The Aérospatiale Gazelle (company designations SA 340, SA 341 and SA 342) is a five-seat helicopter developed and initially produced by the French aircraft company Sud Aviation, and later by Aérospatiale. It is the first helicopter to feature a fenestron tail instead of a conventional tail rotor, as well as being the first helicopter to be adapted for single-pilot operations under instrument flight rules.

The Gazelle was developed during the 1960s as a successor to the

composite rotor system, the latter having required considerable development time. On 7 April 1967, the Gazelle performed its maiden flight
.

The first operational Gazelles were introduced in 1971. Initially, manufacturing lines for the type were established in both France and Britain. Later on, it was also manufactured under license by SOKO in Yugoslavia and the Arab British Helicopter Company (ABHCO) in Egypt. Multiple armed variants, orientated towards roles such as anti-tank gunship (SA 342M), light support (SA 341F), and anti-air variants were promptly produced for various services of the French armed forces. The Gazelle was flown by all branches of the British armed forces—the Royal Air Force, Royal Navy (including in support of the Royal Marines) and the British Army in a variety of roles. The Gazelle has been procured and operated by a wide range of export customers. While it has been typically operated in a military capacity to perform light transport, scouting, and light attack missions, the Gazelle has also seen use with civil operators as well.

During its lengthy service life, the Gazelle has participated in numerous conflicts around the world, including by Syria during the 1982 Lebanon War, by Rwanda during the Rwandan Civil War in the 1990s, and by numerous participants on both sides of the 1991 Gulf War. By the twenty-first century, many operators were in the process of replacing the Gazelle with newer rotorcraft; in French service, the Gazelle has been supplanted as an attack helicopter by the larger and more modern Eurocopter Tiger, but remained active for some time in the scout helicopter role. Numerous operators have elected to upgrade their rotorcraft for continued service, the type still being in use with multiple countries as of 2024. Production ended in 1996.

Development

The SA 340 Gazelle prototype in 1967 with its original conventional tail rotor

In 1966, Sud Aviation began working on a light observation helicopter to replace its Alouette II with seating for five people.[1] The Gazelle originated in a French Army requirement for a lightweight observation helicopter intended to replace the Aérospatiale Alouette III; early on in the aircraft's development, the decision was taken to enlarge the helicopter to enable greater versatility and make it more attractive for the export market.[2]

Early on, the Gazelle attracted British interest, which resulted in a major joint development and production work share agreement between Sud Aviation and Westland. The deal, signed in February 1967, allowed the production in Britain of 292 Gazelles and 48 Sud Aviation SA 330 Puma medium transport helicopters ordered by the British armed forces; in return Sud Aviation was given a work share in the manufacturing programme for the 40 Westland Lynx naval helicopters for the French Navy.[3][4]

Additionally, Westland would have a 65% work share in the manufacturing, and be a joint partner to Sud Aviation on further refinements and upgrades to the Gazelle. Westland would produce a total of 262 Gazelles of various models, mainly for various branches of the British armed forces. Gazelles for the civil market were also produced.[3][4]

The first prototype SA 340 flew for the first time on 7 April 1967, it initially flew with a conventional tail rotor taken from the Alouette II. The tail was replaced in early 1968 with the distinctive fenestron tail on the second prototype.[1][5] Four SA 341 prototypes were flown, including one for British firm Westland Helicopters. On 6 August 1971, the first production Gazelle conducted its first flight.[5] On 13 May 1967, a Gazelle demonstrated its speed capabilities when two separate world speed records were broken on a closed course, achieving speeds of 307 km/h over 3 kilometres and 292 km/h over 100 kilometres.[6]

, but will continue to be used for light transport and liaison roles.

Four versions of the Gazelle were used by the British forces. The SA 341D was

Eurocopter Squirrel HT1.[8] The SA 341B was equipped to a specification for the Army Air Corps
as the 'Gazelle AH.1' (from "Army Helicopter Mark 1").

