Focke-Wulf Fw 190 D of Jagdverband 44.
The 190 Doras of the Platzschutzschwarm were tasked with protecting the units' Me 262s during takeoff and landing.
In order to avoid friendly fire by own AAA, the Fw 190 were painted with a highly visible colour scheme on their underside, which earned them the nickname "Papageienstaffel" ("parrot squadron").
The "Rote 1" depicted in my drawing was flown by Heinz Sachsenberg, who claimed 104 aerial victories.
Note that my depiction of the scheme is probably not super accurate, but its all I managed to come up with.
