(SNCAC). The design anticipated the government specification MT/CPT-9 for a "combat scout seaplane" for the Forces Aériennes de Mer, which was circulated amongst manufacturers in May 1935. Farman revised the F.410 to accommodate this specification and four other French manufacturers also built prototypes to it. There were further changes to MT/CPT-9 in March 1937. Post-nationalisation, the F.410 was renamed the SNCAC NC.4-10. The twin engine NC.4-10 was an all-metal aircraft.

When the NC.4-10 first flew, piloted by Lucian Coupet on 10 July 1939, it was powered instead by a pair of 890 hp (635 kW) Gnome-Rhône 14Knrs/ors 14-cylinder radials, mounted on the upper wing surface.
