About

About Oceanus12

Oceanus12 is a 12-metre autonomous uncrewed surface vessel built for persistent blue-water missions. Its hybrid diesel-electric powertrain supports 20–36 days of endurance, while a 4.0 by 2.2 metre aft deck accepts mission payloads up to 1,000 kg and supplies up to 30 kW. The hull is designed for transport within a 40-foot ISO footprint and mobilisation in less than half a day.

The modular platform can carry survey, acoustic, sensing and deployable payloads for defence, maritime security, hydrographic, scientific and logistics work. In Plymouth trials it autonomously launched two Oshen C-Star surface drones under MarineAI’s GuardianAI autonomy layer, demonstrating a carrier role inside a coordinated multi-platform mission.

Timeline

Oceanus12 autonomously deploys two C-Star surface drones
2026-08-25 - Demonstration - The UK Defence Innovation-backed programme is led by ZeroUSV with Oshen and MarineAI. MarineAI’s GuardianAI autonomy suite coordinated Oceanus12 and the C-Star vehicles with minimal operator input. The two C-Stars were configured for acoustic-data collection; the next planned phase would deploy four vehicles simultaneously.
