Junkers J.I / J.4

The Junkers J.I (manufacturer’s name J 4) was a German “J-class” armoured 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.
