In May 1971 'JUROM' agreement was signed by Yugoslavia and Romania to jointly build a light subsonic ground attack and reconnaissance aircraft for their respective air forces. In Yugoslavia the resultant aircraft was the Soko J-22 Orao and in Romania it was known as the IAR-93. The Rolls-Royce Viper engine was chosen for the powerplant as Soko had previously built it under license. The first flight of the IAR-93 was on October 31, 1974 from Bacau. Avioane Craiova SA as it is now known, was established in 1972 and started full production at its Craiova factory from 1975. The two-seat IAR-93DC first flew on January 23, 1977 but was lost due to tail flutter ten months later. The IAR-93A eventually entered service in 1981.
There were four prototypes, two IAR-93As (serials 001 and 004) and two IAR-93DC (002 and 003) two-seat trainers. The first prototype (001) was lost in September 1979 falling an engine flame out.
26 IAR-93As (109-119 and 150-164) and nine IAR-93DCs (005-008 and 180-184) supplied with non-afterburning Viper 632 turbojets.
15 single seat IAR-93MB (201-215) with basic Viper 632 engine (Motor de Baza) but with an IAR-93B airframe. Deliveries of the MB version started in 1982.
The IAR-93B with its recently developed after-burning Viper 633 engine entered service in 1987. 27 IAR-93Bs (200 the prototype and 216-241) were built as single seats with another six two-seat DC versions (600-605).
By 1989 the 67th Fighter-Bomber Regiment (Grupul 67 Aviatie de Vânâtoare-Bombardament) and its two squadrons were flying the IAR-93 at Craiova. The 49th Fighter-Bomber Regiment at Lanca also had a squadron of IAR-93. In 1992 with a number of incomplete aircraft for an outstanding order for Yugoslavia, civil war started in Yugoslavia. A subsequent UN embargo on arms sales effectively ended production of the IAR-93. The Romanian Government made the decision to retire the IAR-93 in 1998 after persistent problems and many of the surviving aircraft moved to the 322 Aviation Maintenance Centre (Centrul de Mentenanta 322 Aviatie)
at Craiova. The engines and control systems were removed and they were placed in open storage.
Avioane Craiova SA is currently producing the IAR-99 Soim at Craiova.
