U.S. Navy sailors stand in the audience as President Donald Trump participates in the commissioning ceremony of the aircraft carrier USS Gerald R. Ford at Naval Station Norfolk in Norfolk, Virginia, U.S., July 22, 2017. The new carrier is the lead ship of the Ford-class of "super -carriers", the first new class in more than 40 years, and will replace the current Nimitz-class carriers. The carrier, named after the nation's 38th president, has suffered a series of cost overruns and delays that added up to $12.9 billion. (Photo/Agencies)
