The F.70 was an unequal-span two-bay biplane with a wooden fuselage and was powered by a Renault 12Fe piston engine.

The aircraft could be fitted with a Gnome-Rhône Jupiter 9Aa radial engine and was then designated the Farman F.73.

Several aircraft of this series entered service with French airlines in the 1920s.

Lignes Aeriennes Latécoère used the aircraft to operate passenger and mail routes between Casablanca and Dakar and also from Algiers to Biskra.
