No coffee mugs rattling in the galley. Just a silent, autonomous machine prowling the depths. In this video, I break down what the LUUV is, what it can do, and why it matters for Europe’s security.

With undersea infrastructure like pipelines and data cables now high-value targets, autonomous sentinels like the LUUV could
