The Mystere Delta design mated a Mystere-type fuselage powered by two British Viper turbojets with a delta wing and tail; flight trails began in June 1955, but the renamed Mirage I was really too small to have any future as an operational type, not having space for an effective radar, and with an armament that was restricted to a single AAM. The twin-engined Mirage II was not proceeded with, but development of the single Atar-engined Mirage III went forward. This retained the basic delta planform, but in much larger form, having more room for fuel and a Cyrano radar.
The prototype Mirage III flew in November 1956, and was followed up by a small number of preproduction Mirage IIIAs that were slightly enlarged; these were the first western European fighters to exceed Mach-2. The first production version was the Mirage IIIC fighter of 1960, with a full operational fit and a pair of 30mm DEFA cannon to back up the missile armament; in this regard, the Mirage was superior to the American Phantom, which would not be fitted with a gun until years later.
First flown on April 6, 1961 the Mirage IIIE was a slightly stretched all-weather fighter-bomber, immediately discernible from the IIIC by its enlarged intakes and repositioned cockpit. The Mirage IIIR was a reconnaissance version of the IIIE with cameras fitted in the nose, while the IIIRD model had a doppler navigation system.
Even as the Mirage was entering French service, switzerland was negotiating a deal to produce the type under license - the Mirage IIIS variant was designed to meet Swiss requirements, with a tailhook for operations from short wartime fields, Oerlikon cannon in place of the French guns, and provision for the AIM-4 Falcon AAM. The IIIS program was delayed, and cost overruns ultimately kept production limited to 58 examples.
