Teledyne Marine, which is part of Teledyne Technologies Incorporated, is supporting REPMUS26, the Portuguese-led experimentation exercise that focuses on Maritime Unmanned System (MUS) experimentation, interoperability, capability, and doctrine development, where emerging technologies are evaluated in realistic naval environments to accelerate capability adoption across allied fleets. REPMUS is the largest exercise in robotics and experimentation.

The event reinforces a principle consistently demonstrated through REPMUS and similar NATO initiatives: customers acquire emerging capabilities when they are proven in relevant operational settings.

This year’s experimentation brings together NATO navies, industry, and academia to evaluate autonomous systems supporting anti-submarine warfare, undersea surveillance, rapid environmental assessment, critical undersea infrastructure protection, and maritime domain awareness.

Teledyne Marine is supporting the exercise through coordinated participation across its unmanned undersea vehicle (UUV) portfolio, including large-scale multi-glider operations utilizing 19 Slocum gliders and two Slocum Sentinel gliders, one with a towed-array system. In addition, Teledyne is supporting advanced underwater navigation demonstrations featuring Gavia Autonomous Underwater Vehicle operations supported by Benthos autonomous vehicle deployed deep ocean transponder navigation aiding technology and deployment from the ZeroUSV OCEANUS17 unmanned surface vessel.

Teledyne Marine activity at REPMUS26 is expected to include deployment and operational support for Slocum and Sentinel glider missions, coordination with allied naval operators, and technical support for Gavia UUV operations. These activities are designed to demonstrate how persistent autonomous sensing, acoustic payload integration, and navigation-aiding technologies can support distributed maritime operations across multiple mission areas.

“REPMUS provides an operationally relevant environment where emerging autonomous capabilities can be evaluated by the operators who will ultimately deploy them. Teledyne Marine brings deep expertise in unmanned undersea vehicles, persistent glider operations, acoustic sensing, navigation aiding, and at-sea technical support to help allied navies assess performance, interoperability, and mission value in realistic conditions. Through this type of multinational experimentation, we can help accelerate the transition from capability development to operational use,” said Tom Altshuler, Senior Vice President of Business Development, Marine Defense, Teledyne Marine.
