SNCAM (Dewoitine) · France · first flew 1939 · bomber
The Dewoitine D.770 was a prototype French twin-engined attack aircraft of the late 1930s, intended as a replacement for the Breguet 693. No production followed.
Recognition (WEFT)
| W — Wings | Mid-mounted, straight |
|---|---|
| E — Engines | 2 × piston, wing-mounted |
| F — Fuselage | 9.75 m fuselage |
| T — Tail | Conventional |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Mid-mounted cantilever monoplane wing with two engines
- Nose-mounted 20 mm cannon and two machine guns
- Retractable tailwheel undercarriage
A mid-wing, stressed-skin all-metal monoplane with a monocoque fuselage and a crew of three protected by 150 kg of armour. It carried eight 50 kg bombs in a bomb bay.

History
In August 1937 the French Air Ministry released a specification for a light attack bomber and the nationalised Dewoitine company, SNCAM, proposed a three-seat twin-engined aircraft. The prototype was completed at Toulouse in spring 1939 and made its maiden flight on 27 June 1939, flown by Marcel Doret.
Variants
A second prototype, the D.771, was to have two Gnome-Rhone 14N radial engines instead of the two Hispano-Suiza 12Y V12s. It was completed in December 1939 but never flew.
Where you'll see it
The D.770 showed good speed but suffered from engine cooling problems and poor stability. Testing was incomplete at the Franco-German Armistice in June 1940, and both prototypes were scrapped in 1941.
