Development
After the Resolution of Informbiro in 1948 and breakup with Soviet Union, Yugoslavia was forced to rely on its domestic military industry. The same constructors that built the Rogozarski IK-3 before the war, engineers Kosta Sivcev, Slobodan Zrnic and Svetozar Popovic, used existing technical documentation of IK-3 to construct a new fighter aircraft, the Ikarus S-49. The first prototype of the S-49A flew in the June 1949. The first operational aircraft were delivered to combat units at the beginning of 1950.
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 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. The armament remained the same as with Ikarus S-49A and it consisted of one 20 mm MG-151 German cannon and two 12.7 mm Colt Browning machineguns. In addition, under wing racks for two 50 kg bombs or four 127 mm HVAR missiles were added.
At the beginning of 1952, the new fighter aircraft Ikarus S-49C was introduced in to the units of Yugoslav Air Force. About 130 S-49C were produced during the 1950s and they remained in service until 1961.

Famous quotes containing the word development:
“The Cairo conference ... is about a complicated web of education and employment, consumption and poverty, development and health care. It is also about whether governments will follow where women have so clearly led them, toward safe, simple and reliable choices in family planning. While Cairo crackles with conflict, in the homes of the world the orthodoxies have been duly heard, and roundly ignored.”
—Anna Quindlen (b. 1952)
“I do seriously believe that if we can measure among the States the benefits resulting from the preservation of the Union, the rebellious States have the larger share. It destroyed an institution that was their destruction. It opened the way for a commercial life that, if they will only embrace it and face the light, means to them a development that shall rival the best attainments of the greatest of our States.”
—Benjamin Harrison (1833–1901)
“Women, because of their colonial relationship to men, have to fight for their own independence. This fight for our own independence will lead to the growth and development of the revolutionary movement in this country. Only the independent woman can be truly effective in the larger revolutionary struggle.”
