MiG-5 (IT, DIS-200)

Long Range Fighter (prototype)

Mikoyan, Gurevich

DIS-200 with M-82F

It was originally intended to power the second DIS prototype with M-40 diesel engines offering 1.500 hp each. Diesels would theoretically provide the DIS with a longer range than gasoline powered engines, due to their low fuel consumption, but the M-40 had a number of problems that delayed its development. For this reason, the second DIS prototype was equipped with two ASh-82 fourteen-cylinder two-row radial engines of 1,676 hp each.

This second prototype received the MiG Design Bureau designation 'IT' and the military designation DIS-200. The public designation 'MiG-5' was carried over from the first DIS.

Adoption of radial engines led to a redesign of the engine nacelles. In contrast to the DIS, the main wheel cover doors were enlarged and bulged. The DIS-200 was equipped with Hucks-type starter lugs on the propeller spinners.

Work on the DIS-200 started at Moscow-Khodinka. but when the State Aircraft Factory had to be evacuated, the unfinished DIS-200 was taken east to Kuibyshev. The DIS-200 took off for its maiden flight on 22 January 1942. The factory test program of the DIS-200 at Kazan came quickly to an end in 1942, when combat experience on the Eastern Front showed that there was no need for a long - range escort fighter. Most escort missions required for the Pe-2 and DB-3 bombers were of short duration and could be performed by the existing single-engine Lavochkin and Yakovlev fighters.
