Arado AR-234B

The Arado Ar 234 Blitz (English: lightning) was the world's first operational jet-powered bomber, built by the German Arado company during World War II.

The cockpit was at the front of the fuselage, and the pilot had no direct view to the rear, so the rear firing guns were aimed through a periscope, (derived from the type used on tanks) mounted on the cockpit roof. The defensive fixed rear gun system intended for the prototype series was generally considered useless[by whom?] and was omitted in the Ar 234B, which retained the periscope. The B version also had fully retractable tricycle landing gear, which retracted forward into the mid-fuselage; the nosegear retracted rearwards.

Produced in limited numbers it was used almost entirely for aerial reconnaissance. It was the last Luftwaffe aircraft to fly over the UK during the war, in April 1945.
