Dewoitine D.520 (Paperback)
In 1936 the D-513 fighter designed by Emil Dewoitine made its first flight. It was supposed to be the successor of the slightly outdated D-500 and D-510 models, and built according to modern trends: with a closed cabin and a retractable undercarriage. Unfortunately, the tests turned out to be very disappointing. At the same time, as a result of the nationalization of the aviation industry, Dewoitine's industries were absorbed by the SNCAM. Dewoitine, however, did not give up on the project and, in cooperation with his engineers, developed a new model - the D-520.
