The Mirage III is a supersonic fighter aircraft designed by Dassault Aviation during the mid-1950s. Dassault also built a multirole/strike variant of the aircraft, the Mirage IIIE.
The Mirage IIIE differed from the IIIC interceptor in having a 11.8 inch forward fuselage extension to increase the size of the avionics bay behind the cockpit. The stretch also helped increase fuel capacity, as the Mirage IIIC had marginal range and improvements were needed.
