FMA IAe 33 "Pulqui II"
One of famed designer Kurt Tank's final projects, the Argentinian jet fighter prototype known as the "Pulqui (Arrow) II." It was based on research and engineering conducted for Nazi Germany's Focke Wulf Ta 183 program, which was in the early stages of prototype conduction at the war's end. Tank and his team, with Argentine help, continued iterating on the design and constructed four prototypes during the rule of Juan Perón's government. Due to design and manufacturing flaws, the program met several delays and was halted when Tank's contract expired in January 1955. Tank and his team fled the country after the fall of the Perón government later that year, and the only remaining prototype was used against the
Revolución Libertadora, a military coup against President Perón. In 1956, a record-breaking flight from Córdoba to Buenos Aires was planned to showcase the aircraft. The flight was successful, however on the return leg the Pulqui II's oxygen system failed, causing the semi-conscious pilot to land hard, collapsing the gear and damaging the aircraft beyond repair. In 1957, despite the United States having offered 100 used F-86 Sabre aircraft to Argentina, a fifth and final prototype was ordered designated Pulqui IIe. The aircraft, which was visually nearly identical to it's predecessor, was finished in 1959 and began flight testing in September of that year. Changes had been made to reduce the unstable stall characteristics of the aircraft at high angles of attack, as well as increasing the range of the aircraft by fitting it with a "wet wing" for increased fuel capacity. Because of the political ties to the old government and the aircraft's now dated design, the program was concluded in 1960 after short use as a transonic research aircraft and the final prototype was placed in storage.
