Iranian supertanker carrying $220 million in crude breaks through US naval blockade

An Iranian supertanker loaded with more than 1.9 million barrels of crude oil has successfully navigated past the American naval blockade and reached Southeast Asian waters, in one of the most direct challenges yet to Washington's efforts to choke off Tehran's petroleum exports. The vessel, a very large crude carrier operating under the name HUGE and registered under IMO number 9357183, is operated by the National Iranian Tanker Company and carries a cargo valued at close to $220 million. Maritime tracking firm TankerTrackers.com announced the breach on Sunday, reporting that the ship had last been spotted off Sri Lanka more than a week earlier and was transiting the Lombok Strait in Indonesia toward the Riau Archipelago.

The HUGE had not transmitted automatic identification system signals since March 20, when it departed the Strait of Malacca toward Iran. It was apparently in Iranian waters on April 13, the day the blockade was formally announced. By switching off its transponder and taking less-monitored maritime routes, the vessel appears to have evaded detection by American naval forces patrolling the region. The cargo it carries is substantial enough to supply a mid-sized refinery for several days, illustrating the tangible economic value at stake in each successful run through the blockade perimeter.

The HUGE's passage is not an isolated incident. Iranian state media claimed on April 29 that 52 Iranian vessels — 31 tankers and 21 cargo ships — had broken through the American-imposed blockade within a 72-hour window. Earlier in April, freight tracking data from Vortexa indicated that at least 34 Iran-linked tankers had circumvented the blockade since it took effect on April 13, with 19 departing the Persian Gulf and 15 entering from the Arabian Sea. An investigation published on April 30 detailed how Iran's shadow fleet employs false flags, shell companies, and the deliberate disabling of location systems to evade standard maritime controls, with some vessels conducting ship-to-ship cargo transfers at sea to avoid calling at Iranian ports, which would constitute a clear violation of the blockade terms.

American officials have pushed back against characterizations of widespread evasion. President Donald Trump described the blockade as a "resounding success" and claimed Washington held the Strait of Hormuz under "total control." The Pentagon denied earlier reports of 26 Iranian vessels having broken through, and the US military stated it had intercepted or turned back approximately 41 Iran-linked ships since enforcement began. Washington has maintained that the blockade has cost Tehran billions of dollars in lost revenues and could eventually force Iran to curtail production as onshore storage capacity approaches saturation. Officials have also clarified that the operation targets Iranian ports and coastline rather than imposing a complete closure of the Strait of Hormuz, through which roughly 20 percent of global oil supply flows. The successful transit of the HUGE, however, underscores the persistent difficulty of enforcing a maritime blockade across vast ocean distances against an adversary that has spent decades refining techniques to circumvent international sanctions.
