The best possible results with MiG-3 airframe were achieved when the I-231 rolled out. But it was not enough to make a decision in favor of mass production. Progress of advanced high altitude fighter required to change the size of aircraft.

It was done in 1944, when the I-220 was built in two configuration - with AM-38F and AM-29 engines. Several novel construction elements were introduced: tunnel radiators inside of the wing, soft fuel tanks, lever wheel suspension. Armament was formidable - four 20mm ShVAK cannons (reload powered by engine exhaust gases), two of them could be easily removed for low-weight operation.

I-220 with AM-38F was tested in January 1944, and later re-engined with AM-39. The AM-38F engine was more suitable for low-level ground attacker, and high altitude performance was not that superior.

The second I-220 (with AM-39) was factory tested in July-August 1943 and came to the State Trials on June 14, 1944. Good high altitude performance was demonstrated, but tests were interrupted on June 21 when engine gave up.
