In a recent operation highlighting the enforcement of Washington’s maritime restrictions on Iran, U.S. Marine forces boarded a commercial cargo ship in the Arabian Sea on Tuesday that had been flagged for potential violation of the American blockade of Iranian ports, U.S. military officials confirmed.
Following the boarding operation, Central Command—the U.S. military unified combatant command that oversees all American military assets across the Middle East—announced via a post on the social platform X that the M/V Blue Star III had been cleared to continue its journey. The release came after a full search of the vessel confirmed that it had no planned port calls at any Iranian facility along its scheduled route.
The command’s statement emphasized that U.S. maritime forces are maintaining a persistent presence across the region to uphold the blockade. To date, military officials report that 39 vessels have already been redirected from their original courses to ensure full compliance with the restrictions.
Accompanying the announcement was a short video clip capturing the operation. The footage shows a military helicopter hovering low over the Blue Star III’s deck while Marines fast-roped down onto the stacks of shipping containers that line the vessel’s cargo hold.
The current maritime standoff in the region follows a series of escalating developments. After the U.S.-Israeli joint air campaign against Iran launched on February 28, Iranian military forces moved to close the Strait of Hormuz—the strategically critical waterway that carries roughly a fifth of the world’s daily oil and global natural gas shipments. This closure upended one of the world’s busiest and most economically vital maritime chokepoint.
Washington rolled out its official blockade of Iranian ports after a round of regional peace negotiations held in Pakistan failed to deliver any breakthrough towards de-escalation. U.S. forces began actively enforcing the new maritime restrictions on April 13.
Speaking to reporters earlier this month, U.S. Secretary of Defense Pete Hegseth stated that the blockade will remain in place “as long as it takes” to achieve American policy goals. General Dan Caine, the highest-ranking active-duty U.S. military officer, further clarified that the restrictions “applies to all ships, regardless of nationality, heading into or from Iranian ports.”
