Deeply Innovative: Drivers in Subsea Defense

seabed surveillance.A New Era of Maritime DefenseFrom ruggedized cables to long-endurance autonomous platforms, the companies in this year’s MTR100 represent far more than engineering excellence; they are shaping the future of maritime defense. Advances in power systems, navigation technology, sonar imaging, and unmanned vehicles are converging to create an undersea domain that is more connected, persistent, and resilient than ever before. As subsea threats evolve, these innovators are delivering the situational awareness and operational superiority essential to securing the ocean depths

interaction and allows for control of multiple Tritech products from within one software package. Software development kits (SDKs) are also available for Windows and Linux operating systems“With its ultra-low-noise differential analogue front-end supporting a wide dynamic range optimised for sonar imaging applications, and with its ability to actively attenuate waterborne electrical noise from other subsea equipment, the Gemini 1200id provides work class ROV operators the clarity and confidence necessary for mission critical operations,” added Asim Azad, Hardware Engineering Manager

EdgeTech High-Res Sonar Facilitates Missing Aircraft Discovery

A side scan sonar technology from EdgeTech, a developer high resolution sonar imaging systems and underwater technology, has proved instrumental in helping to locate an aircraft that has been missing for over fifty years.  In 1971 a plane departed from Burlington International Airport bound for Providence RI but crashed enroute, presumably in Lake Champlain.Searches were carried out at the time of the crash, but weather made the operations difficult.  In subsequent years many other searches were completed to no avail. In May 2024, utilizing pieces of information from prior surveys
