Developed from the D.500, the Dewoitine D.520 was a WWII, French, single-seat monoplane, which first saw combat action, as a fighter and ground-attack aircraft, in June-May 1940, during the Battle of France. Manufactured by the firm SNCAM/SNCASE, it had been introduced in early 1940, being in service with the French Air Force only a few months as France would be defeated by Germany in 1940. Despite the fact it was a maneuverable aircraft and had a good design, with low-wing and sturdy all-metal fuselage, the Dewoitine D.520 was not fast enough to be a match for the powerful Messerschmitt Bf 109E of the Luftwaffe. From mid 1940 onwards, about 200 of them, which had been captured by the Wehrmacht ground troops, would be in service with the German Air Force, carrying out ground-attack missions during the German invasion of Yugoslavia and Operation Marita the following year.
