1. Teledyne Marine & Rutgers Deploy Long-Endurance Glider for Global Research Voyage
Teledyne Marine and Rutgers University-New Brunswick launched a mission to circumnavigate the globe with an autonomous underwater glider. The near five-year Sentinel Mission departed on 10 October 2025, following a ceremony at the Woods Hole Oceanographic Institution (WHOI). The mission will use Teledyne’s ‘Redwing’, a next-generation Slocum Sentinel Glider, launched from the edge of the continental shelf south of Martha’s Vineyard, Massachusetts.
2. Kraken SAS Demonstrates Interoperability at REPMUS 2025
A record number of participants used Kraken Robotics Synthetic Aperture Sonar (SAS) technology during the annual Robotic Experimentation and Prototyping with Maritime Unmanned Systems (REPMUS) exercise in Portugal. 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.
3. Robosys Secures Contract to Integrate VOYAGER AI into AMC Search USV
Robosys Automation is set to supply its advanced VOYAGER AI software as a retrofit for the AMC Search OPT WAMV-16 Unmanned Surface Vessel (USV). Robosys’ VOYAGER AI remote operations and maritime autonomy software will be integrated with the WAM-V 16 USV to provide enhanced autonomous navigation, real-time decision-making, and adaptive mission planning capabilities.
4. NORBIT Subsea Delivers Multibeam Sonar for Autonomous Subsea Mapping
NORBIT Subsea has delivered its multibeam sonar to the Exail DriX USV platform for ORLEN Petrobaltic S.A., part of ORLEN S.A. The NORBIT multibeam sonar system is engineered using advanced analog and digital signal processing technologies, ensuring high sensitivity and accuracy. This system is optimized for demanding offshore environments, delivering high-quality data and long-range performance.
5. D-2 Unveils Hybrid AUV-CTD Sensor for Underwater Vehicle Navigation & Data
D-2 Inc. has introduced the AUV-CTD sensor, designed to deliver real-time conductivity, temperature, and depth measurements, along with calculated salinity and sound velocity data, for use on UUVs, gliders, floats, and profilers. The AUV-CTD is built around the hybrid conductivity sensor, which combines elements of electrode and inductive conductivity measurement.
