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 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 AGO C.II was a German reconnaissance biplane of World War I. It was essentially a slightly redesigned version of the manufacturer's C.I design with a more powerful engine and 3-bay wings.
The Friedrichshafen G.I was a prototype heavy bomber aircraft that was built in Germany by Flugzeugbau Friedrichshafen in 1915. It was Karl Gehlen's first design for the company, and although it was not produced in quantity, it provided the foundation for the later, highly successful bombers culminating in the G.III.
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 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 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 Daimler D.I was a German fighter aircraft of World War I. It was a conventional biplane design with a very small interplane gap - the top wing nearly touched the top of the fuselage. Power was provided by a Daimler D.IIIb water-cooled V-8 engine.
The Zeppelin-Lindau Rs.I was a large three-engined biplane flying boat designed by Claudius Dornier and built during 1914–15 on the German side of Lake Constance. It was destroyed in a storm.
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 and 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 CL.II was a German single-engine two-seat biplane with an all metal structure, built by Zeppelin-Lindau during World War I.
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 Aviatik C.IX was a prototype German observation aircraft built by Aviatik in the final months of World War I.
The Germania C.I 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.
The Friedrichshafen FF.19 was an unarmed maritime reconnaissance floatplane built for the Imperial German Navy's Naval Air Service that was produced by Flugzeugbau Friedrichshafen. Built in small numbers, the aircraft first flew in 1914 and saw service during the early months of World War I, mostly conducting maritime patrols over the North Sea, although they did attack British ships participating in the Raid on Cuxhaven at the end of the year.
