The two unidentified ships in CENTCOM's earlier strike footage have become three named vessels. In a statement carried by AFP, US Central Command said it "permanently disabled the IRGC crude oil carriers M/T Downy off the coast of Kharg Island and M/T Stark 1 near Jask," and that American forces "also completely destroyed the unladen crude oil carrier M/T Kylo... in the Gulf of Oman, striking the vessel in multiple critical locations to render it inoperable after the crew was directed to abandon ship" [1].

CENTCOM said the strikes followed Iran's "failed attacks" — accusing the IRGC of unsuccessfully firing at American warships — and described the three tankers as part of a "multibillion-dollar shadow network that funds the IRGC and its regional proxies." Video it posted showed large fireballs and billowing flames after projectiles hit the ships. Commander Admiral Brad Cooper said: "If you shoot at two of our ships, we will impose an even higher economic cost -- taking out three of yours" [1].

This is CENTCOM's own account, not independent verification of the vessels' condition. Iranian media had reported several explosions earlier on Saturday near Kharg Island, which is consistent with at least one of the locations but does not confirm the damage claims [1].

The escalation lands inside a six-month war in which, as AFP puts it, Iran keeps a stranglehold on the Strait of Hormuz while Washington presses a counter-blockade of Iranian ports. Washington has also announced sanctions on entities with financial links to Iran. Tehran said on Thursday its forces attacked US bases in Kuwait and the UAE, vowing revenge for civilian deaths at a wedding it blames on a US strike; Vice President JD Vance said that report was being investigated but that he was "sceptical." Vance has also said he "wouldn't call it a war" and that "there is no active shooting," while Trump called the conflict "small potatoes" [1].

For shipping, the significance is that the "tanker for tanker" approach reported earlier this week now has named hulls and an explicit economic-cost doctrine attached to it, with strikes reaching into the Gulf of Oman approach to the strait.
