Dassault Mirage G

The Dassault Mirage G, also known as the Mirage IIIG, was a variant of the Mirage family of supersonic warplanes with a variable-sweep wing. It grew out of French defence studies of swing-wing aircraft begun in 1963 in response to the American TFX programme, and out of the Dassault proposals that followed. Three prototypes flew: the single-engined, two-seat Mirage G, essentially a swing-wing version of the Mirage F2 that first flew on 18 November 1967, and two twin-engined Mirage G8 aircraft built as interceptors. The wings swept from 22 degrees forward to 70 degrees aft. The Mirage G crashed on 13 January 1971 after a total loss of electrical power. None of the variants entered production, and the two G8 aircraft survive on display in French museums.
