I-225, '5A' A.I.Mikoyan/M.I.Gurevich

28k b/w drawing of I-222, I-224 and I-225 at "History of aircraft construction in the USSR", Vol.1 p.239;

I-225 concluded line of A.I.Mikoyan-and-M.I.Gurevich piston engine high altitude interceptors. Even more powerful engine, even more powerful armament (salvo 5.12kg/sec) ... but too late to go to series production. Jet engines could provide higher speeds and altitudes, unreachable with piston engines.

First flight (pilot A.P.Yakimov) took place on May 21, 1944. On August 7, 1944 at 7800m speed 704km/h was demonstrated. Tests were not finished due to crash in 15th flight.

Second I-225 with AM-42FB engine and improved pilot view was flown only on March 14, 1945.

Predecessor I-224, 4A
Development None. It was time to go jets.