The Gazelle proved to be a commercial success, which led Aérospatiale, as Sud Aviation had become, to quickly develop and introduce the SA 342 Gazelle series, which was equipped with uprated powerplants. Licensed production of the type did not just take place in the UK, domestic manufacturing was also conducted by Egyptian firm

ground-attack aircraft, casualty evacuation, liaison, and communications relay missions.[9] According to David Oliver, 1,560 Gazelles had been produced in both France and Britain at the end of production.[10]

Design

Westland SA-341D Gazelle, 1975

The Aérospatiale Gazelle was originally developed as a replacement to the popular Alouette helicopter series; various aspects of the Gazelle are shared with the Alouette, including its mission types, loose dimensions, and operational equipment. The Gazelle featured several key innovations, being the first helicopter with a fenestron or fantail; this is a shrouded multi-blade anti-torque device housed in the vertical surface of the tail in place of a conventional tail rotor.[5] The fenestron, while requiring a small increase in power at slow speeds, has advantages such as being considerably less vulnerable to damage, safer for people in close proximity to the helicopter, and low power requirements at cruising speeds, and has been described as "far more suitable for high-speed flight".[11][12] The fenestron has been credited with helping the Gazelle to become the world's fastest helicopter in its class.[13]

The original main

autorotation.[16]

The Gazelle is capable of transporting up to five passengers and up to 1,320 pounds of cargo on the underside cargo hook, or alternatively up to 1,100 pounds of freight in 80 cubic feet of internal space in the rear of the cabin. Armed variants would carry up to four HOT (Haut subsonique Optiquement Téléguidé Tiré d'un Tube) wire-guided anti-tank missiles, or a forward firing 20mm cannon mounted to the fuselage sides with its ammunition supply placed in the cabin.[17] Various optional equipment can be installed upon the Gazelle, such as fittings for engine noise suppression, 53 gallon ferry tanks, a rescue winch capable of lifting up to 390 pounds, emergency flotation gear, particle filter, high landing skids, cabin heater, adjustable landing lights, and engine anti-icing systems.[18] While the Gazelle had been developed under a military-orientated design programme, following the type's entry to service increasing attention to the commercial market was paid as well.[19] The type was marketed to civil customers; notably, civilian operator Vought Helicopters at one point had a fleet of at least 70 Gazelles.[3][20] Civil-orientated Gazelles often included an external baggage access door mounted beneath the main cabin.[21]

Civil SA 341G Gazelle

The docile flying abilities of the Gazelle are such that it has been reported as being capable of comfortably flying without its main hydraulic system operation at speeds of up to 100 knots.

trimming system. Hydraulic servo boosters are present on all flight control circuits to mitigate control difficulties in the event of equipment failure.[20][22] The Gazelle was the first helicopter to be adapted for single-pilot operations under instrument flight rules. An advanced duplex autopilot system was developed by Honeywell in order to allow the pilot to not be overworked during solo flights; the Gazelle was chosen as the platform to develop this capability as it was one of the faster and more stable helicopters in service at that point and had a reputation for being easy to fly.[23]

The Gazelle was designed to be easy to maintain, all bearings were life-rated without need for continuous application of lubrication and most fluid reservoirs to be rapidly inspected.[22] The emphasis in the design stage of achieving minimal maintenance requirements contributed towards the helicopter's low running costs; many of the components were designed to have a service life in excess of 700 flying hours, and in some cases 1,200 flight hours, before requiring replacement.[24] Due to the performance of many of the Gazelle's subsystems, features pioneered upon the Gazelle such as the fenestron would appear upon later Aerospatiale designs.[14][25]

As the Gazelle continued to serve into the 21st century, several major modernisation and upgrade programs were undertaken, commonly adding new avionics to increase its capabilities.

