The Russian air-force has begun the introduction of a new, bluish dark grey color scheme for it’s aircraft. The first examples of this paint scheme were used on brand new Mi-26T2 helicopters. Recently, new production Mi-28 combat helicopters were shown with the new paint scheme. There is also a rumor that new Su-34 strike aircraft will receive the dark grey as paint, as well.
