Maritime Airfield De Kooy
Maritime Airfield De Kooy is home to Royal Netherlands Air Force 7 and 860 squadrons. Both squadrons transferred from Royal Netherlands Navy (RNLN) command to the RNLAF on July 10, 2008. At De Kooy 7 squadron is responsible for training on the NH90 and its operations onboard RNLN vessels. 860 squadron has all 19 helicopters assigned after one was lost while operating in the Caribbean on July 19, 2020 resulting in the loss of two of its four crewmembers. Most of their missions are conducted in the maritime domain while occasionally land missions are flown.
423 Maritime Helicopter Squadron deployment onboard HMCS Halifax.
On New Year’s Day Her Majesty’s Canadian Ship (HMCS) Halifax left its home port of Halifax to join Standing NATO Maritime Group One (SNMG1) as part of a six-month deployment to Operation REASSURANCE. 423 Maritime Helicopter Squadron deployed on of its CH-148 Cyclone helicopters on the vessel. The Halifax operates in the Western and Northern European waters and conducts operational patrols and training with allies. During its deployment, the Halifax will serve as the flagship for SNMG1.

On April 12, 2021 HMCS Halifax arrived in RNLN harbor Den Helder for a scheduled two-week visit. The Cyclone was flown from the ship to nearby De Kooy. From the airfield the helicopter and its crew flew several missions in The Netherlands. On April 21 during a visit to De Kooy we witnessed two flights made by the crew of 23 Maritime Helicopter Squadron. The first flight departed during afternoon and saw the Cyclone fly towards Deelen Air Base to conducts its training. After arriving back at De Kooy the CH-148 was refueled and then took off early in the evening, again heading to Deelen. When it arrived back it requested time to use the slopes for some further training.
