This was one of the first jets. The configuration was obtained starting with a conventional propeller fighter design, and making room for the new type engine. As an immediate benefit of it, came a more forward position of the cockpit, and the tricycle landing gear. Intake duct goes under pilot seat. As the engine was in the center, the designs turned out to be similar in configuration to Bell P-39 Airacobra.

This airplane was designed in Argentina by french engineer Emile Dewoitine together with local engineers N. L. Morchio and H. J. Ricciardi. First flight was made on August 1947. In fact, there was another airplane that shared the same name, the Pulqui II , but it was designed by German engineer Kurt Tank, and was quite a different aircraft.

Detail of the intake. Nose intake needs a long duct that, in this airplane, had to pass through internal truss tubes and control pushrods. This kind of nose could be modified to give room to a radar antenna, (as was made in the F-86 and many others) but historically speaking, the nose intake eventually lost the battle in favour of the side scoop intake. |

The benefit of the forward and up position of the astrodome is a bigger visibility forward at the moment of taxiing especially, but also at take off. The front wheel had a lot of room for retraction, something impossible in the prop fighters of that times, because the huge piston engines that were used occupied all the space in the airplane starting from the leading edge of the airplane up to the propeller cone.
