The Ikarus IK-2 was a high-wing, all metal, single seat, monoplane fighter aircraft of indigenous design built for the Yugoslav Air Force. The IK-2 was designed by Kosta Sivčev and Ljubomir Ilić.
The prototype, designated the IK-1, of the design was ordered from Ikarus A.D. in 1934, and was delivered for test in 1935. The aircraft was powered by a Hispano-Suiza 12Ycrs inline engine. The armament consisted of a 20 mm HS-404 cannon and two 7.92 mm Darne machine guns, both engine-mounted. The design was similar to the Polish PZL P.8, sharing its Pulawski wing (gull-wing) design, giving pilot an excellent view.
Captain Leonid Bajdak, a biplane advocate, tested the IK-1 in flight. During a full range of tests on the third flight the aircraft failed to pull out of a power dive and crashed. Bakdak bailed out and survived but claimed the IK-1 was not suitable as a fighter. Investigation of the wreckage disclosed that the failure was due to negligence in sewing a seam on one of the fabric covered wings, and therefore a decision was made to proceed with the second prototype, designated IK-2. The second prototype had metal skinned wings and was ready for test in June 1936. A new test pilot, Dobnikar, performed the preliminary flight tests, including a mock battle against a Hawker Fury, a biplane, flown by Captain Bajdak. The IK-2 outperformed the biplane in all respects.
Based upon these tests the Yugoslav Air Force ordered twelve IK-2 fighters, which were all delivered in 1937. In April 1941 when German forces invaded Yugoslavia, eight IK-2 fighters served mainly in strafing invading German columns and later the surviving aircraft were included in the Croatian Air Force.
A proposed development of the IK-2 was the IK-4, a two seat reconnaissance monoplane, but it was never ordered.
