Fokker D.III

The Fokker D.III (Fokker designation M.19) was a German single-seat fighter aircraft of World War I.

It saw limited frontline service before being withdrawn from combat in December 1916.

The M.19 began as an effort to improve the performance of the Fokker D.II (Fokker designation M.17).

The M.19 featured the Oberursel U.III 14-cylinder, two-row rotary engine, combined with the two-bay wing cellule of the Fokker D.I.

The U.III engine, first used in the Fokker E.IV, required a revised fore-and-aft mount and a strengthened fuselage.

The prototype M.19 arrived at Adlershof for testing on 20 July 1916. 

The Idflieg issued a production order for 50 aircraft at that time, followed by orders for an additional 60 aircraft in August and 100 in November.

The new aircraft was designated D.III by Idflieg.

210 were built.
