Teledyne Marine Puts Cutting-Edge Sonar To The Test At SeaSEC Harbour Challenge Ahead Of Navy Tech 2026
Teledyne Marine has successfully demonstrated its advanced sonar technology during the SeaSEC Harbour Protection Challenge Day on 2nd February in Gothenburg, Sweden – just ahead of its participation at Navy Tech & Seabed Defence 2026, when the company was also exhibiting and delivered two expert speaker sessions.
The live harbour protection exercise which focused on detecting and tracking underwater threats in port environments, served as a real world prelude to Teledyne Marine’s presence at the Navy Tech event (3–5 February 2026).
Teledyne Marine has successfully demonstrated its advanced sonar technology during the SeaSEC Harbour Protection Challenge Day on 2nd February in Gothenburg, Sweden – just ahead of its participation at Navy Tech & Seabed Defence 2026, when the company was also exhibiting and delivered two expert speaker sessions.
The live harbour protection exercise which focused on detecting and tracking underwater threats in port environments, served as a real world prelude to Teledyne Marine’s presence at the Navy Tech event (3–5 February 2026).
During the one-day harbour protection exercise, Teledyne Marine deployed its SeaBat F50 forward-looking sonar, mounted on a seabed frame to monitor vessels and underwater vehicle activity entering and exiting the harbour. The scenario focused on the detection, tracking and visualisation of unmanned underwater vehicles (UUVs), including autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs).
Designed for situational awareness underwater, the SeaBat F50 delivers a wide swath covering up to 140 degrees horizontally. The wide swath and high ping rate mean the SeaBat F50 delivers high-resolution, real-time imagery for effective harbour and critical underwater infrastructure protection.
Morten Bernsdorf, Senior Project Manager at Teledyne Marine, said: “During the SeaSEC Harbour Challenge, the SeaBat F50 delivered a clear, real-time view of underwater activity in a busy harbour setting. Combined with a Teledyne FLIR thermal imaging camera, we were able to detect, track and follow underwater vehicles as they moved through the area. These exercises allow us
to prove our technology in realistic conditions and refine how multi-sensor approaches can strengthen harbour defence.”
Following its live demonstration, Teledyne Marine showcased the SeaBat F50 on its stand throughout Navy Tech & Seabed Defence, where delegates could visit their stand to learn more about the system and discuss insights gained from the SeaSEC mini challenge.
Teledyne Marine also presented its Compact Navigator at Navy Tech for the first time. The world’s smallest and highest performing, fully integrated autonomous navigation solution is ground-breaking, ultra-compact and advanced. It redefines performance in a small form factor, making it ideal for small vehicles and enabling inspection and survey applications not previously achievable.
Other technologies on display included a passive acoustic monitoring system (PAM), the Gavia AUV and a Gavia Module featuring an integrated SeaBat T20 sonar.
Teledyne Marine experts delivered two presentations on the event’s opening day: • Thomas W. Altshuler, Ph.D., Senior Vice President, Global Maritime Defence Strategy and Business Development Emerging UUV and Sensor Technologies for Defensive and Offensive Subsea and Seabed Warfare (SSW)
• Ed Cheesman, Business Development Director, Defence and Security Enablers (and Blockers) to Rapid Scale Up of Maritime Unmanned Systems (MAS)
