context_page_description: The Junkers J.I was a German "J-class" armored sesquiplane of World War I, developed for low-level ground attack, observation and army cooperation. It is especially noteworthy as being the first all-metal aircraft to enter mass production; the aircraft's metal construction and heavy armour was an effective shield against small arms fire over the battlefield.
