Tekever and General Dynamics Mission Systems–Canada have detected and tracked underwater contacts using sonobuoys deployed from an AR5 uncrewed aircraft during REPMUS 2026. The demonstration off Portugal linked the aircraft, acoustic sensors and mission-management systems, sharing detections with the wider operational picture in real time.

The work demonstrated a distributed anti-submarine warfare capability, from deploying sonobuoys at sea to processing their acoustic data and presenting underwater detections to operators. It combined Tekever’s AR5 and ATLAS mission-management platform with General Dynamics’ acoustic technology and Distributed Acoustic Processing System.

“The maritime mission does not stop at the waterline,” said Pedro Petiz, Tekever’s director for Portugal. “Our customers need to understand what is happening above and below the sea and use that understanding as part of the same mission.”

The companies’ approach brings aerial surveillance and underwater sensing into a common operational picture. They said connecting those sources would help operators make faster, better-informed decisions rather than assess activity above and below the surface separately.

“At REPMUS, our team demonstrated an important step forward in distributed Anti-Submarine Warfare, successfully deploying sonobuoys from a Tekever AR5 and processing the resulting acoustic data to detect and track underwater contacts,” said Tony Morris, vice-president of Air and Naval Systems at General Dynamics Mission Systems–Canada. “By bringing together autonomous platforms, sensors and mission systems, we are enabling a more connected approach to anti-submarine warfare that can give operators greater situational awareness across the battlespace.”

The demonstration builds on cooperation between the companies at previous REPMUS exercises. This year’s work further integrated autonomous platforms, acoustic sensing and mission management to support naval awareness above and below the surface.
