The Fokker C.X was originally designed for the Royal Dutch East Indies Army, in order to replace the Fokker C.V, Like all Fokker aircraft of that time, it was of mixed construction, with wooden wing structures and a welded steel tube frame covered with aluminium plates at the front of the aircraft and with fabric at the rear.
The prototype was built in 1934 with a Rolls-Royce Kestrel V engine.
The East Indies Army ordered 13 C.Xs, but they were soon replaced in the scout/light bomber role by the American Martin B-10s.
Until the Japanese attack on the Dutch East Indies in 1941, the C.X remained in use as a trainer and target tug.
The Dutch Air Force ordered 16 C.Xs, and later four more with Kestrel IIS engines.
These four were later re-equipped with Kestrel V engines, the Kestrel IIS proved not very reliable.
Two C.Xs were delivered to the Spanish Republic, and four more to Finland.
The Finnish also license produced 35 C.Xs until 1942.
These C.Xs were equipped with Bristol Pegasus XII engines.