Direct Voice Input (DVI) system for the Gazelle, the DVI system enables voice control over many aspects of the aircraft, lowering the demands placed upon the crew.[27] In September 2011, QinetiQ and Northrop Grumman proposed outfitting former British Gazelles with autonomous flight management systems derived from the Northrop Grumman MQ-8 Fire Scout, converting them into unmanned aerial vehicles (UAV)s to meet a Royal Navy requirement for an unmanned maritime aerial platform.[28]

Operational history

Map of military operators

China

During the 1980s, China acquired eight SA 342L combat helicopters; these were the first dedicated attack helicopters to be operated by the People's Liberation Army. The purchase of further aircraft, including licensed production of the aircraft in China, had been under consideration, but this initiative was apparently abandoned following the end of the Cold War. The small fleet was used to develop anti-armour warfare tactics, Gazelles have also been frequently used to simulate hostile forces during military training exercises.[29]

France

The French Army has deployed the Gazelle overseas in many large-scale operations, often in support of international military interventions; including in

First Gulf War.[32]

During the subsequent military action, known as

Operation Desert Storm, HOT-carrying Gazelles were employed by several nations' forces, including Kuwait's air force, against Iraqi military forces occupying neighbouring Kuwait.[33] During the coalition's offensive into Kuwait, French Gazelles adopted a tactic of strafing enemy tanks, vehicles, and bunkers in continuous waves at high speed.[34]

Gazelles have often been dispatched to support and protect UN international missions, such as the 1992 intervention in the

Tonnerre; strikes were launched into Libya against pro-Gadhafi military forces.[37]

Military interventions in African nations, particularly former French colonies, have often been supported by Gazelles in both reconnaissance and attack roles; nations involved in previous engagements include

Opération Serval in Mali, performing raids upon insurgent forces fighting government forces in the north of the country.[39][40]

In 2016 the Direction générale de l'armement announced that Gazelle helicopters of the French Army Aviation's 4th Special Forces Helicopter Regiment (4ème RHFS) could be equipped with the M134 Minigun.[41]

Iraq

During the Iran–Iraq War fought throughout most of the 1980s, a significant amount of French-built military equipment was purchased by Iraq, including a fleet of 40 HOT-armed Gazelles.[42] Iraq reportedly received roughly 100 Gazelle helicopters.[43] The Gazelle was commonly used in conjunction with Soviet-built Mil Mi-24 gunships, and were frequently used in counterattacks against Iranian forces.[44] By 2000, following significant equipment losses resulting from the 1991 Gulf War, Iraq reportedly had only 20 Gazelles left in its inventory.[45]

In 2003, US intelligence officials alleged that a French firm had continued to sell spare components for the Gazelle and other French-built aircraft to Iraq via a third-party trading company, despite an

embargo being in place.[46] Eurocopter, Aerospatiale's successor company, had denied playing any role, stating in 2008 that "no parts have been delivered to Iraq".[47] In April 2009, Iraq, as part of a larger military procurement initiative, bought six Gazelles from France for training purposes.[48]

Syria

Syrian Gazelles were used extensively during the 1982 Lebanon War. In the face of a major Israeli ground advance, repetitive harassment attacks were launched by the Gazelles, which were able to slow their advance.[49] According to author Roger Spiller, panic and a sense of vulnerability quickly spread amongst Israeli tank crews following the first of these Gazelle strikes on 8 June 1982; the range of the Gazelle's HOT missiles being a key factor in its effectiveness.[50] The effectiveness of the Syrian helicopter raids was reduced throughout the month of June as Syrian air defenses were progressively eroded and the Israeli Air Force took aerial supremacy over Eastern Lebanon, thus making operations by attack helicopters increasingly vulnerable. However, Gazelle strikes continued to be successfully performed up to the issuing of a ceasefire.[51]

The 1982 war served to highlight the importance and role of attack helicopters in future conflicts due to their performance on both sides of the conflict.[52] Following the end of the war, the Syrian Army would claim that significant damage had been delivered against Israeli forces, such as the destruction of 30 tanks and 50 other vehicles, against the loss of five helicopters.[53] Israel would claim a loss of seven tanks to the Gazelle strikes and the downing of 12 Syrian Gazelles.[51] Author Kenneth Michael Pollack described the role of Syria's Gazelle helicopters as being "psychologically effective against the Israelis but did little actual damage. Although they employed good Western-style 'pop-up' tactics, the Gazelles were not able to manage more than a few armor kills during the war".[54]

