ARABIAN SEA (Feb. 2, 2011) A Sailor stands watch on the fantail of the aircraft carrier USS Carl Vinson (CVN 70) as bioluminescent organisms and aircraft on final approach light the night around her. The Carl Vinson Carrier Strike Group is deployed supporting maritime security operations and theater security cooperation efforts in the U.S. 5th Fleet area of responsibility.
