The Mikoyan-Gurevich I-211 was a prototype high-altitude Soviet fighter aircraft built during World War II.

[1] Artem Mikoyan and Mikhail Gurevich continued development and another prototype was built, the MiG I-211, or the MiG-9Ye, using the improved ASh-82F engine.

By this time there was little demand for a high-altitude fighter and the project was canceled with only a single aircraft built.

The acronym DIS comes from Dalnij Istrebitel Soprovozhdenya or long-range escort fighter.
