The '''AgustaWestland Apache''' is a [[Licensed production|licence-built]] version of the [[Boeing AH-64 Apache|Boeing AH-64D Apache Longbow]] [[attack helicopter]] for the [[British Army]] [[Army Air Corps (United Kingdom)|Air Corps]]. The first eight helicopters were built by [[Boeing Integrated Defense Systems|Boeing]]; the remaining 59 were assembled by [[Westland Helicopters]] (later [[AgustaWestland]]) at [[Yeovil]], [[Somerset]] in England from Boeing-supplied kits. Changes from the AH-64D include [[Rolls-Royce Turbomeca]] [[Rolls-Royce Turbomeca RTM322|RTM322 engines]], a new electronic defensive aids suite and a folding blade mechanism allowing the British version to operate from ships. The helicopter was initially designated '''WAH-64''' by Westland Helicopters and was later [[British military aircraft designation systems|given the designation]] '''Apache AH Mk 1''' (also written as "Apache AH1") by the [[Ministry of Defence (UK)|Ministry of Defence]].

The Apache was a valued form of [[close air support]] in the conflict in [[Afghanistan]], being deployed to the region in 2006. Naval trials and temporary deployments at sea had proven the aircraft as an able platform to operate from the decks of ships, which was a unique application of the Apache amongst its operators. British Apaches also served in the NATO [[2011 military intervention in Libya]] operating from [[Royal Navy]] ships. 

The Apache AH1 was retired in 25 March 2024 and all models were remanufactured to the later [[Boeing AH-64 Apache#AH-64E|AH-64E]] version.<ref>{{Cite web |title=British Army retires Apache AH1 attack helicopters, declares AH-64Es 'operationally ready' |url= https://www.janes.com/osint-insights/defence-news/defence/british-army-retires-apache-ah1-attack-helicopters-declares-ah-64es-operationally-ready|access-date=2024-04-30 |website=Janes.com |language=en}}</ref>

==Development==
The requirement for a new attack helicopter was identified by the British government in the early 1990s. In 1993, invitations to bid were issued. Bids received included the [[Eurocopter Tiger]], a modernised [[Bell AH-1 SuperCobra]], the [[Boeing AH-64 Apache|AH-64 Apache]], the [[Boeing/Sikorsky RAH-66 Comanche]], and the [[Agusta A129 Mangusta]].<ref name= 'NYT 1995'>{{cite news |url= https://www.nytimes.com/1995/07/13/business/worldbusiness/13iht-chop.html?pagewanted=1 |title= U.K. Must Choose 1 of 3 Attack Copters: Pitched Battle Near Done |first= Erik |last= Ipsen |work= The New York Times |date= 13 July 1995 |access-date= 14 February 2017 |archive-date= 19 April 2015 |archive-url= https://web.archive.org/web/20150419190536/http://www.nytimes.com/1995/07/13/business/worldbusiness/13iht-chop.html?pagewanted=1 |url-status= live}}</ref> Both the Tiger, Commanche and upgraded Cobra variant required more development, and thus risk, while the Apache was combat proven, though its performance in the [[Gulf War|First Gulf War]] was criticised by competitors.<ref name= 'NYT 1995'/> Westland and the Apache was selected in July 1995, and a contract for 67 helicopters was signed in 1996.<ref name= 'Agusta 2'>AgustaWestland 2011, p. 2.</ref><ref>{{cite web |url= http://www.accessmylibrary.com/coms2/summary_0286-6339513_ITM |title= High Noon For Tiger And Apache |publisher= Interavia Business & Technology |first= Nick |last= Cook |date= 1 May 1995 |access-date= 3 May 2010 |archive-date= 19 July 2012 |archive-url= https://archive.today/20120719050302/http://www.accessmylibrary.com/coms2/summary_0286-6339513_ITM |url-status= live}}</ref>

When the requirement for the Apache had been formalised in the early 1990s, military doctrine assumed that a large conventional armoured assault from the [[Eastern Bloc]] was Britain's main threat.

The [[Australian Army]] purchased two retired AgustaWestland Apaches in 2024. The helicopters will be used as non-flying training aids ahead of the delivery of AH-64E Apaches to the Army.

Several deviations were made to the standard Apache design used by the US and those exported to other countries.

The Apache was operated by two regiments of the [[Army Air Corps (United Kingdom)|Army Air Corps]] (3 Regt AAC and 4 Regt AAC) as part of [[1st Aviation Brigade Combat Team (United Kingdom)|1st Aviation Brigade]]. The Apache was intended to operate in the armed reconnaissance and attack roles, similar to the US usage of Apaches during the 1991 Gulf War.
