Underwater vessels are essential for defence, research, offshore energy, and environmental monitoring—operating in some of the most extreme and unpredictable conditions on Earth.
By integrating Marine AI’s GuardianAI™ Software Suite, autonomous and remotely operated underwater vessels (AUVs and ROVs) gain advanced situational awareness, intelligent decision-making, and mission adaptability.

Autonomous Navigation & Obstacle Avoidance
Underwater vessels map, navigate, and adapt in complex subsea environments by leveraging advanced sonar, inertial navigation systems (INS), and AI-driven pathfinding.
Real-Time Data Collection & Analysis
Equipped with multi-sensor fusion, underwater vessels can autonomously gather high-resolution data for seabed mapping, pipeline inspection, and environmental monitoring, relaying insights via secure communications.
Long-Endurance Missions
With the reduced need for human intervention, AUVs can conduct deep-sea surveys, defence operations, and offshore inspections with extended mission duration.
Cooperative Autonomy & Multi-Vehicle Coordination
GuardianAI supports swarm operations, enabling multiple underwater vessels to collaborate on large-scale missions, increasing efficiency and data coverage.
Defence & Security Applications
AUVs support mine countermeasures, anti-submarine warfare, and subsea reconnaissance, enhancing situational awareness in high-threat environments.
Whether for scientific research, security, or commercial operations, GuardianAI™ enables the next generation of underwater autonomy.
The Royal Navy submarine Excalibur (a 12-metre long, 2.2-metre diameter XLUUV) is designed to monitor underwater hostile activity and shape the future of anti-submarine warfare. It is capable of payload deployment and recovery on the seabed, and has a range of over 1,000 miles.
MarineAI is working with MSubs, integrating the full executive autonomy software stack with low-level control of the submarine’s electrical systems. Excalibur is capable of three-dimensional obstacle avoidance, and continuous communication with support vessels during a mission enables fully informed autonomous decision making.
