The Yugoslav Institute of Aviation Technology started to develop the first jet from 1957.

The Yugoslavs wisely chose their own direction: designing a light trainer.

From the design point of view, the first generation of Yugoslav jet aircraft is quite conservative, the airfoil and layout of straight wings are simple, and the fuselage is almost straight. This shape is doomed to its poor flight performance. This is indeed the case: although the aircraft adopts the "Viper 2/22-6" turbojet engine provided by rolls royce Company in the UK, the thrust reaches 1 1. 12 kn, which is more advanced than the Soviet engine widely used in Eastern European countries at that time, and the ejection seat also adopts the British product: Fran-/kloc-. However, the maximum speed of the plane is only 8 12 km/h, and the Yugoslavs named their first jet plane "Seagull" with the model of G-2. 196 1 may test, and put into production two years later.

During the Kosovo War, American F 16 shot down four seagulls at a time with AIM 120, and made a good advertisement for AIM 120.
