It is difficult to imagine two front-line fighters of Soviet-made fighter jets that could confront each other in a battle. Actually, That happened in the skies of Africa.
For many years, the two fourth-generation fighters, the MiG-29 and the Su-27, were the backbone of the Soviet and Russian Air Forces. The MiG-29 (Fulcrum) light tactical fighter is used to gain direct superiority in the sky in the combat area, while the Su-27 (Flanker-B) supersonic heavy fighter is capable of hitting enemy aircraft from long distances.
With different missions, these two types of aircraft often support each other in skirmishes and only compete in combat training. However, in 1999, during the armed conflict between Ethiopia and Eritrea, the Su-27 and MiG-29 faced each other in a life-and-death battle.
