The Polikarpov I-15 was a soviet series of single engine biplanes that entered service in 1934. These fighters had a number of technical solutions that could not be considered innovative by the middle and the end 1930s, like mixed wood and metal construction with fabric covered elements, non-retractable landing gear and an open cockpit. These features directly impacted the aircraft’s speed, but gave the I-15 its biggest advantage - outstanding manoeuvrability. Moreover, the fighter’s considerable armament (4x7.62 caliber machine guns) and good climb rate allowed its use as a high-altitude interceptor.
The I-15’s contemporary a Japanese fighter the Ki-10 had been created under the direction of Kawasaki’s engineer and aeronautical designer Takeo Doi. The model was the last biplane adopted by the Japanese Army and possessed relatively good speed (for a plane with fixed landing gear) and high manoeuvrability. However its armament was inadequate by all standards, consisting of just two 7.7mm machine guns.
In 1939 the Japanese and Soviet biplanes faced each other in the battles over the Mongolian river of Khalkhin Gol (the events also known as the Nomonhan Incident). The undeclared war broke out between the USSR, Mongolia, the Japanese Empire and its puppet state of Manchukuo. It was fought from May till September of 1939 and ended up in a Japanese army defeat. By that time both the Polikarpov I-15 (in its ‘bis’ modification) and the Kawasaki Ki-10 II were near obsolete and suffered heavy losses from modern monoplanes like Ki-27 and I-16.
