The '''Boeing AH-64 Apache''' ({{IPAc-en|ə|ˈ|p|æ|tʃ|i}} {{respell|ə|PATCH|ee}}) is an American twin-[[turboshaft]] [[attack helicopter]] with a tailwheel-type [[landing gear]] and a tandem cockpit for a crew of two. Nose-mounted sensors help [[target acquisition|acquire targets]] and provide [[night vision device|night vision]]. It carries a [[30 mm caliber|{{convert|30|mm|in|2|abbr=on}}]] [[M230 chain gun]] under its forward fuselage and four [[hardpoint]]s on stub-wing pylons for armament and stores, typically [[AGM-114 Hellfire]] missiles and [[Hydra 70]] rocket pods. [[redundancy (engineering)|Redundant]] systems help it survive combat damage.

The Apache began as the ''Model 77'' developed by [[Hughes Helicopters]] for the [[United States Army]]'s [[Advanced Attack Helicopter]] program to replace the [[Bell AH-1 Cobra|AH-1 Cobra]]. The prototype YAH-64 first flew on 30 September 1975. The U.S. Army selected the YAH-64 over the [[Bell YAH-63]] in 1976, and later approved full production in 1982. After acquiring Hughes Helicopters in 1984, [[McDonnell Douglas]] continued AH-64 production and development. The helicopter was introduced to U.S. Army service in April 1986. The advanced AH-64D Apache Longbow was delivered to the Army in March 1997. Production has been continued by [[Boeing Defense, Space & Security]]. As of March 2024, over 5,000 Apaches have been delivered to the U.S. Army and 18 international partners and allies.

Primarily operated by the U.S. Army, the AH-64 has also become the primary attack helicopter of multiple nations, including [[Greece]], [[Japan]], [[Israel]], the [[Netherlands]], [[Singapore]], and the [[United Arab Emirates]]. It has been built under license in the [[United Kingdom]] as the [[AgustaWestland Apache]]. American AH-64s have served in conflicts in [[United States invasion of Panama|Panama]], the [[Gulf War|Persian Gulf]], [[Kosovo War|Kosovo]], [[War in Afghanistan (2001–14)|Afghanistan]], and [[Iraq War|Iraq]]. Israel uses the Apache to fight in [[Lebanon]] and the [[Gaza Strip]]. British and Dutch Apaches were deployed to wars in Afghanistan and Iraq in 2001.

[[File:Hughes experimental copter.jpg|thumb|right|An early [[Hughes Helicopters|Hughes]] YAH-64 prototype with T-tail]]

After the [[Lockheed AH-56 Cheyenne|AH-56 Cheyenne]] was cancelled in 1972 in favor of projects like the [[U.S. Air Force]] [[Fairchild Republic A-10 Thunderbolt II|A-10 Thunderbolt II]] and the [[United States Marine Corps|Marine Corps]] [[Hawker Siddeley Harrier|AV-8A Harrier]], the United States Army sought an aircraft to fill an anti-armor attack role that would still be under Army command.<ref>{{cite news |title=Army Cancels Helicopter Contract |newspaper= Victoria Advocate |date= 10 August 1972}}</ref><ref>{{cite news |url=https://news.google.co.uk/newspapers?id=j8kPAAAAIBAJ&sjid=No0DAAAAIBAJ&pg=5294,127450&dq=advanced+attack+helicopter&hl=en |title=Army Decides To Scrap Cheyenne Helicopter Gunship |newspaper=Boca Raton News |date=3 September 1972}}</ref> The 1948 [[Key West Agreement]] forbade the Army from owning combat fixed-wing aircraft. The Army wanted an aircraft better than the [[Bell AH-1 Cobra|AH-1 Cobra]] in firepower, performance, and range. It would have the maneuverability for terrain following [[nap-of-the-earth]] (NoE) flying.<ref name=Bishop_p5>Bishop 2005, pp. 5–6.</ref> To this end, the U.S. Army issued a Request For Proposals (RFP) for the Advanced Attack Helicopter (AAH) program on 15 November 1972.<ref name=Army_p10>OAVCSA 1973, p. 10.</ref><ref>{{cite news |url=https://www.nytimes.com/1972/11/16/archives/army-seeking-bids-on-new-helicopter.html |title=Army Seeking Bids on New Helicopter |work=[[The New York Times]] |date=16 November 1972}}</ref> As a sign of the importance of this project, in September 1973 the Army designated its five most important projects as the "Big Five", with the AAH included.<ref>{{cite web |url=https://news.google.co.uk/newspapers?id=H64hAAAAIBAJ&sjid=hpoFAAAAIBAJ&pg=1762,200656&dq=advanced+attack+helicopter&hl=en |title=New Army Tactic |website=Reading Eagle |date=11 September 1973}}</ref>

