airport
De Kooy Airfield (Dutch: Vliegveld De Kooy) (IATA: DHR, ICAO: EHKD) is an airfield 2.9 NM (5.4 km; 3.3 mi) south of Den Helder, Netherlands, named after the nearby hamlet De Kooy. It serves as both a civilian airport under the name Den Helder Airport and a naval airport under the name Naval Air Station De Kooy (Dutch: Maritiem Vliegkamp De Kooy).
Most movements on the De Kooy are made by helicopters, bringing workers to and from offshore oilrigs and naval helicopters such as the NH90 of the Naval Aviation Service of the Royal Netherlands Navy. Fixed-wing aircraft visit and operate from the airport alongside. Skyline Aviation operates from De Kooy, mainly operating business aircraft and also do airwork such as aerial photography for civilian and military contractors. Amongst its fleet of aircraft most noticeable are several Aero L-39 Albatros jets.
History
The airport was constructed in 1918 for the Royal Netherlands Navy, whose primary base was and still is located in Den Helder. A seaplane base already existed nearby on the south side of Texel however the navy required an airport for conventional aircraft as well. The base came under German control during the Second World War and was renamed Fliegerhorst De Kooy. It suffered heavy damage during the war, this despite the construction of heavy anti-aircraft defences in the area.

Why this record matters
“De Kooy Airfield” is worth following because a concise public description often conceals a longer documentary argument. Here, Kooy, Airfield and airport provides the most credible route into that argument.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Aug 27, 2026. The linked authority identifier is Q1431193. Authority coordinates are 52.922, 4.783. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1918.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
