Junkers J.I Country: Germany Type: Ground attack Manufacturer: Junkers Service: 1917 - 1918 First Flight: 1917 Production: 227

The Junkers J.I was a German sesquiplane format warplane of World War I, developed for low-level observation and ground attack. It is especially noteworthy as being the first all-metal aircraft to enter mass production. It was a slow aircraft, but its metal construction and heavy armour, which comprised an extremely advanced, single-unit armored structure that ran from just behind the propeller, to the rear crew position, and acted both as the main fuselage structure and engine mounting setup in one unit, was an effective shield against anti-aircraft defensive fire.
