But in the near future we also see our drones operating in different European countries in the northern part of Europe.”Due to Denmark’s location between the Baltic Sea and the North Sea, the Royal Danish Navy plays a strategic role in monitoring and safeguarding maritime traffic through the Danish Straits, a gateway between the two seas.The 33-foot Voyager is designed for coastal surveillance and nearshore mapping missions, performing continuous maritime intelligence, surveillance, and reconnaissance (ISR), seafloor characterization, as well as real-time domain awareness, according to data from Saildrone. Powered by an electric motor and enabled with a mapping speed of 5 knots, the USV can operate for 100 days between service stops.Voyager USVs can perform “maritime domain awareness and the ISR for a long period of time. More than three months out in station and being out there without doing anything, just being a forwarding sensor providing the data,” Sørensen said.In addition to the Voyager, Explorer and Surveyor platforms, Saildrone is also developing a new product, Spectre, a 170-foot USV that will join the portfolio as its largest and fastest platform that will carry weapons.“With our Spectre platform, there will be kinetic effectors,” Sørensen said. “It’s a container-based solution. You could either have two 40-foot containers or five 20-foot containers of various payloads, including kinetics on that platform. That will be built in 2027.”Jaroslaw Adamowski is the Poland correspondent for Defense News.
