, the company was from its onset focused upon the manufacture of military aircraft. 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. Some officials, like Bloch, decided to withdraw from the aviation sector entirely in light of the poor economic prospects of the early 1920s aviation market.


History

The formation of the Société d’Etudes Aéronautiques (SEA) can be largely attributed to the undertakings of two French engineers,

fighter under licence. However, it soon developed its original designs and put those into production as well. Several early aircraft, starting with the SEA I, proved somewhat unsatisfactory and requiring further development. However, one such aircraft, the SEA IV, was selected for production for the French military. The " Ministère de l'Armement et des Fabrications de guerre" (Ministry of Armament and War Production) opted to place an order for 1,000 aircraft, which were intended to be produced at a rate of 200 per month and to be fulfilled by early 1919. To meet this rapid demand, Potez and Bloch founded a separate company, the ''Compagnie Anjou Aéronautique'' ("Anjou Aeronautical Company"), to undertake their production. This entity was established at

that marked the end of the conflict. Without a major ongoing war driving demand, peace quickly led to a major downturn in the sale and production of aircraft, pushing many aviation companies to the brink. The French Government's aircraft manufacturing department allegedly lacked interest in providing support to any of the nation's manufacturers. Accordingly, many companies and individuals alike decided to withdraw from the aviation sector during the late 1910s and early 1920s in favour of other endeavours. SEA was
