context_page_description: 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, ground support, in-depth strike, anti-ship strike and nuclear deterrence missions. The Rafale is referred to as an "omnirole" aircraft by Dassault.
  In the late 1970s, the French Air Force and French 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 UK, Germany, Italy and Spain to produce an agile multi-purpose fighter, the Eurofighter Typhoon. Subsequent disagreements over workshare and differing requirements led to France's pursuit of its own development programme. 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.
context_section_description: 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, Mirage F1C/CR/CT, Mirage 2000C/-5/N in the Armée de l'air, and the F-8P Crusader, Étendard IVP/M and Super Étendard in the Aéronavale.
  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, 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; 1,520 mph; 1,320 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
