IAe 33 Pulqui II

This aircraft, designed to fly at 1,200 Km/h (750 mph), would become one of the most sophisticated interceptor fighter planes in the world. Its appearance had much in common with the MiG-15 (USSR), and the F-86 Sabre (USA), which were designed by engineers who had once worked at the German factory where Tank had been the director.

The high-mounted negative-incidence wings were swept back 40°, even more than the Ta 183. The long fuselage was perfectly circular in section with the engine buried inside right at the center of gravity. The airframe was finished off with a graceful swept-back T-shaped tail. The pilot sat in a pressurized cockpit under a teardrop canopy.

Armament would include four fuselage-mounted 20 mm cannon. Contrary to the previous Pulqui I design by Emile Dewoitine, many design elements incorporated into the Pulqui II were new in the fields of aeronautical construction, placing the Argentinean aero industry amongst the forefront of aviation technology during those years.

The first flight of the IAe.33 Pulqui II no. 2 took place on 16 June 1950 with Osvaldo Weiss at the controls.

Today, the sole Pulqui I and the Pulqui II no. 5 are preserved at the Argentine Air Force’s Museum in Buenos Aires.
