The 684-foot, $1.2-billion warship USS New York is actually made of New York. At least, 7.5 tonnes of salvaged steel from the Twin Towers. Watch it come back home, under the eyes of the Lady of the Harbor:

The USS New York is a San Antonio-class amphibious assault vessel, which can carry 800 marines with their helicopters. The steel from the World Trade Center was used for its bow. If you are in New York, you can see it today near Zone Zero, on the south tip of Manhattan. [USS New York via Times Online]