Proposals were submitted by [[Bell Helicopter|Bell]], [[Boeing Rotorcraft Systems|Boeing Vertol]]/[[Grumman]] team, [[Hughes Aircraft|Hughes]], [[Lockheed Corporation|Lockheed]], and [[Sikorsky Aircraft|Sikorsky]]. In July 1973, the U.S. Department of Defense selected finalists Bell and Hughes Aircraft's Toolco Aircraft Division (later [[Hughes Helicopters]]). This began the phase 1 of the competition.<ref name=Bishop_p7>Bishop 2005, p. 7.</ref> Each company built prototype helicopters and went through a flight test program. Hughes' ''Model 77/YAH-64A'' prototype first flew on 30 September 1975, while Bell's [[Bell YAH-63|Model 409/YAH-63A]] prototype first flew on 1 October 1975. After evaluating the test results, the Army selected Hughes' YAH-64A over Bell's YAH-63A in 1976. Reasons for selecting the YAH-64A included its more damage tolerant four-blade main rotor and the instability of the YAH-63's [[tricycle landing gear]] arrangement.<ref name=Richardson_Peacock_p8>Richardson and Peacock 1992, p. 8.</ref><ref name=Donald_p114>Donald 2004, p. 114.</ref>

[[File:YAH-64 1982 01759-1 cr.jpg|thumb|left|A YAH-64A prototype in 1982]]
The AH-64A then entered phase 2 of the AAH program under which three pre-production AH-64s would be built, additionally, the two YAH-64A flight prototypes and the ground test unit were upgraded to the same standard.<ref name=Richardson_Peacock_p8/> Weapons and sensor systems were integrated and tested during this time, including the laser-guided [[AGM-114 Hellfire]] missile.<ref name=Bishop_p8>Bishop 2005, p. 8.</ref> Development of the Hellfire missile had begun in 1974, originally known by the name of ''Helicopter Launched, Fire and Forget Missile'' ('Hellfire' being a shortened acronym),<ref>{{cite web |url=http://www.boeing.com/history/bna/hellfire.htm |title=AGM-114 Hellfire missile |publisher=Boeing |access-date=30 July 2011 |url-status=dead |archive-url=https://web.archive.org/web/20110914210609/http://www.boeing.com/history/bna/hellfire.htm |archive-date=14 September 2011}}</ref> for the purpose of arming helicopter platforms with an effective anti-tank missile.{{citation needed|date=February 2023}}

===Into production===
In 1981, three pre-production AH-64As were handed over to the U.S. Army for Operational Test II. The Army testing was successful, but afterward it was decided to upgrade to the more powerful [[General Electric T700|T700-GE-701]] version of engine, rated at {{convert|1690|shp|abbr=on|lk=on}}. The AH-64 was named the ''Apache'' in late 1981, after the [[Apache]] tribe, following the tradition of naming Army helicopters after Native American tribes. It was approved for full-scale production in 1982.<ref name="Bishop_p8-9">Bishop 2005, pp. 8–9.</ref> In 1983, the first production helicopter was rolled out at Hughes Helicopter's facility at [[Mesa, Arizona]]. Hughes Helicopters was purchased by [[McDonnell Douglas]] for $470 million in 1984 ({{Inflation|US|470000000|1984|fmt=eq|r=-6}}).<ref name=Donald_p119>Donald 2004, p. 119.</ref> The helicopter unit later became part of The Boeing Company with the merger of [[Boeing]] and McDonnell Douglas in August 1997.<ref name=Boe_MDC_merge>{{cite web |url=http://www.stltoday.com/stltoday/news/special/pd125.nsf/0/0EC17704770E83BF86256E04006C5943?OpenDocument |title=McDonnell-Boeing Merger |website=St. Louis Post-Dispatch |first=Cynthia |last=Wilson |author2=Dale Singer |date=13 January 2004}}{{dead link|date=August 2017|bot=medic}}{{cbignore|bot=medic}}</ref> In 1986, the incremental or flyaway cost for the AH-64A was $7M and the average unit cost was approximately $13.9M based on total costs.<ref name=Donald_p119/>

