The SNCAC NC.510 was a twin-engine French reconnaissance, army co-operation or advanced training aircraft, built in the late 1930s.

Between the engines and fuselage the wing was rectangular in plan and externally braced; the outboard panels were tapered cantilevers.

The aircraft carried three machine guns, one fixed in the nose and one moveable in each of the rear dorsal and the ventral positions.

There were racks for flares and for phosphorus bombs in addition to a mixture of handheld and remotely operated cameras for reconnaissance.

[2] The NC.510 first flew on 20 June 1938,[4] powered by two 574 kW (770 hp) Gnome-Rhône 9Kfr 9-cylinder air-cooled radials driving two-blade, wooden, fixed-pitch propellers.

By December that year it was on display at the Paris Aero Salon with 14-cylinder 680 hp (507 kW) Gnome-Rhône 14M double-row radial engines and three-blade propellers.
