Two outbound tankers were struck by unidentified projectiles in the Strait of Hormuz within 24 hours, and U.S. Central Command disabled its fourth merchant ship since resuming a naval blockade of Iranian ports on July 14 — a three-front squeeze that now exposes operators inside the Persian Gulf, in Hormuz and in the Gulf of Oman alike.

The first strike hit at approximately 1920 UTC on Saturday, October 10, when an outbound tanker took a projectile on its port side, according to UK Maritime Trade Operations. The impact caused a fire onboard. The crew was reported safe, but the extent of damage and any environmental impact remained unknown.

The second incident followed on Sunday, October 11. The company security officer of another outbound tanker reported the vessel had been struck on its port side by an unidentified projectile. UKMTO said the ship sustained damage, but all crew members were safe and no pollution had been reported.

Neither vessel was identified. UKMTO did not attribute responsibility for either attack.

How far has the threat spread?

The weekend strikes cap a violent stretch that has pushed attacks well beyond the Strait itself.

• On Friday, the Panama-flagged crude carrier GEM NO.2, identified by maritime security sources, was struck by a projectile while anchored roughly 13 nautical miles west of Al Jazeera, UAE. The resulting fire was extinguished.
• That strike came two days after another tanker was hit by multiple projectiles off the coast of Qatar — a marked expansion of the danger zone beyond the narrow waterway.

Iran has stepped up attacks and threats against commercial vessels in recent weeks, targeting in particular ships attempting to use routes through Hormuz that Iranian authorities have not authorized. The pattern reinforces concerns that risk is no longer confined to the transiting corridor.

What did the U.S. strike change?

In a statement issued Saturday, CENTCOM said an American fighter jet struck the stern of the Panama-flagged cargo vessel Ocean Molica, also known as Arika Sun, after its crew ignored repeated warnings and attempted to violate the U.S. naval blockade against Iran. The ship had previously departed an Iranian port.

CENTCOM said the precision strike disabled the vessel's propulsion without injuring the crew. The incident marks the fourth commercial vessel disabled since U.S. forces resumed the blockade on July 14.

The command said U.S. forces have also turned around 135 commercial ships and destroyed 10 tankers linked to the Islamic Revolutionary Guard Corps' shadow fleet network during the same period.

For operators, the calculus is now brutally binary: ships attempting to pass through Hormuz face the threat of Iranian attack and intimidation, while vessels calling at Iranian ports risk interception or disabling strikes by U.S. forces. Neither assurance from Washington — that the Strait remains open and under U.S. control — nor the actual tempo of incidents on the water point to de-escalation.

What are authorities telling crews?

UKMTO issued two additional advisories on Saturday. In one, several shipmasters near Ras Al Khaimah, UAE, reported receiving VHF broadcasts directing them to leave their anchorages. In another, UKMTO reported an incident involving a tanker and military forces in the Gulf of Oman, without providing further detail. It was not immediately clear whether that advisory related to the U.S. strike on Ocean Molica.

The U.S.-led Joint Maritime Information Center warned on Thursday that attacks had become more frequent and called for increased vigilance by crews and closer monitoring by the shipping industry.

With strikes now recorded off Qatar and the UAE, continued military activity in the Gulf of Oman, and both Iranian projectiles and U.S. disabling strikes in play, commercial operators transiting the region face a widening threat set that no single routing decision fully mitigates.
