It was the first Western European combat aircraft to exceed Mach 2 in horizontal flight. The Mirage III was produced in large numbers for both the French Air Force and a wide number of export customers. Prominent overseas operators of the fighter included Argentina, Australia, South Africa, Pakistan and Israel, as well as a number of non-aligned nations. Often considered to be a second-generation fighter aircraft, the Mirage III experienced a lengthy service life with several of these operators; for some time, the type remained a fairly maneuverable aircraft and an effective opponent when engaged in close-range dogfighting. During its service with the French Air Force, the Mirage III was normally armed with assorted air-to-ground ordnance or R.550 Magic air-to-air missiles. Its design proved to be relatively versatile, allowing the fighter model to have been readily adapted to serve in a variety of roles, including trainer, reconnaissance and ground-attack versions. Australia first showed an official interest in replacing its CAC Sabre with the Mirage III in 1960, and initially considered a variant powered by a licence-built variant of the Rolls-Royce Avon turbojet (used by the CAC Sabre). While an experimental Avon-powered Mirage III was built as a prototype and flown in trials, it did not result in use of the Avon by a production variant. The Australian government decided that the Royal Australian Air Force (RAAF) would receive a variant based on the Mirage IIIE and powered by the SNECMA Atar engine, built under license by Government Aircraft Factories (GAF) at Fishermans Bend, Melbourne. Known as the Mirage IIIO or GAF Mirage, the Australian variant differed from the Mirage IIIE mainly in its avionics. The other major Australian aircraft manufacturer at the time, the Commonwealth Aircraft Corporation (CAC), also based in Melbourne, was also involved in the project, producing the Atar engine under licence. Initially, Dassault provided a pair of pattern aircraft, the first of these flying in March 1963, which were transported to Australia and used to aid technicians at GAF in establishing their own assembly line for the type. GAF produced three variants: the Mirage IIIO(F), which was an interceptor, the Mirage IIIO(A), a surface attack aircraft and the twin seat Mirage IIIO(D), a fighter lead-in trainer. GAF completed 48 Mirage IIIO(F), 50 Mirage IIIO(A) and 16 Mirage IIIO(D) aircraft. For more details, click here, and here.
