The FMA IAe 33 Pulqui II was a jet fighter aircraft designed by Kurt Tank in the late 1940s in Argentina, under the Perón government, and built by the Fábrica Militar de Aviones (FMA). Embodying many of the design elements of the wartime Focke-Wulf Ta 183, an unrealized fighter project, the FMA envisioned the IAe 33 Pulqui II as a successor to the postwar Gloster Meteor F4 in service with the Fuerza Aérea Argentina. The Pulqui II's development was comparatively problematic and lengthy, with two of the four prototypes being lost in fatal crashes. Despite one of the prototypes being successfully tested in combat during the 1955 Revolución Libertadora, the political, economic and technical challenges faced by the project meant that the IAe 33 was unable to reach its full potential, and the Argentine government ultimately chose to purchase F-86 Sabres from the United States in lieu of continuing development of the indigenous fighter to production status.

Kurt Waldemar Tank was a German aeronautical engineer and test pilot who led the design department at Focke-Wulf from 1931 to 1945. He was responsible for the creation of several important Luftwaffe aircraft of World War II, including the Fw 190 fighter aircraft, the Ta 152 fighter-interceptor and the Fw 200 Condor airliner. After the war, Tank spent two decades designing aircraft abroad, working first in Argentina and then in India, before returning to West Germany in the late 1960s to work as a consultant for Messerschmitt-Bölkow-Blohm (MBB).
