The Nimitz class supercarriers are the largest capital ships in the world. All of the ships in this class are nuclear-powered carrier vessels. These ships 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 to indicate nuclear-powered propulsion. The number after the "CVN" means that this is the 68th "CV", or aircraft carrier.
Nimitz (CVN-68), the lead ship of the class, was commissioned in 1975. As of 2006, George H. W. Bush (CVN-77), the tenth and last of the class, is being built by Northrop Grumman Newport News and will enter service in 2008. Bush will be the first transition ship to a new class of carriers (CVN-21) to start construction in 2007 and will incorporate new technologies including a new multi-function radar system, volume search radar and open architecture information network, and a significantly reduced crew requirement. To lower costs some new technologies were incorporated into Ronald Reagan, though not nearly as many as will be involved with Bush.
Because of construction differences between the first three ships (Nimitz, Eisenhower and Vinson) and the latter seven (from Theodore Roosevelt on), the latter ships are sometimes called Theodore Roosevelt-class aircraft carriers, though the U.S. Navy officially holds no difference between the two groups. As the older ships come in for Refueling and Complex Overhaul (RCOH), they are upgraded to the standards of the latest ships, virtually eliminating differences.
By tonnage, Nimitz class compose by far the largest class of carriers ever built. When Bush is completed, the ten ships of the class will total just under a million tons combined displacement.
Nimitz was the first to undergo its initial refueling during a 33-month Refueling and Complex Overhaul (RCOH) at Newport News Shipbuilding in Newport News, Virginia, in 1998. Dwight D. Eisenhower was next, completing RCOH in 2005. Carl Vinson began RCOH in late 2005.
