| | CVN-68 Nimitz-class - Navy Ships |
 | | Nimitz, the lead ship of the class, is also the first of its class to undergo this major life-cycle milestone. |
 | | The Navy elected to overhaul the Nimitz without adding cooperative engagement, integrated ship self defense, the advanced combat direction system, the rolling airframe missile, the SPQ 9 navigation radar, a common high-band data link, the battlegroup passive horizon extension system, an outboard weapons elevator, conversion of nuclear magazines, emergency ordnance handling, and improved propellers. |
 | | Other Nimitz-class carriers will follow so that a carrier will be in a shipyard undergoing a nuclear refueling overhaul for about the next 30 years, with the exception of about 4 years during this period. |
