Sailors and Marines aboard the USS Iwo Jima participate in a swim call on 18 April 2015. During ‘swim calls’ sailors and marines get to take a casual dip in the sea while onlookers above keep an eye out for sharks and other undersea creatures.
The Gulf of Aden is located in the Arabian Sea between Yemen, on the south coast of the Arabian Peninsula, and Somalia in the Horn of Africa. The region was once a hotbed for piracy but that has subsided in recent years. The USS Iwo Jima is an amphibious assault ship (LHD 7).
