Key Incidents by Region
Northwest Indian Ocean
6 June 2026Â
Iranian forces conducted a ballistic missile attack targeting the United States Naval Support Activities in Bahrain. CENTCOM confirmed that six of the missiles were successfully intercepted by air defense systems. The seventh missile suffered an in-flight failure and crashed before reaching its target. No injuries were reported.
5 June 2026
U.S. forces boarded a sanctioned stateless tanker approximately 20NM southwest of Sri Lanka. The tanker claimed false registry and had previously sailed under a false flag. Reports indicate the tanker was carrying around 1.9 million barrels of Iranian crude oil and had been in the area for 6 weeks.
2 June 2026Â
U.S. Forces disabled an Botswana-flagged oil tanker that was approaching towards Kharg Island, Iran. CENTCOM enforced blockade measures against the unladen tanker after the crew ignored repeated warnings and refused to comply with U.S. forces over a 24 hour period. A U.S. aircraft ultimately disabled the vessel by firing a hellfire missile into the engine room. The tanker was successfully prevented from reaching Iran.
1 June 2026Â
A cargo ship was attacked 40NM Southeast of Umn Qasr, Iraq. The vessel reported a large explosion following a hit from an unknown projectile on the starboard side. The UKMTO reported that a second impact occurred, resulting in a fire which has since been extinguished. No injuries to crew has been reported.
Gulf of Aden
6 June 2026Â
A merchant vessel reported being suspiciously approached on two separate occasions by suspicious boats. The first incident occurred near 12°58.73’N 048°11.76’E, and featured a small craft carrying 7 people. The second incident occurred 12°53.10’N 048°20.50’E,15 minutes after the first one, and involved a white dhow carrying eight to ten people. In both incidents, the approaching craft disengaged after defensive measures were taken including the deployment of armed security personnel. No injuries or damage were reported.
Europe
6 June 2026Â
Russia conducted UAV strikes targeting two Ukrainian Search and Rescue Service (SAR) vessels whilst they were actively performing a humanitarian mission inside Ukraine’s TTW. The vessels, with clear identification as nonmilitary rescue crafts, suffered physical damage to both hulls and superstructures. Several injuries were sustained amongst crew members. The Ukrainian Navy deployed rapid-response vessels to evacuate the wounded personnel whilst under fire.
5 June 2026Â
Open sources reported that a naval drone exploded in the civilian section of the Port of Constanța, Romania. The drone, which was clearly linked to the war in Ukraine, was discovered earlier in the port area and had been isolated by security forces before it self-detonated. The explosion caused material damage to port infrastructure, but no casualties were reported.
5 June 2026Â
Open sources show that two cargo vessels have been struck near the port of Taganrog, Russia. The vessels were in transit from Türkiye to Rostov-on-Don to load grain when the incident occured. Both vessels were struck multiple times. One, sailing under the flag of Belize, experienced a fire and loss of propulsion. The second vessel, registered under the flag of Palau, suffered a fire which killed three crew members. The remaining crew abandoned ship and was evacuated.

Southeast Asia
5 June 2026Â
A Marshall Islands-flagged bulk carrier reported an attempted robbery whilst transiting the Phillip Channel. The crew sighted three perpetrators on the upper deck. The vessel’s master stated that all crew is safe and is unable to determine if items were stolen. The vessel will continue her voyage to NPOC, Singapore.
5 June 2026Â
A Marshall Islands-flagged bulk carrier reported an attempted robbery whilst underway in the Philip Channel. The crew sighted six perpetrators armed with knives and a gun-like object in the engine room. The vessel’s master reported that everyone is safe and was unable to determine if items were stolen. The vessel was able to continue her voyage to NPOC, Singapore.
3 June 2026Â
An armed robbery occurred onboard the Maltese-flagged containership, CMA CGM Valparaiso, whilst at anchor in Manila Anchorage, Philippines. Four robbers, armed with three guns and a knife, held the duty watchman at gunpoint and forced him to open the bosun’s store. The perpetrators tied the watchman’s hands with rope before escaping with stolen ship's stores. The watchman freed himself and alerted the Officer of the Watch who raised the general alarm.
Americas
6 June 2026
A large fire erupted in the artisanal fishing sector of the Port of Manta, Ecuador. The fire began on one boat and spread with extreme speed as many small-to-medium artisanal vessels are constructed of highly flammable materials. Authorities confirmed that 35 vessels were completely destroyed (14 artisanal fishing boats, and 21 motorized skiffs). As the fire reached onboard fuel tanks, a chain of loud explosions echoed across the harbor, injuring four workers. Investigations concluded the disaster was caused by a welding accident rather than organized crime related sabotage.
Threat Outlook
Region | Threat Level | Assessment |
Americas | Very Low | Sporadic petty thefts and maritime accidents. |
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 form 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 Houthi 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 & Mines: Maintain sharp lookouts for UAVs, waterborne drone boats, and floating naval mines in the Black Sea, Sea of Azov, and Strait of Hormuz.
Anti-Piracy Watches: Enhance security against armed boardings in the Singapore Strait and Manila Anchorage.
Obey Chokepoint Restrictions: Avoid the Strait of Hormuz Traffic Separation Scheme and coordinate all transits directly with U.S. naval forces (NCAGS).
Deploy Active Deterrence: Use armed guards, fire hoses, and evasive maneuvers to repel small-craft and pirate approaches in the Gulf of Aden.
Monitor Security Broadcasts: Maintain a continuous watch on VHF Channel 16 and closely track UKMTO, JMIC, and local NAVWARN alerts.
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.
