UKMTO

Royal Navy centre coordinating merchant-shipping security across the Indian Ocean and Persian Gulf.

Background

United Kingdom Maritime Trade Operations is a Royal Navy coordination centre headquartered at the Maritime Trade Information Centre on Portsdown Hill, Portsmouth, with a liaison office in Dubai. Founded in 2001 as a post-9/11 confidence-building measure, it serves as the primary point of contact between merchant shipping and naval forces across the Indian Ocean, Persian Gulf, Arabian Sea and Red Sea, receiving distress reports, issuing navigational warnings and coordinating military responses. It works alongside the US-led Combined Maritime Forces but operates independently under British command.

The centre has become the de facto early-warning system for maritime conflict in the Gulf during the 2026 war: its incident reports are cited by insurers, governments and media as the authoritative record of attacks, and its warnings directly trigger war-risk insurance surcharges and rerouting decisions affecting billions of dollars in freight. The event record includes and .

Key Issues
Gulf shipping advisories

It became the record everyone checks

UKMTO raised its Hormuz advisory to critical on 4 May, and had already logged Warning 041-26 on 22 April after an IRGC Navy gunboat struck a merchant vessel just seven hours into a Trump-announced Ceasefire extension, the third attack on commercial shipping in four days . Its bulletins give the initial position and description of an incident; flag states and owners typically issue the confirming follow-up once verified.

By 5 August, when Houthi forces claimed strikes on two tankers, UKMTO had logged only one confirmed explosion and had not said which vessel was hit, a gap its own reporting model is built to surface rather than resolve .

Maritime incident tracking

UKMTO confirms the war's tanker strikes

UKMTO confirmed the first maritime strike of the Iran conflict when an Israeli-owned vessel was hit off the Fujairah coast, and by 18 April 2026 had confirmed IRGC gunboats firing directly on an Indian-flagged super tanker in the strait, a new category of incident with a state naval force attacking a third-country vessel.

On 7 July 2026, UKMTO reported a second, unnamed tanker struck in the same overnight window as an IRGC missile strike on the Qatari LNG carrier Al Rekayyat near Limah, Oman, extending its record as the first body to confirm multi-vessel attacks within hours of occurrence. Its incident reports remain the closest thing to a real-time maritime battlefield log, cited by insurers, governments and media as the authoritative record of attacks in the strait.
