The crew has been confirmed safe and the environmental impact remains unknown while authorities investigate.

UKMTO issued Warning 166-26 classifying the event as an attack. The warning advised vessels to transit with caution and report any suspicious activity.

Why Two Separate October 11 Warnings Regarding A Tanker Being Hit With A Projectile Within The Strait

United Kingdom Maritime Trade Operations issued two distinct attack warnings for outbound tankers struck by projectiles in the Strait of Hormuz on 11 October.

  • Warning 164-26, released on 11 October, reports an incident at 12:00 UTC. A company security officer stated that an outbound tanker was struck on the port side by an unidentified projectile. The vessel sustained damage. All crew were reported safe and no environmental impact was reported at the time of the attack.

  • Warning 166-26, released the following day as a time-late report, covers an outbound tanker struck by an unknown projectile on 11 October. Incident time remains TBC. The crew has been confirmed safe and the environmental impact is unknown. Authorities are investigating.

UKMTO has not linked the two warnings or issued an update treating them as the same event. The products carry sequential numbers, different sources of information, and different levels of detail.

Warning 164-26 supplies a specific time, the reporting party, the side of the vessel hit, and a damage assessment. Warning 166-26 is more general and still lists environmental impact as unknown.

A third October 11 event remains separate. Warning 165-26, later updated, concerns a tanker near Sohar anchorage, Oman, reclassified as a UAV strike with local authorities assisting in crew evacuation.

The pattern of multiple verified reports of projectile strikes on outbound tankers on the same day is consistent with UKMTO’s recent sequence of numbered warnings in the Strait of Hormuz.

No official body has confirmed that Warning 164-26 and Warning 166-26 describe the same vessel.
