The IAR-93 Vultur/Soko J-22 Orao was the result of a collaboration between the Romanian IAv (Intreprinderea De Avioane Bucuresti) company and SOKO of Yugoslavia, stemming from a common requirement in both countries for a twin-jet close-support and ground-attack aircraft. The initial design was contracted out to the Institute of Aviation in Romania and its counterpart in Yugoslavia. Each country constructed prototypes powered by two licence-built Rolls-Royce Viper Mk 632 41Rs, and the first flights took place simultaneously in October 1974. Production of the initial batch of 20 Romanian aircraft, which are designated IAR-93A, began in 1979, with SOKO commencing production of the similar J- 22 in 1980. An improved version with afterburning engines began production in 1984 and is designated J-22(M) or Orao 2, with production totalling 165 in both countries.
