Kraken Robotics successfully performed a demonstration of the Katfish sonar system in combination with its Lars autonomous launch and recovery system from Sefines RD-22 (also a USV).

What you see here is the successful combination of the Lars UPS system from Kraken Robotics and the RD-22 from Sefine. Added to this is the Katfish towed sonar system from Kraken. All in all, this robotic mix is intended to strengthen mine defence.

The demonstration of the above system combination recently took place off the coast of Istanbul, according to Kraken Robotics. Why all this? Well, recent global developments underline the importance of protecting critical maritime transportation routes and underwater infrastructure, it continues. In the future, autonomous mine countermeasure systems such as the Katfish could help naval forces to detect and classify mine-like objects more safely and quickly. By combining the two USV (Unmanned Surface Vehicle) Lars and RD-22 with Kraken Robotics Katfish, naval units could thus deploy advanced capabilities faster and more efficiently to strengthen defence and maritime security in increasingly complex environments.

The Royal Navy has already tried something similar

The demonstration therefore focused on the rapid detection and classification of suspicious objects and critical underwater infrastructure. Several naval forces and government organisations also took part in the event. Katfish provided data with a resolution of three × three centimetres, with a range of 200 meters per side, as emphasised. The data was sent live to a command center on land, enabling real-time classification of contacts by the operator using Sefine Sisam (Strategic Unmanned Systems Research Center) mission planning software. The same catfish and USV-Lars system was demonstrated by an eleven-meter Arcims USV (Atlas Remote Combined Influence Minesweeping System USV) of the British Royal Navy in November 2025.
