The Nimitz-class supercarriers, a line of nuclear-powered aircraft carriers in service with the United States Navy, are the largest capital ships in the world, and are considered to be a hallmark in the superpower status of the United States of America. These aircraft carriers are numbered with consecutive hull numbers starting with CVN-68. The letters CVN denote the type of ship: "CV" is the hull classification symbol for aircraft carriers, and "N" indicates nuclear-powered propulsion. The number after the CVN means that this is the 68th "CV", or large aircraft carrier.
Nimitz (CVN-68), the lead ship of the class, was commissioned on May 3, 1975. George H. W. Bush (CVN-77), the tenth and last of the class, was built by the Newport News Shipbuilding Company, and entered naval service on January 10, 2009. The George H.W. Bush is the first transition ship to the new Gerald R. Ford class, the first ship of which began construction in 2007 and will incorporate new technologies including a new multi-function radar system, volume search radars, an open architecture information network, and a significantly reduced crew requirement. To lower costs, some new technologies were also incorporated into the Ronald Reagan, the previous carrier to the George H.W. Bush.
Because of construction differences between the first three ships (Nimitz, Dwight D. Eisenhower, and Carl Vinson) and the latter seven (from Theodore Roosevelt on), the latter ships are sometimes erroneously called Theodore Roosevelt-class aircraft carriers, though the U.S. Navy considers them all to be in one class.[1] As the older Nimitz carriers come in for Refueling and Complex Overhaul (RCOH), they are upgraded to the standards of the latest ships.[2] The Nimitz was the first ship of the class to undergo her initial refueling, during a 33-month RCOH at the Newport News Shipbuilding Company in Newport News, Virginia, in 1998. The Dwight D. Eisenhower was next, completing its RCOH in 2005. The Carl Vinson began its RCOH in late 2005. The USS Abraham Lincoln entered the large drydock at Puget Sound Naval Shipyard on September 8, 2006, but left ahead of schedule on December 18.[2]
By tonnage, the Nimitz-class warships are the largest aircraft carriers built so far, holding the world record for displacement of any naval war vessel. The ten ships of the class total just under a million tons in combined displacement.
