A U.S. Marine Corps CH-53E Super Stallion helicopter assigned to the 22nd Marine Expeditionary Unit (MEU) crashed at 2:00 p.m. (GMT), September 1, at sea in the Gulf of Aden as it attempted to land aboard USS Mesa Verde, the U.S. Navy reports.
All 25 persons aboard the helicopter; 17 Marines and eight Navy Sailors, were safely recovered and are aboard USS Mesa Verde. Personnel who sustained minor injuries in the crash were treated aboard USS Mesa Verde.
The crash was reportedly not a result of hostile activity. According to the U.S. Navy, the aircraft was transferring the Marines and Sailors back to USS Mesa Verde from training ashore in nearby Djibouti.
The Navy and Marine Corps have announced the investigation into the cause of the crash.
USS Mesa Verde with embarked elements of the 22 MEU is part of the Bataan Amphibious Ready Group currently on a scheduled deployment to the U.S. Central Command Area of Responsibility where it is conducting maritime security operations.
