The Arado Ar 234 was the world's first operational jet powered bomber, built by the German Arado company in the closing stages of World War II. In the field it was used almost entirely in the reconnaissance role, but in its few uses as a bomber it proved to be nearly impossible to intercept. Twin-engined and single seater, was produced in limited numbers. It was the last Luftwaffe plane to fly over England, in April 1945. 
It is commonly known as Blitz ("lightning"), though this name refers only to the B-2 bomber variant, and it is not clear whether it was ever formally applied instead of being derived from the informal term Blitz-Bomber (roughly, "very fast bomber"). The alternate name Hecht ("pike") is derived from one of the units equipped with this plane, Sonderkommando Hecht. The Ar 234 (and the Messerschmitt Me 262) showed in which direction plane technique should develop. .
