Ikarus S-49C 2400 Yugoslavian Air Force. The Ikarus S-49, based on Yugoslavia’s pre-war IK-3, but developed by 1952 into an all-metal machine powered by a Hispano-Suiza engine from France. Although fairly soon superseded by modern US jets, 112 S-49Cs were built by Ikarus and Soko by 1954 and served till 1961. This is the only surviving example in the world. | Phil Glover.
