Picture from "History of aircraft construction in the USSR", Vol.1 p.175

Probably the best domestic WWI fighter design in Russia. It was faster than any contemporary fighter except 'Vickers'.

Five built in September 1916, and were not noticed by military command...

Float plane version (1917) was not finished.
