A new U.S. Navy ship built with metal from the World Trade Center arrived in New York City on Monday near the site of the 2001 terror attacks.

The U.S.S. New York was welcomed by a 21-gun salute and families of the victims of the 9/11 attacks.

Rosaleen Tallon lost her firefighter brother Sean on Sept. 11, 2001 and she applauded the new ship.

"It's a transformation ... from something really twisted and ugly," she said. "I'm proud that our military is using that steel."

The $1 billion battleship gray vessel contains about 7.5 tons of steel from the fallen World Trade Center towers.

And at 684 feet long, the ship can carry as many as 800 Marines.

The U.S.S. New York will have its official commissioning ceremony on Saturday, Nov. 7.
