Me 262

The Me 262 represented a quantum leap in fighter design. Its twin Junkers Jumo 004 turbojet engines gave it a 100 mph speed advantage over the best Allied piston fighters. The aircraft could have entered service earlier, but Hitler's insistence on using it as a bomber delayed its deployment. When it finally appeared in numbers in late 1944, Allied pilots were shocked by its speed. The Me 262 shot down over 500 Allied aircraft, including numerous heavy bombers. However, its engines were unreliable (lasting only 25 hours), it was vulnerable during takeoff and landing, and Allied fighters learned to attack it on approach. Despite these limitations, the Me 262 proved that the future of air combat belonged to jet propulsion, accelerating jet fighter development in every major air force.
