Dewoitine D.430

It was to have three Lorraine 9N Algol engines, an all-metal structure and to be capable of reconnaissance, observation, policing and bombing as well as medical evacuations or general transport.

It had a single spar at one third chord which tapered uniformly in depth outwards along the span and was reinforced with duralumin trellising.

[1] The three-part fuselage was flat-sided and tapered only slightly towards the tail, proving a large interior which could be adapted to a variety of tasks.

[1] It had a fixed undercarriage with its main wheels on V-struts hinged from the lower fuselage and on vertical shock absorbing oleo struts to the engine mountings.

[5] It remained in use for several years; in 1934 it showed the flag in Belgium[6] and took the Minister of Aviation to the French aerobatic contest in Algeria.
