Navy Mulling Extending Service Lives of Nimitz-class Carriers

Quote
The Navy is assessing whether to delay decommissioning timelines for the first few ships in the Nimitz-class, Program Executive Officer for Carriers Rear Adm. James Downey said at a symposium hosted by the American Society for Naval Engineers.

Specifically, the Navy is evaluating the timeline for USS Nimitz (CVN-68), with an eye toward coming to a conclusion about the first-in-class ship within the next one to two years, he said.

“You have 40 more years of Nimitz life, but Nimitz herself is coming up to potentially an end-of-life-cycle at the end of this [future years defense program]. But she has capability beyond that point,” Downey said. “So we’re looking at where that capability sits from a timeframe perspective. It’s — generally the math takes you to the 52 or 55 years, so we have that issue that we’re going through.”

Downey said the Navy is analyzing its upcoming refueling and complex overhauls (RCOH) and docking availabilities as it assesses whether or not to delay Nimitz’s decommissioning.

WW2-vintage Essex Class CVs were made obsolescent by the adoption of larger planes such as (IIRC) the F-4 Phantom II. I'm not aware of any similar factor that would render early Nimitz Class CVNs obsolescent or obsolete. It's more of a (cost-to-overhaul + expected useful life) vs. (cost of a new-build + added capabilities) issue.
If, as anti-Covid-vaxxers claim, https://www.poynter.org/fact-checking/2021/robert-f-kennedy-jr-said-the-covid-19-vaccine-is-the-deadliest-vaccine-ever-made-thats-not-true/ , https://gospelnewsnetwork.org/2021/11/23/covid-shots-are-the-deadliest-vaccines-in-medical-history/ , The Vaccine is deadly, where in the US have Pfizer and Moderna hidden the millions of bodies of those who died of "vaccine injury"? Is reality a Big Pharma Shill?

Millions now living should have died. Anti-Covid-Vaxxer ghouls hardest hit.

I think there are ten of these carriers.  They carry plenty of aircraft.   All are nuclear powered for long deployments.  They can do 30+ knots.  Why discard ships that can handle any job they're needed for?  Doesn't make sense.

I've heard hulls are only good for so many years, regardless of the number of overhauls.

How long that is, who knows. The Iowas could probably still handle regular service.
