Koolhoven F.K.58 Fighter (1940)

Authored By Staff Writer | Last Updated: 5/8/2012

Only twelve complete examples of the Dutch Koolhoven FK-58 fighter were ever completed, some seeing combat in the fateful Battle for France of June 1940.

There are currently no production history notes available for the Koolhoven F.K.58 Fighter. Rest assured that we are hard at work on adding more information to the Military Factory so please check back at another time down the road.

Each entry goes through a lengthy research process that produces the final write up. The write up is then complemented by appropriate imagery for the associated text through a lengthy picture hunting process. Statistics are then verified before the entry is completed in our database and posted for review.

For the interim, please consider busying yourself with another section on MilitaryFactory.com.
