[edit] Design and development
The Aérospatiale Gazelle originated in a French Army requirement for a lightweight utility helicopter. The design quickly attracted British interest, leading to a development and production share out agreement with British company Westland Helicopters (later AgustaWestland). The deal, signed in February 1967, allowed the production in Britain of 292 Gazelles and 48 Aérospatiale Pumas ordered by the British armed forces, in return Aérospatiale were given a work share in the manufacturing programme for the 40 Westland Lynx naval helicopters for the French Navy.
Though the general layout resembles that of the Alouette series, the Gazelle featured several important innovations. This was the first helicopter to carry a fenestron or fantail, which allows considerable noise reduction. Also, the rotor blades were made of composite materials, a feature now widely used in modern helicopters.
In service with the French Army Light Aviation, the ALAT, the Gazelle is used primarily as an anti-tank gunship (SA 342M) armed with HOT missiles. A light support version equipped with a 20 mm cannon is used (SA 341F) as well as anti-air variants carrying the Mistral air-to-air missile (Gazelle Celtic based on the SA 341F, Gazelle Mistral based on the SA 342M). The latest anti-tank and reconnaissance versions carry the Viviane thermal imagery system and so are called Gazelle Viviane. The Gazelle is being replaced in frontline duties by the Eurocopter Tiger but will continue to be used for light transport and liaison roles.
It also served with all branches of the British armed forces—the Royal Air Force, Royal Navy (including Royal Marines) and the British Army in a variety of roles. Four versions of the Gazelle were used by the British Forces. The SA.341D became the Gazelle HT.3 in RAF service, equipped as a helicopter pilot trainer (hence HT). The SA 341E was used by the RAF for communications duties and VIP transport as the Gazelle HCC.4. The SA 341C was purchased as the Gazelle HT.2 pilot trainer for the Royal Navy. The training variants have now been replaced by the Squirrel HT1. The SA 341B was equipped to a specification for the Army Air Corps as the Gazelle AH.1 (from Army Helicopter Mark 1). It was used as an Air Observation Post (AOP) for directing artillery fire, Airborne Forward Air Controller (ABFAC) directing ground-attack aircraft, casualty evacuation, liaison, and command and control, and communications relay.
The Gazelle flown by the British Army Air Corps has recently been enhanced with a Direct Voice Input (DVI) system developed by QinetiQ. It allows for voice control of avionics equipment using standard aircrew helmet microphones and intercom. Being speaker independent, the system does not need to be trained to recognize a specific user. This means high command recognition rates may be achieved whether or not the user has operated the system before. It gives aircrew the ability to control aircraft systems using voice commands and access information without removing their hands from the flight controls or their eyes from the outside world. [1]
Gazelles were also manufactured in Egypt by ABHCO and in Yugoslavia by SOKO.
[edit] Operational history
- France
- The French army deployed the Gazelle on many occasions, especially during interventions in Africa and peacekeeping operations. This includes Chad (1980s), the former Yugoslavia (1990s), Djibouti (1991-1992), Somalia (1993) and Cote d'Ivoire (2002-Present). During Operation Desert Storm, HOT-carrying Gazelles were used against Iraqi armour.
- Iraq
- Iraq received an important number of Gazelles and HOT missiles in the '70s and '80s. They were used intensively in the Iran-Iraq War. During the Gulf War they saw little use, because of allied air supremacy.
- Syria
- Syrian Gazelles were used during 1982 Lebanon War. They had some success against Israeli armour, but suffered heavy losses.
- United Kingdom
- The Gazelle was used in combat in the Falkland Islands, Kuwait, Iraq and Kosovo and with 8 Flight Army Air Corps in support of 22 Special Air Service Regiment. It was also used for air patrols in Northern Ireland. British Gazelles were only armed when used in the Falklands, where they were fitted with machine guns and rocket pods, but these were not used.
- Ex-Yugoslavia
- SA 341/342 Gazelle GAMA (Yugoslav version) was used by Republika Srpska Air Force and Republika Srpska Krajna Militia Air Force during the Yugoslav civil wars (1991-1995), and by the Yugoslav air force during the Kosovo war.
- Lebanon
- The Gazelle was used by the Lebanese Air Force against the Al Qaeda-inspired militants of Fatah al-Islam during the battle of Nahr el-Bared.
- Ireland
- The Irish Air Corps formerly operated two Gazelle helicopters as pilot training aircraft.
