Threat Outlook
Region | Threat Level | Assessment |
Americas | Low | Threat level increased from Very Low to Low, as PLA militants demonstrate UAV capabilities to hit maritime assets. |
Europe | Very High | The Black Sea remains highly dangerous for commercial shipping as a target for subsea, surface and aerial drones, including in coastal areas. Vessels traversing the Baltic sea route to Russia, also seem to have elevated risk. |
Gulf of Aden | High | Consistent threat from Somali PAGs and Houthi's. Suspicious approaches are regularly reported in the area. |
Gulf of Guinea | Low | Anchorages remain high risk of petty theft and robbery. |
Northwest Indian Ocean | Very High | The Hormuz conflict remains severe, with both U.S. and Iranian military strikes involving commercial shipping. |
Southeast Asia | Low | Petty theft and robberies are a consistent theme in the Singapore Strait and surrounding waters. |
Operational Guidance
Operators should:
Watch for Drones & Explosives: Maintain sharp lookouts for UAVs, waterborne drone boats (USVs), and floating naval mines in the Black Sea and the Strait of Hormuz.
Anti-Piracy Watches: Enhance deck security and water-spray readiness against armed boarding and knife attacks in the Singapore Strait.
Obey Chokepoint Blockades: Avoid the Strait of Hormuz TSS due to military strikes, routing instead through Omani waters under strict U.S. Navy (NCAGS) coordination.
Deploy Active Deterrence: Ensure experienced Armed Security Teams (ASTs) are active and ready to use lethal force to repel small-craft attacks in the Gulf of Aden.
Monitor Security Broadcasts: Maintain a continuous watch on VHF Channel 16 and closely track critical UKMTO, MSCIO, and JMIC regional updates.
Stopping Boardings Before They Start
Most maritime attacks succeed once criminals reach the main deck.
That’s why leading operators rent physical anti-boarding barriers:
No upfront CAPEX
Global deployment
Short or long-term rental
No vessel modification
Zero successful boardings. Ever.
