Société d'Études Aéronautiques

It quickly found work producing large numbers of combat aircraft on behalf of the French military.

However, following the end of the conflict, a major glut in surplus aircraft and the cancellation of many outstanding orders rapidly pushed the company into dire straights.

The formation of the Société d’Etudes Aéronautiques (SEA) can be largely attributed to the undertakings of two French engineers, Henry Potez and Marcel Bloch.

[1] Prior to SEA, Potez and Bloch had been talented aeronautical engineers that decided to form a partnership to development and manufacture of their original design of propellers, establishing the Société des Hélices Éclair.

However, they soon sought to go beyond just manufacturing components, but to undertake the design and construction of whole aircraft, thus, they both joined forces with another friend, Louis Coroller, to establish SEA.
