U.S. President Donald Trump departs after commissioning the aircraft carrier USS Gerald R. Ford during a ceremony 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)
