The prototype MS.406 was in fact the fourth development MS.405 and first flew on 20 May 1938 with 642-kW (860-hp) His pano-Suiza 12Y31 and 'moteur-canon1 ,typifying the continental practice of using a hub-firing cannon to avoid the need to synchronize its fire. By April 1938 orders totalling 955 MS.406s had been placed for completion by September 1939 but in the event only 572 had been produced by that date, At the outbreak of war these aircraft equipped five groupes de chasse at Chartres and Dijon plus two in Algeria 29 aircraft had been shipped to Tunisia and 10 to Indo-China. By 1 0 May 1940 the number of combat-ready MS. 406s had actually dropped from 367 to 278 a situation quickly aggravated by the loss of 37 aircraft on the ground at Cambrai Damblain Vitry and Le Quesnoy on the first day. The MS.406 quickly proved to be outclassed in the air and during the Battle of France about 150 were lost in combat (plus some 100 on the ground). The aircraft's inferiority was acknowledged and by the time of the Armistice conversion to other aircraft was already being undertaken by 40610 MS groupes.

With a performance similar to the Hurricane it was still outclassed by the Bf 109 but incapable hands, undoubtedly agave good account of itself in battle. Best of all French fighters at the time of the great German attack in the West of May 1940 was the Dewoitine D.S20, although it was probably no better than the RAF's Hurricane Mk I moreover moreno than 36 had been delivered to a single groupe de chasse when the blow fell. Although the need for a fighter to replace the D.510 had been acknowledged as long ago as 1934 the 520's D design was not started until November 1936 the prototype was flown by Marcel Doret on 2 October 1938. Such delays were symptoms of the lethargy and procrastination that pervaded the French aircraft industry immediately before the war. Indeed it was not until 2 November 1939 that the first production D.520 was flown. First to receive the new fighter was GC 1/3 and this Groupe first met the Luftwaffe on 13 May, shooting down three Hs 126s and an He 111 without loss. Some 43 other aircraft were quickly delivered to GC II/3 GC II/7 GC III/3 and GC III/6 and as new aircraft were completed A6ronavale Escadrilles AC 123 and 4 were equipped with a further 52 before the armistice was signed. Production of the D.520 continued in the Vichy (unoccupied) zone and indue course a total of 235 D.520s served with Vichy forces in France and 202 in Africa. Highest-scoring French fighter pilot was Adjutant Pierre Le Gloan a pilot of GC III/6 who destroyed 1 8 enemy aircraft (out of his eventual total of 22) while flying D 520s Total production of the aircraft was 775.
