The Fokker C.XI was developed by Fokker based upon specifications of the Dutch navy for Sea Scouts in 1935.
The aircraft was built in traditional Fokker-way, with a linen-covered, welded steel tube fuselage and wooden wings. The wings of unequal span were positioned diagonally above the other.
The aircraft was suited to be launched from cruisers with a (steam) catapult [Hr MS De Ruijter was fitted with a Heinkel steam catapult]. Before that time had to be put aboard aircraft on board with a crane, a time-consuming process.
The prototype made on July 20, 1935 the first flight was followed by extensive tests with the slingshot. These were successfully completed, followed by an order for thirteen production aircraft.
