Fokker C.IV / CO-4
First flown in 1922, this two-seat biplane was one of the first completely new products of the Fokker company after its post-war move from Germany to Holland.
Stemming from the C.1 prototype, it was built with two sizes of wing, which could be exchanged in about an hour. The small wings were used on the C.IV-A and DC.1 fighters and the large on the more numerous C.IV-B, C and seaplane W. Some dozens were used by the Dutch and other air forces.
The prototype C.IV had a 400 hp Liberty engine. The C.IV was built as a successor to the C.I, being more spacious and able to transport more equipment. The C.IVA fighter-scout had less wing span, whilst the C.IVB and the C. IVC scouts had a greater span. Fokker manufactured 139 C.IVs and a number were also built in Spain.
The C.IV was a float-plane. The C.IV was a great success, and was used in America (where it was known as the CO-4), Argentine, Italy, Holland and the Dutch East Indies, Russia and Spain.
The C.IV was built in Madrid by Jorge Loring, under license from Fokker.
