Dassault Mirage III

In 1952, the French government issued its specification, calling for a lightweight, all-weather interceptor. Amongst the respondents were Dassault with their design, initially known as the Mirage I. Following favourable flight testing held over the course of 1954, in which speeds of up to Mach 1.6 were attained, it was decided that a larger follow-on aircraft would be required to bear the necessary equipment and payloads. An enlarged Mirage II proposal was considered, as well as MD 610 Cavalier (3 versions), but was discarded in favour of a further-developed design, powered by the newly developed Snecma Atar afterburning turbojet engine, designated as the Mirage III.

The Dassault Mirage III is a family of single/dual-seat, single-engine, fighter aircraft developed and manufactured by French aircraft company Dassault Aviation. It was the first Western European combat aircraft to exceed Mach 2 in horizontal flight, a feat which was achieved on 24 October 1958

A total of 95 Mirage IIICs were obtained by the French Air Force (Armée de l'Air, AdA), with initial operational deliveries in July 1961. The Mirage IIIC remained in service with the AdA until 1988.

The Armée de l'Air also placed an order for a two-seat Mirage IIIB operational trainer. Performing its first flight on 21 October 1959, it was developed in parallel with the Mirage IIIC. The fuselage was stretched about a meter (3 ft 3.5 in), while both cannons were removed to accommodate the second seat. The IIIB lacked radar and provision for the SEPR rocket was also deleted, although it could carry external stores if desired. The AdA ordered 63 Mirage IIIBs (including the prototype), including five Mirage IIIB-1 trials aircraft, ten Mirage IIIB-2(RV) inflight refueling trainers with dummy nose probes, used for training Mirage IVA bomber pilots, and 20 Mirage IIIBEs, with the engine and some other features of the multi-role Mirage IIIE. One Mirage IIIB was fitted with a fly-by-wire flight control system in the mid-1970s and redesignated Mirage IIIB-SV (Stabilité Variable), it was used as a testbed for the system in the later Mirage 2000.
