The Dassault Mirage G was a French two-seat twin-engined variable-geometry prototype fighter, built by Dassault Aviation in the late 1960s. The aircraft was further developed into the twin-engine Mirage G4 and G8 variants as a multi-role jet fighter capable of both interception and nuclear strike missions. Although Dassault built and flew prototypes, the entire programme was terminated in the 1970s without the aircraft entering production.
