In recent months, the United States military has employed covert ship-to-ship oil transfer operations to circumvent Iran’s blockade of the Strait of Hormuz, ensuring the continued flow of Gulf energy exports. This strategy mirrors tactics previously utilized by Iran to evade international sanctions.
**Covert Oil Transfer Operations**
Since early May 2026, the U.S. military has overseen numerous clandestine ship-to-ship oil transfers near the Strait of Hormuz. These operations involve guiding convoys to awaiting tankers using aerial and water drones, as well as helicopters. The transfers occur at two specific locations: off the coast of Fujairah in the United Arab Emirates and near Oman’s port of Sohar. Satellite imagery and shipping data indicate that at least 92 vessels have participated in these operations since early May.
**Operational Details**
The transfer process begins when tankers disable their transponders and dim their lights to avoid detection. They then rendezvous at designated points off Fujairah and Sohar. Once in position, the tankers conduct ship-to-ship transfers, moving oil from smaller vessels to larger carriers. This operation typically takes between 24 to 40 hours. The U.S. military monitors these activities through aerial surveillance, compliance screening, and monitoring, rather than providing direct naval escort.
**Strategic Significance**
The Strait of Hormuz is a critical chokepoint for global oil shipments, with a significant portion of the world’s oil passing through it. Iran’s blockade of this strait posed a substantial threat to global energy markets. By employing these covert transfer methods, the U.S. military has ensured that Gulf energy exports continue to reach international markets, thereby stabilizing global oil prices and maintaining energy security.
**International Reactions**
The U.S. military’s operations have drawn international attention. On June 9, 2026, an Apache helicopter involved in the operation was downed by Iranian forces, leading to retaliatory actions by the U.S. Additionally, India’s foreign ministry lodged a strong protest with the United States following the disabling of the Palau-flagged vessel M/T Settebello, which was suspected of being part of a “shadow fleet” used to smuggle Iranian oil and evade sanctions.
**Conclusion**
The U.S. military’s adoption of Iranian smuggling tactics to facilitate oil transfers underscores the lengths to which nations will go to ensure the uninterrupted flow of energy resources. While effective in maintaining global oil supply, such operations also highlight the complexities and risks associated with maritime energy transport in politically sensitive regions.
