==Operational history==

===Vietnam War===
[[File:1st Cavalry troops deploy from CH-47, Operation Masher, February 1966.jpg|thumb|Soldiers depart a CH-47 during [[Operation Masher]] in 1966.]]

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 (United States)|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.<ref>{{cite news |url= http://select.nytimes.com/gst/abstract.html?res=F40D10FF3C5A157A93C3A81783D85F418685F9 |title= Chinook Copter to Vietnam |work= The New York Times |date= 11 August 1965 |access-date= 29 March 2010 |archive-url= https://web.archive.org/web/20121103000428/http://select.nytimes.com/gst/abstract.html?res=F40D10FF3C5A157A93C3A81783D85F418685F9 |archive-date= 3 November 2012 |url-status= live}}</ref> This latter company was initially placed in direct support of the [[1st Infantry Division (United States)|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 Browning|M2]] machine gun to fire from the rear cargo door.<ref>{{Cite web|url=https://www.historynet.com/arsenal-ch-47c-chinook-helicopter.htm|title = Arsenal|date = 21 April 2017}}</ref>

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.<ref name="Tolsonarmy"/> The 1st Cavalry Division found that its CH-47s were limited to a {{convert|7000|lb|adj=on}} payload when operating in the mountains, but could carry an additional {{convert|1000|lb}} when operating near the coast.<ref name="Tolsonarmy"/>

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.<ref name="Tolsonarmy"/> 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.<ref>{{cite journal |title= Hardships and Personal Strategies of Vietnam War Nurses |first= Elizabeth A. |last= Scannell-Desch |author2= Marion Anderson |journal= Western Journal of Nursing Research |volume= 22 |number= 5 |pages= 526–550 |year= 2000 |doi= 10.1177/01939450022044584 |pmid= 10943170|s2cid= 41787367}}</ref> Perhaps the most cost effective use of the Chinook was the recovery of other downed aircraft.<ref>{{cite book |url= https://books.google.com/books?id=lXZuAAAAMAAJ |title= Vietnam choppers: helicopters in battle 1950–75 |first= Simon |last= Dunstan |publisher=Osprey Publishing |year= 2003 |page= 81|isbn= 978-0-85045-572-4}}</ref>

At the war's peak the US Army had 21 Chinook companies in Vietnam.{{citation needed|date=November 2020}} 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&nbsp;in ([[7.62×51mm NATO|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.<ref>Anderton, David & Miller, Jay – Boeing Helicopters CH-47 Chinook.

Four CH-47s were converted into ACH-47As by adding armor and improved engines. Its armament included two fixed forward firing [[Hispano-Suiza HS.404|M24A1 20&nbsp;mm cannons]], one turret with 40&nbsp;mm automatic grenade launcher on the nose, five .50 in machine guns and two weapon pods on the sides that could carry either [[Fin-Folding Aerial Rocket#Common Mk 40 FFAR Launchers|XM159B/XM159C]] 70&nbsp;mm rocket launchers or 7.62&nbsp;mm miniguns. They arrived in Vietnam in 1966, and they engaged in six months of operational testing at [[Camp Radcliff|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&nbsp;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.<ref>{{Cite web|url=https://www.businessinsider.com/this-monster-aircraft-was-the-helicopter-version-of-the-ac-130-gunship-2015-9?r=US&IR=T|title = This monster aircraft was the helicopter version of the AC-130 gunship|website = [[Business Insider]]}}</ref>

===Iran===
During the 1970s, the U.S. and Iran had a strong relationship, in which the Iranian armed forces began to use many American military aircraft, most notably the [[Grumman F-14 Tomcat|F-14 Tomcat]], as part of a modernization program.<ref>{{cite news|url=https://news.google.com/newspapers?id=2r4bAAAAIBAJ&pg=4795,3807638&dq=f14+iran&hl=en |title=Oil pact with U.S. firm: Iran signs agreement |first=Murray |last=Marder |newspaper=Victoria Advocate |date=26 July 1973}}{{dead link|date=November 2016 |bot=InternetArchiveBot |fix-attempted=yes}}</ref> After an agreement signed between [[Boeing]] and [[Agusta]], the [[History of the Iranian Air Force|Imperial Iranian Air Force]] purchased 20 Agusta-built CH-47Cs in 1971.<ref>{{cite news |url= http://select.nytimes.com/gst/abstract.html?res=F00A13FF3455127B93C7AB178CD85F458785F9 |title= U.S., Britain Quietly Back Military Build-Up of Iran |first= Tad |last= Szulcs |work= The New York Times |date= 25 July 1971 |access-date= 5 April 2010 |archive-url= https://web.archive.org/web/20110605164657/http://select.nytimes.com/gst/abstract.html?res=F00A13FF3455127B93C7AB178CD85F458785F9 |archive-date= 5 June 2011 |url-status= live}}</ref> The [[Imperial Iranian Army Aviation]] purchased 70 CH-47Cs from Agusta between 1972 and 1976.

