The Junkers J.I (manufacturer's designation J 4, not to be confused with the earlier, pioneering J 1 all-metal monoplane of 1915/16) was a German "J-class" armored sesquiplane format warplane of World War I, developed for low-level observation and Army cooperation. 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 armoured "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 artillery.

The experimental developments were interrupted by the breakout of World War I in August 1914. In May 1915, Junkers achieved a test order for the further development of his all-metal aircraft by the German War Ministry, when delegates of this Ministry visited the Dessau "Jco" (Junkers Company) plants. In September 1915, the production of the J 1 pioneering all-metal monoplane prototype began at Dessau, and at the beginning of December 1915, the first Junkers aircraft was finished.

Operational history

It was well-liked by its crews, although its ponderous performance earned it the nickname "Furniture Van". The aircraft first entered front service in August 1917. They were used on the Western Front during the Kaiserschlacht {Kaiser's Battle} of March 1918. The production at Junkers works was quite slow due to poor organization and monthly output was low. There were only 227 J.Is manufactured until the production cease in January 1919 (part of them, after hostilities). Although a number were lost primarily to landing accidents, none were apparently lost in combat, a tribute to its tough armoured design.


German Empire



Only one relatively complete aircraft survived, bearing German military serial number J.I 586/17 and preserved at the Canada Aviation Museum in Ottawa. Two fuselages exist, one at the Science & Technology National Museum in Milan, Italy, and another at the Deutsches Technikmuseum Berlin.
