Hi-tech Warship USS New York, LPD-21, whose stem bow has been constructed out of the seven and a half tons of steel recovered from World Trade Center's twin towers site after the 9/11 catastrophe, has finally sailed today for its namesake city. Built in New Orleans, USS New York at the moment is heading towards NYC where it is going to be commissioned next month. It was christened "New York" to honor the 9/11 attack victims in that city.
