HII and Thales have successfully integrated the SAMDIS 600 sonar with the REMUS 620 medium-class unmanned underwater vehicle (UUV), completing trials at HII’s Pocasset facility in Massachusetts.
The project merges high-resolution synthetic aperture sonar with a long-endurance, modular undersea platform, creating a capability for autonomous detection, classification, and mapping of subsea objects with potential military applications.
The SAMDIS 600 is tailored for mine detection, underwater surveillance, and infrastructure protection.
The REMUS 620, measuring 7 meters (23 feet) in length, offers over 24 hours of endurance, can travel up to 80 kilometers (50 miles) at a speed of 5 knots (9 km/h, 6 mph), and dive to 1,000 meters (3,280 feet).
Together, the integration enhances mission efficiency, with both companies noting the effort as an example of how industrial collaboration can deliver advanced solutions for defense operations.
