Fokker D.I

The Fokker D.I (company designation M.18) was a development of the D.II fighter.

The D.I was also flown in Austro-Hungarian service as a fighter trainer aircraft under the designation B.III.

Confusing the matter further, both the D.II and D.I arrived at the Front in German service at similar times, in July–August 1916.

144 aircraft were built.
