President George W. Bush yesterday commissioned a new aircraft carrier named for his father, former President George H.W. Bush, before a crowd of 18,000 in a ceremony that was part Navy tradition and part family reunion. The younger Bush, 10 days from the end of his presidency, joined his father at the Norfolk Naval Base to usher the $6.3 billion carrier George H.W. Bush into the Atlantic Fleet. “I ask that God protect this ship and bring her only victory and peace,“ the president said.
