Royal Navy Partners with Ocean Infinity for Undersea Surveillance

The UK Ministry of Defence has announced a £90 million investment in Atlantic Net, a network of drones, seabed sensors, and artificial intelligence to detect Russian submarines and protect undersea cables in the North Atlantic. The system, built and run by Ocean Infinity Solutions, will provide the Royal Navy with earlier warning of threats and a clearer picture of activity beneath the surface.
