Alouette III

From PlaneSpottingWorld, for aviation fans everywhere

The Aérospatiale Alouette III (Template:IPA-fr, Lark) is a single-engine, light utility helicopter developed by Sud Aviation and later manufactured by Aérospatiale of France. The Alouette III is the successor to the Alouette II, being larger and having more seating. Originally powered by a Turbomeca Artouste IIIB turboshaft engine, the Alouette III is recognised for its mountain rescue capabilities and adaptabilityTemplate:Citation needed.

Development

The first version of the Alouette III, the SE 3160 prototype, first flew on 28 February 1959. Production of the SA 316A (SE 3160) began in 1961 and remained in production until 1968, when it was replaced by the SA 316B.

The Alouette III entered in service with the French Armed forces in 1960. From April 1964-1967, three machines were delivered from France for local assembly in Australia, and were used by Royal Australian Air Force (RAAF) at the Woomera Rocket Range for light passenger transport and recovery of missile parts after test launches at the Range.

Served in Indo-Pakistani War of 1971 when 2 planes of the PAF were lost in the war,[1] and the Portuguese Colonial War, during 60's and 70's with large utilization in Angola, Mozambique and Guinea, where it proved its qualities.

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 was delivered in 1985. However close to 500 more were to be manufactured under license in Romania, India and Switzerland. HAL of India continues to licence-build Alouette IIIs as the Chetak. 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: 1453
  • India: 300+ (Still in production)
  • Romania: 230
  • Switzerland: 60

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. In the same year, the Swiss Armed Forces announced the retirement of the Alouette III, from the front line by 2006, and entirely by 2010. Venezuelan Air forces retired their Alouette IIIs in the late 90s.

At Baldonnel 21 September 2007 the Alouette III was retired from the Irish Air Corps. During 44 years of successful service, the 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 currently being kept in 'rotors running' condition for the Air Corps Museum.[1]

Combat History

Argentina

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 (Islas Malvinas) War with Great Britain in 1982 and a second one played an important role during the Invasion of South Georgia. The last one was deactivated on December 3, 2010 [2]

France

The French Army needed a fast, well-armed machine for the war in Algeria. So during this war ALAT (Aviation Légère de l'Armée de Terre) used Alouette IIIs armed with Nord AS.10 and AS.11 wire-guided antitank missiles. The missiles were first used against guerillas who had holed up in heavily fortified mountain caves. Alouette IIIs could carry four missiles each, often operating in mixed formations with gun-armed Alouette IIIs.

India

Alouette III was built under licence and named Chetak by Hindustan Aeronautics Limited. Primarily in service with the IAF in the training, light transport, casevac(Casualty Evacuation), communications and liaison roles.

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.

The HAL Chetak is scheduled to be replaced by HAL's Advanced Light Helicopter. An option remains to re-engine the HAL Chetak with the Turbomeca TM 333-2B engine.

In 2009, India sold one Chetak helicopter to Namibia.

Namibia

In 2009, India sold two of their Chetak and one Cheetah helicopters to Namibia, for a total price of $10 million.

Pakistan

Simultaneously with acquisition of Mirage IIIs Pakistan purchased 35 Alouette III helicopters and used them in the Indo-Pak War of 1971, mainly for liaison and VIP-transport. Two were shot down in the 1971 Pakistan-India war.

Portugal

Guinea Bissau

The war in Guinea Bissau began in earnest in August 1961. From 1967 the situation changed considerably, when the Organisation of African Unity (OAU), officially provided its full support to the PAIGC, de-facto recognising this organisation as an official representation of Guinea Bissau. The Portuguese reaction to these developments was an intensive campaign of building schools, hospitals, housing, and roads, in an effort to improve the living conditions of the local population. Until then, communications were almost non-existent in Guinea. To improve the means of communication, 12 SA.316B Alouette III helicopters were permanently deployed, in order to support the civilians. Several of these helicopters were equipped with 20mm cannons, carried in the rear cabin and fired over the side.

