| The first of the "A" high-altitude fighter series to mate
turbo-supercharger and cabin pressurisation, the I-222,
or 3A, was powered by a Mikulin AM-39B-1 engine
which afforded 1750hp for take-off and had a TK-300B
turbo-supercharger on its port side. Armament consisted
of two synchronised 20mm ShVAK cannon. Reverting
to the wooden monocoque rear fuselage of the
I-220, the I-222 employed a Shchyerbakov-designed
pressure cabin of welded dural sheet with inflatable
rubber seals and pressurized by air tapped from the
compressor. The cockpit was air conditioned for the
first time in a Soviet fighter. The flight test programme
began on 7 May 1944, but although plans had been formulated
to produce the "A" series altitude fighters in
quantity, the course of the war had meanwhile virtually
eliminated the threat of high-altitude Luftwaffe attack. Priorities were therefore changed and although the development
programme was continued all proposals for
series production were discarded.