In the [[1978 Iranian Chinook shootdown]], four Iranian CH-47Cs penetrated {{convert|15|–|20|km|mi|abbr=on|0}} into Soviet airspace in the [[Turkmenistan]] Military District. They were intercepted by a [[Mikoyan-Gurevich MiG-23|MiG-23M]] which shot down one CH-47, killing eight crew members, and forced a second helicopter to land.{{citation needed|date=March 2023}} Chinook helicopters were used in efforts by the Iranian against Kurdish rebels in 1979.<ref>{{cite news |url= https://news.google.com/newspapers?id=zbMwAAAAIBAJ&pg=4025,4705243&dq=iran+orders+chinook&hl=en |title= Iranian troops smash four-day siege by Kurds |newspaper=Lakeland Ledger |date= 27 August 1979}}</ref>

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 [[Dassault Mirage F1|Mirage F1]] destroyed three Iranian Chinooks transporting troops to the front line, and on 25–26 February 1984, when Iraqi [[Mikoyan-Gurevich MiG-21|MiG-21 fighters]] shot down two examples.<ref>{{cite web|url=http://www.acig.info/CMS/index.php?option=com_content&task=view&id=37&Itemid=47|title=Iraqi Air-to-Air Victories since 1967|author=Sander Peeters|access-date=13 November 2014|archive-url=https://web.archive.org/web/20161219172206/http://www.acig.info/CMS/index.php?option=com_content&task=view&id=37&Itemid=47|archive-date=19 December 2016|url-status=dead}}</ref> 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.<ref name="Farrokh 03">{{cite book|last=Farrokh|first=Kaveh|title=Iran at War: 1500–1988|publisher=Osprey Publishing|location=Oxford|isbn=9781780962214|date=20 December 2011}}</ref>

===Libyan wars===
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.<ref>Crossette, Barbara [https://www.nytimes.com/1981/11/03/world/role-of-americans-in-libyan-warfare-confirmed-by-us.html ROLE OF AMERICANS IN LIBYAN WARFARE CONFIRMED BY U.S. Published: 3 November 1981] {{Webarchive|url=https://web.archive.org/web/20170109115016/http://www.nytimes.com/1981/11/03/world/role-of-americans-in-libyan-warfare-confirmed-by-us.html |date=9 January 2017}} ''[[The New York Times]]'' Retrieved 18 November 2016</ref> The Libyan Chinooks flew transport and support missions into Chad to supply Libyan ground forces operating there in the 1980s.

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.<ref name=boeing /><ref>{{cite news |url= https://www.telegraph.co.uk/news/newstopics/politics/defence/6816249/MoD-to-buy-22-new-Chinooks.html |title= MoD to buy 22 new Chinooks |work= The Daily Telegraph |date= 15 December 2009 |location= London |access-date= 4 April 2018 |archive-url= https://web.archive.org/web/20100223220251/http://www.telegraph.co.uk/news/newstopics/politics/defence/6816249/MoD-to-buy-22-new-Chinooks.html |archive-date= 23 February 2010 |url-status= dead}}</ref>

On 6 August 2011, a Chinook crashed near Kabul, killing all of the 38 aboard. The Chinook was reportedly [[2011 Afghanistan Boeing Chinook shootdown|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.<ref>[https://www.nytimes.com/2011/08/07/world/asia/07afghanistan.html?ref=global-home "Copter Downed by Taliban Fire; Elite U.S. Unit Among Dead"] {{Webarchive|url=https://web.archive.org/web/20170812102724/http://www.nytimes.com/2011/08/07/world/asia/07afghanistan.html?ref=global-home |date=12 August 2017}}.

===Disaster relief===
The Chinook's ability to carry large, underslung loads has been of significant value in relief operations in the aftermath of [[natural disaster]]s.<ref name="Abraham disaster">Abraham, Suresh. [http://www.shpmedia.com/images/ADJ%2009%20TRANSPORT%20HELICOPTERS.pdf "Tactical Transport Helicopters in Humanitarian Relief Operations."] {{Webarchive|url=https://web.archive.org/web/20140219035143/http://www.shpmedia.com/images/ADJ%2009%20TRANSPORT%20HELICOPTERS.pdf |date=19 February 2014}} ''ADJ'', April 2009.</ref> Numerous operators have chosen to deploy their Chinook fleets to support humanitarian efforts in stricken nations overseas. Following the [[2004 Indian Ocean earthquake and tsunami|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.<ref name="Abraham disaster"/>

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.<ref>{{cite journal |url=https://www.nytimes.com/1992/08/28/us/hurricane-andrew-bush-sending-army-to-florida-amid-criticism-of-relief-effort.html |title=HURRICANE ANDREW; BUSH SENDING ARMY TO FLORIDA AMID CRITICISM OF RELIEF EFFORT |author=Edmund L. Andrews |journal=The New York Times|date=28 August 1992}}</ref> 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.<ref name="Research Paper 1993">Research Paper: Disaster Relief, World Vision and the Hurricane Andrew Relief Project.

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.<ref name="Research Paper 1993"/>
