The Junkers J.I (manufacturer's designation J4, not to be confused with the earlier, pioneering Junkers J 1 all-metal monoplane of 1915/16) 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 "bathtub" 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.

Development

pioneering all-metal monoplane prototype began at Dessau and at the beginning of December 1915 the first Junkers aircraft was finished.

The armored "bathtub" concept of the J.I, because Hugo Junkers had to move his aircraft manufacturing equipment out of Germany into the Moscow suburb of Fili in the Soviet Union during the 1920s, could have been noticed by Sergei Ilyushin and remembered by him, when his design bureau worked on the similarly-equipped Ilyushin Il-2 "Shturmovik" Soviet ground attack aircraft of World War II.

Operational history

It was well-liked by its crews, although its ponderous performance earned it the nickname "Furniture Van". They were used on the Western Front during the Kaiserschlacht of March 1918. There were 227 J.Is manufactured during the war.
