History
This type was released to succeed the Fokker C.III, which was built in a small series for Spain.
In fact it was a development from the Fokker C.I. The aircraft, in fact a long range scout, had a rather broad fuselage, with much room for the crew, who appreciated this very much.
A disadvantage was the decrease of the maximum speed
Three variants were developed:
- Fokker C.IVA:
- with a smaller wing span of 12,07 m;
- Fokker C.IVB:
- with a larger wing span of 12,91 m
- Fokker C.IVC:
- with a wing span of 14.28 m.
According to Fokker, the wings could be exchanged by four men within 45 minutes.
Three aircraft were sold to the USA, after a demonstration for General Mitchell. These aircraft were tested under the designation CO-4 #1 till CO-4 #3 (CO-4 = Corps Observation model 4).
One of these aircraft was completely restored to flying condition at the Owl Head Museum. (check website: Fokker C.IV flies again.)
A smaller version was the Fokker D.C.I. only used by the NEIAF.
Spain intended to built the D.C.I under license, but choose to built and use the Fokker C.IV, of which twenty were built at Madrid.
In 1924 200 aircraft were exported to Russia and in 1923 the Argentine navy ordered three aircraft equipped with floats.
