Helicopter Exercise "Centaur Hammer"
From Monday, August 17, through Thursday, August 20, and on Monday, August 24, and Tuesday, August 25 (weeks 34 and 35), helicopter crews from the Defense Helicopter Command will be training in a temporary low-altitude flight zone in the northeastern Netherlands.
During the “Centaur Hammer” exercise, Apache crews train in a scenario in which they must fly toward and neutralize (ground) targets.
During the exercise, four Apache attack helicopters may be visible and audible in the areas surrounding the municipalities of Westerveld, Assen, Het Hogeland, and neighboring municipalities.

Flight Times and Surrounding Area
The exercise on the dates listed above will take place during the following times:
- 9:00 a.m. to 4:30 p.m.
During the exercise, densely built-up areas, industrial and port areas, and large gatherings of people will be avoided as much as possible. Flight paths and altitudes, as well as exercise locations, will be selected in such a way as to minimize noise pollution as much as possible.
Advice for Farmers
Experience from previous exercises shows that (young) livestock can be startled by sudden low-altitude flights.
Recommendation from the Department of Defense:
- Keep animals indoors whenever possible, or in a spacious, sheltered pasture.
- Turn on a radio in the barn to mask sudden noises.
- Health Young livestock are not kept alone but in a group, which reduces stress.
- Discuss precautionary measures with neighbors or fellow livestock farmers.
- If desired, consult your veterinarian about additional measures.
Information and Notifications Regarding Flight Movements
The Ministry of Defense takes great care in preparing military exercises, including military flights. This is essential not only for all flying units of the Royal Netherlands Air Force, but also for the areas where the Ministry of Defense conducts its exercises. We spread flight operations as much as possible across the various training areas in the Netherlands. All of the Ministry of Defense’s low-altitude flight routes and areas can be found onthis page:.
Operational and weather conditions may cause exercises to proceed differently than previously announced.
More Information and Complaints
The Ministry of Defense recognizes that flight operations can cause a nuisance. You can report this on the Ministry of Defense website using theonline complaint form at. Visitluchtmacht.nl/vliegbewegingen for more information about flight operations and exercises.