Following the end of the war, Syria increased the size of its attack helicopter fleet from 16 to 50 Gazelles, complemented by a further 50 heavier Mil Mi-24 gunships.[52] Gazelles were also used several times in Syria during its civil war, most recently being seen supporting troops in the Palmyra Offensive using unguided missiles and HOT ATGMs.[55]

Kuwait

During the 1991

Kuwait's armed forces, during the invasion of the nation by Iraq.[56] During the subsequent coalition offensive to dislodge Iraqi forces from Kuwait, several of the escaped Kuwaiti Gazelles launched attack missions into occupied Kuwait to destroy Iraqi tanks and other, military targets.[57]

Ecuador

The Gazelle was used by the Ecuadoran Army during the 1995

Cenepa war between Ecuador and neighboring Peru, performing missions such as close air support and escorting other helicopters.[58] In 2008, a minor diplomatic spat broke out between Colombia and Ecuador following a reportedly accidental incursion into Colombian airspace by an Ecuadoran Gazelle.[59]

United Kingdom

The Royal Navy's Gazelles entered service in December 1974 with 705 Naval Air Squadron, Culdrose, to provide all-through flying training in preparation for the Westland Lynx's service entry. A total of 23 Gazelles were ordered for Culdrose.[64] Army-owned AH.1s also entered service with 3 Commando Brigade Air Squadron (3 CBAS) of the Royal Marines and later, the Commando Helicopter Force (CHF) of the Fleet Air Arm, where they operated as utility and reconnaissance helicopters in support of the Royal Marines.[65] The 12 Gazelles for 3 CBAS had entered service in 1975,[66] by which time, there were 310 Gazelles on order for the British military.[67]

8 Flight Army Air Corps

The type was also frequently used to perform airborne patrols in

Provisional IRA during a ground skirmish.[70]

During the Falklands War, the Gazelle played a valuable role operating from the flight decks of Royal Navy ships. Under a rapidly performed crash programme specifically for the Falklands conflict, Gazelles were fitted with 68mm SNEB rocket pods and various other optional equipment such as armour plating, flotation gear and folding blade mechanisms.[71] Two Royal Marines Gazelles were shot down on the first day of the landings at San Carlos Water.[72] In a high-profile incident on 6 June 1982, an Army Air Corps Gazelle was mistaken for a low-flying Argentine Lockheed C-130 Hercules and was shot down by HMS Cardiff, a British Type 42 destroyer.[73][74]

The Gazelle also operated in reconnaissance and liaison roles during the

War in Afghanistan. In 2007, it was reported that, while many British helicopters had struggled with the conditions of the Afghan and Iraqi theatres, the Gazelle was the "best performing model" with roughly 80% being available for planned operations.[75]

Various branches of the British military have operated Gazelles in other theatres, such as during the 1991 Gulf War against Iraq and in the 1999 intervention in Kosovo.[76] In 2009, the Army Air Corps was the sole operator of the Gazelle with approximately 40 in service with a planned out of service date in 2012.[77] In October 2009, it was announced that the out of service date had been extended to support domestic commitments including to the Police Service of Northern Ireland (PSNI) until 2018 at which point the PSNI was to have their own assets.[78][79]

In July 2016, the Ministry of Defence announced that the Gazelle would remain in service until 2025 taking the Gazelle past its 50th anniversary in UK military service and making it the oldest helicopter in active UK inventory.[80] The Gazelle is operated by 29 (BATUS) Flight AAC in Canada supporting the Suffield training site, 665 Squadron AAC in Northern Ireland with aerial surveillance tasks and at the Army Aviation Centre by 7 (Training) Regiment AAC Conversion Flight and 667 (Development & Trials) Squadron AAC.[81][82] In 2018 and 2019, the Ministry of Defence awarded contracts to sustain the fleet until 2022 with the option of an extension in 2025.[83][84] In 2019, the Army Air Corps had a fleet of 32 Gazelles with 19 in service.[85]

It was announced in January 2022 that the rest of the British Army's Gazelles will be phased out by March 2024 to be replaced by Airbus Helicopters H135.[86]

