U.S. Marines boarded the Iranian-flagged oil tanker M/T Celestial Sea in the Gulf of Oman on Wednesday [1].
The interception is part of a larger naval blockade designed to pressure Iran into reopening the Strait of Hormuz. This operation marks a continued escalation of maritime tensions in a region critical to global energy supplies.
Personnel from the 31st Marine Expeditionary Unit [2] conducted the boarding after the vessel was suspected of attempting to violate the blockade. The tanker was intercepted near the Strait of Hormuz, a narrow waterway that serves as a primary transit point for oil exports [3].
The operation is the latest in a series of enforcement actions. To date, the U.S. military has redirected 91 commercial ships [4] as part of the blockade efforts. Additionally, the military has disabled four vessels [4] during the ongoing operation.
U.S. officials said the blockade is intended to force a diplomatic or operational shift from Iran. The Trump administration has used these maritime restrictions to press for a deal regarding the regional security of the strait [5].
Following the boarding, the U.S. military redirected the vessel. The action underscores the high level of surveillance and active interdiction currently occurring in the Gulf of Oman [6].

The boarding of the M/T Celestial Sea demonstrates the U.S. military's willingness to use direct kinetic intervention to maintain the blockade. By redirecting nearly 100 ships and disabling others, the U.S. is utilizing economic and logistical strangulation as a tool of diplomacy to ensure the Strait of Hormuz remains open to international traffic.
