Army Air Corps (United Kingdom)

The Army Air Corps (AAC) is a component of the British Army, first formed in 1942 during the Second World War by grouping the various airborne units of the British Army (which are no longer part of the AAC). Today, there are eight regiments (seven Regular Army and one Reserve) of the AAC as well as four Independent Flights and two Independent Squadrons deployed in support of British Army operations across the world. They are located in Britain, Brunei, Canada, and Germany. Some AAC squadrons provide the air assault elements of 16 Air Assault Brigade through Joint Helicopter Command.

First formation: 1942–1949Edit

The British Army first took to the sky during the 19th century with the use of observation balloons.[2] In 1911 the Air Battalion of the Royal Engineers was the first heavier-than-air British military aviation unit.[3] The following year, the battalion was expanded into the Military Wing of the Royal Flying Corps which saw action throughout most of the First World War until 1 April 1918, when it was merged with the Royal Naval Air Service to form the Royal Air Force.[4]

Between the wars, the army used RAF co-operation squadrons.[5]

At the beginning of the Second World War, Royal Artillery officers, with the assistance of RAF technicians, flew Auster observation aircraft under RAF-owned Air Observation Post (AOP) Squadrons. Twelve such squadrons were raised —three of which belonged to the RCAF— and each performed vital duties in a wide array of missions in many theatres.[6][7][8]

Early in the war, Winston Churchill announced the establishment of a new branch of army aviation, the Army Air Corps, formed in 1942. The corps initially comprised the Glider Pilot Regiment and the Parachute Battalions (subsequently the Parachute Regiment), Air Landing Regiments, and the Air Observation Post Squadrons. In March 1944, the SAS Regiment was added to the corps.[9]

One of their most successful exploits during the war was the capture of the Caen canal and Orne river bridges, which occurred on 6 June 1944, prior to the landings on Normandy. Once the three gliders landed, some roughly which incurred casualties, the pilots joined the glider-borne troops (Ox & Bucks Light Infantry) to act as infantry. The bridge was taken within ten minutes of the battle commencing and the men there withstood numerous attempts by the Germans to re-capture the location. They were soon reinforced and relieved by soldiers from Lord Lovat's 1 Special Service Brigade.[10]

The AAC was broken up in 1949, with the SAS returning to its independent status, while the Parachute Regiment and Glider Pilot Regiment came under the umbrella of the Glider Pilot and Parachute Corps.[9]

Second formation: 1957–presentEdit

In 1957 the Glider Pilot and Parachute Corps was split, with the Parachute Regiment becoming an independent formation, while the Glider Pilot Regiment was merged with the Air Observation Squadrons of the Royal Artillery into a new unit, the Army Air Corps.[11]

From 1970, nearly every army brigade had at least one Aviation Squadron that usually numbered twelve aircraft. The main rotor aircraft during the 1970s were the Westland Scout and Bell Sioux general purpose helicopters. The Sioux was replaced from 1973 by the Westland Gazelle used for Airborne reconnaissance;[12] initially unarmed, they were converted to carry 68mm SNEB rocket pods in 1982, during the Falklands War. The Scout was replaced from 1978 by the Westland Lynx, which was capable of carrying additional firepower in the form of door gunners.[13]

Basic rotary flying training was carried out on the Sioux in the 1970s, on the Gazelle in the 1980s and 1990s, and is currently conducted on the Eurocopter H145 through the Defence Helicopter Flying School.[14]

Fixed-wing types in AAC service have included the Auster AOP.6 and AOP.9 and DHC-2 Beaver AL.1 in observation and liaison roles. In 1989, the AAC commenced operating a number of Britten-Norman Islander aircraft for surveillance and light transport duties.[15] The corps operated the DHC-1 Chipmunk T.10 in a training role until its replacement by the Slingsby T67 Firefly in the 1990s. The Firefly was replaced by the Grob Tutor in 2010.[16]

Cold WarEdit

During the Cold War the majority of Army Air Corps units were based in Germany and part of the British Army of the Rhine. At the beginning of 1989 the Army Air Corps structure was as follows:[17][18][19][20]

War on TerrorEdit

A further boost in the Army Air Corps' capability came in the form of the Westland Apache AH.1 attack helicopter. In 2006, British Apaches deployed to Afghanistan as part of the NATO International Security Assistance Force. In 2004, Britten-Norman Defender fixed wing aircraft were purchased for Afghanistan and Iraq.[15]

Current structure and deploymentEdit


The Army Air Corps adopted their first Corps Mascot: Zephyr, a bald eagle, in October 2011[21]


The training of future Army Air Corps aircrew is delivered by the joint service UK Military Flying Training System. Elementary Flying Training is delivered at RAF Barkston Heath, alongside Royal Navy students.

