A Panamanian-flagged container ship was targeted in the Gulf of Oman on Tuesday, August 11, after attempting to breach the U.S. naval blockade of Iranian ports, according to maritime security sources and a U.S. official.

Reuters, citing British maritime risk management firm Vanguard and a naval security source, reported that the container vessel Vela Nova was struck while navigating the Gulf of Oman. Initial assessments by these sources suggested that the vessel may have been hit by a missile.

Concurrently, The Wall Street Journal cited a U.S. official as stating that a U.S. military helicopter fired upon the vessel’s rudder after the crew ignored warnings to stop and refrain from violating the blockade on Iranian ports.

Targeting a ship’s rudder—the underwater vertical mechanism responsible for steering - disables its maneuverability and navigation control. Following the engagement, crew members reportedly attempted to transfer to another nearby civilian vessel.

Discrepancies remain between initial reports regarding the precise weapon used, with maritime security firms citing a potential missile strike, while the U.S. official specified helicopter gunfire directed at the rudder. No casualty figures or detailed damage assessments have been released, and the current status of the vessel remains unconfirmed.
