Ukraine has developed a new unmanned surface vessel, the “Harpun,” designed for maritime operations. The drone boat weighs 100 kilograms and possesses the ability to remain in a waiting state for up to two days before executing a strike on command. A key feature of the Harpun is its water-jet engine, enabling swift movement and maneuverability. To counter electronic warfare tactics, the drone rapidly switches between three control channels, effectively evading jamming attempts. This technology aims to enhance the drone’s reliability and operational effectiveness in contested maritime environments. The Harpun represents Ukraine’s continued innovation in unmanned systems as part of its defense strategy. Further details regarding its payload and deployment specifics have not been disclosed.