A 1985 Department of Defense engineering analysis by the inspector general's office reported that significant design deficiencies still needed to be addressed by the contractor. The Army project manager Col. [[William H. Forster]] published a list of 101 action items. In 1986, the four 22-foot-long main rotor blades, each made from steel and composite material glued together to maximize strength and minimize weight by the Composite Structures Division of Alcoa Composites, were added to the list. The steel-composite rotors could not meet the Army specification for a life of 1500 flight hours, and needed replacement after just 146 hours. After six changes to the design, the rotor blade life was extended to 1400 hours by early 1991.<ref>{{cite news |url=https://www.washingtonpost.com/archive/politics/1991/02/20/temperamental-helicopter-joins-battle/7070af42-9f1a-4e45-95e0-b0d0d20c3d50/ |title=Temperamental Helicopter Joins Battle |first=Charles R. |last=Babcock |date=20 February 1991 |newspaper=The Washington Post |access-date=14 October 2021}}</ref>

===Further development===
During the 1980s, McDonnell Douglas studied an AH-64B, featuring an updated cockpit, new [[fire control system]] and other upgrades. In 1988, funding was approved for a multi-stage upgrade program to improve sensor and weapon systems.<ref>{{cite news |title=Helicopter Contract Awarded |publisher=Prescott Courier |date=17 August 1988}}</ref> Technological advance led to the program's cancellation in favor of more ambitious changes. In August 1990, development of the AH-64D Apache Longbow was approved by the [[Defense Acquisition Board]]. The first AH-64D prototype flew on 15 April 1992.<ref name="Donald_p150-3">Donald 2004, pp. 150–153.</ref> Prototype testing ended in April 1995. During testing, six AH-64D helicopters were pitted against a bigger group of AH-64As. The results demonstrated the AH-64D to have a sevenfold increase in survivability and fourfold increase in lethality compared to the AH-64A.<ref>[http://military.discovery.com/tv-shows/great-planes/videos/great-planes-the-deadly-apache.htm "Great Planes: Apache Helicopter"] {{webarchive |url=https://web.archive.org/web/20130117140912/http://military.discovery.com/tv-shows/great-planes/videos/great-planes-the-deadly-apache.htm |date=17 January 2013}}.

The AH-64E is able to control [[unmanned aerial vehicle]]s (UAVs), used by the U.S. Army to perform aerial scouting missions previously performed by the [[OH-58 Kiowa]]. Apaches can request to take control of an [[RQ-7 Shadow]] or [[MQ-1C Grey Eagle]] from ground control stations to safely scout via datalink communications. There are four levels of UAV interoperability (LOI): LOI 1 indirectly receives payload data; LOI 2 receives payload data through direct communication; LOI 3 deploys the UAV's armaments; and LOI 4 takes over flight control. UAVs can search for enemies and, if equipped with a [[laser designator]], target them for the Apache or other friendly aircraft.<ref>[http://www.army.mil/article/125676/Apache_UAV_teaming_combines__best_capabilities_of_man__machine_/ "Apache-UAV teaming combines 'best capabilities of man, machine'"].

