Design and Development
Dassault designed the Mirage F1 as a private venture, using its own funds, as a successor to its Mirage III and Mirage 5 fighters, with the F1 being a smaller version of the Mirage F2 being developed for the French Air Force. It was of similar size to the delta-winged Mirage III and V, and was powered by a SNECMA Atar 9K turbojet as used in the Dassault Mirage IV, but unlike its predecessors, it shared the layout of a swept wing mounted high on the fuselage and a conventional tail surface as used by the F2.
The first prototype made its maiden flight on 23 December 1966. Despite the prototype crashing on 18 May 1967 due to flutter, killing its pilot, an order for three prototypes was placed on 26 May 1967, the larger and more expensive F2 being abandoned.
Although it has a smaller wingspan than the Mirage III, the F1 nevertheless proved to be clearly superior to its predecessor. It can carry up to 43% more fuel, has a shorter take-off run and better maneuverability.
In order to comply with the French Air Force's requirement for an all-weather interceptor, the first production Mirage F1C was equipped with a Thomson-CSF Cyrano IV monopulse radar. The later Cyrano IV-1 version added a limited look-down capability. However Mirage F1 pilots reported that the radar can easily overheat, reducing its efficiency. First deliveries to the French Air Force took place in May 1973, entering squadron service with EC 2/30 Normandie-Niemen in December that year. Initially, the aircraft was armed with two internal 30 mm cannons, and a single Matra R530 medium-range air-to-air missiles carried under the fuselage. It was replaced after 1979, when the improved Matra Super 530 F entered into service with the French Air Force. In 1977, the R550 Magic was released. The F1 has these missiles mounted on rails on the wingtips. Around the same time, the American AIM-9 Sidewinder became part of the Mirage F1's armament, after the Spanish and Hellenic Air Forces requested integration of the Sidewinder on their own Mirage F1CE and CG fighters.
The 79 aircraft of the next production run were delivered during the period March 1977 to December 1983. These were of the Mirage F1C-200 version with a fixed refuelling probe, which required an extension of the fuselage by 7 cm.
The Mirage F1 served as the main interceptor of the French Air Force until the Dassault Mirage 2000 entered service.

Famous quotes containing the words design and/or development:
“What but design of darkness to appall?—
If design govern in a thing so small.”
—Robert Frost (1874–1963)
“For decades child development experts have erroneously directed parents to sing with one voice, a unison chorus of values, politics, disciplinary and loving styles. But duets have greater harmonic possibilities and are more interesting to listen to, so long as cacophony or dissonance remains at acceptable levels.”
—Kyle D. Pruett (20th century)
