Kraken displays trailer-mounted Sentinel sonar

Kraken Robotics displayed a trailer-mounted Sentinel intruder-detection sonar at Apex Europe 2026 in London, offering a deployable system for detecting divers and underwater vehicles. Sentinel combines simultaneous active and passive sonar with 360-degree coverage, with stated detection ranges of up to 1,000 metres for divers and unmanned underwater vehicles and 1,500 metres for crewed underwater vehicles. The trailer carries the sonar and tripod, cables, a diesel generator, monitoring equipment and a retractable ten-metre communications mast. It provides up to 80 hours of autonomous power and can operate independently or within a wireless network of ten trailers.
