The Army Aviation Corps (AAC) is the youngest arm of the Indian Army, being formally designated on 1 November 1986. The Army Aviation Corps units are designated as Squadrons. Each squadron generally consists of two Flights. Reconnaissance (Recce) and Observation (R & O) flights might be part of squadrons or operate independently. The latter do not have a parent squadron and are designated by an (I) in their name.
The earliest use of aircraft by the army can be traced to the air observation posts (Air OP), where aeroplanes were used during the First World War to help artillery spotters (Forward Observation Officers) to locate and direct artillery fire to targets on the ground. This role was improved upon and further refined in the Second World War. The Army Aviation wing of the Royal Air Force was established in India in 1942. No. 656 Air OP Squadron (RAF), the first Air OP unit reached the Indian subcontinent in 1943 to assist the operations in the Burma campaign. Following the war, 659 Squadron of the Royal Air Force, which had played an important role as an air observation post unit and worked closely with Army units in artillery spotting and liaison was despatched to India. On 14 August 1947, No.659 (Air OP) Squadron was disbanded and partitioned between India and Pakistan. No.1 (Independent) Air OP Flight of the Royal Indian Air Force was formed the next day. The aircraft (Auster Mark IVs) and ground equipment were retrieved by Captains HS Butalia, Govind Singh and Man Singh from Lahore and moved to Amritsar, and finally to Jalandhar. The second unit, No.2 Air OP Flight was raised in October 1947 with five Auster Mark Vs. During these early years, officers were trained at School of Artillery, Deolali, and also at the Royal Air Force Central Flying School at Little Rissington in the United Kingdom. [3] [4] [5]
The Austers of No.1 (I) Air OP Flight deployed in Jammu and Kashmir were employed in reconnaissance, direction of artillery fire and casualty evacuation from exposed advanced landing grounds, which it performed gallantly. During the fourteen months of operations, the Austers flew from Jammu and Srinagar airfields and the advance landing grounds (ALGs) at Naoshera, Jhangar, Rajouri, Mendhar and Chhamb. [3]
No. 2 Air OP Flight took part in Operation Polo and was attached with the 1st Armoured Division in September 1948. Following the operations, they moved to Begumpet Airport. [3] [5]
No.3 Air OP Flight, which was raised in 1958 with the new Auster Mark IX aircraft took part in the capture of Goa during Operation Vijay in 1961. [3] [5]
In 1963, the then Army Chief General Jayanto Nath Chaudhuri took up the case for raising of a separate air wing for the army, which would increase the firepower and mobility of the army and would comprise light, medium and heavy as well as armed helicopters. [6]
No.1 (I) Air OP Flight saw action against regular armoured forces, supported by artillery and mechanised infantry during the Rann of Kutch operations in April 1965. The Austers of the unit acted in support of the 50 (Independent) Parachute Brigade and proved useful during the heavy artillery duels. The most noteworthy event was the use of Austers to direct fire of 71 Medium Regiment leading to the direct hits on an ammunition dump at Biar Bet in the Rann. Following the ceasefire, the Army understood the need for more adequate Air OP cover and the limitations of the ageing Austers. This problem was well understood by Brigadier FSB Mehta, the then Brigadier (Artillery) in the Western Command, who incidentally was the first Indian Artillery officer to wear the wings of the Air OP in 1944. He got on loan Pushpak light training aircraft from Flying Clubs to raise Nos. 6, 7 and 8 Flights, which were made available to the frontline Army Divisions on the Western Front. Though lacking in aircraft, both in numbers and quality, the Air OP pilots performed a commendable job during the war. [3]
Following the war, the Pushpaks were given back to the Flying Clubs. They were replaced with HAL HAOP-27 Krishaks, which was a larger version of the Pushpak and was primarily designed as an agricultural aircraft. [7] The aircraft continued to be operated by the Army, but training and maintenance of aircraft were the responsibility of the Indian Air Force. Since the air force would only accept ten Army pilots per year, training of adequate numbers of pilots for the Air OP was a problem. Hence, No. 660 Air OP Squadron which was located at Patiala with five flights under its command, was given this additional responsibility of training. [3]
