Arsenal VG 39

The final development in the VG 30 series of fighters to be flown, the VG 39 commenced its flight test programme on 3 May 1940, and the prototype differed from the VG 33 primarily in having a 1200hp Hispano-Suiza Type 89ter 12-cylinder liquid-cooled engine with an elongated propeller shaft, a revised wing structure which retained the profile and contours of the earlier wing, and a wing-mounted armament of six 7.5mm MAC 1934 M39 machine guns. During flight testing the prototype VG 39 attained a maximum speed of 625km/h at an altitude of 5750m. The planned production model, the VG 39bis, was to have embodied a fuselage similar to that of the VG 36 and to have supplemented the wing armament with a 20mm engine-mounted cannon, the definitive model having a 1600hp Hispano-Suiza 12Z engine.
