The D VII was a biplane fighter conceived by Reinhold Platz, the gifted designer of the Dr I triplane fighter. The D VII had a fuselage of welded steel tube covered with aluminum and fabric, and thick-section wooden wings covered with plywood and fabric. The VII prototype revealed the need for a longer fuselage and fixed fin in addition to the comma-shaped moving rudder. So revised, the VII was entered in the January 1918 fighter competition held at Johannisthal airfield, and proved the unanimous choice of the fighter pilots. Large production contracts were placed with Fokker and, somewhat ironically, with Fokker’s great rival Albatross.
The D VII entered combat in April 1918 with a 160-hp (119 kW) Mercedes D III inline with an auto-type radiator (the first German plane to feature one) and proved an immediate winner against the best British and French fighters. Late in the year a more powerful BMW engine replaced the Mercedes unit, much improving the fighter’s rate of climb.
The D VII possessed good performance, and was easy to fly yet responsive to the controls right up to it’s ceiling, where the type could hang on its propeller without loss of control. Some 700 D VII’s were in service at the time of the Armistice, and the type was the only aeroplane specifically mentioned in the Treaty of Versailles for surrender to the Allies. After the First World War, Anthony Fokker returned to the Netherlands and resumed limited production of the D VII.
