TheCaudron C.690 was a single-seattraining aircraft developed inFrance in the late 1930s to trainfighter pilots to handle high-performance aircraft. It was a conventional low-wingcantilevermonoplane that bore a strong resemblance to designerMarcel Riffard'sracer designs of the same period. Caudron attempted to attract overseas sales for the aircraft, but this resulted in orders for only two machines - one fromJapan, and the other from theUSSR. In the meantime, the first of twoprototypes was destroyed in a crash that killed René Paulhan, Caudron's chief test pilot.
Despite this, theArmée de l'Air eventually showed interest in the type, and ordered a batch of a slightly refined design. The first of these was not delivered until April 1939, and only 15C.690Ms were supplied before the outbreak ofwar.
