs; deliveries of the type began in 1974. Receiving the Canadian designation "CH-147", these were fitted with a power hoist above the crew door; other changes included a flight engineer station in the rear cabin: operators referred to the configuration as the "Super C".[95] The CH-47C was used widely during the Vietnam War, eventually replacing the older Piasecki H-21 Shawnee in the combat assault support role.[citation needed]
The CH-47D shares the same airframe as earlier models, with more powerful engines. Early CH-47Ds were powered by two T55-L-712 engines. The most common engine is the later T55-GA-714A. With its triple-hook cargo system, the CH-47D can carry heavy payloads internally and up to 26,000 lb (12,000 kg) (such as 40-foot or 12-meter containers) externally. It was introduced into service in 1979. In air assault operations, it often serves as the principal mover of the 155 mm M198 howitzer, plus 30 rounds of ammunition, and an 11-man crew. The CH-47D has advanced avionics, including Global Positioning System. Nearly all US Army CH-47Ds were converted from previous A, B, and C models, a total of 472 being converted. The last U.S. Army CH-47D built was delivered to the U.S. Army Reserve, located at Fort Hood, Texas, in 2002.[96]
The Netherlands acquired all seven of the Canadian Forces' surviving CH-147Cs and upgraded them to CH-47D. Six more new CH-47Ds were delivered in 1995 for a total of 13. The Dutch CH-47Ds are improved over U.S. Army CH-47Ds, including a long nose for Bendix weather radar, a "glass cockpit", and improved T55-L-714 engines. As of 2011, the Netherlands planned upgrading 11 of them to the CH-47F standard at a later date.[97] As of 2011, Singapore has 18 CH-47D/SDs, which includes twelve "Super D" Chinooks, in service.[98] In 2008, Canada purchased 6 CH-47Ds from the U.S. for the Canadian Helicopter Force Afghanistan for $252 million.[99][100] With 1 CH-47D lost to an accident,[101] the remaining five were sold in 2011 after the end of Canada's Afghanistan mission and replaced with seven CH-147Fs.[102] The U.S. Army is surplusing many of its CH-47Ds for use in FAA restricted category.[citation needed]
The MH-47D was developed for special forces operations and has inflight refueling capability, a fast rope-rappelling system, and other upgrades. The MH-47D was used by U.S. Army 160th Special Operations Aviation Regiment. Twelve MH-47D helicopters were produced. Six were converted from CH-47As and six were converted from CH-47C models.[103]

The MH-47E has been used by U.S. Army Special Operations. Beginning with the E-model prototype manufactured in 1991, a total of 26 Special Operations Aircraft were produced. All aircraft were assigned to 2–160th SOAR(A) "Nightstalkers", home based at Fort Campbell, Kentucky. E models were converted from CH-47C airframes. The MH-47E has similar capabilities as the MH-47D, but with increased fuel capacity similar to the CH-47SD and terrain following/terrain avoidance radar.[104]
In 1995, the Royal Air Force ordered eight Chinook HC3s, effectively a lower cost MH-47E for special operations. They were delivered in 2001, but never became operational due to technical issues with their avionics fit, unique to the HC3. In 2008, work started to revert the HC3s to HC2 standard, to enable them to enter service.[105] As of 2017[update] they were upgraded to HC5 standard with a digital automated flight control system.[106]
In 2001, the CH-47F, an upgraded CH-47D, made its maiden flight. The first production model rolled out at Boeing's facility in Ridley Park, Pennsylvania, and first flew on 23 October 2006.[107] Upgrades included 4,868-shaft-horsepower (3,630 kW) Honeywell engines and airframe with better integrated construction for lower maintenance requirements.[108] The milled construction reduces vibration, as well as inspection and repair needs, and eliminates flexing points to increase service life.[109] The CH-47F can fly at speeds of over 175 mph (282 km/h) with a payload of more than 21,000 lb (9,500 kg).[110] New avionics include a Rockwell Collins Common Avionics Architecture System (CAAS) cockpit, and BAE Systems' Digital Advanced Flight Control System (DAFCS).[108]AgustaWestland assembles the CH-47F under license, known as the Chinook ICH-47F, for several customers.[111] Boeing delivered 48 CH-47Fs to the U.S. Army through August 2008; at that time Boeing announced a $4.8 billion (~$6.67 billion in 2023) contract with the Army for 191 Chinooks.[110]
A CH-47F Block 2 is being implemented as of 2020[update]. The Block 2 aims for a payload of 22,000 lb (10,000 kg) with 4,000 ft (1,200 m) and 95 °F (35 °C) high and hot hover performance, eventually increased up to 6,000 ft (1,800 m), to carry the Joint Light Tactical Vehicle; maximum takeoff weight would be raised to 54,000 lb (24,500 kg). It has 20% more powerful Honeywell T55-715 engines along with an active parallel actuator system (APAS) to enhance the digital advanced flight-control system, providing an exact torque split between the rotors for greater efficiency. A new fuel system combines the three fuel cells in each sponson into one larger fuel cell and eliminates intracell fuel transfer hardware, reducing weight by 90 kg (200 lb) and increasing fuel capacity. Electrical capacity is increased by three 60 kVA generators.[112][113] The Advanced Chinook Rotor Blades (ACRB), derived from the cancelled RAH-66 Comanche, were intended to improve lift performance in hot/high altitude conditions by 2,000 lb; however, the US Army ultimately decided against implementing the ACRB due to persistent vibration during testing, Boeing denied the assertion that the vibration was a safety risk and believed it could be solved with dampeners. In addition, the aft rotor blade was stalling when in a swept back position.[114]
The U.S. Army plans for a Block 3 upgrade after 2025, which could include a new 6,000 hp (4,500 kW) class engine with boosted power capacity of the transmission and drive train developed under the future affordable turbine engine (FATE) program and a lengthened fuselage. The Future Vertical Lift program plans to begin replacing the Army's rotorcraft fleet in the mid-2030s, initially focusing on medium-lift helicopters, thus the CH-47 is planned to be in service beyond 2060, over 100 years after the first entered service.[113]
The MH-47G Special Operations Aviation (SOA) version is similar to the MH-47E, but features more sophisticated avionics including a digital Common Avionics Architecture System (CAAS). The CAAS is a common glass cockpit used by helicopters such as MH-60K/Ls, CH-53E/Ks, and ARH-70As.[115] The MH-47G also incorporates all of the new sections of the CH-47F.[116]
An MH-47G from the 160th SOAR(A) conducts Maritime External Air Transportation System training with the U.S. Navy's Special Boat Team 12.
