SNCAC NC.600

With the creation of the Societe Nationale de Constructions Aeronautiques du Centre by the fusion of the Hanriot and Farman concerns under the Law for the Nationalisation of Military Industries, major redesign was initiated of the Hanriot H.220 twin-engined three-seat fighter. The first result of this redesign was the H.220-2, which was displayed statically as the NC 600 in July 1939 at the Salon de l'Aeronautique held in Brussels. This aircraft was not, however, the genuine NC 600, which differed from the H.220-2 in having, among other changes, a revised wing. Whereas the wing of the H.220 had a leading edge perpendicular to the fuselage, both spars featuring several degrees of forward sweep, that of the NC 600 had some three degrees of leading edge taper and perpendicular spars (span and area remaining unchanged), thus removing the last commonality with the original H.220. Although the H.220-2 had not overcome the airflow turbulence generated by the wing centre section bracing struts which produced serious tail buffet under certain conditions, the SNCA du Centre persisted in retaining this feature for the NC 600, which flew for the first time on 15 May 1940. This aircraft, which introduced raised aft fuselage decking, redesigned endplate fins and rudders, and a raised tail assembly, was powered by two Gnome-Rhone 14M0/01 Mars radials each rated at 710hp for take-off. Armament consisted of two 20-mm HS 404 cannon plus two 7.5mm MAC 1934 machine guns firing forward and a 20mm weapon on a flexible mounting firing aft, this partially retracting into a slot in the fuselage decking. The NC 600 was proposed as a two-seat fighter, and although there is no record of an official order for this type, six were under construction when the Wehrmacht occupied Bourges.
