Design and development

To meet a requirement to use as an engined testbed for Turboméca turbojets, Fouga comined two CM.8 fuselages. It used the port and starboard outerwings with a new wing centre section to join the two fuselages. The V-tails fitted to each fuselage were joined at the top in a "W" configuration. The type was designated the Fouga CM.88-R Gemeuax I and first flew 6 March 1951, it was fitted with two Turboméca Piméné turbojet, one on top of each fuselage. Further variants were produced as the engine fit was changed.

Variants

;Gemeaux I:Original configuration with two 220 lb (100 kg) Turboméca Piméné turbojet engines, first flown 6 March 1951.;Gemeaux II:Designation when powered by one 606 lb (275 kg) Turboméca Marboré I turbojet engine, first flown 16 June 1951.;Gemeaux III:Designation when powered by one prototype 772 lb (350 kg) thrust Turboméca Marboré II turbojet engine and first flown on 24 August 1951. A production version of the engine with 882 lb (400 kg) thrust was flown on 2 January 1952.;Gemeaux IV:Designation when powered by one 441 lb (200 kg) thrust Turboméca Aspin I turbojet engine, first flown on 6 November 1951.;Gemeuax V:Final designation when powered by one 794 lb (360 kg) thrust Turboméca Aspin II turbojet engine, first flown on 21 June 1952.
