# U.S. Marines Board Iranian-Flagged Touska After Spruance Disables Ship in Hormuz Operation
U.S. forces seized control of an Iranian-flagged cargo ship after it ignored repeated warnings in the Strait of Hormuz area, marking what the supplied evidence describes as the first direct American action against a ship since a blockade was announced. The event date is 2026-04-19. According to Task and Purpose, the Arleigh Burke-class destroyer USS Spruance disabled the vessel Touska and Marines from the 31st Marine Expeditionary Unit then boarded it.
The report says the ship was under U.S. Treasury sanctions and was sailing toward Bandar Abbas, Iran, when it was intercepted. U.S. Central Command stated that the crew failed to comply with warnings over a six-hour period. After that, the destroyer ordered the vessel’s engine room evacuated and fired several rounds from its 5-inch gun into the engine room, disabling its propulsion. The Marines then rappelled onto the vessel and took custody.
The episode matters because it moves the Strait of Hormuz dispute from warnings and deterrence into physical interdiction. The packet says American forces had already forced more than 20 ships to turn back before this incident, but the Touska case was the first to involve direct seizure. That makes it a meaningful escalation, not just another maritime standoff.
The available evidence points to a wider blockade environment around Iranian waters. Task and Purpose reports that the U.S. had announced a blockade for ships trying to leave or reach Iranian ports, in response to Iran limiting access to the strait. The article also says two Indian tankers were fired on by Iran’s Islamic Revolutionary Guard Corps the day before, and that Iranian authorities said they would reimpose strict control over the waterway. Those details help explain why the U.S. treated the Touska as a non-routine target.
CENTCOM’s account, as summarized in the packet, emphasizes repeated attempts to communicate before force was used. That sequence matters because it shows the boarding was presented as a response to noncompliance, not a surprise operation. The source also includes footage from the USS Spruance showing the destroyer sailing near the cargo ship and firing on it. Even so, the evidence does not say what will happen to the ship, its crew or any cargo. Those questions remain unresolved in the supplied material.
The scale of the U.S. posture in the region is also notable. The Spruance was operating with the USS Abraham Lincoln Carrier Strike Group in the Arabian Sea, while the USS Tripoli Amphibious Ready Group, carrying roughly 2,200 Marines from the 31st Marine Expeditionary Unit, was nearby. That force structure helps explain why U.S. commanders could move from warning shots and surveillance to a boarding action.
In practical terms, the seizure shows how quickly the shipping crisis around Hormuz has become a live military contest. A commercial ship was told to stop, then disabled, then boarded. Whether it becomes a one-off enforcement case or the start of a more frequent pattern will depend on how both sides respond. What is clear from the packet is that the United States has now used force at sea to stop a vessel in this campaign.
