According to Herbert Leonard's Docavia great book, the I-188 was a pure interceptor project, with 2 versions:
- 1 looking like the I-187 with a total vision canopy and either a M-90 engine (2,080hp) or else its derivative M-95 (3,300hp for reaching 800km/h speed).
- 1 looking like the I-185/M-71 with a "faired" (?) canopy but with a M-90 engine.
Both were cancelled in February 1943 (together with I-185 and I-187) under Yakovlev pressure.

M-90 versus M-95 comparative drawings

Dear Justo! This "I-188 M-95" drawing is a What-if, nothing more. And it even isn't very well-done. The M-95 engine (existing only as a project, with 3300 hp estimated power) was 27-cylinder 3-row radial, indeed a M-90 with additional third row. You understand that it would weigh about 1.5x more than original M-90, and it's absolutely impossible to replace the last with M-95 without lengthening the fuselage and/or other major changes, keeping the center of gravity in acceptable position. Also, if the wing would remain, the wing loading would achieve terrible 300 kg/m2 or even more... Absolutely unpractical. Only as a racer / speed record breaker, maybe.

Topic split from the Polikarpov projects thread.

I'm reattaching here a plan of the I-187-M-71 project from Krylia Rodine, August 1990:
