USS Tripoli, embarked 31st Marine Expeditionary Unit arrive in Middle East

U.S. Marines and sailors assigned to the Tripoli Amphibious Ready Group arrived in U.S. Central Command waters on Friday, the command announced.

The group, led by the America-class amphibious assault ship USS Tripoli, departed earlier this month from its homeport of Sasebo, Japan. Also included in the arriving force are the amphibious transport dock ships USS New Orleans and USS San Diego, and the embarked 31st Marine Expeditionary Unit.

The Tripoli group began steaming toward the Middle East after U.S. Defense Secretary Pete Hegseth reportedly approved a CENTCOM request for additional support to help curtail Iran’s regional attacks.

Announcement of the group’s arrival comes one day after a dozen U.S. service members were wounded in an Iranian missile and drone strike on Prince Sultan Airbase in Saudi Arabia, the Wall Street Journal first reported. Two of the 12 personnel are in serious condition.

That strike, which reportedly damaged multiple U.S. refueling aircraft, comes as the U.S. military continues to pour assets into the region.

The Pentagon on Wednesday confirmed elements from the 82nd Airborne Division headquarters and a brigade combat team are slated to deploy to the Middle East. Based out of Fort Bragg, North Carolina, the 82nd acts as the Army’s rapid-response force and is often among the first units sent to respond to emerging crises.

The 31st MEU, meanwhile, includes a ground combat element, which features a battalion landing team — an infantry battalion and combat support elements — of around 1,100 Marines and sailors.

Also included is the MEU’s aviation combat element, which features tiltrotor and fixed-wing aircraft, transport and attack helicopters, ground support assets and air defense teams.

A combat logistics battalion with equipment and personnel capable of sustaining a MEU in austere environments for up to 15 days will also join the effort.

The 11th Marine Expeditionary Unit, part of the Boxer Amphibious Ready Group, has also been rumored to serve as a potential reinforcement. The group deployed in recent weeks and is currently operating in the U.S. 3rd Fleet area of operations in the eastern Pacific.

The U.S. military on Saturday also announced that the aircraft carrier USS Gerald R. Ford, which had been deployed in U.S.-Israeli operations against Iran, pulled into port in Split, Croatia, for maintenance.

Thirteen service members have been killed in action and nearly 300 wounded during Operation Epic Fury, a joint undertaking by U.S. and Israeli militaries against the Islamic Republic that began on Feb. 28.

The majority of the wounded have since returned to duty, according to U.S. Central Command. Prior to Friday’s attack, 10 U.S. troops reportedly remained in serious condition.
