In 1941, the IK-3 is the most advanced locally built Yugoslav fighter. Designed by engineers Ilic and Sivcev, the IK-3 prototype make her maiden flight on April 14th, 1938. After the crash of the prototype on 19th january, 1939, the n°2 is used as prototype. The planes are delivered in March 1939 (n°2 to n°7) and Juiy 1940 (n°8 to 13), all being used by Grupa 51 in Zemun airfield, Belgrade. The modified n°7 is used as prototype of second order (25 units being in final assembly phase on 6th of April, 1941). The modified n°7 is 20 km/h faster than planes of first order.
During the German attack on 6 April, 1941, the IK-3s are employed for Belgrade north sector defence. During the fights, they shot down eleven enemy planes, but very quickly suffer huge attrition. Sgt. Semiz takes the N°7 (N°2155) at Rogozarski plant on 7th, evening, and fights the 11 th, gaining one victory.
