Den Polikarpov I-153 Chaika (russisk Чайка, «Måke») var et sovjetisk biplanjagerfly på slutten av 1930-tallet. I-153 ble utviklet som en avansert versjon av I-15 med et uttrekkbart understell, og kjempet i de sovjetisk-japanske kampene i Mongolia og var en av Sovjets viktigste jagerflytyper i de første årene av andre verdenskrig. Tre I-153 flyr fortsatt.

General Characteristics and Role

The Polikarpov I-153 Chaika (Russian for “Seagull”) was the final evolution in a line of highly maneuverable Soviet biplane fighters. It was developed in the late 1930s to combine the agility of its predecessor, the I-15, with increased speed and performance. Key features included a manually retractable landing gear to reduce drag, a gull-wing upper wing design (giving it the nickname Chaika), and improved armament. Although it was the fastest biplane ever to see operational service and performed well in early conflicts, it was rapidly made obsolete by the advent of faster monoplane fighters, such as those of the German Luftwaffe, by the time of the German invasion in 1941.
