Ilyushin Il-2

The Ilyushin Il-2 was a ground-attack aircraft (Shturmovik) in the Second World War, produced by the Soviet Union in very large numbers. In combination with its successor, the Ilyushin Il-10, a total of 42,330 were built, making it the single most produced military aircraft design in all of aviation history, as well as one of the most produced piloted aircraft in history along with the Cessna 172 and the Polikarpov Po-2. It is regarded as the best ground attack aircraft of World War II. It was a prominent aircraft for tank killing with its accuracy in dive bombing and its 37mm guns being able to penetrate tanks' thin back armour.

When the Race invaded in mid 1942, the Soviet Air Force had been using the Stormovik to great effect. When Heinrich Jager first encountered a Race Killercraft, he mistakenly though he was under attack from the Russian plane.