The late 1960s saw an intense debate between the army and the air force. The army wanted to equip each division with at least one Air OP flight, which was not agreeable to the air force. The army also wanted the fixed wing aircraft to be replaced with the more manoeuvrable helicopters. This was finally agreed upon and the army pilots underwent training and conversion in 1968. The plans were to introduce HAL Chetaks (Aérospatiale Alouette III) for operations in the plains and the HAL Cheetah (Aérospatiale SA 315B Lama) for the mountains. Both these helicopters were manufactured by Hindustan Aeronautics Limited under license from Aérospatiale of France. The introduction of helicopters in the army led to its use in diverse roles in addition to Air OP – transport, casualty evacuation, communications, liaison, light utility and light attack roles. [3]
A better equipped Air OP under the Eastern Command took part in Operation Cactus Lily. In addition to its traditional role of directing artillery fire, it flew communication sorties along with photo and reconnaissance missions. No. 11 AOP Flight dropped numerous surrender leaflets and then was instrumental in guiding the Mil Mi-4 transport helicopters during the daring crossing of the Meghna River by 4 Corps. Major Menezes landed an Army HAL Krishak at Tejgaon Airport at Dhaka, the first Indian fixed wing aircraft to do so. [3] [5]
Meanwhile, in the western sector, the Air OP units took part in the following sectors [3] [5] -
Following the 1971 war, the Air OP retired all their fixed wing aircraft and moved on completely to helicopters. New squadrons and flights were raised. With an increasing number of pilots needing to be trained, and the Air Force finding that difficult, 659 Air OP Squadron took up the responsibility of training at that time. These helicopter pilots proved their mettle in the frigid high altitudes of Siachen Glacier, the world's highest battlefield, where they supported the troops, flying in supplies, flying out the injured and directing artillery fire; braving both the weather and enemy fire. [3] [8] [9] [10]
The proposals were first put forward to the Government in April 1968 for an independent Corps of Army Aviation, which would be part of an integrated command and control along with tanks, guns and infantry. These were renewed in February 1977. The Air Force raised concerns about duplication of aircraft, ground facilities and manpower. The efforts were renewed in 1981, when a Study Group continued to press for a formal decision. The Chief of Army Staff, General Krishnaswamy Sundarji made a compelling presentation to the then Prime Minister Rajiv Gandhi in November 1985. This finally bore fruit and an Army Aviation Cell was created at Army headquarters under then Brigadier Atma Singh. On 16 July 1986, the Government decided that the Army would have its own communication and utility helicopters, which would wholly man, maintain and control it. All the Air OP Squadrons and Flights would be transferred to the Army, but all attack helicopter units and medium and heavy-lift helicopters would remain with the Air Force. The attack helicopters would be placed under command and control of the Army. An Additional Directorate General of Army Aviation was sanctioned on 29 October 1986 and placed under the Director General Mechanised Forces. The Corps of Army Aviation thus came into being on 1 November 1986, with Brigadier (later Major General) Atma Singh as the first Additional Director General. The Chetak and Cheetah helicopters were transferred to the Army, but the Air Force continued to provide logistic and maintenance support till 31 October 1989. The nomenclature Air OP was changed to Reconnaissance and Observation (R&O). [3] [4]
During the Indian Peace Keeping Force’s deployment in Sri Lanka, Nos. 10, 26 and 31 R&O Flights supported 54 Infantry Division in the Jaffna peninsula. 664 R&O Squadron eventually moved to Trincomallee in December 1987. The last flight withdrew from the island in March 1990. [3] [5] Cheetahs mounted with two 7.62mm machine guns (called Ranjits) provided useful fire support to the field units. [11]
During Operation Vijay, the corps with its Cheetahs of Nos. 663 and 666 R&O Squadrons and a number of Independent Flights carried out 3100 air sorties of operational flying in support of the Army's 3rd Infantry and 8th Mountain Divisions. It directed intense artillery fire, which turned out to be a turning point in the war, helped induction of special forces and evacuating 900 casualties from temporary and makeshift helipads. For their role, 663 and 666 R&O Squadrons were given COAS unit citations. [12] [3]
In October 2001, the nomenclature of R&O Squadrons / Flights was changed to Army Aviation Squadrons (R&O) or Army Aviation Flights (R&O). The same year, the first squadron with HAL Dhruv utility helicopters was raised. (No.201 Army Aviation Squadron) [3]
The President of India Mr Ram Nath Kovind, who is also the Supreme Commander of the Armed Forces, presented colours to the Army Aviation Corps on 10 Oct 2019 in a ceremonial parade, which was held at Army Aviation Base, Nasik Road. [15]
