The **Dassault Rafale** is a French twin-engine, canard delta wing, multirole fighter aircraft designed and built by Dassault Aviation. Equipped with a wide range of weapons, the Rafale is intended to perform air supremacy, interdiction, aerial reconnaissance, and nuclear strike missions.

In the late 1970s, the French Air Force and Navy were seeking to replace and consolidate their current fleets of aircraft. In order to reduce development costs and boost prospective sales, France entered into an arrangement with four other European nations to produce an agile multi-purpose fighter. Subsequent disagreements over workshare and differing requirements led to France's pursuit of its own development program. Dassault built a technology demonstrator which first flew in July 1986 as part of an eight-year flight-test programme, paving the way for the go-ahead of the project. The Rafale is distinct from other European fighters of its era in that it is almost entirely built by one country, involving most of France's major defence contractors, such as Dassault, Thales and Safran.

Many of the aircraft's avionics and features, such as direct voice input, the RBE2 AA active electronically scanned array radar and the Optronique secteur frontal infra-red search and track sensor, were domestically developed and produced for the Rafale programme. Originally scheduled to enter service in 1996, the Rafale suffered significant delays due to post-Cold War budget cuts and changes in priorities. The aircraft is available in three variants: Rafale C single-seat land-based version, Rafale B twin-seat land-based version, and Rafale M single-seat carrier-based version.

## Development

### Origins

In the mid-1970s, both the French Air Force (Armée de l'Air) and Navy (Marine nationale) had requirements for a new generation of fighters to replace those in or about to enter service. Because their requirements were similar, and to reduce cost, both departments issued a common request for proposal. In 1975, the French Ministry of Aviation initiated studies for a new aircraft to complement the upcoming and smaller Dassault Mirage 2000, with each aircraft optimised for differing roles.

In 1979, the French company Dassault joined the MBB/BAe "European Collaborative Fighter" (ECA) project which was renamed the "European Combat Aircraft". The French company contributed the aerodynamic layout of a prospective twin-engine, single-seat fighter; however, the project collapsed in 1981 due to differing operational requirements of each partner country. In 1983, the "Future European Fighter Aircraft" (FEFA) programme was initiated, bringing together Italy, Spain, West Germany, France and the United Kingdom to jointly develop a new fighter, although the latter three had their own aircraft developments.

A number of factors led to the eventual split between France and the other four countries. Around 1984 France reiterated its requirement for a carrier-capable version and demanded a leading role. It also insisted on a swing-role fighter that was lighter than the design favoured by the other four nations. West Germany, the UK and Italy opted out and established a new EFA programme. In Turin on 2 August 1985, West Germany, the UK and Italy agreed to go ahead with the Eurofighter, and confirmed that France, along with Spain, had chosen not to proceed as a member of the project. Despite pressure from France, Spain rejoined the Eurofighter project in early September 1985. The four-nation project eventually resulted in the development of the Eurofighter Typhoon.

### Design Phase

In France, the government proceeded with its own programme. The French Ministry of Defence required an aircraft capable of air-to-air and air-to-ground, all-day and adverse weather operations. Unlike other contemporary European fighter projects that required some level of international collaboration and cost-sharing, France was the sole developer of the Rafale's airframe, avionics, propulsion system and armament, and as such the aircraft was to replace a multitude of aircraft in the French Armed Forces. The Rafale would perform roles previously filled by an assortment of specialised platforms, including the Jaguar, F-8P Crusader, Mirage F1C/CR/CT, Mirage 2000C/-5/N, Étendard IVP/M and Super Étendard.

During October–December 1978, prior to France's joining of the ECA, Dassault received contracts for the development of project ACT 92 (Avion de Combat Tactique, meaning "Tactical Combat Airplane"). The following year, the National Office for Aviation Studies and Research began studying the possible configurations of the new fighter under the codename Rapace (meaning "Bird of Prey"). By March 1980, the number of configurations had been narrowed down to four, two of which had a combination of canards, delta wings and a single vertical tail-fin. In October 1982, the French Ministry of Defence announced that Dassault would build a technology demonstrator named Avion de Combat expérimental (Experimental Combat Airplane), in short ACX. France wanted to collaborate with West Germany and the UK on the project, but was prepared to build the ACX by itself. In 1984, the government decided to proceed with a combat variant of the ACX due to the conflicting technical criteria of the respective FEFA participant nations.

