I believe that this is the airborne command post version of the Mi-6, hence all of the antennas depicted on the schematic. (https://en.m.wikipedia.org/wiki/Mil_Mi-6)
There was also a different project titled Mi-22, but was more of a troop carrier in the same vein as the UH-1. (https://www.aviastar.org/helicopters_eng/mi-22.php)
