RE:RE:HII - US Navy Sales further
The marine technology landscape is witnessing a pivotal shift with the increasing adoption of synthetic aperture sonar (SAS). Once confined to naval forces for mine countermeasure operations (MCM), SAS is now being embraced by commercial and scientific sectors, marking a crossover from defense to conservation. NOAA's recent acquisition of two REMUS 620 unmanned underwater vehicles (UUVs) from HII exemplifies this trend. These medium-class UUVs, customized with a synthetic aperture sonar module, additional energy modules, and auxiliary equipment, are a testament to the growing preference for advanced SAS technology. Compared to traditional Real Aperture Side Scan Sonar systems, SAS offers higher resolution, improved imaging, and better area coverage rates. This enables more detailed imaging of underwater terrain, continuous pulses for better visualization, and enhanced efficiency in mapping and exploration.NOAA plans to deploy the REMUS 620 UUVs for higher-resolution mapping of the Gulf of Mexico and restoration efforts to repair seafloor habitats damaged by the 2010 Deepwater Horizon oil spill. These UUVs will also support various ocean mapping activities, including marine archeology and habitat characterization. The integration of SAS technology in UUVs like the REMUS 620 demonstrates its versatility and potential for broader use beyond mine countermeasure operations. As the marine industry continues to innovate, the adoption of advanced technologies like SAS opens up new possibilities for marine restoration and conservation, contributing to the preservation of our oceans and marine ecosystems.
