An unknown projectile disabled an outbound tanker in the strait on 23 October. UKMTO's warning to masters came three days later.
A tanker was disabled in Hormuz three days before masters were told.
UKMTO, the British naval office that takes security reports from merchant ships in the region, issued a "verified, time-late report" on 26 October1. An unknown projectile had disabled a tanker outbound through the Strait of Hormuz at 08:39 UTC on Friday 23 October; the crew were safe.
The alert reached masters three days after the hit, so ships that crossed the strait in that window had no UKMTO notice of it. Two days before the strike, UKMTO had reported a tanker hit off Bukha in Oman.
UKMTO is a small Royal Navy office that sends warnings to merchant ships about dangers at sea, much like a traffic alert for sailors. On 26 October it warned that a tanker had been knocked out by an unknown object three days earlier as it left the strait of Hormuz. The crew were not hurt. The warning was marked "time-late", meaning it was checked before being sent. That checking took three days, during which other ships had no official word of the attack.
Ships under attack often report first to their owners, their flag state or their insurers, not to UKMTO. The desk depends on that chain passing the report on, and a reluctant owner can sit on it.
Many ships in the strait now sail with tracking transmitters off, which makes it harder for any outside body to confirm a hit independently. Verification then rests on the crew's own account, which takes time.
Masters weighing a Hormuz crossing may rely more on IRGC statements and private security firms when official alerts arrive days late.
The 23 October hit adds a verified incident to a week when most strike claims came only from the Guards.
