Fokker D.IV

The Fokker D.IV was a German fighter biplane of World War I, a development of the D.I.

Development
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.

Operational history
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., but only 1 was assembled and armed, the remaining 3 being stored in a dismantled state.
