The IA 35 Huanquero was the first design from the DINFIA organisation (Argentina) to enter production. A twin-engined all metal (except for fabric covered ailerons) low-wing cantilever monoplane, it had a high-mounted tailplane with two fins and rudders and retractable tricycle landing gear. It was powered by two I.Ae. 19R El Indio radial engines.
The design team was led by professor Kurt Tank, former Focke Wulf designer who also designed the Pulqui II jet fighter based on the Focke-Wulf Ta 183 of WW2 era.
The prototype first flew on 21 September 1953 and was followed by a planned production batch of 100 aircraft. The first production aircraft flew on 29 March 1957 but less than half of the aircraft were built when production ceased in the mid-1960s.
