At the annual Robotic Experimentation and Prototyping with Maritime Unmanned Systems (REPMUS) exercise in Portugal, a record number of participants used Kraken Robotics’ Synthetic Aperture Sonar (SAS) technology.
Seven international naval teams and three Uncrewed Underwater Vehicle (UUV) manufacturers employed Kraken’s SAS technology for a range of maritime security applications, including mine countermeasure operations and critical underwater infrastructure inspections. Their participation demonstrated effective interoperability across platforms, nations, and mission objectives in the underwater domain.
Greg Reid, President and CEO of Kraken Robotics, commented, “This year we saw Kraken SAS usage at REPMUS double compared to last year, with ten teams leveraging Kraken systems. Hands-on operational trials like REPMUS are invaluable—they let us collaborate with operators under real conditions so we can refine product roadmaps and continue to deliver the best solutions for tomorrow’s missions.”
This marks Kraken’s fourth consecutive year supporting REPMUS, with an increasing number of participants using Kraken SAS each year, from one in 2022 to 10 in 2025. This year, Kraken SAS was integrated across four different types of UUVs, from small-class to large-class.
Kraken personnel provided shore-side integration and data support, collaborating with users on best practices for efficient and accurate operations. Systems captured data at a constant 3 cm x 3 cm resolution, revealing mine-like objects and subsea cables as small as 5 cm diameter.
The 2025 REPMUS exercise brought together more than 30 nations, 2000 participants, and 250 autonomous assets to test naval interoperability in realistic operational environments.
