Tupolev I-8

Tupolev I-8 (also known as ANT-13) was an experimental interceptor built in the Soviet Union in the early 1930s. It was the first Soviet aircraft to exceed 300 km/h (162 knots, 186 mph) in level flight. The aircraft was an exercise in developing the Polikarpov I-5 design by a group of engineers led by V. M. Rodionov each of whom volunteered 70 hours of personal time to the project.
