Fokker D.VII
WW I fighter aircraft
The Fokker D.VII was a German World War I fighter aircraft designed by Reinhold Platz of the Fokker-Flugzeugwerke. Germany produced around 3,300 D.VII aircraft in the second half of 1918. In service with the Luftstreitkräfte, the D.VII quickly proved itself to be a formidable aircraft. The Armistice ending the war specifically required, as the fourth clause of the "Clauses Relating to the Western Front", that Germany was required to surrender all D.VIIs to the Allies. Surviving aircraft saw much service with many countries in the years after World War I.

Development and production
Fokker's chief designer, Reinhold Platz, had been working on a series of experimental V-series aircraft, starting in 1916. The aircraft were notable for the use of cantilever wings. Hugo Junkers and his aviation firm had originated the idea in 1915 with the first practical all-metal aircraft, the Junkers J 1 monoplane, nicknamed Blechesel (Sheet Metal Donkey or Tin Donkey). The wings were thick, with a rounded leading edge. The shape of the wings' airfoil gave greater lift, with its relatively "blunt" leading edge (as seen in cross-section) giving it more docile stalling behavior than the thin wings commonly in use.
Operational history
When the Fokker D.VII entered squadron service with Jasta 10 in early May 1918, Allied pilots at first underestimated the new fighter because of its squarish, ungainly appearance. However, their experiences in combat quickly forced them to revise their view. The type quickly proved to have many important advantages over the Albatros and Pfalz scouts. Unlike the Albatros scouts, the D.VII could dive without any fear of structural failure. The D.VII was also noted for its high manoeuvrability and ability to climb, its remarkably docile stall and reluctance to spin. It could "hang on its prop" without stalling for brief periods of time, spraying enemy aircraft from below with machine gun fire. These handling characteristics contrasted with contemporary scouts such as the Camel and SPAD, which stalled sharply and spun vigorously.

The earliest production D.VIIs were equipped with 170–180 hp Mercedes D.IIIa. Production quickly switched to the intended standard engine, the higher-compression 134 kW (180–200 hp) Mercedes D.IIIaü. Some early production D.VIIs delivered with the Mercedes D.IIIa were later re-engined with the D.IIIaü.
