The FMA IAe.30 (IA30) Ñancú ( Eaglet ) was a prototype fighter/fighter-bomber developed by the Argentinian company FMA in the years after World War 2.
Commissioned by the Argentine Air Force engineer K. Pallavicino, the aircraft was first flown on 18 July 1948, piloted by FMA test pilot Edmundo Osvaldo Veyst. Originally conceived as a plane escort fighter, Its armament consisted of six 20 - mm Oerlikon cannon. However, in the course of work on the plane Air Force Command of Argentina decided to refocus it as a light attack aircraft. For these purposes, suspension arm components were installed under the wings and fuselage, allowing easy use of bombs weighing up to 250 kg and two launchers with five rockets. The guns were replaced with Swiss produced 20 mm Hispano 804s.
In early August 1948 the prototype flew from Cordoba to Buenos Aires at an average speed of 650 km / h on approximately 60% of engine power. Such high flight data , supplemented with excellent maneuverability, were sufficient grounds for the Argentine Air Force ordering a batch of 210 aircraft. However, the order was not executed for financial reasons, and further work on the program folded .
The only aircraft was transferred to the second squadron of the Argentine Air Force.
