The U.S. military is orchestrating a secretive ship-to-ship oil transfer operation near the Strait of Hormuz to bypass an Iranian-led blockade that has disrupted global energy supplies. Since early May, at least 116 vessels have participated in the initiative, which utilizes aerial surveillance and drone monitoring to guide tankers through the Gulf of Oman with disabled transponders, according to shipping data and satellite imagery reviewed by Reuters.
How does the U.S. military manage these oil transfers?
The operation relies on a “dark” navigation technique—sailing with transponders off and lights dimmed—to shield tankers from Iranian observation. According to eight sources, including a private security contractor, the U.S. military controls the flow by assigning transit windows and monitoring progress through a series of waypoints. Tankers are required to stagger their departures, maintaining gaps of 3,000 to 4,000 meters to avoid collisions while operating in the dark. Before receiving clearance, operators must submit to a compliance review process managed by the U.S. Navy’s Naval Cooperation and Guidance for Shipping office in Bahrain, which includes full disclosure of cargo documentation and beneficial ownership.
What is the role of the Apache helicopter in this mission?
The U.S. military’s involvement in the region recently drew international attention following the June 9 downing of an Apache helicopter by Iranian forces. Four sources, including a former U.S. official, confirmed the Apache was actively involved in the mission at the time of the attack. While the U.S. defense official stated that no Central Command forces are currently participating in offshore ship-to-ship transfers, satellite imagery from the day of the incident shows six pairs of tankers clustered near the port of Sohar, a known hotspot for the operation. The downing of the aircraft triggered retaliatory U.S. bombings, highlighting the volatile environment surrounding these energy corridors.
How does this compare to Iran’s own shipping tactics?
The U.S.-led operation mirrors the “dark fleet” techniques historically pioneered by Iran to evade international sanctions. However, the scale of the two operations differs significantly. While Iran typically manages single pairs of ships to maintain a low profile, the U.S.-led effort involves mass transfers to keep Gulf energy exports moving on a larger scale. According to calculations based on satellite imagery through June 11, at least 90 million barrels of crude oil and petroleum products have moved through this network since the project began in early May.
What are the risks to global energy markets?
The closure of the Strait of Hormuz, which normally facilitates the passage of one-fifth of global oil consumption, has created the most significant energy supply disruption in modern history. According to Noam Raydan, a senior fellow at the Washington Institute, the U.S.-led transfer system is a “temporary solution amid exceptional times.” The risk remains high; vessels operate in areas where the Islamic Revolutionary Guard Corps threatens drone and missile strikes. Despite these dangers, major operators like Greece-based Dynacom Tankers Management have signaled a willingness to continue, citing a historical tradition of “breaking blockades.”
Frequently Asked Questions
- Are U.S. military personnel on the tankers? No. According to Reuters’ findings, there is no indication that U.S. military personnel are directly involved in the oil transfers themselves; they provide surveillance and compliance screening from a distance.
- Why are the ships sailing with transponders off? To avoid detection by Iranian forces who monitor the Strait of Hormuz. By sailing “dark,” the tankers attempt to mask their movements and the source of their cargo.
- Is this a permanent solution? Industry analysts, including Noam Raydan, characterize the operation as a temporary measure to mitigate the impact of the Iranian blockade on global energy prices.
