The Ikarus Aero 2 was a piston-engined military trainer aircraft built in Yugoslavia in the years following World War II, although the design pre-dated the war.

## Design and development

The Ikarus Aero-2 was developed as a replacement for the Zmaj Fizir FN, which had been the most commonly used training aircraft of the Yugoslav Royal Air Force up until 1941. The Ikarus Aero-2 was designed by Boris Cijan and Đorđe Petković. Also at same time, was started project on two different aircraft, low-wing Ikarus MM-2 for advanced train and low-wing Rogožarski Brucoš for basic train. First flight test was made on April 20, 1940 and test pilot was Vasilije Stojanovic. 248 plane were eventually built, serving from 1948 to 1959 (380 built according to.

Powerplant was to be the de Havilland Gipsy Major because of its successful use in similar trainer aircraft built in other countries. The Aero 2 was a low-wing monoplane that seated the student and instructor in tandem, open cockpits (although later versions added a canopy to enclose them). Undercarriage was fixed and used a tailskid.
