Nimitz Carrier Puzzle

USS Nimitz (CVN-68) is a supercarrier of the United States Navy, and is the lead ship of her class. She is one of the largest warships in the world. She was laid down, launched and commissioned as CVAN-68 but she was redesignated CVN 68 (nuclear-powered multimission aircraft carrier) on 30 June 1975 as part of the fleet realignment.

The ship was named for World War II Pacific fleet commander Chester W. Nimitz, who was the navy’s third fleet admiral. Unlike all of the subsequent Nimitz class aircraft carriers, Nimitz only uses her namesake's surname as is common for naval officers. She is also the first carrier of her class and the most recent supercarrier in service not to be named for someone who held elected office in the United States.

Nimitz had her homeport at Naval Station Norfolk until 1987, when she was relocated to Puget Sound Naval Shipyard in Bremerton, Washington. Following her Refueling and Complex Overhaul in 2001, her homeport was changed to NAS North Island in San Diego, California. The home port of Nimitz was again moved to Everett, Washington, in 2012. This move is expected to save the Navy $100 million.[3]
