The IK-02 can most charitably be described as obsolescent at the time of its first flight, but trials against a Hawker Fury biplane revealed that the IK-2 was superior on all counts and the Royal Yugoslav Air Force accordingly ordered 12 examples of the IK-2 production version that differed from the second prototype only in minor details.
IK-2 in action
Twelve aircraft made by Ikarus AD were taken over by RYAF between October 1938 and April 1939, and saw limited service up to time of Yugoslavia's defeat by Germany in April 1941. In the beginning IK-2 served with 6th Fighter Regiment in Zemun and from October 1939 with the 34th Fighter Group, 107 Fighter Squadron of the 4th Fighter Regiment in Zagreb. At the start of April war in 1941, eight of the fighters were still in service. First baptism of fire IK-2 received on April 9th when German Messerschmitt Bf109 attacked Rovine Air Base near Bosanski Aleksandrovac. During the combat one IK-2 and two Hawker Hurricane I where lost in exchange for two Messerschmitt. Aircraft were operated mainly in the ground-attack role. Some serviceable IK-2 where burned by there crews at end of the war, the three (four?) surviving IK-2 were then pressed into service with NDH Air Force.
