A very large crude carrier (VLCC) belonging to the National Iranian Tanker Company successfully evaded the U.S. Navy and reached the Asia-Pacific region while carrying more than 1.9 million barrels of crude oil worth nearly $220 million, according to the monitoring service TankerTrackers.com.

In a post on X, the service emphasized that the vessel is "huge" and was last seen off the coast of Sri Lanka more than a week ago.

The tanker is currently crossing Indonesia’s Lombok Strait toward the Riau Archipelago.

TankerTrackers.com reports that the supertanker was in Iranian waters on April 13, when the U.S. Navy announced a blockade of Iranian ports.

According to the report, the vessel has not transmitted Automatic Identification System (AIS) signals since March 20, when it left the Strait of Malacca and headed for Iran.

The report came after Iranian media said on April 29 that at least 52 Iranian vessels had breached the American blockade.

Meanwhile, the U.S. military said that since the start of the blockade, they had forced about 41 Iran-linked vessels to change course.

U.S. officials say the blockade is working and has cost Iran billions of dollars in revenue. The United States says Iran cannot export oil and will be forced to store it until storage capacity runs out and production stops, Al Jazeera reports.
