Only one prototype was completed; unsatisfactory performance led to the aircraft being superseded by a later design.
The fuselage was semi-monocoque with an elliptical cross-section housing a single Rolls-Royce Derwent 5 engine with the air intake in the nose and the ducting surrounding the cockpit.
The reduced internal fuselage volume forced the fuel tanks to be installed in the wings, which resulted in a significant reduction of its range.
The history of this aircraft was brief, limited to testing and evaluation of the only prototype, as its performance was considered unsatisfactory and in the meantime studies for the more developed FMA IAe 33 Pulqui II were quite advanced.
Nevertheless, its role in the history of aviation is quite significant as it was the first jet aircraft developed and built in Argentina and Latin America.
