Muscat: A Super Stallion US Marine helicopter carrying 25 US service members crashed in the Gulf of Aden on Tuesday but all aboard were rescued, according to the US Navy.
Seventeen Marines and eight sailors were aboard the CH-53E Super Stallion helicopter when it crashed as it attempted to land on the USS Mesa Verde.
All were aboard the ship following the incident with some personnel received treatment for minor injuries.
The Navy said the helicopter was transporting troops from training in nearby Djibouti.
The crash was not caused by any hostile activity, according to the military. The cause is being investigated.
Defence Secretary Chuck Hagel ordered the USS Mesa Verde, an amphibious transport dock ship based at Norfolk, Virginia, into the regional waters earlier this summer as concern grew over the Islamic State terrorist group's advance on Iraq's capital, Baghdad.
The ship transports and lands Marines and other troops, their equipment and supplies, aided by helicopters and vertical takeoff and landing aircraft.
