Germany's answer to the Sopwith Triplane: the Fokker Dr1 was described by German Ace Baron Manfred Von Richthofen as being able to "Climb like monkeys and manoeuvre like devils", and proved to be an excellent weapon, if only for a short period of time.
It was relatively slow compared to other fighters coming into service at the time and there was a tendency for the top wing to fail accounting for the small number of only 320 ever being built. The first batch was delivered to front line units in mid October 1917 and production continued until May 1918.
The aircraft was of mixed wood and metal construction with no bracing wires except for on the central inverted v tubular steel struts and on the undercarriage assembly.
The normal engine was a 110hp Oberursel rotary but were often retro-fitted with captured French 110hp Le Rhone engines, which gave better performance.
