Developed from Aérospatiale Alouette III

The Aérospatiale Gazelle is a five-seat light helicopter, powered by a single turbine engine. It was designed and manufactured in France by Sud Aviation (later Aérospatiale). It was also manufactured under licence by Westland Aircraft in the United Kingdom (as the Westland Gazelle), by SOKO in Yugoslavia and ABHCO in Egypt. The Gazelle has been used by several military forces around the world.

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. 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 was 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 (ALAT), the Gazelle is used primarily as an anti-tank gunship (SA 342M) armed with Euromissile HOT missiles. A light support version (SA 341F) equipped with a 20 mm cannon is used 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.

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), Cote d'Ivoire (2002-Present) and Afghanistan (2002-Present).
During Operation Desert Storm, HOT-carrying Gazelles were used against Iraqi armour. They were also used in 2011, operating from the assault ship Tonnerre, under NATO in Libya to support the Libyan rebels' uprising against pro-Muammar Gadhafi's troops.
The French Army has employed Gazelles in several operations in Africa (at least in Chad, Djibouti, Somalia, and the Cote d'Ivoire) but the details of some of these operations are hard to know. In April 2011 four Gazelle attack helicopters accompanied by two United Nations Mi-24 gunships fired rockets and misiles on rebel president Gbagbo compound defences, neutralizing heavy weapons until he agreed to surrender.

Iraq
Iraq received a number of Gazelles and HOT missiles in the 1970s and 1980s. They were used intensively in the Iran–Iraq War. During the Gulf War they saw little use, because of Allied air supremacy.
Syria
Syria purchased the first 18 SA.342 Gazelles in 1977, in response to Israeli Bell AH-1 Cobras. These Gazelles entered service with the 976 Attack Helicopter Squadron, equipped with AS.12 anti-tank guided missiles. Additional SA.342s were supplied, enabling the SyAAF to organize a full brigade of three squadrons, and one unit used for liaison and cooperation with police. France supplied HOT ATGMs with those helicopters, considered at that time one of the most advanced ATGMs. Each Gazelle could carry four HOT missiles, mounted on stubs behind the cockpit.
Syrian Gazelles were used during 1982 Lebanon War. The three units equipped with the type flew slightly over 100 combat sorties during four days of battles between the Syrians and Israelis, in June 1982. Syrian Army claimed they had large success against Israeli armour (77 kills, 30 Israeli tanks and 50 other vehicles), while suffering medium losses (five helicopters).[2] One was captured by Israeli forces, tested and now is displayed in IAF museum.
SyAAF helicopters and special “hunter-killer teams” of the Syrian Army developed simple but effective tactics to ambush and tie down Israeli mechanized formations in the local hilly terrain, roads, dozens of villages in southern Lebanon.
Kuwait
Kuwait said its Gazelles were used during the Iraqi invasion, destroying some Iraqi trucks or APCs. Several were captured and used by Iraqi Army.

Ecuador
The Gazelle, it was used by the Ecuadoran Army during the Cenepa war, as escort of helicopters and close air support.[3]
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. Three Gazelles were lost in action in 1982, two due to ground fire, and one shot down by a Sea Dart surface to air missile fired by HMS Cardiff. British Gazelles performed as scouts for other attack platforms in 1991 Gulf War. Royal Navy Gazelles from the Commando Helicopter Force (CHF) operated briefly in Afghanistan in 2002, as they proved unsuitable for operations in Afghanistan.

Yugoslavia
SA 341/342 Gazelle GAMA was used by the Republika Srpska Air Force during the Yugoslav civil wars (1991-1995), and by the Yugoslav air force during the Kosovo war.
Lebanon
Lebanon obtained 11 second hand ex-UAE Gazelles, ready to operate with HOT armament, but armed only with machine guns. France refused to provide Lebanon with HOT missiles for their Gazelles for fear they could reach Hizabulla. These Gazelles were used by the Lebanese Air Force against the Al Qaeda-inspired militants of Fatah al-Islam during the battle of Nahr el-Bared. In 2010 it was reported that France offered to arm Lebanon’s Gazelle helicopters with HOT anti-tank missiles, but seems unlikely to happen.
Morocco
24 SA342L Gazelle helicopters were bought, half of them armed with HOT missiles and the other half with 20mm guns. Some were used in Western Sahara to fight Polisario columns.
Ireland
The Irish Air Corps formerly operated one Gazelle helicopters as pilot training aircraft as of 2011.

Performance

Popular culture

Two Gazelles were modified to star as a high-tech attack/surveillance helicopter in the 1983 action-thriller film Blue Thunder, and in its short-lived television series spinoff.[13] A Gazelle was used as part of the futuristic semi-truck in the television series The Highwayman. A Gazelle was also seen in the British motoring TV show Top Gear.[citation needed]
