The Coastguard in the Netherlands is a service that is made possible through the collaboration of various ministries, but operates under the direct responsibility of the Ministry of Defence. The Coast Guard has, among other things, a police task in the field of environmental checks at sea. Two Dornier 228-212 aircraft are used for this. These aircraft will be replaced by PAL Aerospace Dash 6 aircraft. The first will probably be delivered in spring 2022
Agusta Westland 189
The Coast Guard will receive 2 helicopters of the type Agusta Westland 189 (AW189). Bristow flies and maintains the aircraft for a period of 10 years. The aircraft can accommodate 19 people excluding crew. The crew on board consists of 2 pilots, a winch operator, a rescue swimmer and an ambulance nurse as standard.

The aircraft will remain in England until November to train personnel. After that, the device comes to the Netherlands.
