The system demonstrated its ability to integrate data from different sensors at the REPMUS 2026 maritime uncrewed systems exercise, Saab said. It also autonomously handed off tracked objects to the exercise’s central command system using a NATO-standard protocol.
“The free flow of goods is the fundamental engine of the modern global economy,” said Åsa Schöllin, head of Underwater Systems within Saab’s Naval business area. “In a grey zone scenario or conflict an aggressor may try to disrupt vital sea lines of communication thereby damaging both economic activity and military logistics.”
Ocean Barrier has three defensive perimeters, called Detect, Prevent and Protect, which can operate independently or as part of a wider system. The configuration can be tailored to a single harbour, naval base or offshore installation, or extended to coastlines and national waters.
“With Ocean Barrier we provide customers with a scalable and future-ready solution that delivers continuous awareness, enabling faster decisions and more effective protection of critical assets and maritime areas,” Schöllin said. Its sensor-agnostic design allows integration with existing surveillance systems.
Saab said the modular, cyber-secure architecture would allow operators to add sensors, technologies and analytical capabilities over time. That flexibility is intended to accommodate changing threats and operational requirements.
