Historical information
The Polikarpov I-3 was a soviet fighter designed during the late 1920s. It entered service in 1929, but was retired in 1935 with the advent of fighters with higher performance.
The first prototype was completed in early 1928 and made its first flight on 21 February. A second prototype was completed in August 1928 and tested a different propeller optimized for high speed which increased the top speed to 283 km/h (176 mph), although it lengthened the take-off run. The first 39 aircraft completed, plus the two prototypes, used imported engines, but the remainder used the license-built Mikulin M-17.
Approximately 400 were built, with Gordon and Dexter citing sources that state 389 or 399.