In 2014, the Army began implementing a plan to move all Apaches from the Army Reserve and National Guard to the active Army to serve as scout helicopters to replace the [[OH-58 Kiowa]]. Using the AH-64 to scout would be less expensive than Kiowa upgrades or purchasing a new scout helicopter. AH-64Es can control UAVs like the [[MQ-1C Grey Eagle]] to perform aerial scouting missions; a 2010 study found the teaming of Apaches and UAVs was the most cost-effective alternative to a new helicopter and would meet 80 percent of reconnaissance requirements, compared to 20 percent with existing OH-58s and 50 percent with upgraded OH-58s. National Guard units, who would lose their attack helicopters, criticized the proposal.<ref>[http://breakingdefense.com/2014/01/budgets-betrayal-national-guard-fights-to-keep-apache-gunships/ Budgets & 'Betrayal': National Guard Fights To Keep Apache Gunships] – Breakingdefense.com, 23 January 2014</ref><ref>Head, Elan.

IAF AH-64s occasionally saw use in the [[air-to-air missile|air-to-air]] role. The first operational air-to-air kill took place on 24 May 2001, when an IAF shot down a Lebanese civilian [[Cessna 152]] aircraft. Israeli and Lebanese officials presented differing versions: Lebanon said Israel first intercepted the aircraft over Lebanese airspace and its pilot, flying without his instructor, mistakenly entered Israeli airspace, while Israel says the aircraft was already in Israeli airspace when it was intercepted and repeatedly refused to answer or comply with [[air traffic control]] (ATC) warnings.<ref>{{cite news |url=https://edition.cnn.com/2001/WORLD/meast/05/24/israel.plane.02/index.html |title=Israel shoots down Lebanese civilian plane |publisher=CNN }}</ref><ref>{{cite news |title=Israel shoots down light aircraft |url=http://edition.cnn.com/2001/WORLD/meast/05/24/israel.plane/|agency=CNN|date=24 May 2001}}</ref> The second air-to-air kill occurred on 10 February 2018, after an Iranian [[unmanned aerial vehicle|UAV]] entered Israeli airspace from Syria, an AH-64 destroyed it with a missile.<ref>{{cite web |url=https://www.youtube.com/watch?v=E0Jt_Vy4Mj0 |archive-url=https://ghostarchive.org/varchive/youtube/20211211/E0Jt_Vy4Mj0| archive-date=2021-12-11 |url-status=live|title=Iranian UAV Intercepted by an Israeli Helicopter |publisher=Israel Defense Forces |date=10 February 2018}}{{cbignore}}</ref>

===AH-64A===
[[File:Hatzerim 270613 Apache.jpg|thumb|[[Israeli Air Force]] AH-64A ''Peten'']]

The AH-64A is the original production attack helicopter. The crew sit in tandem in an [[aircraft armor|armored]] compartment. It is powered by two GE T700 turboshaft engines. The A-model was equipped with the −701 engine version until 1990 when the engines were switched to the more powerful −701C version.<ref>Bishop 2005, p. 12.</ref>

U.S. Army AH-64As are being converted to AH-64Ds. The service's last AH-64A was taken out of service in July 2012 before conversion at Boeing's facility in Mesa, Arizona.<ref>{{cite web |last= Bledsoe |first= Sofia |title=Army 'retires' last A model Apache helicopter |url= http://www.dvidshub.net/news/91675/army-retires-last-model-apache-helicopter |publisher=Defense Video & Imagery Distribution System |access-date= 18 July 2012}}</ref> On 25 September 2012, Boeing received a $136.8M contract to remanufacture the last 16 AH-64As into the AH-64D Block II version and this was planned to be completed by December 2013.<ref>[http://www.defenseindustrydaily.com/115b-contract-to-remanufacture-129-apaches-to-ah64d-longbow-configuration-02972/ Boeing Remanufactures AH-64A Apaches to AH-64D Block II]. Defense industry daily.</ref>{{Update inline|date=September 2021|reason=were they?}}

===AH-64B===
In 1991, after Operation Desert Storm, the AH-64B was a proposed upgrade to 254 AH-64As. The upgrade would have included new rotor blades, a Global Positioning System (GPS), improved navigation systems and new radios. U.S. Congress approved $82M to begin the Apache B upgrade. The B program was canceled in 1992.<ref>Bishop 2005, p. 10.</ref> The radio, navigation, and GPS modifications were later installed on most AH-64As via other upgrades.

