The Soko J-21 Jastreb was a single-seat attack/reconnaissance aircraft designed in Yugoslavia in the 1960s. It is closely related to the similar 2-seat G-2 Galeb. The aircraft were built by SOKO, in Mostar (present-day Bosnia and Herzegovina), until the 1980s. They were used by the SFR Yugoslav Air Force until its demise in 1991; remaining aircraft were passed on to the newer air forces of the Republika Srpska Air Force and the Air Force of the Federal Republic of Yugoslavia / Serbia and Montenegro.

ervice History

"See also Banja Luka incident"

When they were first designed in the 1960s, they were primarily used by the SFR Yugoslav Air Force as a trainer jet, although they were combat capable due to the J-21 being an attack aircraft. The J-21 was also used as a reconnaissance/spy jet in the former Yugoslav Air Force. After the break up of the SFRJ, many J-21s were passed onto the Republika Srpska and the Federal Republic of Yugoslavia, in which some were deployed in combat in the Yugoslav Wars from 1991-1995.

In the early years of the Yugoslav Wars, especially in Bosnia and Herzegovina, the J-21 Jastreb was used by the Republika Srpska Air Force, which were being challenged by NATO fighter jets in Bosnian airspace.

After the Dayton Peace Accords were signed in 1995, the war in the Former Yugoslav territories ended, and the J-21s were no longer used in combat. As a part of a SALT (Strategic Arms Limitation Treaty), the Federal Republic of Yugoslavia withdrew its remaining 66 J-21 Jastreb aircraft from service.Fact|date=September 2007