Angola

Portugal used their Alouettes against guerrillas in Africa. During the 60's and 70's Portugal used large numbers of helicopters in Angola, Mozambique and Guinea, where Alouettes proved its qualities for use in dusty and hot flying conditions. The versatile Alouette III bore the brunt of COIN operations in Africa: Wherever the troops were sent, the helicopters led or transported them, flew reconnaissance and liaison, CASEVAC/MEDEVAC and other missions. The Portuguese Air Force would be the first to use them with French 20mm cannons.

The Portuguese needed some time until they learned how to make best use of their Alouettes. They started regularly sitting five of six armed troops aboard, in addition to the crew of two, despite the fact that the Alouette III was built to carry only four passengers. This placed especially the gearbox of the helicopters under strain, causing quite some maintenance problems in return.

After some time the French technicians assigned to FAP instructed the Portuguese to be more careful, and the practice was changed so the number of troops usually transported was reduced. This was causing some problems especially if there were casualties to recover, but there was no way around. The lack of facilities for evacuation of casualties (CASEVAC), however, was one of the main reasons for the low morale among the Portuguese soldiers. The FAP personnel was also highly praised and most of the successes during the war in Angola were achieved either by elite units or the air force. However, the Portuguese pilots had no means to communicate with ground troops: even the most elementary equipment – like smoke-grenades for marking targets, and mirrors – was not available, and the troops were not trained to communicate with pilots.

Rhodesia and South Africa, both of which were concerned about their own future in the case of the Portuguese defeat gave military support. They initially limited their participation on shipments of arms and supplies. However, by 1968 South Africa begun providing SA.316B Alouette III helicopters with crews to the FAP, and finally several companies of South African Defence Forces (SADF) infantry were deployed in southern central Angola. There were reports that a some Rhodesian pilots were recruited to fly FAP helicopters, however Rhodesian pilots were considered too valuable by the RRAF/RhAF to be deployed in support of the Portuguese, while the SADF had pilots and helicopters operating out of “Centro Conjunto de Apoio Aéreo” (CCAA – Joint Air Support Centre), set up in Cuito Cuanavale, in 1968.

FAP deployed a large number of SA.316B Alouette IIIs in Angola, and used them for all possible purposes. All the helicopters of this type were operated by Esquadra 94 and were camouflaged in overall green colour. This camouflage would soon be quite worn out to different shades of olive green due to the sun, sand and rain. In some operations a piece of tarpauline with a large number 1, 2, 3, or 4 was applied on the lower window of the cockpit doors. Several Rhodesian and South African "advisers" supported the Portuguese COIN operations, but these never succeeded in goading the Portuguese into employing some effective Rhodesian combat tactics.

Rhodesia

The Alouette III was originally purchased by the Rhodesians pre UDI. Later a large number of Alouette IIIs were covertly obtained from various sources to increase the capability of No. 7 Squadron and also to replenish the squadron for various losses suffered both by accidents and while on combat missions.

In the 1970s South African Air Force (SAAF) Alouette III helicopters were attached to No. 7 Squadron, Rhodesian Air Force. The Alouette III was also the choice of the South African Air Force which meant that training facilities and expertise could be shared. The Portuguese Air Force had also purchased Alouette IIIs.

For Fireforce missions a gunship version of the Alouette III was fitted with a Matra MG 151/20 20 mm cannon. The 'K-Car', as it was known, was operated usually with a crew of three, (pilot, gunner and fireforce commander). The 'K-Car' was used as a mobile command post to allow the army commander of the heli-borne troops to direct their operations from the air above them.

Ammunition for the 20mm Cannon was carried in a special bin in the left hand baggage compartment and fed to the cannon via a feed tray through the rear bulkhead. The spent brass was collected in a compartment below the cabin floor. The ammunition bin was supposed to be able to carry 440 rounds of 20mm ammuninition, but typically, only 400-410 rounds were loaded. The gunner in the 'K-Car' was also a technician and therefore he was not only the gunner, but also responsible for all the maintenance of his aircraft.

A Rhodesian Alouette III, 'K-Car' had the distinction of shooting down a Botswana Defence Force Islander on 9 August 1979 with its 20mm cannon.

