U.S. Sailors prepare to refuel a United Arab Emirates Air Force UH-60M Black Hawk helicopter on the flight deck of the guided missile destroyer USS Arleigh Burke (DDG 51) in the Persian Gulf, April 23, 2014. It was the first time the UAEAF landed that type of aircraft aboard a U.S. Navy warship. The Arleigh Burke deployed in support of maritime security operations and theater security cooperation efforts in the U.S. 5th Fleet area of responsibility.