In August 2021, all Unmanned Aerial Vehicles (UAVs) of the Indian Army, many of which were earlier with the Artillery, were moved to the Army Aviation Corps. This bought all aviation assets of the Army under one roof. [16]
Before independence, officers were sent to Britain for training in the No. 43 Operational Training Unit (OTU) at Larkhill. After July 1948, the training had shifted to No. 2 Elementary Flying Training School of the Indian Air Force at Jodhpur. The gunnery leg of the Air OP conversion was to be completed at Deolali. [5]
The Combat Army Aviation Training School (CATS) was established in Nashik Road on 1 September 2003. The training was previously conducted at the School of Artillery in Deolali. [17] A Cheetah helicopter simulator was installed at CATS to reduce training costs and pilot risk in 2006. The simulator exposes trainees to snow, rain, varied terrain, night flying, emergencies, and tactical manoeuvres. [18]
Army Aviation Corps pilots are drawn from other combat arms, including artillery officers. Officers passing out from the Indian Military Academy can join the corps directly, if they have cleared the Pilot Aptitude Battery Test (PABT). They have a two-year attachment with a fall back arm after getting commissioned. Officers may revert to their parent corps or fall back arm, if they are grounded for any reason.
The Army Aviation Corps perform combat search and rescue (CSAR), artillery lift, combat transportation, logistics relief, military prisoner transportation and medical evacuation (MEDEVAC) in wartime and during natural disasters. The director general of the Army Aviation Corps is Lieutenant General A.K. Suri. [19]
The Indian Air Force flies attack helicopters such as the Mil Mi-24/Mi-35 and HAL Rudra, which are under the operational control of the army. Helicopters such as the HAL Chetak, HAL Cheetah and HAL Dhruv provide logistical support for the Indian Army in remote and inaccessible areas.
The Corps of Army Aviation still consists of a large number of ageing aircraft like the Cheetah and Chetak, which need replacement by modern helicopters. The predominant role of the corps continues to remain reconnaissance and observation. The absence of medium and heavy lift helicopters, which continues to remain with the Air Force, results in a deficiency of the tactical lift capability in the operational scenario. The delay in acquiring true attack helicopter units, which are integral to battle is a major concern. Lack of fixed wing aircraft, when the Indian Navy, Indian Coast Guard and paramilitary forces have them affects functions like command and control, staff transport, logistics, casualty evacuation and communication. [6] [12] [20]
The Army Aviation Corps has several squadrons. In addition, there are several Reconnaissance and Observation (R&O) flights that operate independently and are not attached to any squadrons. The full list can be accessed here – List of squadrons and flights.
The Corps presently includes the following squadrons: [21] [22] [23]

In 2012, the army was evaluating helicopters from Kamov, Eurocopter and AgustaWestland for its light-helicopter contract for supplying troops stationed at high altitudes. The $750 million contract for the 197 helicopters intended to replace its 1970s Chetak and Cheetah helicopters for high-altitude surveillance and logistics. The successful bidder would provide 60 helicopters in operating condition; the remaining 137 aircraft would be produced by Hindustan Aeronautics Limited (HAL). The successful bidder was required to invest at least 30 percent of the contract in India. [57] In December 2014, the Kamov Ka-226T was selected as a light utility helicopter to replace the Chetak and Cheetah while the HAL Light Utility Helicopter was developed. Kamov would build a production plant in India, and 197 helicopters would be purchased under the Make in India program. [58] [59] Of these 135 are earmarked for the Indian Army. [60] However the deal was later dead by 2021. The Army was looking at the indigenous HAL Light Utility Helicopter and later placed order for it under limited series production.
Other planned acquisitions are:

HAL is currently involved in designing and manufacturing of fighter jets, helicopters, jet engine and marine gas turbine engine, avionics, software development, spares supply, overhauling and upgrading of Indian military aircraft.
The Indian Air Force (IAF) is the air arm of the Indian Armed Forces. Its primary mission is to secure Indian airspace and to conduct aerial warfare during armed conflicts. It was officially established on 8 October 1932 as an auxiliary air force of the British Empire which honoured India's aviation service during World War II with the prefix Royal. After India gained independence from United Kingdom in 1947, the name Royal Indian Air Force was kept and served in the name of the Dominion of India. With the transition to a republic in 1950, the prefix Royal was removed.
