History Aeronautical Institute Soko J-21 Jastreb 'hawk'
The Soko J-21 Jastreb (from Serbian Cyrillic: јастреб, lit. 'hawk'), referred to as the J-1 Jastreb in some sources, is a Yugoslav single-seat, single-engine, light attack aircraft, designed by the Aeronautical Technical Institute (ATI) and Military Technical Institute (VTI), in Belgrade and manufactured by SOKO in Mostar. Derived from the G-2 Galeb advanced jet trainer and light attack aircraft, it was designed in single-seat ground-attack and two-seat advanced flying/weapon training versions.
Design
The J-21 Jastreb was developed as a replacement for the Republic F-84 Thunderjet, which had been the most commonly used turbojet fighter-bomber aircraft of the Yugoslav Air Force until 1967. On the basis of the G-2 Galeb, the J-21 Jastreb was developed as a single seat ground attack variant, flying for the first time on 19 July 1965.
Pilots sit on licence-built Folland Type 1-B ejection seats under individual canopies hinged on the starboard side in un-pressurised cockpits. Instruments and controls are entirely conventional with manually operated flying controls and standard flight instruments.
Operational history
First Congo War
According to some reports, France and Yugoslavia supported Mobutu's government during the First Congo War.[] Namely, Yugoslavia agreed to deliver three J-21 and a single G-2 aircraft, as well as four MiG-21PFMs, while three Mi-24s were purchased from Ukraine. All these aircraft were based at Gbadolite and flown mainly by Serbian mercenaries.
