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 Sara Eshleman/Released)
