US Borrows Iran's Own Trick to Skirt the Hormuz Checkpoint

Since early May, the U.S. military has been covertly overseeing ship-to-ship oil transfers in the Gulf of Oman, deploying a logistical technique previously associated almost exclusively with Iranian sanctions evasion to keep regional energy exports moving.

The operation, reported by Reuters, targeted two locations: waters off Fujairah in the United Arab Emirates and off Sohar in Oman, both outside the zone Iran has designated under the oversight of its Persian Gulf Strait Authority (PGSA).

The PGSA-designated supervision area sits within and adjacent to the Strait of Hormuz, through which roughly 20 percent of the world's traded oil passes.

Iran's Technique, America's Operation

The method of transferring oil cargo between tankers at sea rather than in port has, for years, been a primary tool Iran has used to obscure the origin and destination of its own sanctioned crude exports.

Washington has resorted to the method in an attempt to sustain energy flows in a corridor where Iranian leverage is at its peak.

Iran has defined a specific area within and around the Strait of Hormuz as subject to its armed forces' oversight, a designation that has periodically been used to justify vessel inspections, detentions, and interdictions.

The U.S. operation beginning in early May appears calibrated to work around that perimeter without direct confrontation inside it.

The transfers allow cargo to be shifted from vessels that may face restrictions or exposure within the strait onto others that can proceed without the same risk profile, effectively disaggregating the logistical chain to reduce single points of vulnerability.

Downed Apache and Retaliation

Sources familiar with the mission told Reuters that a U.S. military Apache helicopter, shot down by Iran on June 9, was part of the extensive, clandestine effort to smuggle oil out of the Gulf.

The downing of the Apache by Iran sparked retaliatory bombings by the U.S. military.

Both crew members of the downed helicopter were subsequently rescued by a drone boat. The use of military helicopters to guide these convoys highlights the operational scope of the U.S. mission.

A Quietly Strategic Precedent

The operation's secrecy underscores the sensitivity of the arrangement.

Publicly acknowledging that the U.S. military is running offshore transfer operations modeled on Iranian sanctions-evasion practices carries diplomatic and legal implications that neither Washington nor its Gulf partners have addressed on the record.

The two host locations, UAE and Oman, both maintain working relationships with Iran alongside their security partnerships with the United States, adding a further layer of geopolitical delicacy to an already complex logistical arrangement.
