Damen Naval selects VHT for ASWF RAS and helicopter transfer systems

Dutch shipyard Damen Naval has awarded Van Halteren Technologies (VHT) two contracts for the Dutch-Belgian Anti-Submarine Warfare Frigate (ASWF) programme covering the delivery of replenishment-at-sea (RAS) systems and helicopter transfer systems (HTS), Damen announced on 15 April 2025.

VHT was selected for its expertise and proven track record demonstrated in previous collaborations, according to Damen. The Dutch company is focused on the design and manufacturing of specialised systems, technical solutions and services for defence and industrial applications.

Recently, VHT completed successful RAS testing for the Combat Support Ship (CSS) Den Helder. For the ASWF, the integration of RAS receivers into the ships’ superstructures marks a significant engineering innovation.

VHT’s RAS systems, designed for the safe transfer of liquids and solids at sea, are fully customisable and designed for safe, reliable operations under demanding naval conditions. Additionally, VHT’s helicopter transfer systems are designed for both manned and unmanned helicopters.

“These contracts mark another important step in delivering a future-proof platform that will strengthen European security and co-operation,” Fer Tummers, ASWF project director at Damen Naval, was quoted as saying in a company press release. “We value working with trusted partners like Van Halteren Technologies who share our commitment to innovation.”

“The ‘proven in practice’ RAS and HTS systems will be fully integrated into the ASWF platform as a project,” added Charles Simons, sales manager for naval systems at VHT. “The contribution to the ASWF programme is an excellent example to demonstrate the knowledge and expertise for drive-and-control technology in co-operation with Damen Naval.”

The ASWF programme, under which two frigates each will be received by the Royal Netherlands Navy and the Belgian Naval Component, sets “a new European standard for advanced anti-submarine warfare vessels”, according to Damen.

The ASWFs are set to replace the Karel Doorman class and are designed for anti-submarine warfare while also being able to counter surface and air threats. They feature a low acoustic signature, advanced sensors, high survivability and integrated automation. The multi-role frigates are also capable of handling lower-intensity operations, including counter-piracy, anti-terrorism and maritime security operations.

The first ASWF is scheduled to be delivered by Damen Naval in 2028.
