Falcon Models FA725001 French Dassault Mirage IIIC Interceptor - No. 31, EC 2/10 Seine, France, May 1978 (1:72 Scale)
"Obsolete weapons do not deter."
- British Prime Minister Margaret Thatcher
The Mirage III family grew out of French government studies begun in 1952 that led in early 1953 to a specification for a lightweight, all-weather interceptor capable of climbing to 18,000 m (59,040 ft) in six minutes and able to reach Mach 1.3 in level flight.
Dassault's response to the specification was the Mystere-Delta 550, a sporty-looking little jet that was to be powered by twin Armstrong Siddeley MD30R Viper afterburning turbojets, each with thrust of 9.61 kN (2,160 lbf). A SEPR liquid-fuel rocket motor was to provide additional burst thrust of 14.7 kN (3,300 lbf). The aircraft had a tailless delta configuration, with a 5% chord (ratio of airfoil thickness to length) and 60 degree sweep.
The tailless delta configuration has a number of limitations. The lack of a horizontal stabilizer means flaps cannot be used, resulting in a long take-off run and a high landing speed. The delta wing itself limits maneuverability; and suffers from buffeting at low altitude, due to the large wing area and resulting low wing loading. However, the delta is a simple and pleasing design, easily built and robust, capable of high speed in a straight line, and with plenty of space in the wing for fuel storage.
The first prototype of the Mystere-Delta, without afterburning engine or rocket motor and an absurdly large vertical tailfin, flew on 25 June 1955. After some redesign, reduction of the tailfin to more rational size, installation of afterburners and rocket motor, and renaming to Mirage I, the prototype attained Mach 1.3 in level flight without the rocket, and Mach 1.6 with the rocket lit in late 1955.
However, the small size of the Mirage I restricted its armament to a single air-to-air missile, and even before this time it had been prudently decided the aircraft was simply too tiny to carry a useful warload. After trials, the Mirage I prototype was eventually scrapped.
Dassault then considered a somewhat bigger version, the Mirage II, with a pair of Turbomeca Gabizo turbojets, but no aircraft of this configuration was ever built. The Mirage II was bypassed for a much more ambitious design that was 30% heavier than the Mirage I and was powered by the new SNECMA Atar afterburning turbojet with thrust of 43.2 kN (9,700 lbf). The Atar was an axial flow turbojet, derived from the German World War II BMW 003 design.
The new fighter design was named the Mirage III. It incorporated the new area ruling concept, where changes to the cross section of an aircraft were made as gradual as possible, resulting in the famous "wasp waist" configuration of many supersonic fighters. Like the Mirage I, the Mirage III had provision for a SEPR rocket engine.

Historical Account: "In the Wake of Guynemer" - Many consider the Armee de l'Air to have been the first professional air force in the world. The French took active interest in developing their air force and had the first fighter pilots of World War I. During the interwar years, however, particularly in the 1930s, the quality fell when compared with the Luftwaffe, which crushed both the French and British air forces during the Battle of France.
In the post World War II era, the French made a concerted and successful effort to develop a homegrown aircraft industry.
Dassault Aviation led the way forward with their unique and effective delta-wing designs, which formed the basis for the famous Mirage series of jet fighters. The Mirage repeatedly demonstrated its deadly abilities in the Six-Day War and the Gulf War, becoming one of the most popular and well-sold aircraft in the history of military aviation along the way.
Currently, the French Air Force is expanding and replacing. The French are awaiting the A400M military transport aircraft, which is still in developmental stages, and the integration of the new Rafale multi-role jet fighter, whose first squadron of 20 aircraft became operational in 2006 at Saint-Dizier.
