The Dewoitine D.510 was the latest of the D.500 series of all-metal open cockpit fixed-undercarriage monoplane fighters used by the Armée de l'Air in the 1930's. The initial D.500, designed by Emile Dewoitine , was based on specifications issued in 1930 by the air ministry, and was to be a replacement for the Nieuport 62 . The prototype first flew on June 18, 1932.

The D.500 was France's first modern monoplane fighter. The D.501 and D.510 featured an engine-mounted 20 mm cannon firing through the propeller spinner as well as two underwing rifle-calibre machine-guns. The aircraft was equippable with oxygen and shortwave radio.

Active service

The D.501 entered service in July, 1935. The D.510 entered service in September of 1936. For the time, they were highly maneuverable and well armed, with standard armament on fighters of the mid 1930's generally entailing only 2 or 4 machine guns. Upon entering service, these planes became the primary fighters employed by the Armée de l'Air until their replacement by the newer Morane-Saulnier M.S.406 in 1939. As of September, 1939, the D.500/501 had been relegated to regional defense squadrons. Sixty D.510 still equipped three French Air Force groupes. The majority were replaced or withdrawn to North Africa prior to the German Blitzkrieg of May 10, 1940.

Seven D.500s originally sold to Latvia and two D.510s ostensibly intended for the Emirate of Hedjaz saw service in the Spanish Civil War, arriving in mid-1936. They served the Republican forces. The two 510s were posted to the 71st Coastal Defense Group. Neither engaged enemy fighters. In 1938, one was irrepairably damaged while landing and the other was destroyed on a runway during a bombing attack..

In 1938, Chinese D.510s saw action against the Japanese.