The modernization program improves MH-47D and MH-47E Special Operations Chinooks to the MH-47G design specs. A total of 25 MH-47E and 11 MH-47D aircraft were upgraded by the end of 2003.[citation needed] The final MH-47G was delivered to the U.S. Army Special Operations Command (USASOC) on 10 February 2011. Modernization of MH-47D/Es to the MH-47G standard is due by 2015.[117] On 1 September 2020, Boeing announced the delivery of the first MH-47G Block II to USASOC of an initial order of 24, with a stated ultimate requirement for 69. The MH-47G Block II includes all of the improvements from the CH-47F Block II, as well as inflight refueling capability, a comprehensive defensive aids suite and low-level/adverse weather piloting aids, such as forward-looking infrared and multi-mode/terrain-following radar. It is armed with two 7.62 mm M134 Miniguns and two M240 7.62 mm machine guns.[118]
The British MOD confirmed that while the U.S. does not export the model, the two countries were in discussion regarding the MH-47G as of 2017[update].[119] On 19 October 2018, the Defense Security Cooperation Agency notified Congress of a possible sale of 16 H-47 Chinooks (Extended Range) to the UK.[120]
The CH-47J is a medium-transport helicopter for the Japan Ground Self-Defense Force (JGSDF), and the Japan Air Self-Defense Force (JASDF).[121] The differences between the CH-47J and the CH-47D are the engine, rotor brake and avionics, for use for general transportation, SAR and disaster activity like U.S. forces.[122] The CH-47JA, introduced in 1993, is a long-range version of the CH-47J, fitted with an enlarged fuel tank, an AAQ-16 FLIR in a turret under the nose, and a partial glass cockpit.[122][123] Both versions are built under license in Japan by Kawasaki Heavy Industries, who produced 61 aircraft by April 2001.[124]
The Japan Defense Agency ordered 54 aircraft of which 39 were for the JGSDF and 15 were for the JASDF. Boeing supplied flyable aircraft, to which Kawasaki added full avionics, interior, and final paint.[125] The CH-47J model Chinook (N7425H) made its first flight in January 1986, and it was sent to Kawasaki in April.[126] Boeing began delivering five CH-47J kits in September 1985 for assembly at Kawasaki.[125]
On 9 November 2006, the HH-47, a new variant of the Chinook based on the MH-47G, was selected by the U.S. Air Force as the winner of the Combat Search and Rescue (CSAR-X) competition. Four development HH-47s were to be built, with the first of 141 production aircraft planned to enter service in 2012.[128] However, in February 2007 the contract award was protested and the GAO ordered the CSAR-X project to be re-bid.[129] The CSAR-X program was again terminated in 2009. In February 2010, the USAF announced plans to replace aging HH-60G helicopters, and deferred secondary combat search and rescue requirements calling for a larger helicopter.[130][131] In a long process the Air Force did not choose the larger Chinook, and the HH-60W entered service by 2020 to replace the older helicopters.[132]
For years the U.S. Navy has been operating different versions of the single-rotor CH-53 helicopter as its heavy-lift helicopter. CH-47s regularly conduct ship-based operations for U.S. Special Forces and other international operators.[133] Due to budget issues, technical problems and delays with CH-53K, the director of the Pentagon's cost assessment office directed US Navy to consider maritime versions of CH-47. Naval versions must be protected against the corrosive seaborne environment and be able to operate from aircraft carriers and amphibious ships.[134][135]
The Royal Air Force version of the CH-47C is designated Chinook HC1; its versions of the CH-47D are designated Chinook HC2 and HC2A. Additional types in RAF service include HC3,4,5,6, and 6A. (for further reading see Boeing Chinook (UK variants))
The export version of the CH-47C Chinook for the Italian Army was designated "CH-47C Plus".

