U.S. military operations have established a protective framework in the Strait of Hormuz, enabling a significant increase in oil shipments despite ongoing Iranian attacks in the region. According to industry sources and security officials, the complex mission involves a layered defense system combining air defenses, fighter jets, drones, and naval assets to safeguard vessels navigating the strategic waterway.
This month marks the most intense period of violence in the strait since the onset of the conflict, with at least 25 ships targeted in October, according to data from the U.K. Maritime Trade Operations center. The rising threats have contributed to the sinking of two vessels during the same period, highlighting the hazardous conditions faced by maritime traffic.
Despite these attacks, oil exports have rebounded sharply. Maritime analytics firm Kpler reported that average daily oil exports reached approximately 14 million barrels in the week ending Oct. 18, recovering to about 80% of pre-conflict levels. By comparison, exports had dropped to around 7 million barrels per day in July. U.S. Central Command said more than 1.5 billion barrels of oil have passed through the strait since the summer, underscoring the scale of the shipments secured by U.S. operations.
The 82nd Airborne Division of the U.S. Army leads the mission and operates a joint operations center based in the United Arab Emirates. The UAE Embassy in Washington did not respond to requests for comment regarding its role in the operations.
Daily vessel traffic has increased, with at least 30 ships transiting the strait each day this month. However, risk levels remain high enough that most ships willing to make the journey are state-owned or state-operated, as private companies largely continue to avoid the route even with U.S. protection. Since the intensification of U.S. operations in August, seven seafarers have died and 18 have been injured, according to United Nations figures.
Shipping and industry officials regard the efforts as a critical but temporary measure. One Western security official described the situation in the strait as “completely unsustainable” and noted the reluctance of most liquefied natural gas carriers to transit the area due to the heightened risk of explosion in the event of an attack.
Analysts have offered differing perspectives on the impact of Iranian assaults on shipping. Gregory Brew, an expert on energy and Iran at the Eurasia Group, said Iran’s strategy of maintaining a contested but not fully closed strait serves to keep energy prices elevated, suggesting that while the U.S. has secured important gains, the situation falls short of stabilizing global prices. Conversely, retired Vice Admiral Kevin Donegan, a former commander of the U.S. Navy’s Fifth Fleet, characterized current U.S. operations as more agile and less resource-intensive than similar efforts during the 1980s tanker wars. Donegan described the protection as a “moving sanctuary” that can be deployed flexibly to shield vessels during vulnerable segments of their transit.
Under the current operation, vessels assemble off the UAE coast daily and receive navigation instructions including turning off Automated Identification System transponders to reduce tracking risk. Ships follow designated safe corridors marked by NATO phonetic alphabet checkpoints. Once passing the strait, cargoes are transferred to privately owned tankers in the Gulf of Oman before ships return to the Persian Gulf to reload. This process has created a “shadow fleet” of vessels that operate repeatedly along the route due to the reluctance of other operators to accept the threat.
Donegan noted the emergence of a nascent regional coalition supporting the operations, involving governments in the UAE, Kuwait, and Iraq. He emphasized the importance of sustained diplomatic and military engagement to pressure Iran, stating the goal is to reach a “tipping point” that discourages future attacks.
