Competing with the ANF-Mureaux 190 to meet a Service Technique de l'Aeronautique specification for a lightweight fighter, the C 710 Cyclone, designed by Marcel Riffard, was developed from the Coupe Deutsch de la Meurthe racing monoplanes. It was of wooden stressed-skin construction with a 500hp Renault 12R 01 12-cylinder inverted-Vee air-cooled engine.
First flown on 18 July 1936, the C 710-01 was subsequently fitted with two drum-fed 20mm HS-9 cannon in the wings, and was tested at Guyancourt and Villacoublay throughout 1937. On 1 February 1938 it crashed in the Verrieres forest.
Two additional airframes had been built, the second of these being completed as the C 710-02 which differed from the first prototype in having redesigned vertical tail surfaces, taller and more angular. Further development of the basic design concentrated on derivatives embodying retractable undercarriages (C 713, C 714) but were brought to a halt by the German occupation of France in 1940
