The AEG Dr.I was a triplane fighter of World War I, based on the D.I. Only a single prototype was built and its poor performance meant that no production ensued. The Dr.I was a Dreidecker (triplane) variant of the D.I and had been inspired by a Sopwith Triplane that had been captured intact. A number of proposals for fighters with comparable characteristics were put forward, and AEG's contribution to the program appeared in October 1917. Other than the triple wing it was a D.I, the aircraft had the same fuselage, engine and twin gun armament of its earlier brethren.
