Autonomous maritime vehicles become key players in port security and defence against underwater threats

By: Noah News

Autonomous maritime technologies are rapidly evolving from experimental platforms into essential tools for port and offshore security, as operators respond to increasing threats both above and below the waterline. Driven by advances in AI, sensor integration, and real-time data processing - as well as rising geopolitical and commercial risks - ports are adopting uncrewed surface and underwater systems to enhance persistent surveillance, detection, and response capabilities. At the same time, this technological shift is reshaping the threat landscape, with autonomous vehicles themselves emerging as potential weapons.

Amid this transformation, companies across the maritime security ecosystem are building integrated solutions that combine detection, classification, and rapid response. ThayerMahan is highlighted as a key player on the defensive side of this evolution, with its SeaGuard system representing a move toward non-kinetic countermeasures against hostile underwater drones and diver threats. Positioned within a broader “detect-to-defeat” framework, ThayerMahan's approach reflects a growing industry imperative: not only to monitor increasingly complex underwater environments, but to actively protect critical port infrastructure from autonomous, fast-deploying threats.
