UK MoD invests £90 million in AI underwater surveillance equipment

On November 10, 2026, the UK Ministry of Defence announced a £90 million investment to procure a new batch of unmanned underwater vehicles, detection sensors and a supporting AI monitoring system for the Royal Navy. The equipment will be used to protect subsea telecommunications cables and energy pipelines across the North Atlantic, as well as to conduct underwater target search operations.

The project, codenamed Atlantic Network, forms the first phase of the UK military's broader Atlantic Bastion programme. The autonomous system network is designed to deploy alongside manned naval vessels, using AI to integrate data collected underwater, automatically generate maritime domain awareness picture, and push early warning signals to anti-submarine warfare vessels and nuclear submarines in advance, addressing surveillance gaps left by traditional maritime patrols.

The relevant procurement framework agreement has already been signed with UK-based companies. At this stage, the programme remains at the framework agreement phase, with no public timeline yet for final delivery or operational deployment.
