The UK and France have locked in operational plans for a multinational mine-clearing mission in the Strait of Hormuz, the narrow waterway where roughly 120 vessels pass through daily carrying a significant chunk of the world’s oil supply. The operation, finalized on June 4, 2026, follows a potential agreement between the US and Iran and aims to restore commercial shipping through waters allegedly seeded with mines by Iran’s Islamic Revolutionary Guard Corps.
The logistics of sweeping a war zone
Preparations for this mission have been anything but last-minute. The UK’s RFA Lyme Bay, already stationed off Gibraltar, was loaded with autonomous mine-hunting drones and ammunition in late May 2026. The coalition itself is substantial. Up to 40 partner nations have been coordinated under a UK-France-led framework, a level of multinational cooperation that intensified after a multi-nation summit held in April 2026.
UK Armed Forces Minister Al Carns has been careful about timelines, stating that deployment would only begin when conditions were right for restoring safe shipping routes. The mission is contingent on a ceasefire or peace accord between the US and Iran, which could materialize in the days following any formal agreement.