The standard troop carrying/utility version of the Alouette III in the Rhodesian Air Froce were called 'G-Cars'. They were used by No. 7 Squadron for the troop transport, light air/ground fire support, SAR, casualty evacuation (CASEVAC) and a variety of other roles.

Rhodesian practice was to operate the 'G-Car' with a gunner/technician and to mount twin Mk 2 .303 Brownings machine guns, with about 400 rounds per gun. As with the 'K-Car', not only did the technician fly in combat and operate the aircraft's weapons, he was also responsible for all the maintenance of the helicopter too.

In the troop carrying role, a "Stick" of four soldiers was the standard load for the RhAF Alouette III. The seating configuration was two in the rear of the cabin, beside the gunner/technician and behind the pilot, with the "Stick commander" in the centre and his MAG gunner beside him. The other two riflemen were in the front on the rear facing bench seat. Experience in combat led the Rhodesians to remove all but the pilot's door on the 'G-Car' and to reverse the front passengers to widen the available floorspace and gain flexibility. With the doors removed, it was easier for the soldiers to leave the helicopter quickly. Reversing the front seats opened up floor area and therefore more space for internal cargo was available. The standard Sud Aviation front seats in the 'G-Car' were replaced in the Rhodesian Air Force by a "home made" rear facing bench seat. While carrying troops, casualties on a stretcher could be carried laterally across the rear of the cabin, one on the floor and another stretcher on a rack above it.

In September 1974 Rhodesian Air Force Alouette IIIs were fitted with anti-STRELA shrouds on the engines, the tail pipe was turned up to deflect the hot exhaust gasses into the rotor downwash and they were given matt paint finishes. This was done to reduce the Infra Red signature of the helicopter and proved to be highly successful for the type.

Several Alouettes were brought down by fire from the ground, but considering the intensity of operations, losses were surprisingly low. This was probably due to the highly skilled pilots' tactics of using ultra low level flying and terrain to keep out of the line of enemy fire.

At one stage, 27 SAAF helicopters were deployed in Rhodesia. Within No. 7 Squadron, the SAAF Alouettes were designated as belonging to Alpha Flight.

South Africa

The Alouette III helicopter served for 44 years and flew more than 346.000 hours in the South African Air Force (SAAF).

SAAF received its first examples in 1962, delivered to the SAAF’s 17 Squadron. In all, 118 were delivered between 1962 and the late 1970s. The last eight were received from Rhodesia, possibly as replacements for SAAF helicopters lost during operations in that country. Used in the SAAF in many roles, the Alouette III primary role was qualifying helicopter pilots and flight engineers for the SAAF, its secondary roles of SAR and supporting internal security in South Africa. The Alouette saw service with almost all SAAF helicopter units at one time or another. It was also used extensively throughout the Bush War in Namibia, Angola and Rhodesia. In these countries was used mainly in search-and-rescue, reconnaissance roles, providing top-cover for the Pumas during troop deployments and extractions and close air-support with Koevoet and army units. The Aloutte proved its durability in the demanding African environment.

by 1968 SAAF began providing Alouette III helicopters with crews to the FAP. SAAF was also deeply involved in Rhodesia from 1975 to 1980, at least 20 to 30 Alouette III helicopters were based in Rhodesia at any one time, initially under the South African Police name.

The Alouette III configurations used operationally by the SAAF during the Bush War were:

  • The K-car Gunship: armed with a Ga1, MG151 or Mk V Hispano 20mm cannon with AP and HE rounds. The most prominent feature of the K-car was the specially developed Heat shield around the turbine which vented the exhaust gasses up towards the rotors. This minimised the heat signature of the helicopter making it difficult for the Russian SAMs to lock onto target.
  • The G-car: Transport version, armed with 7.62mm FN MAG for Fireforce type and COIN operations.

An Alouette III powerplant and dynamics system were used as the basis for an engineering and development capability demonstrator as a precursor to the Rooivalk programme. It was designated the Alpha XH-1, and it first flew in 1984 and is preserved at the SAAF Museum. this Missile Gunship was armed with two AS12 Missiles and laser designator.

The official withdrawal of Alouette III in SAAF took place on 30 June 2006 at Swartkop in Pretoria.[3]
