The Fokker D.IV was a German fighter biplane of World War I, a development of the D.I.^[2]^[3]

Development[edit]

The Fokker D.IV had a more powerful Mercedes D.III engine, and was the first Fokker front-line design to use ailerons in place of wing warping from the start for roll control.^[4]

Operational history[edit]

The aircraft was purchased in small numbers (40) by the German Army but it is thought that only 1 aircraft flown by Hans von Keudell of Jasta 1 saw any service on the Western Front all others being relegated to a training role or home defense duties. This was because of a general ban placed on the front-line use of Fokker aircraft on 6 December 1916 due to poor workmanship and a lack of quality control at the factory.

The Swedish Air Force also bought four examples of the type powered by 150 h.p. Benz Bz.III engines.,^[1]^[5] but only 1 was assembled and armed, the remaining 3 being stored in a dismantled state.
