The Nimitz-class supercarriers are a line of nuclear-powered aircraft carriers in service with the United States Navy, are the largest capital ships in the world, and these supercarriers are considered to be a hallmark of American superpower status. A total of nine ships of the class have been completed and at least one more is being built.
USS Nimitz (CVN-68) is an aircraft carrier in the United States Navy, the lead ship of its class. She is one of the largest warships in the world. She was laid down, launched and commissioned as CVAN-68, but was redesignated CVN-68 (nuclear-powered multimission aircraft carrier) on 30 June 1975 as part of the fleet realignment of that year.
The keel of USS Nimitz was laid down 22 June 1968 by Newport News Shipbuilding in Newport News, Virginia, and she was commissioned 3 May 1975. Since then, USS Nimitz has been deployed world wide in the service of the US Navy. She remains in service.
