380 DEWOITINE of the serial D500 have been built since the date of the first flight on Juin 19, 1932 . They are divided into:

  • 100 Dewoitine D 500 plus 3 bought by VENEZUELA
  • 142 Dewoitine D 501 plus 14 for export (Lithuanie)
  • 94 Dewoitine D510 plus 30 sold for export : Chine (24), Russie (1), Angleterre (1), Japon (2), Espagne (2),
  • 1 Dewoitine D 503

To date, out of the 336 aircrafts manufactured for the Air Force, 107 are listed in the list below :



The specifications of the C1 program, issued in 1930, require a speed of 327 km / h at 3500 m, a ceiling of 10000 m and an armament of at least 2 7.5 mm machine guns. In response, Dewoitine offers a low-wing single-seater fighter: the D500. The first flight took place in June 1932. The aircraft having won the contest, an order was passed in November 1933. The D500 is a modern aircraft: its construction is all metallic, and it has Cantilever wings. Combined with the Hispano-suiza 12Xbrs engine with 690 hp compressor, it reaches 360 km / h. The construction is outsourced to the Lioré & Olivier factory, better sized for a series construction of the Dewoitine D500. However, production is lower than expected due to delays in the delivery of the Hispano engine. The D500 is produced at 100 specimens, before being replaced by the D501, identical but equipped with a 20mm gun between the cylinders of the engine. The first D501 of series made its first flight in June 1936, and in total, 157 D501 will be built. The Fighter Groups equipped with D501 in 1935: the GC I / 3 and II / 3 are the only units in the world to use gun-equipped equipment. In 1936, 12 fighter squadrons were equipped with the new aircraft, in D500 or D501 version, while the D510 began to be delivered. The prototype of the D510 made its first flight in July 1936, with notable changes compared to the D501 (See version), it receives among others the new engine Hispano-suiza HS12Ycrs of 860cv. This engine allows it to become the first French aircraft to cross the 400 km / h mark. The production of this new version is launched in series in a difficult context : the aeronautical factories are in full nationalization which results in disorganization of the production tool and delays. In total, 120 D510 will be delivered but will be exceeded as soon as they are put into service: the Luftwaffe is already testing Messerschmitt ME109, and England its Hawker Hurricane ... In 1938, however, the D500 and its derivatives represent 70% of Service in the French Air Force.

On entering the war there are still many Dewoitine D500s in fighter schools, and sometimes in front-line units awaiting the arrival of the Bloch 152 or Morane MS406. All these "old" aircraft will happily be removed from service, to remain only in a patrol of defense in the hands of Polish pilots. At the armistice, there will be no more than forty copies.

In North Africa, the situation is a little different: the Dewoitine D500 and derivatives are still used in front-line units: this is the case of ERC 571 based in Casablanca; He received the D510, abandoned by the GCIII / 1 recently equipped with Morane Saulnier MS406 and sent to France. The last Dewoitine D510 will be used until the end of 1941, at the Autonomous Escadrille n � 6 stationed in Dakar.



Dewoitine D500
First version presented in response to the program C1 of 1930. Commanded by the market N � 661/1 of 7 March 1932, it is motorized by a Hispano-Suiza 12Xbrs of 500Cv, pushed to 650Cv thereafter. The Dewoitine D500 displays the mass of 1705Kg. He made his first flight on June 8, 1932 at the hands of Marcel Doret, then undergoes tests at STaé (Aeronautical Technical Services). In order to obtain export sales, it is presented, under the registration F-AKCK, to different foreign commissions. The aircraft will be damaged on 12 October 1934 in Francazal
Dewoitine D501
The D501 is very close to the Dewoitine D500. The main difference is the use of the gun engine Hispano-suiza 12Xcrs in place of the 12Xbrs. This engine allows to house a Hipsano-Suiza HS-9 gun of 20mm between the two rows of cylinder. The first series aircraft made its first flight on June 11, 1936.
Dewoitine D503

The Dewoitine D503 differs from the Dewoitine D501 by adopting a monojambe train and a wingspan reduced to 11.48m for a wing area of 15m �. It makes its first flight on April 15, 1935 and will be built with a single exemplary. Its monojambe train and front radiator provide superior performance to the D501, but it is already overtaken by the fighters presented in the C1 program of 1934. This aircraft Will become the personal plane of Colonel FONCK, great Ace of the first conflict.

Dewoitine D510
Cell No. 48 of the Dewoitine D500, powered by a Hispano-Suiza 12Ycrs of 860Ch, becomes the D510 n � 48. He made his first flight on 14 August 1934 at the hands of Marcel DORET. And became the first French fighter to pass 400 km / h. After the tests, the rudder and the flap are enlarged to solve lateral instability, and it receives an additional tank of 55 liters under the fuselage. Thus modified, it flew on May 14, 1935, and under the registration F-AODZ, it served as a demonstration plane before becoming the Parachute launcher D504 LP.