The Army Air Corps (AAC) is the aviation arm of the British Army, first formed in 1942 during the Second World War by grouping the various airborne units of the British Army. Today, there are eight regiments of the AAC, as well as two independent flights and two independent squadrons deployed in support of British Army operations around the world. Regiments and flights are located in the United Kingdom, Kenya, and Canada. Some AAC squadrons provide the air assault elements of 16 Air Assault Brigade, through Joint Helicopter Command.
The Aérospatiale Alouette III is a single-engine, light utility helicopter developed by French aircraft company Sud Aviation. During its production life, it proved to be a relatively popular rotorcraft; including multiple licensed manufacturers, more than 2,000 units were built.
An attack helicopter is an armed helicopter with the primary role of an attack aircraft, with the offensive capability of engaging ground targets such as enemy infantry, military vehicles and fortifications. Due to their heavy armament they are sometimes called helicopter gunships.
The HAL Dhruv is a utility helicopter designed and developed by Hindustan Aeronautics Limited (HAL) in November 1984. The helicopter first flew in 1992; its development was prolonged due to multiple factors including the Indian Army's requirement for design changes, budget restrictions, and sanctions placed on India following the 1998 Pokhran-II nuclear tests. The name comes from a Sanskrit origin word dhruv which means unshakeable or firm.
The Aérospatiale SA 315B Lama is a French single-engined helicopter. It combines the lighter Aérospatiale Alouette II airframe with Alouette III components and powerplant. The Lama possesses exceptional high altitude performance.

The HAL Prachand is an Indian multi-role light attack helicopter designed and manufactured by Hindustan Aeronautics Limited (HAL) under Project LCH. It has been ordered by the Indian Air Force (IAF) and the Indian Army. Its flight ceiling is the highest among all attack helicopters.
The Taylorcraft Auster was a British military liaison and observation aircraft produced by the Taylorcraft Aeroplanes (England) Limited company during the Second World War.
No. 663 Squadron was an air observation post (AOP) unit, manned with Polish Army personnel, which was officially formed in Italy on 14 August 1944. Numbers 651 to 663 Squadrons were air observation post units working closely with Army units in artillery spotting and liaison. A further three of these squadrons, 664–666, were manned with Canadian personnel. Their duties and squadron numbers were transferred to the Army with the formation of the Army Air Corps on 1 September 1957.
663 Squadron AAC is a flying unit of the British Army's Army Air Corps (AAC).
656 Squadron AAC is a squadron of the British Army's Army Air Corps. It was chosen as one of the AAC new AgustaWestland Apache squadrons and in April 2004 started its conversion to role. The first phase of this completed in October 2004. The squadron was the first operational Apache squadron in the Army Air Corps and was awarded fully operational status along with the remainder of 9 Regiment AAC in June 2005. It is under 4 Regiment AAC as of 2007.
The HAL Light Utility Helicopter (LUH) along with its derivative Light Observation Helicopter (LOH) was designed and developed by Rotary Wing Research and Design Center (RWR&DC) one of the R&D sections of Hindustan Aeronautics Limited (HAL) for civilian and military applications. These are intended to replace license-built versions of Aérospatiale SA 315B Lama (designated Cheetah) and Aérospatiale Alouette III (designated Chetak) in service with Indian Army and Indian Air Force.
The Indian Air Force has been undergoing a modernization program to replace and upgrade outdated equipment since the late 1990s to meet modern standards. For that reason, it has started procuring and developing aircraft, weapons, associated technologies, and infrastructures. Some of these programs date back to the late 1980s. The primary focus of current modernization and upgrades is to replace aircraft purchased from the Soviet Union that currently form the backbone of the Air Force.
An air observation post (AOP) is an aeroplane or helicopter used in the role of artillery spotter by the British Army and Commonwealth forces. In this role, either the pilot of the aircraft or another crew member acts as an observer watching for targets on the ground, and/or as a forward observation officer directing the fire, by radio, of artillery on the ground.
INS Hansa, is an Indian naval air station located near Dabolim in Goa, India. It is India's biggest naval airbase. The military air base has a civil enclave, that operates as Dabolim Airport.
