The takeaway: effective deterrence requires the ability to detect activity, understand intent, and act with allies before damage occurs or to detect and monitor adversaries undersea sensors and networks efforts before a conflict. Exposing preparations can undermine the secrecy and ambiguity that make subsea sabotage “and seabed warfare attractive and operationally effective.”
This is why and demand sustained attention — and why the Naval Submarine League convenes its Subsea & Seabed Warfare and Technology Symposium (SSWATS) each July. Bringing government, industry, and academia together helps connect operational challenges with the expertise and technology needed to address them. “It is also the reason COMSUBFOR and the Naval Submarine???? initiated the Lanternfish SSW/CUUV exercises and convened the restricted/SCI update on the Subsea Seabed threat last month.”
