Several years before World War II, the Germans foresaw the great potential for aircraft that used the jet engine, constructed by Hans Joachim Pabst von Ohain in 1936. After the successful test flights of the first jet of the world, the Heinkel He 178, they adopted the jet engine for an advanced fighter aircraft. As a result, the Me 262 was already under development as Projekt 1065 (P.1065) before the start of World War II.
