The AEG C.V was a prototype two-seat biplane reconnaissance aircraft of World War I. Designed to use a more powerful engine than previous AEG C-class reconnaissance aircraft, results were disappointing enough that further development was cancelled.
The AEG C.VII was a prototype two-seat biplane reconnaissance aircraft of World War I. It was developed from the C.IV but did not enter production. The C.VII was tested with two different wing arrangements, one with slightly tapered single bay wings and another with sharply swept upper wing.
The AEG D.I was a biplane fighter of World War I. Three prototypes were ordered, but after the first two were involved in serious crashes, one of which killed flying ace Walter Höhndorf on September 5, 1917, development was cancelled. A triplane version was built as the Dr.I. The second and third prototypes differed little from the first except in detail.
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.
The AEG G.IV was a biplane bomber aircraft designed and produced by the German aircraft manufacturer Allgemeine Elektrizitäts-Gesellschaft. It saw action during the First World War with the Luftstreitkräfte.
The AEG G.V was a biplane bomber aircraft of World War I, a further refinement of the AEG G.IV. The type saw limited production before the Armistice, and never entered operational service. It featured a 600 kg (1,320 lb) bombload.
The AEG J.I was a German biplane ground attack aircraft designed and produced by the German aircraft manufacturer Allgemeine Elektrizitäts-Gesellschaft. It was a mission-specific derivative of the AEG C.IV reconnaissance aircraft.
The AEG PE was a triplane ground-attack aircraft of World War I, one of the first aircraft designed from the outset for that role. The Idflieg rejected it on the grounds that its poor maneuverability made it too vulnerable to enemy fighters.
The Pfalz D.VIII was a German World War I fighter aircraft.
The Friedrichshafen FF.31 was a two-seat prototype German maritime reconnaissance floatplane built by Flugzeugbau Friedrichshafen during the First World War. Although primarily intended for reconnaissance duties, the aircraft was provided with a machine gun to engage other aircraft. Although it was satisfactory for its intended mission, it lacked the performance necessary for use as a fighter. A pair of aircraft were built in 1915 and it was not accepted for production by the Imperial German Navy's Naval Air Service.
The DFW R.I,, was a prototype German bomber aircraft of World War I.
The Gotha G.VII was a bomber aircraft produced in Germany during the final months of World War I. With the strategic bombing campaign effectively over, it was intended to be a high-speed tactical bomber with a secondary reconnaissance capability.
The Gotha WD.14, WD.20, and WD.22 were a family of biplane torpedo bomber floatplanes developed in Germany during World War I.
The Albatros B.III,, was a German World War I reconnaissance biplane, built by Albatros Flugzeugwerke as the Albatros LDD.
The LVG G.III was a large, twin engine triplane bomber built in Germany near the end of World War I. Only one was completed.
The Halberstadt G.I was a German prototype heavy bomber built by Halberstädter Flugzeugwerke during World War I.
The Aviatik C.VIII was a prototype German observation aircraft built by Aviatik in World War I.
The Germania C.I was a prototype two-seat general-purpose biplane built by Halberstadt during World War I.
The Halberstadt C.VIII was a prototype two-seat general-purpose biplane built by Halberstadt during World War I.
The LVG C.VIII was a prototype reconnaissance aircraft built in Germany during World War I.
