With the absorption of ANF-Mureaux in 1937 as a component of the SNCA du Nord (which also included Potez and retained the appellation for its products), Andre Brunet and his co-designers Lemaitre and Hubert continued the line of lightweight fighter development commenced with the ANF-Mureaux 190. In the autumn of 1938, work on a progressive development, the Potez 230, was begun. While possessing a number of features in common with the earlier fighter (eg, elliptical wings), the new aircraft was of more advanced design. Powered by a 670hp Hispano-Suiza 12Xcrs 12-cylinder liquid-cooled engine and having a proposed armament of one engine-mounted 20mm cannon and four wing-mounted 7.5mm machine guns, the Potez 230 was flown on 30 March 1940. When German forces occupied Villacoublay, the sole prototype of the Potez 230 was seized and transported to Germany for examination of the wing torsion box, which, of integral construction, was the first of its type to have been flown.
