Bloch MB.81

1st Flight 1932

The MB.81 was a French military aircraft built as a flying ambulance, it was designed to carry one passenger, in or out of a stretcher.

Developed in response to a government-sponsored competition in support of the new doctrine of “aerial first aid”, it was employed exclusively in the overseas colonies, specifically Morocco and Syria.

Unlike the MB.80 prototype, the MB.81 had a closed cockpit and a somewhat larger cargo space.

This was the company’s first design to reach production.
