I saw the USS New York from the ferry on Saturday. Though it could be mistaken by the layman for an aircraft carrier, the vessel is actually classified as an amphibious transport dock.
Shortly after 11 September 2001, Governor of New York George E. Pataki wrote a letter to Secretary of the Navy Gordon R. Englandrequesting that the Navy bestow the name USS New York on a surface warship involved in the War on Terrorism in honor of the victims of the September 11 attacks.
The contract to build the New York was awarded to Northrop Grumman Ship Systems of New Orleans, Louisiana, in 2003. TheNew York was under construction in New Orleans at the time of Hurricane Katrina in 2005.
7.5 short tons (6.8 t) of the steel used in the ship’s construction came from the rubble of the World Trade Center; this represents less than one thousandth of the total weight of the ship. wikipedia
The vessel was christened 3/1/08 in New Orleans and commissioned 11/7/09 in New York. It is the 7th US Navy vessel to bear the name New York.
