Messerschmitt ME 262A-2A "Sturmvogel"

The German Me-262 was the first operational jet powered fighter aircraft and the only jet fighter to see active air to air combat in WWII. Initial design work for the Me-262 began in 1938 although problems with the turbojet engines delayed its maiden flight until 1942. The 262 entered service in 1944 in both the fighter and fighter bomber role. A shortage of supplies meant the 262's true potential was never realised.