===AH-64C===
Additional funding from Congress in late 1991 resulted in a program to upgrade AH-64As to an AH-64B+ version. More funding changed the plan to upgrade to AH-64C, which would include all of the changes to be included in the AH-64D except for mast-mounted radar and newer −700C engine versions. However, the C designation was dropped after 1993.<ref name= Donald_p153>Donald 2004, p. 153.</ref> With AH-64As receiving the newer engine from 1990, the only difference between the AH-64C and the AH-64D was the radar, which could be moved from one aircraft to another; thus, the decision was made to simply designate both versions as AH-64D.<ref name=Donald_p153/>

===AH-64F===
In 2014, Boeing conceptualized an Apache upgrade prior to the introduction of the U.S. Army's anticipated attack version of the [[Future Vertical Lift]] (FVL) aircraft, forecast to replace the Apache by 2040. The conceptual ''AH-64F'' would have greater speed via a new 3,000 shp turboshaft engine from the [[Improved Turbine Engine Program]], retractable landing gear, stub wings to offload lift from the main rotor during cruise, and a tail rotor that can articulate 90 degrees to provide forward thrust.<ref>{{cite web |url=https://www.flightglobal.com/news/articles/boeing-proposes-high-speed-apache-heavier-chinook-400777/ |title=Boeing proposes high-speed Apache, heavier Chinook |first=Stephen |last=Trimble |date=26 June 2014 |website=FlightGlobal |access-date=9 February 2019}}</ref> In October 2016, the Army revealed they would not pursue another Apache upgrade to focus on funding FVL; the Army will continue buying the Apache through the 2020s until Boeing's production line ends in 2026, then FVL is slated to come online in 2030.<ref>{{cite web |url=https://www.flightglobal.com/news/articles/army-will-not-pursue-ah-64f-model-apache-430045/ |title=Army will not pursue AH-64F model Apache |first=Leigh |last=Giangreco |date=4 October 2016 |website=FlightGlobal |access-date=9 February 2019}}</ref>

===Piasecki Speed Apache===
In the late 1990s, Piasecki conceived a proposal for an Apache with a tail–mounted ducted pusher rotor to enhance speed. However, the Speed Apache was not proceeded with.<ref>[http://www.combatreform.org/TACTICALSTUDIESGROUP/piaseckivtdp.htm Piasecki Compound Helicopters]. combatreform.org {{verify source|date=July 2024}}</ref> This appears to be similar to the [[Piasecki X-49 SpeedHawk]].

===Compound Apache===
In October 2018, Boeing began testing the ''AH-64E Block 2 Compound'', a [[compound helicopter]] design which added a larger fixed wing and a pusher propeller to the Apache airframe to provide additional lift and thrust, respectively. In addition, the engine exhaust was redirected downwards.<ref>{{cite news |url=https://www.janes.com/article/84079/boeing-testing-high-speed-apache-concept |title=Boeing testing high-speed Apache concept |author=Host, Pat |date=26 October 2018 |work=Jane's International Defence Review |url-access=subscription}}</ref> Collectively, the modifications were anticipated to improve speed to {{convert|185|knot|abbr=on}}, range to {{convert|460|nmi|abbr=on}}, payload to {{convert|5900|lb|abbr=on}}, and fuel economy. A 30% scale model completed wind tunnel testing in January 2019. The Compound Apache has been pitched as an interim replacement for the Apache before its replacement under the [[Future Vertical Lift]] program.<ref>{{cite news |url=https://www.rotorandwing.com/2019/04/26/boeing-finished-six-wind-tunnel-tests-compound-apache-january-company-says/ |title=Boeing Finished Six Wind Tunnel Tests on Compound Apache in January, Company Says |author=Wolfe, Frank |date=26 April 2019 |work=Rotor & Wing International |access-date=15 October 2019 |archive-date=15 October 2019 |archive-url=https://web.archive.org/web/20191015192511/https://www.rotorandwing.com/2019/04/26/boeing-finished-six-wind-tunnel-tests-compound-apache-january-company-says/ |url-status=dead }}</ref>

