DUBM 44

The DUBM 44 is a high-resolution, side-scan synthetic aperture sonar ( SAS ) designed to replace DUBM 41 sonars in service with France's ANTARES -class sonar vessels and for a new unmanned surface vessel (USV) for power projection and fleet support operations. Thales designates the system as the T-SAS (Towed Synthetic Aperture Sonar). In French service, the sonar is known as the DUBM 44.

The sonar is designed to detect very small targets across the full swath of 656 ft (200 m)...
