This aircraft’s first drawings came out in October 1947. On December 30, Marcel Dassault signed the first contract to design, build and deliver three interceptor fighter planes. The prototype’s construction began on April 7, 1948, only six months after the first sketches were put on paper.

Reviving the standards of the Bloch aircraft from the years just before the war, and drawing on experience gained on the MB 150 series of fighters and its derivatives, the small Dassault team designed the simplest airframe possible: a small aircraft, light, inexpensive and as effective as the engine would allow.

The wing was fixed under the fuselage in such a way as to allow the articulated landing gear to be mounted underneath. The gear retracted laterally into the wingroot (for the struts) and under the fuselage (for the wheels). The fuselage, fully circular in cross-section, was designed around a pitot head frontal air intake (for optimal in-take with no boundary parasite layer) ; it contained a double air duct running either side of the pilot’s bucket seat, fuel tanks and a chamber for the Nene jet engine. The cockpit was pressurized, as the aircraft was designed to climb to 39,000 ft. The fuselage carried all the stabilizers (vertical and horizontal, the latter being effectively placed high on the rudder, and thus well clear of the slipstream from the low-slung wing).
