During the Great Patriotic War N.N.Polikarpov made an effort to design a fighter with performance even with best contemporary machines, but with superior firepower. He chose liquid-cooling engines of new design from both V.Ya.Klimov and A.A.Mikulin, promising high power output.
Airframe of the ITP was similar to I-185. Wooden monocoque fuselage made of multi-layer birch ply was combined with duralumin wing (main spar had steel shelves), controls - with fabric cover. Oil cooler located in 'chin' position. Water cooler - in the wing, with intakes on the leading edge. Heavy Sh-37 cannon fired through the propeller hub, pair of synchronized ShVAK cannons were also housed under the engine cowling.
Jean Alexander notices 'strange reminiscence' between the ITP and Mikoyan-Gurevich MiG-1/MiG-3. Actually this is not a surprise, because both designs are rooted in the N.N.Polikarpov 'Kh' (Cyrillic 'X') project of high-altitude interceptor.
Aircraft was built in late 1942, but flew first time only on November 23, 1943. Factory trials continued until June 1944. Abandoned after N.N.Polikarpov death, because A.S.Yakovlev had already adapted the Yak-9 to carry the 37mm cannon.
