HII and Thales have successfully integrated the SAMDIS 600 synthetic aperture sonar with HII’s REMUS 620 medium-class unmanned underwater vehicle (UUV), completing a joint field exercise in Pocasset, Massachusetts, at the end of August.
The milestone marks a significant advance in autonomous mine countermeasure (MCM) and subsea security capabilities for allied navies. The exercise demonstrated how the multi-aspect SAMDIS 600 sonar seamlessly combines with the long-endurance, modular REMUS 620 platform to deliver autonomous mine detection, classification, and high-resolution imaging.
According to the companies, the integration offers a leap forward in undersea operations by providing forces with improved efficiency, accuracy, and interoperability in complex environments.
“Teaming the Thales’ advanced SAMDIS 600 sensor in the REMUS 620 underscores the power of collaboration in driving innovation for our customers,” said Duane Fotheringham, president of Mission Technologies’ Unmanned Systems business group at HII. “This milestone demonstrates not only the adaptability of the REMUS 620 but also the strength of industry partnerships in delivering next-generation solutions that enhance undersea dominance for NATO and allied forces.”
Thales UK Underwater Systems managing director Paul Armstrong added: “SAMDIS empowers missions with enhanced efficiency and effectiveness, serving as a crucial enabler for precise acoustic identification through its high-resolution SAS capabilities. This achievement reflects the strong collaboration with HII, delivering advanced solutions for the benefit of our users’ missions.”
The SAMDIS 600 sonar provides multi-aspect synthetic aperture sonar (SAS) imaging, enabling operators to detect and classify mines with high precision, even in challenging seabed conditions. Combined with the REMUS 620’s modular design, extended endurance, and multi-payload capability, the pairing is designed to strengthen NATO and allied navies’ ability to conduct mine countermeasures, protect subsea infrastructure, and enhance wider undersea security operations.
