A New Arms Race Unfolds on the Ocean Floor
· World · CNBC
Governments and defense companies are increasing security measures for critical underwater infrastructure amid growing concerns over hybrid warfare and seabed vulnerabilities. Subsea connectivity cables and energy pipelines traversing the ocean floor are becoming prime targets, drawing substantial funding and new surveillance technologies.
