Headquartered in the United Kingdom, this firm delivers cutting-edge sensors and countermeasures that help naval forces detect the quietest submarines and defend against stealthy torpedoes.

From providing the Royal Navy with state-of-the-art sonar for new frigates to equipping NATO partners with world-leading ASW suites, the company stands out as a key asset in strengthening collective deterrence.
