11/30/2010. Remarks by Johan Visschedijk: "The Société d'Études Aéronautiques (SEA) was formed in 1916 by Henry Potez and Marcel Bloch. Together with Louis Coroller, they designed in 1917 a two-seat fighter-reconnaissance aircraft, the SEA 4, which was powered by the new 370 hp Lorraine-Dietrich 12Da twelve-cylinder liquid-cooled engine. An equi-span two-bay biplane, the prototype flew in April 1918, and underwent official testing at Villacoublay on the 28th of that month.
As a result of this and subsequent operational evaluation at Le Plessis-Belleville and Perthe, 1,000 examples of the SEA 4 C2 were ordered. Potez, Bloch and an industrialist, Bessonneau, established the Société Anjou Aéronautique to fulfil part of this order, the remainder being contracted to SFCA (Société Anonyme Française de Constructions Aéronautiques), the Ateliers d'Aviation L Janoir and SAIB (Societe Anonyme d'Applications Industrielles du Bois).
The first series SEA 4 C2 was completed on Armistice Day, November 11, 1918, Anjou Aéronautique finishing 30 before going into liquidation.
