The Siemens-Schuckert D.IV was a late-World War I fighter aircraft from Siemens-Schuckert (SSW). It reached service too late and was produced in too few numbers to have any effect on the war effort.
The Albatros D.XI was a German single-seat fighter biplane first flown in February 1918. It was the first Albatros fighter to use a rotary engine, in the form of the 120 kW (160 hp) Siemens-Halske Sh.III, and also featured a new wing construction with diagonal struts from the fuselage replacing traditional wire bracing.
The Albatros L 59 was a single-seat German utility aircraft of the 1920s. It was a single-engine low-wing cantilever monoplane with large, spatted wide track undercarriage attached, unusually for the time not to the fuselage but to the wing roots. The whole aircraft was covered in 3-ply.
The Albatros L 69 was a two-seat German parasol monoplane racing and training aircraft of 1925. It was a single-engine parasol-wing monoplane of conventional configuration that seated the pilot and passenger in tandem, open cockpits. It was advertised as a trainer, however contemporary reports dismissed this due to the difficulty in accessing the front cockpit, and the designers' focus on performance.
The Albatros L 82 was a 1920s German trainer biplane. Of conventional configuration, it seated the pilot and instructor in separate, open cockpits. The wings were single-bay, equal-span, and unstaggered.
The Dornier Libelle, also designated Do A, was a German open-cockpit, all-metal, parasol wing, monoplane flying boat aircraft, with partly fabric-covered wings. A landplane version, built without sponsons and fitted with a fixed tailwheel undercarriage was produced as the Dornier Spatz.
The Focke-Wulf A.16 was a German three/four passenger light transport monoplane designed by Heinrich Focke and Georg Wulf and was the first design built by the newly formed Focke-Wulf company.
The Focke-Wulf A 17 Möwe was an airliner built in Germany in the late 1920s. It was a conventional high-wing cantilever monoplane with fixed tailwheel undercarriage. The aircraft provided fully enclosed seating for up to eight passengers and had a separate, fully enclosed flight deck for the two pilots. Most examples flew with Deutsche Luft Hansa, serving until around 1936. In the early 1930s, two A 17s were used for testing the Junkers Jumo 5 diesel engine.
The Henschel Hs 122 was a German army cooperation/reconnaissance aircraft of the mid-1930s, radial-engined and with a parasol wing. Though only pre-production variants entered service, the Hs 122 led on to the Hs 126 which was produced in large numbers.
The Junkers T 19, originally known as the J 19, was a single-engined parasol winged all-metal 2/3-seat aircraft built in Germany in the early 1920s for training and touring. Its construction was too expensive for commercial success and only three were built, one later finding use as an engine test-bed.
The Focke-Wulf GL 18 was a 1920s German light transport monoplane, designed and built by Focke-Wulf.
The Siemens-Schuckert D.VI was a single engine, single seat, parasol wing German fighter aircraft flown in 1919.
The Siemens-Schuckert DDr.I was a World War I German twin engine, push-pull configuration triplane fighter aircraft. Only one was built, crashing on its first flight.
The LFG Roland D.IX was a World War I German single seat fighter aircraft, a biplane powered by one of a new generation of powerful rotary engines. Three slightly different prototypes were built but there was no series production.
The LFG V 40 and V 44 were one-off, single-engine, two-seat sports monoplanes, identical apart from their engines, built in Germany in 1925.
The Udet U 1 was the first of a line of small, low-powered, low wing, cantilever monoplanes built in Germany in the early 1920s.
The Dietrich-Gobiet DP.VII was a simple, low power, German sports aircraft flown in early 1924.
The parasol wing, single engine Udet U 8, sometimes referred to as the Limousine, was a three-seat commercial passenger transport designed and built in Germany in 1924. Five were produced and were used by German airlines until about 1928.
The Raab-Katzenstein KL.1 Schwalbe (Swallow) was a German two-seat biplane produced in the 1920s. About fifty were built and the type became well known as an aerobatic aircraft, performing at many displays in the hands of pilots like Gerhard Fieseler.
The Działowski D.K.D.4 was a Polish, parasol-wing, sports two-seater built in 1928. One won the Second National Lightplane Contest, with another coming fifth.
