Earlier on Thursday, US Marine Corps Harrier jets flying from the Boxer joined aircraft operating from the aircraft carrier Harry Truman strike group in the Mediterranean Sea.
"This marks the first naval aviation combat strike missions of Operation Inherent Resolve launched from Navy warships in two different operational theaters," the Navy stated.
On June 3, the Truman strike group launched its first sorties from the eastern Mediterranean Sea, and has conducted 148 combat sorties while operating from the US 6th Fleet.
The Boxer Amphibious Ready Group (ARG) entered the US 5th Fleet on April 5. Military personnel in the ARG team normally support theatre security cooperation efforts and conducting maritime security operations throughout the 5th Fleet, according to the Navy.