It was further announced that the Gazelle would be retired from service on 31 October 2023. The Army Air Corps made a farewell flypast from Flying Station Aldergrove in Northern Ireland to Vector Aerospace International Ltd in Gosport, flying over various British Army and RAF bases, on 23 October.[87]

Lebanon

Between 1980 and 1981, the Lebanese Air Force received from France ten SA 342K/L and SA 341H Gazelles equipped for anti-tank and utility roles, respectively, to equip its newly raised 8th attack squadron at Beirut Air Base. Initially based at the latter location, in 1983 the squadron was relocated north of the Lebanese capital, with the Gazelles being dispersed in small improvised helipads around Jounieh and Adma for security reasons, where one of the helicopters may have been damaged in a failed takeoff.

In 1988, a Lebanese Air Force pilot, the Druze Lieutenant Majed Karameh, defected from Adma airfield and flew a SA 342K attack helicopter to the Druze-controlled Chouf District, where it was impounded by the Druze People's Liberation Army (PLA) militia upon landing and transported by a PLA MAZ-537G tank transporter to the Saïd el-Khateeb Barracks at Hammana in the Baabda District. This particular helicopter appears to have never been used in combat by the PLA (since they had no aviation component, and therefore lacked the technically proficient personnel to help fly and maintain the captured airframe), which ended up being simply placed on storage at Hammana under the custody of the Druze 11th Infantry Brigade for the remainder of the Civil War.[90][91]

Employed extensively in the gunship role by providing

Lebanese Forces militia who illegally sold them to Serbia in 1991.[93]

After the conflict, the Lebanese Air Force Command made consistent efforts to rebuild its attack helicopter squadron with the help of the United Arab Emirates and nine SA 342L Gazelles formerly in service with the United Arab Emirates Air Force were delivered in 2007.[94] Due to budgetary constraints, the majority of the Gazelles operated by the Lebanese Air Force have often been kept in storage outside of times of conflict.[94]

The Gazelles saw combat against the

Al Qaeda-inspired Fatah al-Islam militants during the 2007 Lebanon conflict.[95] Rocket-armed Gazelles were used to strike insurgent bunkers during the brief conflict.[94] In 2010, a French government official stated that France had offered to provide up to 100 HOT missiles to Lebanon for the Gazelle helicopters.[96] According to reports, France may also provide additional Gazelles to Lebanon.[94]

Morocco

In January 1981, France and Morocco entered into a $4 billion military procurement deal in which, amongst other vehicles and equipment, 24 Gazelle helicopters were to be delivered to Morocco.[97] The Royal Moroccan Air Force operated these Gazelles, which were equipped with a mix of anti-tank missiles and other ground attack munitions, and made frequent use of the aircraft during battles with Polisario insurgents in the western Sahara region.[98] The reconnaissance capabilities of the Gazelle were instrumental in finding and launching attacks upon insurgent camps due to their mobility.[99]

Rwanda

In 1990, following appeals from Rwandan President

guerrilla warfare.[101] In 1994, French forces dispatched as a part of Opération Turquoise, a United Nations-mandated intervention in the conflict, also operated a number of Gazelles in the theatre.[102]

Egypt

As part of a major international initiative formalised in 1975 to build up

Arab military industries, Egypt commenced widescale efforts to replace arms imports with domestic production to provide military equipment to the rest of the Middle East, other Arab partner nations included Saudi Arabia, the United Arab Emirates, and Qatar.[103] Both France and Britain would form large agreements with Egypt; in March 1978, the Arab British Helicopter Company (ABHCO) was formally established in a $595 million deal with Westland Helicopters, initially for the purpose of domestically assembly of British Westland Lynx helicopters.[104] An initial order for 42 Gazelles was placed in mid-1975.[105] In the 1980s, ABHCO performed the assembly of 100 Gazelles;[10] the British Arab Engine Company also produced engines for Egyptian-build Gazelles.[106]

Mozambique

In 2021, three Gazelle helicopters played a significant role in the Battle of Palma, providing air support at the behest of the Mozambique security forces battling the insurgents and evacuating civilians and contractors from the besieged town.
