The first of the VG-30 series to enter production, the VG-33 was intended to be a rival for the Dewoitine D.520, Morane-Saulnier M.S.450 and Ouest CAO 200, and a possible successor to the Morane-Saulnier M.S.406. . The type began it's test programme on 24th May 1939, leading to a production contract for 220 examples being placed with Chantiers Aero--Maritimes de Seine in September 1939. This was subsequently increased to 1,000, but only 19 had been completed by the time France surrendered in June 1940, by which time the VG.33 had already served as the basis for the single prototypes of the VG.34, VG.35 and VG.36.
The VG-33 was powered by an 860 hp Hispano-Suiza 12Y31 inline engine, giving the type a max speed of 347 mph (558 km/h) and normal range of 746 miles (1,200 km). Armament comprised a single 20 mm HS 404 autocannon and four 7.7 mm MAC 1834 M39 machine guns. Measuring 28 ft 02/3 in (8.55 m)in length, 10 ft 10 1/2 in (3.31 m) in height with the tail up, and 35 ft 5 1/4 in (10.80 m) across the wingspan, the VG-33 had an empty weight of 4,519 lb (2,050 kg, increasing with normal load to 5,855 lb (2,656 kg).