The resultant Rafale A technology demonstrator was a large-delta winged fighter, with all-moving canards, embodying fly-by-wire (FBW) flight control system. Construction of the demonstrator commenced in March 1984, even before a contract was signed with the DGA, France's defence procurement agency. The technology demonstrator was rolled out in December 1985 in Saint-Cloud, and took its maiden flight on 4 July 1986 from Istres-Le Tubé Air Base in southern France. During the one-hour flight, the project's chief test pilot Guy Mitaux-Maurouard took the aircraft to an altitude of 11,000 metres (36,000 ft) and a speed of Mach 1.3. The 9.5-tonne (21,000 lb) demonstrator stopped in 300 metres (980 ft) upon landing.

Throughout the flight test programme, the Rafale A performed numerous day and night take-offs and landings aboard the carriers Clemenceau and Foch to investigate the pilot's field of view during carrier operations. It reached a speed of Mach 2 (2,450 km/h; 1,522 mph; 1,322.9 kn) and a height of 13,000 metres (42,000 ft). The demonstrator was initially powered by General Electric F404-GE-400 afterburning turbofans from the F/A-18 Hornet, instead of the Snecma M88, to reduce the risk that often comes with a first flight, and since the M88 was not considered sufficiently mature for the initial trials programme. It was not until May 1990 when the M88 replaced the port F404 in the demonstrator to enable the aircraft to reach Mach 1.4 and demonstrate supercruise, or sustained supersonic flight without use of afterburners. After 865 flights with four pilots, Rafale A was retired in January 1994.

At the time of the Rafale A's maiden flight, France entered unsuccessful talks with Belgium, Denmark, the Netherlands and Norway about a possible collaboration on the Rafale as a multinational project; at the time, Belgium was reportedly interested in the Rafale B. In June 1987, Prime Minister Jacques Chirac declared that the country would proceed with the US$30 billion project. Subsequently, on 21 April 1988, the French government awarded Dassault a contract for four Rafale prototypes: one Rafale C, two Rafale Ms and one Rafale B. The first out of an expected 330 Rafales was scheduled to enter service in 1996. However, the fall of the Berlin Wall, which signalled the end of the Cold War, as well as the need to reduce the national deficit, compelled the French government to drastically reduce its defence budget; the 1994 budget for the Rafale programme was cut by some US$340 million. This reduced the size of the Rafale orders, which Dassault and other companies involved claimed impeded production management and led to higher costs, and delayed the entry of the aircraft into service. The French Air Force was reorganised, the Mirage 5F was completely phased out and a total of 55 Mirage F1Cs were upgraded to a tactical fighter configuration, redesignated as Mirage F1CT. The budget cuts prolonged the Rafale's development considerably.

During the Rafale A flight test programme, the French government in 1989 looked at the F/A-18 Hornet as a potential replacement for the rapidly aging F-8 Crusader, which has been serving since the 1950s. The French Navy entered talks regarding the purchase of second-hand F/A-18s with Australia, Canada and the US, after the decision was made not to upgrade the Crusaders. The US Navy agreed to supply two F/A-18s to the French Navy for "interoperability testing" aboard the French aircraft carrier Foch. The French government did not proceed with a purchase of the twin-engine fighter.

## Design

The Rafale was developed as a modern jet fighter with a very high level of agility; Dassault chose to combine a delta wing with active close-coupled canard to maximize manoeuvrability. The aircraft is capable of withstanding from −3.6g to 9g (10.5g on Rafale solo display and a maximum of 11g can be reached in case of emergency). The Rafale is an aerodynamically unstable aircraft and uses digital fly-by-wire flight controls to artificially enforce and maintain stability. The aircraft's canards also act to reduce the minimum landing speed to 115 knots (213 km/h; 132 mph); while in flight, airspeeds as low as 15 knots (28 km/h; 17 mph) have been observed during training missions. According to simulations by Dassault, the Rafale has sufficient low speed performance to operate from STOBAR-configured aircraft carriers, and can take off using a ski-jump with no modifications.

Although not a full-aspect stealth aircraft, the cost of which was viewed as unacceptably excessive, the Rafale was designed for a reduced radar cross-section (RCS) and infrared signature. In order to reduce the RCS, changes from the initial technology demonstrator include a reduction in the size of the tail-fin, fuselage reshaping, repositioning of the engine air inlets underneath the aircraft's wing, and the extensive use of composite materials and serrated patterns for the construction of the trailing edges of the wings and canards. 70% of the Rafale's surface area is composite. Many of the features designed to reduce the Rafale's visibility to threats remain classified.
