REPMUS (Robotic Experimentation and Prototyping using Maritime Uncrewed Systems) is one of the world’s largest and most advanced exercises for autonomous and unmanned maritime systems, bringing together NATO, industry, academia, and research organizations to evaluate emerging technologies in realistic operational environments. For Evolo, REPMUS provides a unique large-scale testing ground where advanced hydrofoiling platforms can be evaluated in demanding real-world conditions alongside international autonomous systems and command-and-control infrastructures. The exercise enables rapid experimentation of sensors, control systems, communications, autonomy, and operational concepts that would be difficult to replicate in traditional laboratory settings. Participation in REPMUS as the Ghostfoiler has played an important role in validating Evolo technology for future civilian, research, and defense maritime applications.
