About

Online Oceans is a UK-based maritime defense startup developing autonomous surface vessels and a cloud-based command-and-control platform for persistent maritime coverage. Their offering combines the Scout, a compact solar-powered autonomous surface vessel, with Tether, a platform for mission management, asset monitoring, and real-time data access. They target use cases such as anti-submarine warfare, subsea infrastructure protection, border security, and counter-drug smuggling, providing a cost-effective alternative to traditional crewed vessels.
