Thousands of people have watched the christening in Louisiana of a US warship built partly from steel salvaged from the World Trade Center.
The twin towers in New York were destroyed in the hijacked planes attack of 11 September 2001.
Friends and families of 9/11 victims were among those at the ceremony for the new amphibious assault ship, the USS New York, in the base of Avondale.
The bow contains 7.5 tonnes of steel taken from Ground Zero.
It also bore a shield with two bars to symbolise the towers and a banner with the slogan Never Forget.