[[File:U.S. Army AH-64 prepares to launch from USS Nassau Feb 2005.jpg|thumb|A U.S. Army AH-64A Apache aboard {{USS|Nassau|LHA-4|6}} during Joint Shipboard Weapons and Ordnance training]]

During the 1980s [[Navalised|naval versions]] of the AH-64A for the [[United States Marine Corps]] and [[United States Navy|Navy]] were examined.<ref name="Richardson_Peacock_p60-61">Richardson and Peacock 1992, pp. 60–61.</ref><ref name=Donald_p150>Donald 2004, p. 150.</ref> Multiple concepts were studied with altered landing gear arrangements, improved avionics and weapons.<ref name="Richardson_Peacock_p60-61" /> The USMC conducted a two-week evaluation of the Apache in September 1981, including shipboard operation tests. Funding for a naval version was not provided; the USMC continued to use the [[Bell AH-1 SuperCobra|AH-1]].<ref name=Donald_p170>Donald 2004, p. 170.</ref>

The [[Canadian Forces Maritime Command]] also examined naval Apaches.<ref>{{cite news |title=Local firms hope for spin-offs from big naval aircraft project |work= Montreal Gazette |first= Peggy |last=Curran |date= 6 August 1986}}</ref> In 2004, [[British Army]] AgustaWestland Apaches were deployed upon the [[Royal Navy]]'s {{HMS|Ocean|L12|6}}, a [[Landing Platform Helicopter]], for suitability testing; there was U.S. interest in the trials.<ref name="seatrials1">{{cite web |url= http://www.navynews.co.uk/articles/2004/0405/0004051101.asp |title= Apache Moves Closer To Front Line |website= Navy News |date= 11 May 2004 |archive-url= https://web.archive.org/web/20110611043406/http://www.navynews.co.uk/articles/2004/0405/0004051101.asp |archive-date= 11 June 2011 |url-status=dead}}</ref> During the [[2011 military intervention in Libya]], the British Army extensively used Apaches from HMS ''Ocean''.<ref name="Apaches fly from HMS Ocean">{{cite web |url=http://www.royalnavy.mod.uk/The-Fleet/Ships/Assault-Ships/HMS-Ocean/ |title=HMS Ocean |publisher=Royal Navy/MOD |url-status=dead |archive-url=https://web.archive.org/web/20120618015525/http://www.royalnavy.mod.uk/The-Fleet/Ships/Assault-Ships/HMS-Ocean |archive-date=18 June 2012}}</ref> In 2013, US AH-64Ds were tested on several U.S. Navy ships.<ref>{{cite web |url=http://www.armytimes.com/article/20130905/NEWS/309050004 |title=Army helicopters fly from Navy ships, test joint ops |date= 5 September 2013 |first= Meghann |last=Myers |website=Army Times}}</ref>

===Export Apaches===
Several models have been derived from the AH-64A, AH-64D and AH-64E for export. The British-built [[AgustaWestland Apache]] (assembled from kits purchased from Boeing) is based on the AH-64D Block I with several different systems, including more powerful engines, folding rotor blades, and other modifications for operation from Royal Navy vessels.

===Block modification===
While a major change in design or role will cause the type designator suffix to change, for example from AH-64D to AH-64E, the helicopters are also subject to block modification. Block modification is the combining of equipment changes into blocks of modification work orders, the modifications in the block (sometimes called a block package) are all done to the helicopter at the same time.<ref name="block">{{cite web |url= http://www.apd.army.mil/pdffiles/r750_10.pdf |title= Army Regulation 750-10 Army Modification Program |url-status=dead |archive-url= https://web.archive.org/web/20130220191234/http://www.apd.army.mil/pdffiles/r750_10.pdf |archive-date= 20 February 2013 |df= dmy-all}}</ref>

The AH-64 has had some modest success on the export market. It has been popular in the middle east, where its role the Gulf War established a bit of reputation. Its main user continues to be the U.S. Army, and the largest user in Europe will be Poland.
