The AEG C.VIII was a prototype two-seat reconnaissance aircraft of World War I. Two examples were built, based on the successful C.IV design, one of biplane configuration, the other a triplane. Neither version offered enough of an improvement on the C.IV to make mass production worthwhile.
The AEG G.I was a three-seat, twin-engined German biplane bomber aircraft of World War I. It was tested and found to be viable for air-fighting in the latter half of 1915 but performed poorly, necessitating the development of the AEG G.II.
The AEG G.II was a German biplane bomber aircraft of World War I developed from the AEG G.I, with more powerful engines. The G.II was typically armed with three 7.92 mm (.312 in) machine guns and 200 kg (440 lb) of bombs. The bomber suffered stability problems, and many G.IIs were fitted with additional vertical tail surfaces on each side of the fin and rudder to improve flight handling characteristics.
The AEG G.III was a German biplane bomber aircraft of World War I developed from the G.II. Like its predecessor, it was only built in small numbers and saw limited operational use, mainly far from the main fronts of the war.
The Aviatik C.I was an observation aircraft which came into service during World War I in April 1915. It was a development of the Aviatik B.I and B.II models, being one of first aircraft of the new German C class of armed biplanes. In the C.I the observer sat in front of the pilot, with a machine-gun clipped on a sliding mounting fitted on a rail at either side of the cockpit. It gave the crew the means to attack enemy aircraft. The positions of the pilot and observer were reversed in last series of 50, ordered in 1917 solely for trainer purpose. There was only one aircraft built of refined C.Ia version in May 1916, with armament still in a forward cab, serving as a prototype for C.III. Later models of the plane included the Aviatik C.II and the C.III, which had more powerful engines. The C.III was produced in large numbers.
The Zeppelin-Staaken R.VI was a four-engined German biplane strategic bomber of World War I, and the only Riesenflugzeug design built in any quantity.
The Friedrichshafen G.III was a heavy bomber designed and manufactured by Flugzeugbau Friedrichshafen. They were used by the German Imperial Air Service during World War I for tactical and limited strategic bombing operations. After the end of the war a number of Friedrichshafen bombers were converted into transport aircraft while a small number also saw service as dedicated airliners.
The Friedrichshafen G.II was a heavy bomber aircraft that was designed and manufactured in Germany during World War I by Flugzeugbau Friedrichshafen. The plane was used by the Luftstreitkräfte for tactical and limited strategic bombing operations.
The Friedrichshafen G.IV and G.V respectively were heavy bombers that were designed and manufactured in Germany during World War I by Flugzeugbau Friedrichshafen. The G.IV saw limited use by the Luftstreitkräfte for tactical and limited strategic bombing operations, while the G.V and a follow-on design, the FF.62 did not fly until after the Armistice.
The Gotha G.II series was a heavy bomber used by the Luftstreitkräfte during World War I.
The Rumpler C.IV was a German single-engine, two-seat reconnaissance biplane. It was a development of C.III with different tail surfaces and using a Mercedes D.IVa engine in place of the C.III's Benz Bz.IV. The Rumpler 6B 2 was a single-seat floatplane fighter variant with a 120 kW (160 hp) Mercedes D.III engine built for the Kaiserliche Marine.
The Hannover CL.II was an escort fighter, produced in Germany during World War I, designed in response to a 1917 requirement by the Idflieg for such a machine to protect reconnaissance aircraft over enemy territory. It was a compact biplane of largely conventional configuration with single-bay staggered wings of unequal span. The fuselage was a thin plywood paneled, wooden monocoque design, very similar to the style of fuselage in Robert Thelen's Albatros series of single-seat fighters.
The Siebel Fh 104 Hallore was a small German twin-engined transport, communications and liaison aircraft built by Siebel.
The Siemens-Schuckert R.VIII was a bomber aircraft designed and built in Germany from 1916.
The Albatros C.II was a 1910s German military pusher reconnaissance biplane designed and built by Albatros Flugzeugwerke. Only one aircraft was built and the type did not enter production.
The Zeppelin D.I, or Zeppelin-Lindau D.I or Zeppelin D.I (Do), as named in German documents, also sometimes referred to postwar as the Dornier D.I or Dornier-Zeppelin D.I, for the designer, was a single-seat all-metal stressed skin monocoque cantilever-wing biplane fighter, developed by Claude Dornier while working for Luftschiffbau Zeppelin at their Lindau facility. It was too late to see operational service with the German Air Force (Luftstreitkräfte) during World War I.
The Zeppelin-Lindau Rs.IV was a Riesenflugzeug monoplane all metal flying boat with a stressed skin hull an fuselage developed for the Imperial German Navy to perform long range patrols over the North Sea. It had been developed by Claudius Dornier while working for Zeppelin in the town of Lindau.
The Zeppelin-Lindau CS.I was a German single-engined reconnaissance seaplane with a low-wing monoplane layout.
The Halberstadt G.I was a German prototype heavy bomber built by Halberstädter Flugzeugwerke during World War I.
The Halberstadt C.VIII was a prototype two-seat general-purpose biplane built by Halberstadt during World War I.
