Refurbed, this old beauty has years of life in her.
The hull might but the propulsion plant has seen it's life. To do a refurb on the 8 boilers that would make it safe again would just about mean replacing them. That would mean taking her apart almost down to the keel {bottom}. When the keel was laid the boilers were among the first things to be installed and the ship built around it.
This is a 1200 PSI super heated steam system. Very dangerous and can be very deadly. Then there's the turbines themselves, Hydraulics including elevators, shaft and shaft alleys, generators, switchboards, etc. The Auxiliaries such as the chill water A/C plants and the miles of associated piping would also have to be replaced. In short it would be quicker and cheaper to build a new conventional carrier using either the Kitty Hawk or JFK blueprints.
The carriers at about 25 years service under go a Ship Life Extension Program or S.L.E.P. which is a comprehensive overhaul that takes almost 5 years. Every carrier but AMERICA CV-66 underwent this to give the 45-50 year design life. America was decommissioned instead as a money saving measure. They then ran her several years beyond what was safe. The result was a pier side boiler room explosion upon return from her 1993-94 MED Cruise. She was towed Cold Iron up to NNSY in Portsmouth, given a Band-Aid repair and sent out for yet another deployment and then taken out of service.
In past history we've sold ships to other nations. Several things to consider. They usually were Diesel engine propulsion, did not have the classified material a CV does {Classified below second deck} and those countries could safely maintain and operate the ships. A carrier takes a well trained and well experienced crew to keep it running safe. As for CONNIE being still classified? America was a Kitty Hawk Class same as Connie. She was sank in 15,000 plus feet of water to protect that information.
They don’t need it.
If they want a carrier they will design and build it
