New anti-submarine warfare tech comes in a 20-foot container

Ultra Maritime, a US-based defense manufacturer, has developed Sea Tracker, a modular anti-submarine warfare (ASW) system housed in a standardized 20-foot ISO container. Designed for uncrewed and non-traditionally crewed platforms, Sea Tracker delivers frigate-grade submarine detection capabilities, enhancing situational awareness and preparedness in complex maritime environments. This innovation aims to help the US Navy and its allies effectively track and counter increasingly stealthy and long-range submarines deployed by rivals such as China and Russia. The need for advanced submarine detection is critical due to the evolving underwater threats posed by nuclear submarines, which provide strategic advantages in surprise and intelligence gathering. China and Russia have recently made significant advancements in submarine detection and undersea surveillance technologies, challenging Western naval dominance. Sea Tracker’s modular architecture integrates Ultra Maritime’s suite of towed technologies, including torpedo defense systems and strategic surveillance arrays, enabling rapid deployment and comprehensive tracking and classification of stealthy submarines. Ultra Maritime is collaborating with Canadian defense
