The Mikoyan-Gurevich DIS (Russian: Дальний истребитель сопровождения - "long-range escort fighter") was a prototype Soviet fighter aircraft of World War II. It was also intended to develop reconnaissance and bomber versions, but these plans never materialised. The MiG DIS was a sleek, twin-engined, twin-tailed machine of mixed construction. Only two examples were built.
The first, developed under the bureau designation T, was powered by Mikulin AM-37 engines. It first flew in late 1941 and performed well in flight tests. The second machine, the IT, had Shvetsov M-82F engines and was completed in October the following year but did not complete flight testing before the project was cancelled. Despite the promise shown by the type, the NKAP felt that the aircraft's capabities and performance were too similar to those of the Petlyakov Pe-2, which was already in production.
The service designation MiG-5 had been reserved for this aircraft but in the end was never used. The same designation is sometimes erroneously applied to the Mikoyan-Gurevich I-211, a completely unrelated prototype aircraft based on the MiG-3.
