The MB.210 and MB.211 were the successors of the French Bloch MB.200 bomber aircraft built by Societé des Avions Marcel Bloch in the 1930s.

Development

The MB.210 derived from the MB.200 and differs in particular by its more deeply set, cantilever wing and the retractable undercarriage from their predecessor.

Developed as a private venture, the prototype MB.210 accomplished its first flight on 23 November 1934, powered by two 800 hp Gnome-Rhône 14Kdrs/grs radial engines and having a fixed undercarriage. Green 1967, p.124.] This was followed by a second prototype, the MB.211 Verdun, powered by 860 hp Hispano-Suiza 12Y V-12 liquid cooled engines and fitted with a retractable undercarriage, this flying on 29 August 1935. Green 1967, p.125.] Initial flight testing of this version was somewhat disappointing, so no further examples were built. Further progress with the MB.210, however, convinced the French Air Force to order series production, the first example of which flew on 12 December 1936. Green 1967, p.126.]

The satisfaction did not last very long, however, since it was underpowered and the engines of production aircraft were inclined to overheating. The type was grounded until its engines could be replaced by the more powerful and reliable Gnome-Rhône 14N, these engines first being tested in summer 1937. and had to be replaced. Green 1967, p.127.] Altogether 257 units were manufactured amongst companies as diverse as Les Mureaux over Potez-CAMS, Breguet, Hanriot, and Renault.

Operational history

In September 1939, the Bloch MB.210 equipped twelve bomber units of the French Air Force. At the time of Nazi Germany's attack on France in spring 1940, these squadrons were in the middle of a restructuring aimed at removing outdated aircraft from the front line. Up to the armistice on 25 June of the same year the MB.210 was used still for nocturnal bomb employments and shifted then to North Africa.
