07/31/2019. Remarks by Johan Visschedijk: "Essentially a progressive development of the D.XVI with a Curtiss V-1570 Conqueror engine, the D.XVII embodied a number of aerodynamic refinements white retaining the basic structure of the earlier fighter and its armament of two 0.312 in (7.92 mm) M.36 machine guns. Ten production examples were ordered by the NethAAS, the 590 hp Rolls-Royce Kestrel IIS twelve-cylinder liquid-cooled engine being selected as the standard power plant and deliveries commencing in October 1932.
The ninth and tenth aircraft were respectively and temporarily powered by the 800 hp Lorraine-Dietrich Petrel 12Hfrs and the 760 hp Hispano-Suiza 12Xbrs, both eventually reverting to standard Kestrel-engined configuration. The Conqueror-engined prototype was shipped to the Netherlands East Indies for KNIL evaluation, being shipped back to Holland in 1936 after a crash, and then being rebuilt and delivered to the NethAAS. Relegated to the fighter training role prior to WW II, the seven surviving D.XVII fighters saw some limited operational use during the German invasion of the Netherlands in May 1940."
