The Polikarpov I-15 "Seagull" (Russian: И-15 "Чайка") was a Soviet fighter aircraft that first flew in October 1933 with V.P. Chkalov at the controls.
The design for the 14th fighter for the VVS, the I-14, started as an advanced (for the era) monoplane under the direction of Andrei Tupolev. He grew concerned that the design would not mature, and orded up two backup biplane designs as the I-14A and B just to be safe. Polikarpov had just been released from prison in August 1932, and was handed the I-14A project. When both the I-14 and I-14A were ordered into production, Polikarpov's design became the famous I-15.
I-15, also known by its development name TsKB-3, a small biplane fighter with a gulled upper wing. It was a development of the I-5 fighter.
The I-15 was used in combat in the Spanish Civil War and proved to be one of the best fighter biplanes of its time.
It was equipped with one 700 PS (515 kW) M-25 engine. Total 674 were built.
