Destroyed in Second World War, Yugoslav industry slowly recovered under nationalized control. Preduzece SOKO formed 1951, building Westland Whirlwind and later Gazelle helicopters under licence. In 1957 began design of G2-A Galeb jet trainer (May 1961), which led to J-1 Jastreb single-seat attack/recon aircraft, both made and exported in large numbers. P-2 Kraguj piston-engined attack aircraft (1966) built in small series, but 'Jurom' launched large programme: see SOKO/Avioane. G-4 Super Galeb jet trainer (17 July 1978) built in substantial numbers for home (136) and export. By the 1980s, SOKO was working on the Novi Avion project, intended to develop an indigenous fourth-generation, supersonic multi-role fighter that would enabled the Yugoslav Air Force to be supplied with domestically-built modern fighters. The production was planned to begin around 1991; however, the outbreak of the Yugoslav wars and the enactment of an international arms embargo caused the project to be cancelled. During the early 1990s, the factory ceased aircraft production altogether. The facilities were partially dismantled and relocated to Serbia, where they were aligned with the Utva Aviation Industry in Pančevo which had already been working closely with SOKO in the manufacturing of Orao and Super Galeb.
