The Royal Netherlands Navy has officially received its latest asset, the HNLMS Den Helder, a combat support ship designed to enhance weapon systems integration. This delivery, which took place in North Holland, marks the completion of the remaining tasks associated with the replenishment vessel’s five-year construction project.
Once deployed, the HNLMS Den Helder will play a crucial role in transporting and supplying essential resources such as fuel, ammunition, water, food, and other goods between shore facilities and Dutch assets, as well as to various NATO partners in the region. This strategic support capability reflects the Netherlands’ commitment to bolstering operational readiness within the alliance.
The assembly of the Den Helder was conducted in Galați, Romania, where the construction was finalized. The vessel embarked on its journey back to the Netherlands in November 2024, undergoing simultaneous sea trials en route. After a month-long voyage, it arrived in Vlissingen, Zeeland, where it underwent final adjustments and extensive testing before commissioning.
The support ship was officially christened in February 2025 by Dutch Crown Princess Catharina-Amalia, marking a key milestone in its readiness to replace the aging 60s-era oiler platform that had been sold to Peru after its retirement in 2014.
Later this year, the Den Helder will be commissioned into the Royal Netherlands Navy and operate from its home port in North Holland. Measuring 180 meters (590 feet) in length, the ship has accommodations for approximately 150 personnel and the capacity to carry up to 20 ISO-standard metal cargo containers. Depending on its operational requirements, the Den Helder can also transport landing craft vehicles or two helicopters, comparable to the NH90 medium-sized aircraft.
In addition to its support capabilities, the Royal Netherlands Navy plans to equip the Den Helder with weaponry suitable for its operational environment. This includes a 76-millimeter naval gun capable of firing piercing ammunition, 12.7-millimeter machine guns, and surface-to-air missiles, providing it with both defensive and offensive capabilities.
Powered by four Wärtsila 31 engines and twin GE electric motors, the Den Helder can reach speeds of up to 20 knots (37 kilometers/hour or 23 miles/hour), ensuring that it can rapidly respond to various mission needs in dynamic maritime environments.
