Military multi purpose aircraft, 1938

The type number F.K.59 has been used for three Koolhoven designs: a two-engined float plane, an open two-seat sports plane and a single engined military biplane developed from the F.K.52. Of these three aircraft it was the single engined biplane that made it to production as Koolhoven F.K.59. It was the last Koolhoven design in production.

Other sources mostly show a photo of the two-engined float plane as F.K.59, but this was just a mock-up, not an actual aircraft, neither a prototype.
