Ikarus S-49 The Ikarus S-49 was a Yugoslav single-seat, single-engine fighter

Ikarus S-49

aircraft built for the Yugoslav Air Force (Serbo-Croatian: Ratno vazduhoplovstvo i protivvazdušna obrana – RV i PVO) shortly after World War II. Following the Tito–Stalin Split in 1948, the RV i PVO was left with an aircraft inventory consisting of mostly Soviet aircraft. Unable to acquire new aircraft or spare parts for its existing fleet, the RV i PVO turned to its domestic aviation industry in order to create an indigenous design to fulfill the need for additional aircraft. The result was the S-49A, designed by Kosta Sivčev, Svetozar Popović and Slobodan Zrnić, on the basis of the pre-war Rogožarski IK-3. The S-49A was surpassed by the improved S49C, featuring an all-metal construction and a more powerful engine. A total of 45 S-49A and 113 S-49C were produced by the Ikarus Aircraft Factory in Zemun. The last aircraft were retired

Development After the Resolution of Informbiro in 1948 and the resulting breakup with the Soviet Union, Yugoslavia was forced to rely on its domestic military industry. The same constructors that built the Rogozarski IK-3 (designers Ljubomir Ilic, Kosta Sivcev, Slobodan Zrnic) before the war, engineers Kosta Sivcev, Slobodan Zrnic and Svetozar K. Popovic, used existing technical documentation of the IK-3 to construct a new fighter aircraft, the Ikarus S-49. The first prototype of the S-49A flew in June 1949. The first operational aircraft were delivered to combat units at the beginning of 1950. https://en.wikipedia.org/wiki/Ikarus_S-49

Description The S-49A was of mixed construction, with Soviet built VK-105 engines which were no longer available after 1948. Therefore, it was decided to produce a new version of the aircraft powered by the similar French Hispano-Suiza 12Z-17 engine. Because of the bigger and heavier engine, the new aircraft had to be of all-metal construction with a much longer nose. While the aircraft was mainly built by Ikarus, the wings and tail were built by the SOKO factory in Mostar.[1] The armament remained the same as with the Ikarus S-49A and it consisted of one 20 mm Mauser MG-151/20 autocannon produced by Germany during World War II and two 12.7 mm Colt Browning machine guns. In addition, under wing racks for two 50 kg bombs or four 127 mm HVAR missiles were provided.

Operational At the beginning of 1952, the Ikarus S-49C was introduced into the units of the Yugoslav Air Force. About 130 S-49C were produced during the 1950s and they remained in service until 1961.[1]

Variants S-49A - mixed construction and Klimov M-105 engine (45 built) S-49B - planned version powered by a Daimler-Benz engine; unbuilt. S-49C - all-metal construction and Hispano-Suiza 12Z engine (113 built)