Training Units, Middle Wallop

  • 7 (Training) Regiment AAC
    • 670 Squadron – Operational Training
    • 671 Squadron – 'Lynx/Gazelle/Bell 212'j (Future uncertain, given retirement of Gazelle and Lynx fleets)
    • 673 Squadron – Apache Conversion to type
  • Defence Elementary Flying Training School, RAF Barkston Heath | Prefect T1[22]
  • Defence Helicopter Flying School, RAF Shawbury | Squirrel HT.1
    • 660 Squadron


Army Air Corps personnel on parade, 2011

The strength of the Army Air Corps is about 2,000 Regular personnel, of which 500 are officers. However, the AAC draws an additional 2,600 personnel from the Royal Logistic Corps, the Royal Electrical and Mechanical Engineers and the Adjutant General Corps.[23] Therefore, total related Army Air Corps personnel is around 4,600.[24]


As of 2019, the AAC solely operates rotary-wing aircraft in the operational environment. The AAC uses the same designation system for aircraft as the Royal Air Force and the Fleet Air Arm. Fixed-wing training aircraft include the Grob Tutor for Army Flying Grading and the Grob Prefect (for Elementary Flying Training by No. 674 Squadron Army Air Corps).[25][26]

Today AAC aviators fly four types of helicopter, and within each type there are usually several marks/variants which carry out different roles. Pilots train with No. 1 Flying Training School[27] at RAF Shawbury. The School is a tri-Service organisation consisting of civilian and military instructors that take the student from basic flying through to more advanced flying such as instrument flying, navigation, formation flying and captaincy. In service aircraft include: the Bell 212HP AH1,[28] the Eurocopter AS365N3 Dauphin II,[29] the Airbus Helicopters H135 Juno,[26] the Westland Gazelle AH1,[30] the Westland Wildcat AH.1[31] and the AgustaWestland Apache AH1.[32]

Transfer of Fixed-Wing assets

In April 2019, the Army transferred the AAC's Islander and Defender aircraft operated by 651 Squadron from 5 Regiment to No. 1 Group Royal Air Force. The aircraft will be operated by RAF personnel, replacing Army personnel through attrition.[33]

Command and unitsEdit

The AAC regiments will be consolidated into the following structure:[34]

Aviation Reconnaissance Force

Wattisham Flying Station Headquarters (WFS HQ), formerly the Attack Helicopter Force (AHF) (Supporting 3rd (UK) Division, 16 Air Assault Brigade and Royal Marines) Wattisham | Apache AH.1[38]

Army Reserves[39]

    • 6 Regiment AAC
      • RHQ/HQ Squadron, Bury St. Edmunds
      • 675 Squadron, Taunton/Yeovil
      • 677 Squadron, Bury St. Edmunds
      • 678 Squadron, Milton Keynes/Luton
      • 679 Squadron, Portsmouth/Middle Wallop
      • Aviation Specialist Group, Middle Wallop

Joint Special Forces Aviation Wing

1 and 9 Regt AAC will merge under one headquarters (1 Regt AAC) and re-locate to RNAS Yeovilton to form a large regiment equipped with the new AgustaWestland Wildcat helicopter. The Regular component of Army Air Corps capability will consist of two regular aviation regiments equipped with Apache, one large regular aviation regiment equipped with Wildcat, and one regular manned aerial surveillance regiment,[40] although the Gazelle out-of-service date is currently 2018 and it has not yet been confirmed whether or how the capability will be replaced.[41] All five squadrons from 1 and 9 AAC will remain. Four squadrons will be the front line Lynx Wildcat squadrons, one (652 Squadron) will become the Wildcat Operational Conversion Squadron.[42]

There will be two frontline squadrons of Apache helicopters in both 3 and 4 Regiment AAC, with 3 Regiment also parenting the Apache OCU, 653 Squadron. One Regiment will be at high readiness at any one time. One of the squadrons will be attached to HMS Ocean and/or the new Queen Elizabeth-class aircraft carriers for expeditionary operations. Another will be attached to the lead armoured battlegroup.[43] However, under Army 2020 Refine, 3 Regiment AAC will be tasked to support the armoured infantry, and strike brigades of 3 (UK) Division and 4 Regiment AAC will support the army's 16 Air Assault Brigade and 3 Commando Brigade of the Royal Marines.[44]

5 Regiment may be disbanded following the future retirement of the Gazelle fleet operated by 665 Squadron and also as a consequence of the transfer in 2019 of the Defender and Islander operated by 651 Squadron to the RAF.[33]

Joint Special Forces Aviation WingEdit

Independent unitsEdit

No. 651 Squadron personnel part of No. 1 Group RAF based at JHC FS Aldergrove.[33][46]

Battle honoursEdit

The Army Air Corps is classed, in UK military parlance, as a "Combat Arm". It, therefore, carries its own guidon and is awarded battle honours. The honours awarded to the AAC are:
