Fokker D.VII
![]() To compete in Germany’s first single-seat fighter competition during January 1918, Fokker produced its V 11 prototype (with 30 other aircraft including six Fokker types), which used many Dr I structural and design features in a biplane layout with a 119-kW (160-hp) Mercedes DIII inline engine. The V.11 prototype revealed the need for a longer fuselage and fixed fin in addition to the coma shaped rudder before entering. The type displayed sparkling performance and agility, and the D VII production model began to enter service in April, initially with the DIII engine but later with the BMW III for improved performance at altitude.
The D.VII is a single-bay biplane, without bracing wires, two-spar wooden wings, with plywood leading-edges and wire trailing edges. Ailerons were on the top wing only. The welded steel-tube fuselage and tail unit, and wings were all fabric covered. An aerofoil lifting surface was between the wheels.
The D.VII was the most successful fighter of World War One. Fokker won an order for 400 machines during the fighter competition of January 1918. The V.11, prototype of the D.VII only just met the deadline, and Fokker had had no opportunity to test it, so he was obliged to do this whilst demonstrating it during the meeting.

One D VII was used by the newly established Czechoslovak Air Forces at the Cheb Training School from 1918.

By the end of World War I more than 700 D VIIs had been delivered, and the type won enormous approval and respect from German and Allied pilots for its agility as well as its good performance and handling even at high altitude. Another important feature was its capacity to hang on its propeller, allowing pilots to fire upward when other fighters would have stalled and entered a spin. There were many variants, none produced in quantity.
