context_page_description: The Dassault Mirage III is a family of single-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.
  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, 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. In October 1960, the first major production model, designated as the Mirage IIIC, performed its maiden flight. Initial operational deliveries of this model commenced in July 1961; a total of 95 Mirage IIICs were obtained by the French Air Force.
context_section_description: 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.
  Between 1967 and 1979, all the surviving Mirage IIIO(F) aircraft were converted to the Mirage IIIO(A) standard, which reconfigured them from the interceptor role to perform ground attack and aerial reconnaissance missions instead. In 1988, the Mirage III was finally withdrawn from RAAF service; 50 of the surviving fighters were exported to Pakistan in 1990. Several examples are preserved in museums around Australia; at least one of these is reportedly under restoration to an airworthy condition.
