U.S. military forces disabled a vessel on Friday, May 29, 2026, after it attempted to breach a naval blockade of Iranian ports [1], [2].

The incident marks a significant escalation in the enforcement of maritime restrictions in a contested region, signaling a willingness by the U.S. to use kinetic force to maintain the blockade.

U.S. Central Command (Centcom) said that an aircraft fired a Hellfire missile [3] into the engine room of the ship to stop its progress [1], [2]. The vessel was flying a Gambian flag [1]. Some reports identified the ship as the Lian Star [3].

The engagement occurred in the Gulf of Oman, though some reports place the strike within the Strait of Hormuz [1], [3]. The U.S. military said the vessel ignored more than 20 warnings [2] before the strike was authorized.

Centcom officials said the action was necessary because the ship continued its attempt to enter the restricted zone despite repeated commands to stop [1], [2]. The use of a precision-guided missile was intended to disable the ship's propulsion without sinking the vessel or causing unnecessary casualties [3].

The region has seen increased naval activity as the U.S. maintains its blockade of Iranian ports to restrict the movement of goods, and personnel [1]. This specific encounter follows a series of standoffs between international shipping and U.S. naval assets in the area [2].

The use of a Hellfire missile to disable a civilian-flagged vessel underscores the high tension surrounding the blockade of Iranian ports. By targeting the engine room rather than the hull, the U.S. military demonstrated a calibrated use of force intended to enforce maritime law while avoiding a total loss of life or a sunken ship, which could further destabilize the Strait of Hormuz.
