Valkenburg Naval Air Base

Though officially closed as an airport, it still sees limited use for special events and by gliders and occasionally small piston aircraft, most from the local flying club Aeroclub Valkenburg.

Current plans are to use the area for housing development, but part of the former air base may remain in use for glider flying.

After Germany occupied the Netherlands, the German military completed construction of the air base for their own use, naming it Fliegerhorst Katwijk.

The military stationed Eurocopter Cougar, AH-64 Apache and CH-47 Chinook helicopters at the former Naval Air Base for this purpose.
