Twenty six compliant industry proposals have been assessed during the first formal tendering phase of the Atlantic NET programme, the Ministry of Defence has confirmed, following parliamentary questions about the status of emerging undersea surveillance systems. Responding on behalf of the department, Minister of State Luke Pollard said that no procurement decisions have yet been taken. “The first formal element of the tendering process for Atlantic NET commenced in September 2025 and was completed in January 2026,” he said. The modular platform has been promoted for long endurance missions including intelligence, surveillance and seabed monitoring. Seabed Sentry, developed by Anduril, is a seabed based sensing concept intended to provide persistent underwater surveillance through distributed autonomous nodes, rather than through a single vehicle platform.
