Fokker DR-1


SN - 528189

FAA Reg - N6404Q


The Fokker Dr.I (Dreidecker, "triplane" in German), often known simply as the Fokker Triplane, was a World War I fighter aircraft built by Fokker-Flugzeugwerke. The Dr.I saw widespread service in the spring of 1918. It became famous as the aircraft in which Manfred von Richthofen gained his last 19 victories, and in which he was killed on 21 April 1918.

In February 1917, the Sopwith Biplane began to appear over the Western Front. Despite its single Vickers machine gun armament, the Sopwith swiftly proved itself superior to the more heavily armed Albatros fighters then in use by the Luftstreitkräfte. In April 1917, Anthony Fokker viewed a captured Sopwith Biplane while visiting Jasta 11. Upon his return to the Schwerin factory, Fokker instructed Reinhold Platz to build a triplane, but gave him no further information about the Sopwith design. Platz responded with the V.4, a small, rotary-powered triplane with a steel tube fuselage and thick cantilever wings, first developed during Fokker's government-mandated collaboration with Hugo Junkers.


Initial tests revealed that the V.4 had unacceptably high control forces resulting from the use of unbalanced ailerons and elevators. Instead of submitting the V.4 for a type test, Fokker produced a revised prototype designated V.5. The most notable changes were the introduction of horn-balanced ailerons and elevators, as well as longer-span wings. The V.5 also featured interplane struts, which were not necessary from a structural standpoint, but which minimized wing flexing. On 14 July 1917, Idflieg issued an order for 20 pre-production aircraft. The V.5 prototype, serial 101/17, was tested to destruction at Adlershof on 11 August 1917.
