Fokker D.XVII

Problems with severe vibration in the Armstrong Siddeley Jaguar radial engine on the Fokker D.XVI resulted in one being converted to use a normally aspirated 500 hp (370 kW) Curtiss Conqueror V-1570 V-twelve, becoming the prototype for the D.XVII.

[4] On 18 January 1935, Lieutenant René Wittert van Hoogland set a Dutch high-altitude record in a Fokker D.XVII of 10,180 m (33,400 ft) while using oxygen and high octane fuel.

By May 1939, the aircraft was obsolete and remaining examples were transferred to the LVA Flying School for fighter pilot training however they saw some action during the Battle of the Netherlands, escorting Fokker C.Vs and C.Xs on bombing missions.

Nevil Shute and a Fokker representative "who was well accustomed to methods of business in the Balkans" spent three weeks in Athens but they did not close the deal.
