AEG Dr.I

The AEG Dr.I was a prototype triplane fighter built by AEG in 1917 for the Imperial German Air Service, derived from the D.I biplane. German pilots had been impressed by the British Sopwith Triplane, and in July 1917 the Inspectorate of Flying Troops ordered triplanes from almost every German maker. AEG fitted a D.I with new three-level wings and completed one prototype in October, keeping the same fuselage, 120 kilowatt Mercedes engine and twin machine guns. It reached 200 kilometres per hour, but the single aircraft was not chosen for production.
