UK Launches £90M ‘Atlantic Net’ Project to Protect Undersea Cables and Hunt Submarines

The United Kingdom announced a proposed £90 million framework with Ocean Infinity Solutions for Atlantic Net, an autonomous maritime surveillance network serving the Royal Navy's Atlantic Bastion programme. The architecture will combine uncrewed vessels, underwater sensors, communications, remote operations and data services to detect submarines and monitor critical seabed infrastructure across the North Atlantic. Surveillance information is intended to provide earlier warning to anti-submarine warships and Astute-class attack submarines while extending observation beyond crewed patrols. The framework was announced at an international sea-power conference in Oslo on November 10, 2026, with detailed equipment quantities and delivery schedules still unspecified.
