Nimitz-class

In the United States Navy, the ten ships of the Nimitz-class are its major aircraft carriers. The Gerald R. Ford-class carriers, entering construction, will supplement them. They followed the one-of-a-kind USS Enterprise (CVN-65), although some conventionally powered carriers were built after the 1961 Enterprise. By now, all of the conventionally powered aircraft carriers of the U.S. Navy have been decommissioned, leaving only nuclear-powered carriers for the U.S.

Ships

This class of aircraft carriers is named after its lead ship, the USS Nimitz. That ship, in turn, memorializes Fleet Admiral Chester W. Nimitz.

• USS Nimitz (CVN 68)
• USS Dwight D. Eisenhower (CVN 69)
• USS Carl Vinson (CVN 70)
• USS Theodore Roosevelt (CVN 71)
• USS Abraham Lincoln (CVN 72)
• USS George Washington (CVN 73)
• USS John C. Stennis (CVN 74)
• USS Harry S. Truman (CVN 75)
• USS Ronald Reagan (CVN 76)
• USS George H.W. Bush (CVN 77)

CVN 77, USS George H.W. Bush, is intended as a transition between the Nimitz and Ford classes. New features include:

1. Passive Jet Blast Deflector: Redesigns and new materials mean reduced maintenance costs.
2. Redesigned island: Improve flight deck access and reduce signature and electronic self-interference.
3. Other Signature Reduction: Curved flight deck edges, enclosed antenna farms, smaller islands and internal aircraft elevators add up to maximum stealth.
4. Aircraft Pit Stop: Semi-automated refueling and servicing in a new configuration and deck location provides faster, more efficient airwing pit stops and requires fewer people.
5. Redesigned Hangar Deck: New designs reduce clutter.
6. Manpower Reductions: Technology, space rearrangement, operational procedure changes, advanced sensor technologies and condition-based maintenance systems all allow for a smaller, specially-trained crew. Material movement devices, semi-autonomous, gravity compensated weapons handling devices, damage control automation systems and components will reduce the ship's crew and costs.
7. Reconfigurable Spaces: Life-of-the-ship modular construction designs provide flexibility and reduce cost.
8. Expanded Bandwidth: More onboard (Local area network_ and offboard capability gives the ship a communications edge.
9. Zonal Electrical Distribution Systems: Isolate the potential for problems and minimizes the effect on the rest of the ship; crew laptops and other personal electronics, on- and off-duty, have greatly increased electrical demand
