U.S. Stealth Escort Operation Keeps Oil Flowing Through Hormuz Amid Iranian Attacks

Since May 2026, the United States has run a covert escort mission that shepherds commercial tankers through the Omani half of the Strait of Hormuz. The effort uses naval ships, helicopters and aircraft to intercept Iranian attacks while keeping the vessels’ radars and transponders off-line. Analysts estimate that the protected routes moved roughly five million barrels of crude each day in July, and U.S. Energy Secretary Chris Wright later said the flow may be as high as nine million barrels daily. The operation has enabled more than 1,000 ships to cross despite missile and drone strikes that have damaged at least 15 vessels and caused three deaths and 16 injuries.

Before the conflict, about 15 million barrels of oil and roughly 130 vessel transits passed through Hormuz each day. Iran claims control of the Iranian side of the strait and has repeatedly targeted ships, using the waterway as an “energy weapon.” The war has cut pre-war oil flows by roughly one-third, prompting U.S. intervention to blunt a rise in global oil prices.

• Pre-war baseline: ~15 million barrels per day; ~130 daily transits.

• Current VLCC traffic: Kpler data shows an average of two to three VLCCs per day since July 7, compared with about eight VLCCs daily before the war.

• Barrel estimates:

• New York Times reports ~5 million barrels daily via U.S.-protected routes in July.

New York Post

• Chris Wright estimates ~9 million barrels daily.

• Ship movements: Approximately 70 ships crossed in the first three weeks of the mission; over 1,000 ships have been escorted overall.

• Casualties: The International Maritime Organization records at least 15 ships damaged since June; three crew members killed and 16 injured.

U.S. Energy Secretary Chris Wright said the United States is “growing” its ability to escort and export products from the region, noting that Iran’s “giant arsenal” is causing difficulties but its impact is waning. Iranian officials have not issued a direct response in the sourced material.

Sources differ on total oil volumes. The New York Times cites about five million barrels per day, while Wright claims nine million, and later U.S. statements reference up to 15 million barrels daily, including pipeline exports and “dark” transits. Kpler reports only 2-3 VLCCs per day, yet many vessels turn off AIS signals, making precise counts difficult.
