Tu2 "4 White", 1st AE. Spring 1945.
Its difficult to find a unusual skin from the Russian Airforce. Thanks to Lyric1 for finding me the info for this skin.
In late 1944 the Soviet Air Force had altready reached a position of superiority over the German Luftwaffe and its alleys. While Germans reverted to green/brown camouflages to hide better their planes on the ground, the Soviets decided to extend to all planes the blue grey/dark grey camouflage that has been successful for fighters since August 1943.
On October 1, 1944, the Resolution n.6339 was approved, but burocratic delays retarded its publication till January 1945.
It took time to trickle down to the units, and it wasn't always followed. However "4 white" was one that did.
