March 13 (UPI) — The USS Tripoli, and the 2,500 Marines on the amphibious assault ship, are headed to the Middle East to bolster U.S. military power there as the war in Iran enters its third week.

The Tripoli, along with Marines of the 31st Marine Expeditionary Group, had been operating in the Philippine Sea but is now headed west south of Taiwan through the Luzon Strait, USNI News reported.

Although the Tripoli had been with the USS San Diego and USS New Orleans in the Philippine Sea, it is not clear if the San Diego and the New Orleans are also being moved closer to Iran.

As Iran has closed the Strait of Hormuz to most traffic, and is targeting vessels that transit it, the move comes as U.S. Central Command asked the Pentagon for additional military options in the conflict, Axios reported.

The 31st MEU can conduct ground operations, which have not been announced but have not been ruled out, according to the Trump administration.

The deployment comes as President Donald Trump said he is considering sending U.S. Navy vessels to escort shipping vessels through the strait, the military is planning to take out anti-ship missiles that have been sent by Iran to the area.

CENTCOM is particularly focused on ensuring freedom of navigation in the straight, Joint Chiefs of Staff Chair Gen. Dan Caine told reporters on Friday, which “means going after Iran’s mine-laying capability and destroying their ability to attack commercial vessels.

Oil prices have surged over the last week after Iran shut down the strait, though Caine noted that some traffic is moving through it.

Defense Secretary Pete Hegseth also said Friday that the military is “dealing with” Iranian attacks on the strait, saying that “we have been dealing with it and don’t need to worry about it.”

Hegseth added that as the military campaign continues and Iran’s military capabilities weaken, the United States has also been taking out Iranian defense companies to prevent the ability to build more weapons.
