The Petlyakov Pe-2 (Cyrillic: ???????? ??-2), nicknamed Peshka (????? - "Pawn") was a Soviet dive bomber aircraft used during World War II. It was fast and maneuverable yet durable, and was manufactured in large numbers. Several Communist nations flew the type after the war, when it became known by the NATO reporting name Buck. The Finnish Air Force serial code was PE- and unofficial nickname Pekka-Eemeli.
