High Quality Content by WIKIPEDIA articles! The Polikarpov I-185 was a Soviet fighter aircraft designed in 1940. It was flown with three different engines, but all of them were either insufficiently developed for service use or their full production was reserved for other fighters already in production. The I-185 program was cancelled after a yet another engine failure of the favored 2,000-horsepower (1,500 kW) Shvetsov M-71 radial on 27 January 1943.
