The Soko G-4 Super Galeb (Super Seagull) is a single engine, advanced jet trainer and light ground-attack aircraft.

Design and development

First flown on 17 July 1978, with serial production beginning in 1982, the G-4 was designed to replace the G-2 Galeb in the Yugoslav Air Force.

Operational history

The G-4 saw some combat during the Yugoslav Wars. In total, three G-4s were shot down, all pilots ejecting safely.

During the Kosovo War, the G-4 was used in several combat sorties against KLA positions. Seven G-4s of the Leteće Zvezde aerobatics team were destroyed at Golubovci Airbase, as a result of a NATO airstrike.^{[citation needed]}

Only two G-4s have been involved in fatal accidents in its 27 years of service; the latest involved a Serbian G-4 Super Galeb which crashed at Batajnica Air Base near Belgrade on 24 September 2008 while practicing for an upcoming air show.
