Metron, a leader in autonomous software innovations for defense and commercial applications, and Cellula Robotics, a leading provider of robotic undersea platforms, announced the successful completion of a multi-mission open-water demonstration off the coast of Vancouver, Canada. The sea trial showcased the integration of Metron's Autonomous Navigation Command and Control (ANCC) software with Cellula's Guardian UUV—an autonomous, long-duration, multi-payload platform designed to increase mission success in contested and complex environments. When equipped with Cellula's advanced hydrogen fuel cell technology, the Guardian is capable of operational ranges up to 5,000 km and endurance of 45–60 days—significantly surpassing the performance of similarly sized battery-powered systems. The demonstration marked the culmination of a yearlong series of UUV operations featuring Cellula platforms integrated with Metron's ANCC.
