De Kooy Airfield (EHKD/DHR) is a military-civilian airfield located adjacent to the Royal Netherlands Navy's main base in Den Helder, on the northern tip of the North Holland peninsula. Originally established in the early 20th century for naval aviation operations, it continues to serve Defense Helicopter Command flights alongside limited general aviation traffic. The airfield's coastal location near the Marsdiep tidal channel gives it a strategic role in North Sea patrol and Search and Rescue (SAR) operations.
💡 Local Tip
If you're flying in, check the winds carefully — the airfield sits right next to the Marsdiep strait, and crosswinds from the North Sea can shift abruptly, especially during afternoon sea breezes in spring and summer.
🚖 Getting There
Den Helder is best reached by car via the N9 motorway from Alkmaar, which connects to the A9 toward Amsterdam. The nearest railway station is Den Helder, about 6 km from the airfield, with a taxi or local bus completing the journey. Parking is available directly on-site for general aviation visitors.