работы над опытным БВ-347 В 1969 году начались . Это был СН-47А с удлиненным фюзеляжем, четырехлопастными винтами, съемными крыльями, установленными сверху фюзеляжа и другими изменениями. Первый полет он совершил 27 мая 1970 года и оценивался в течение нескольких лет. [ 138 ]
В 1973 году армия заключила контракт с компанией Boeing на разработку тяжелого вертолета (HLH), получившего обозначение XCH-62A . Это представлял собой увеличенный в размерах CH-47 без обычного корпуса, в конфигурации, аналогичной S-64 Skycrane ( CH-54 Tarhe ), но проект был отменен в 1975 году. Программа была перезапущена для испытательных полетов в 1980-е годы и снова не финансировался Конгрессом. [ 138 ] Увеличенная модель HLH была списана в конце 2005 года в Форт-Ракере , штат Алабама. [ 139 ]
26 декабря 1967 года самолет CH-47A с 33 военными пассажирами и экипажем разбился при посадке на авиабазе Фукат, провинция Биньдинь, Южный Вьетнам, в результате чего погибли 8 человек, находившихся на борту. [ 165 ]
6 мая 1969 года CH-47, на борту которого находились 83 человека, разбился в 3 милях (4,8 км) к юго-западу от базового лагеря Фок Винь в Южном Вьетнаме, в результате чего погибли 40 человек, находившихся на борту. [ 166 ]
18 августа 1971 года СН-47А, планер 66-19023, находился на вооружении 4-й авиационной роты 15-й авиационной группы. Вертолет перевозил 33 солдата взвода тяжелых минометов 2-го батальона 4-го пехотного полка 56 -й бригады полевой артиллерии из штаба батальона в Людвигсбурге в Графенвер для учений с боевой стрельбой. Усталостный отказ задней лопасти несущего винта привел к ее отделению, что привело к повреждению конструкции, что привело к крушению и взрыву, в результате которого погибли все 37 человек на борту, включая четырех членов экипажа. Мемориальная доска, установленная рядом с местом крушения в лесу недалеко от Пегница, была украдена в 2009 году. [ 167 ] [ 168 ]
28 ноября 1971 года самолет CH-47C с пятью членами экипажа и 28 солдатами 101-й воздушно-десантной дивизии, выполнявший рейс из Дананга на боевую базу Фубай в Южном Вьетнаме, врезался в возвышенность, в результате чего погибли все находившиеся на борту. [ 169 ]
18 октября 1974 года самолету CH-47C с серийным номером 74-22058 в США был присвоен номер 147001, но он никогда не имел маркировки канадских вооруженных сил. Самолет был потерян во время доставки в Канаду из-за отказа шестерни в главной коробке передач, вызванного необнаруженным повреждением металла в заготовке шестерни перед механической обработкой. Эта неисправность привела к выходу из строя приводного вала и потере синхронизации, что привело к гибели пяти человек. После длительных судебных разбирательств его заменили на 147009.

11 сентября 1982 года на авиашоу в Мангейме, Германия , разбился самолет армии США «Чинук» (серийный номер 74-22292) с парашютистами , в результате чего погибло 46 человек. Позже выяснилось, что авария была вызвана скоплением песка из молотой скорлупы грецкого ореха , используемого для чистки механизмов, который блокировал попадание смазки в подшипники трансмиссии. [ 170 ] [ 171 ] В результате аварии в конечном итоге было прекращено использование ореховой крошки в качестве чистящего средства.
2 июня 1994 года самолет CH-47 британских ВВС с 25 экспертами британской МИ-5, полиции и военной разведки, а также четырьмя членами экипажа, летевший из Северной Ирландии в Шотландию на конференцию, разбился на Малл-оф-Кинтайр.
30 октября 1997 года гражданский самолет BV234UT компании Columbia Helicopters (регистрация C-FHFH), занимавшийся лесозаготовками, разбился на острове Ванкувер , в Канаде в результате чего погибли оба пилота. Следствие установило, что вертолет потерял управление по рысканью из-за отказа компьютера управления полетом.
29 мая 2001 года солдат армии Республики Корея (Армия РК) CH-47D, устанавливавший скульптуру на Олимпийский мост в Сеуле , Южная Корея, не смог открыть скульптуру. Винты вертолета врезались в памятник; затем фюзеляж ударился и разломился на две части. Одна секция загорелась и рухнула на мост, а другая упала в реку. Все три члена экипажа, находившиеся на борту, погибли. [ 175 ] [ 176 ]
22 февраля 2002 года MH-47E спецназа армии США разбился в море на Филиппинах, в результате чего погибли все десять американских солдат, находившихся на борту. [ 177 ]
6 апреля 2005 года CH-47D армии США, известный как «Big Windy 25», разбился во время песчаной бури недалеко от Газни, Афганистан , в результате чего погибли все находившиеся на борту восемнадцать человек (пятнадцать солдат и три контрактника). [ 179 ] Пилоты были дезориентированы пыльной бурей. [ 180 ]
