The Gotha G.I was a bomber aircraft used by the Luftstreitkräfte during the First World War.
The AEG C.II was a German two-seat biplane reconnaissance aircraft produced in small numbers from October 1915. It was a slightly smaller version of the C.I with better performance, redesigned cockpit for both pilot and observer/bombardier, new rear mounting for a 7.92 mm (.312 in) Parabellum MG14 machine gun, and the ability to carry four 10 kg (22 lb) bombs for light attack duties.
The Albatros C.III was a German two-seat general-purpose biplane of World War I, built by Albatros Flugzeugwerke. The C.III was a refined version of the successful Albatros C.I and was eventually produced in greater numbers than any other C-type Albatros.
The Albatros C.I,, was the first of the successful C-series of two-seat general-purpose biplanes built by Albatros Flugzeugwerke during World War I. Based on the unarmed Albatros B.II, the C.I reversed the pilot and observer seating so that the observer occupied the rear cockpit which was fitted with a ring-mounted 7.92 mm (0.312 in) Parabellum MG14 machine gun.
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.
Friedrichshafen FF.33 was a German single-engined reconnaissance three-bay wing structure biplane, using twin floats, designed by Flugzeugbau Friedrichshafen in 1914 for the Marine-Fliegerabteilung aviation forces of the Kaiserliche Marine.
The Hansa-Brandenburg W.29 was a German two-seat fighter floatplane which served in the closing months of World War I with the Imperial German Navy's Naval Air Service from bases on the North Sea coast. In concept the aircraft was a monoplane version of the biplane Hansa-Brandenburg W.12, although there were many structural differences between the two.
The LFG Roland C.II, usually known as the Walfisch (Whale), was an advanced German reconnaissance aircraft of World War I. It was manufactured by Luft-Fahrzeug-Gesellschaft G.m.b.H.
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.
Entering service in 1915, the Rumpler C.I,, two-seater single-engine reconnaissance biplane, was one of the first German C-type aircraft, and also one of the longest serving in its class during World War I, being retired from the last front line units only in early 1918.
The DFW C.IV, DFW C.V, DFW C.VI, and DFW F37 were a family of German reconnaissance aircraft first used in 1916 in World War I. They were conventionally configured biplanes with unequal-span unstaggered wings and seating for the pilot and observer in tandem, open cockpits. Like the DFW C.II before them, these aircraft seated the gunner to the rear and armed him with a machine gun on a ring mount. Compared to preceding B- and C-class designs by DFW, however, the aerodynamics of the fuselage were more refined, and when coupled with more powerful engines, resulted in a machine with excellent performance.
The Roland D.VI was a German fighter aircraft built at the end of World War I. It lost a fly-off to the Fokker D.VII, but production went ahead anyway as insurance against problems with the Fokker.
The Gotha WD.2 and its derivatives were a family of military reconnaissance aircraft produced in Germany just before and during the early part of World War I.
The Rumpler B.I was a military reconnaissance aircraft produced in Germany during World War I.
The Rumpler C.III was a biplane military reconnaissance aircraft built in Germany during World War I.
The Rumpler G.I was a bomber aircraft produced in Germany during World War I, together with refined versions known as the G.II and G.III.
The Siemens-Schuckert R.I was a bomber aircraft built in Germany during World War I. It was originally ordered as the Siemens-Schuckert G.I prior to the German Inspectorate of Flying Troops adopting the "R" classification for multi-engine aircraft in late 1915. Some sources refer to the aircraft as the Siemens-Schuckert Steffen R.I, including the name of the brothers that designed it.
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 Phönix C.I, given serial numbers in the Phönix 121 range, was an Austro-Hungarian First World War reconnaissance and general-purpose Biplane built by Phönix and Lloyd.
