The Dassault Mirage IV was a two-seat, supersonic bomber, which was in service with the French Air Force from 1964 to 1996. It had the capacity to carry advanced new weapons and avionics thanks to the effective upgrades made by Dassault's engineers. Designed to carry nuclear bombs and missiles, the Mirage IV was the aerial component of the French nuclear deterrence during the Cold War. It was the first European military aircraft capable of flying at sustained Mach-2 speed.
The Dassault Mirage IV was developed from the Mirage III, which was smaller, yet with the same configuration. To transform the interceptor into a bomber, it was necessary to scale it up by a factor of two. The prototype flew for the first time on June 17, 1959, being flown by test pilot Roland Glavany. Three days later, this prototype, the Mirage IV-O1, was authorized to make a pass over the Parish Air Show, with General Charles de Gaulle among the onlookers. It was introduced into service with the French Air Force (Armée de l'Air) on October 1, 1964, as the Mirage IV-A. A total of 62 strategic bombers would be produced.

Technical Description
The Dassault Mirage IV was a two-seat, twin-engine monoplane of all-metal construction. The layout and shape was almost identical to that of the Mirage III but it was longer, with a wider wing span, and it was powered by two jet engines instead of one. Therefore, it was fitted with large delta wing and the tail assembly lacked the horizontal plane, having only a large vertical fin. Thus, for take-off, the aircraft used the wing trailing edge flaps as elevators. The aircraft was equipped with air brakes that were mounted on the upper surface of wing root. The Mirage IV had an internal bomb-bay. The fuel tanks were located in the center of fuselage. The jet engines air intakes were situated on the sides of fuselage. Pilot and navigator sat in tandem in a twin-canopy cockpit; they were both provided with Hispano-built Martin-Baker BM.4 ejection seats.
