USS New York (warship built with steel salvaged from World Trade Center) is launched

NEW ORLEANS — Peering through thick fog, hundreds stood on the banks of the Mississippi River early Tuesday and cheered as the latest piece of naval history cut through the haze and belched its horn.

The onlookers waved flags at the New York, a freshly built 684-foot Navy warship slowly making its way to New York City, where it will be commissioned in early November and renamed the USS New York.

A ship built of salvaged steel from the World Trade Center is to be reunited with the city it was named after.

The USS New York embarked on its maiden voyage on Tuesday from Louisiana, where it was built, and is set to arrive in New York harbour on 2 November.

The warship will be welcomed by a formal ceremony to honour those killed in the 11 September 2001 attacks, which destroyed the World Trade Center.

Celebrations end on 7 November with the US Navy's commissioning of the ship.
