Dassault Mirage III
The Mirage III is a French tailless-delta fighter designed by Dassault Aviation in the 1950s. The first Western European combat aircraft to exceed Mach 2 in level flight, it was built in large numbers for France and for export, fought in the Middle East and the South Atlantic among other places, and remains in Pakistani service in upgraded form long after most operators retired it.
Why It Mattered
The Mirage III was the first Western European combat aircraft to exceed Mach 2 in level flight, a mark a pre-production aircraft reached in October 1958. Dassault Aviation built it as a light interceptor for the French Air Force, but it was the export market that made the type: few Cold War fighters were produced in such numbers for so many foreign customers. Its reputation was made in combat; Israeli success with the Mirage in the Six-Day War of 1967 was widely read as proof of the design. Production of the Mirage III passed 1,400 aircraft, and its tailless delta layout set the pattern for the French fighters that followed it.
Design Notes
Dassault shaped the Mirage III around the transonic area rule, pinching the fuselage into a "wasp waist" so that a single engine could push it past Mach 2. The wing was a tailless delta, with no separate tailplane: a simple, strong layout, but one that cost the aircraft at low speed, where take-off runs were long and landing speeds high. The intakes carried movable half-cone shock diffusers, known as souris ("mice"), adjusted as speed changed. Power came from a single SNECMA Atar afterburning turbojet — the Atar 9C of the Australian aircraft gave a maximum level speed of Mach 2.2 — and the standard armament was two 30 mm DEFA cannon with air-to-air missiles.
Operational History
The prototype first flew on 17 November 1956, and deliveries of the first major production version, the Mirage IIIC, began in July 1961. Israel became the type's most celebrated operator: in the Six-Day War of June 1967 its Mirages served as both air-superiority fighters and strike aircraft, and Israeli pilots were credited with 48 of the 58 Arab aircraft claimed destroyed in air combat during the war. In the Yom Kippur War of 1973 they flew air-to-air work alongside the Israeli-built Nesher, a derivative of the design; Israeli accounts claimed 106 Syrian and Egyptian aircraft shot down. Australia had selected the Mirage in 1961, ahead of rivals led by the F-104 Starfighter, and built it under licence with the Government Aircraft Factory as prime contractor. The RAAF's 116 aircraft served with five squadrons from 1965 to 1989. Argentina flew its Mirage IIIEAs during the Falklands War of 1982, where the lack of an aerial refuelling capability limited their usefulness over the British fleet.
Afterlife
The type's later working life owed more to secondhand sales and upgrades than to its first owners. When Australia stored its retired fleet, 50 aircraft were sold to the Pakistan Air Force in 1990. Pakistan had first acquired its Mirages between 1967 and 1977 and became the type's most durable operator, rebuilding used aircraft and upgrading many of them under Project ROSE. The Mirage III remains in service with the Pakistan Air Force, more than six decades after the first flight. The design also outlived its production run in derivatives such as the Mirage 5 and the Atlas Cheetah. Preserved examples sit in museums in several countries; the South Australian Aviation Museum, for one, displays a two-seat Mirage IIID gifted by the RAAF in 2018.
