Aviation Boatswain's Mate (Fueling) Airman Travis Roach

Aviation Boatswain's Mate (Fueling) Airman Travis Roach takes a fuel sample for a flash point, water and sediment test during a replenishment-at-sea (RAS) between the U.S. Navy's forward-deployed aircraft carrier USS George Washington (CVN 73) and Military Sealift Command fleet replenishment oiler USNS John Ericsson (T-AO 194). During the RAS, ships from Commander, Task Force 70 and 73 participated in a simulated submarine threat exercise for Valiant Shield 2014. Valiant Shield is a U.S.-only exercise integrating an estimated 18,000 Navy, Air Force, Army and Marine Corps personnel, more than 200 aircraft and 19 surface ships, offering real-world joint operational experience to develop capabilities that provide a full range of options to defend U.S. interests and those of its allies and partners.
