PACIFIC OCEAN (Oct. 6, 2016) - Sailors assigned to the USS Nimitz (CVN 68) sweep the deck in the hangar bay after testing the ship's aqueous film forming foam as part of sea trials. Nimitz is underway conducting sea trials as part of the completion of a 20-month extended planned incremental availability. Once Nimitz completes sea trials, the ship will begin a training and qualification cycle in preparation for an upcoming 2017 deployment. (U.S. Navy photo by Petty Officer 2nd Class Holly L.
