USS New York (LPD 21), a San Antonio-class amphibious transport dock, is the sixth ship of the United States Navy to be named for the state of New York.

Shortly after 11 September 2001, Governor of New York George E. Pataki wrote a letter to Secretary of the Navy Gordon England requesting that the Navy bestow the name USS New York on a surface warship involved in the War on Terror in honor of September 11's victims. In his letter, the Governor said he understood state names presently are reserved for submarines but asked for special consideration so the name could be given to a surface ship. The request was approved August 28, 2002.

24 tons of the steel used in its construction came from the rubble of the World Trade Center, with seven tons melted down and cast to form the ship's "stem bar," part of the ship's bow.

March 1, 2008 PCU New York was christened in a ceremony at Northrop Grumman Shipbuilding facilities in New Orleans, La. Mrs. Dotty England, the wife of Deputy Secretary of Defense, Gordon England, served as the ship’s sponsor. Cmdr. F. Curtis Jones, of Binghamton, N.Y., is the ship’s first commanding officer.

January 12, 2010 The inspectors discovered the "premature failure" of bearings on the ship’s main propulsion diesel engines during a week long, at-sea examination that followed the New York’s November commissioning. USS New York now must undergo repairs to replace faulty engine parts but is unknown how long will have to stay pierside and how serious the failures are.
