The Aérospatiale Alouette III (French pronunciation: [alwɛt], Lark) is a single-engine, light utility helicopter developed by Sud Aviation. It was manufactured by Aérospatiale of France, and under licence by Hindustan Aeronautics Limited in India as Hal Chetak and Industria Aeronautică Română in Romania.
The Alouette III is the successor to the Alouette II, being larger and having more seating.

The first version of the Alouette III, the SE 3160 prototype, first flew on 28 February 1959. The SA 316A (SE 3160) entered production in 1961 and remained in production until 1968, when it was replaced by the SA 316B. The last and 1437th Alouette III left the Marignane assembly lines in 1979, when the main production line in France was closed down. The last Alouette III from Aérospatiale was delivered in 1985.
Over 500 units were manufactured under licence in Romania, India and Switzerland. Hindustan Aeronautics Limited (HAL) obtained a licence to build Alouette IIIs as the HAL Chetak in India. Over 300 units were produced by HAL as it continued to independently update and indigenize the helicopter over the years, and a variant is still in production though in diminishing volumes. Versions of the Alouette III were also either licence-built or assembled by IAR in Romania (as the IAR 316), F+W Emmen in Switzerland, and by Fokker and Lichtwerk in the Netherlands.
Production numbers are as follows:
- France: 1,453
- India: 300+ (Still in service)
- Romania: 200+
- Switzerland: 60
The Argentine Naval Aviation purchased 14 helicopters. One SA316B was on board the ARA General Belgrano when she was sunk by the HMS Conqueror's torpedoes during the Falklands War with Great Britain in 1982 and a second one played an important role during the Invasion of South Georgia. On 2 December 2010, the last example was retired at a ceremony held at BAN Comandante Espora, Bahía Blanca.
From April 1964 to 1967, three machines were delivered from France for local assembly in Australia. These were used by the Royal Australian Air Force (RAAF) at the Woomera Rocket Range for light passenger transport and the recovery of missile parts after test launches at the Range.

The Chilean Navy ordered a batch of ten SA-319Bs in 1977. The aircraft were delivered by the middle of 1978 and made operational just before the peak of the Channel Beagle crisis with Argentina, making the first real organic maritime ship borne tactical helicopter operated by Chile's naval forces. They were equipped with a radar and armed with rockets, guns, depth charges and a single light anti-submarine torpedo. A sole SA-319B was damaged during the frantic training period in 1978, but it was placed in storage and repaired back to airworthy condition later. All ten Chilean Navy SA-319Bs were operational and in excellent conditions at the end of the eighties, when they were replaced by SA532 Super Puma helicopters, and were bought by civilian operators.
Eight machines were delivered to the Royal Danish Navy from 1962 to 1967. They were primarily tasked with SAR and reconnaissance in support of the navy's Arctic patrol ships. In 1982, they were replaced by the Westland Lynx
The Alouette III entered service with the French Armed forces in 1960. The French Army ordered 50 Alouette IIIs in June 1961.
In June 1960, an Alouette III carrying seven people made take-offs and landings on Mont Blanc in the French Alps at an altitude of 4,810 meters (15,780 feet), an unprecedented altitude for such activities by a helicopter. The same helicopter again demonstrated the type 's extraordinary performance in November 1960 by making take-offs and landings with a crew of two and a payload of 250 kg (551 lbs) in the Himalayas at an altitude of 6,004 meters (19,698 feet).
In June 2004, the Alouette III was retired from the French Air Force after 32 years of successful service, being replaced by the Eurocopter EC 355 Ecureuil 2.
The French Navy still uses the Alouette III for Search and Rescue and Logistics missions.
The Irish Air Corps operated Alouette IIIs between 1963 and 2007; for much of this period they were the only helicopters in the Corps. The first two were delivered in 1963, a third in 1964 and five further aircraft between 1972 and 1974. At Baldonnel Aerodrome on 21 September 2007, the Alouette III was retired from the Irish Air Corps. During 44 years of successful service, the Irish Alouette III fleet amassed over 77,000 flying hours. As well as routine military missions, the aircraft undertook some 1,717 search-and-rescue missions, saving 542 lives and flew a further 2,882 air ambulance flights. The oldest of the Alouettes, 195, is kept in 'rotors running' condition for the Air Corps Museum.
Hindustan Aeronautics Limited built over 300 units of the helicopter under licence as the HAL Chetak. They were primarily in service with the Indian Armed Forces in training, transport, CASEVAC (Casualty Evacuation), communications and liaison roles. The Chetak is being replaced by HAL Dhruv in the armed forces. An option to re-engine the HAL Chetak with the Turbomeca TM 333-2B engine for high-altitude operations in the Himalayas was considered, but not pursued.
In 1986, the Government constituted the Army's Aviation Corps and most Chetak operating in AOP Squadrons were transferred from the Air Force on 1 November 1986. The Air Force continues to fly armed Chetaks in the anti-tank role as well as for CASEVAC and general duties.
Pakistan purchased 35 Alouette III helicopters and used them in the Indo-Pakistani War of 1971, mainly for liaison and VIP-transport. Two Alouette IIIs of the Pakistan Air Force (PAF) were shot down during the war.
Portugal was the first country to use the Alouette III in combat. In 1963, during the Overseas Wars in Angola, Mozambique and Portuguese Guinea, Portugal began using Alouette IIIs in combat, mainly in air assault and medevac operations, where it proved its qualities.
Besides the basic transport version (code named canibal, plural canibais), Portugal used a special version of the Alouette III with a MG 151 20 mm autocannon mounted in the rear in order to fire from the left side door. This version was designated helicanhão (heli-cannon) and code named lobo mau (big bad wolf).
In the Overseas Wars, the Portuguese usually launched air assaults with groups of six or seven Alouette III: five or six canibais - each usually carrying five paratropers or commandos - and a lobo mau heli-cannon. The Portuguese practice was for the troops to jump from the canibais when the helicopters were hovering two-three meters above the ground - famous images of these disembarking troops became an iconic image of the war. The landing of the troops was covered by the lobo mau. While the troops performed the ground assault, the canibais moved away from the combat zone, while the lobo mau stayed to provide fire support, destroying enemy resistance and concentration points with the fire from its 20 mm autocannon. Once the ground combat had finished, the canibais returned; firstly to collect the wounded, then the rest of the troops.
At its peak, No. 7 Squadron, Rhodesian Air Force, operated 34 Allouette III, along with a smaller number of Allouette II, in the troop transport, casevac and battlefield support roles. They played a major part in the Rhodesian Forces' "Fire Force" doctrine, both deploying ground troops, acting as observation and command post and providing mobile fire support as gunships.
The Alouette III served for over 44 years and flew more than 346,000 hours in the South African Air Force (SAAF), particularly during counterstrike operations in Angola. The aircraft was officially withdrawn from SAAF service at AFB Swartkop near Pretoria in June, 2006.
In 1999, the Surinam Air Force retired and sold its two Alouette III helicopters from active service. They have been on duty since 1986 in this small South American country bought from Portugal. Three new HAL Chetak Indian version Alouette III's were delivered to the Suriname Air Force on 13 March 2015, while the pilots and technicians of the Surinam Air Force were under training in Bangalore, India for some time.  
In 2004, the Swiss Armed Forces announced the retirement of the Alouette III from front-line service by 2006 and entirely by 2010.
The Venezuelan Air Force retired its Alouette IIIs in the late 1990s.
