The Gotha G.IV is a German, two-engine, two-plane heavy bomber of a mixed construction from the First World War period with a crew of three. The "fathers" of the aircraft were engineers Oskar Ursinus and Helmut Friedel, and the G.IV aircraft was created as a result of an order by the German aviation for a heavy bomber plane. The flight of the prototype, very much modeled on the Friedrichshafen G.III plane, took place in 1916 and at the end of that year it entered linear units. The first combat use of the new machine took place in February 1917, during an air raid over England. In the same year, they also took part in Operation Türkenkreuz - a strategic bombing of London. In 1918, planes also bombed London and Paris. During the war, 230 copies were produced.
