180214-N-EV253-013 ATLANTIC OCEAN (Feb. 14, 2018) An MH-60S Sea Hawk helicopter assigned to the "Dragon Slayers" of Helicopter Sea Combat Squadron (HSC 11) participates in a replenishment-at-sea with the aircraft carrier USS Harry S. Truman (CVN 75) and USNS Arctic (T-AOE 8). Truman is underway for composite training unit exercise (COMPTUEX), which evaluates the strike group's ability as a whole to carry out sustained combat operations from the sea, ultimately certifying the Harry S. Truman Carrier Strike Group for deployment. (U.S. Navy photo by Mass Communication Specialist Seaman Sara Eshleman/Released)
