U.S. Marines move humanitarian and disaster relief supplies to load them into a Marine Corps CH-46E Sea Knight helicopter on the flight deck of the amphibious assault ship USS Essex (LHD 2) off the coast of Hachinohe in northeastern Japan on March 21, 2011. The Marines are working in support of Operation Tomodachi, the U.S. military's humanitarian and relief effort in response to the 9.0-magnitude earthquake and tsunami that struck Japan on March 11.
