I don’t think all or nothing is the only option. Reducing the signature can have massive benefits.
There was a great book called “Skunkworks” by Ben Rich, who took over for the fabled Clarence “Kelly” Johnson, he drove the development of the F-117 Nighthawk.
In the book, he discussed how the benefits of stealth could be applied equally to either an aircraft or an aircraft carrier, which blew my mind, and the benefit wasn’t dependent on size.
If you have a far smaller RCS, then a missile depending on radar can be more easily defeated by countermeasures.
As for the power, it is developed by special marine tubines that generate a huge amount of power (78-megawatt power station supplying electricity to an advanced integrated power system (IPS)) and the power is both used to drive the vessel through the water and to power weapons systems demanding power, such as a rail gun. The electrical infrastructure is massively changed from current systems on vessels, but I don’t know the specs on it. I saw that, for alternating current, instead of using the standard three phase power motors in usual AC systems, this special system uses 15 phase motors. I only dimly grasp that, but...it sounds like it has something to do with speeding up the conversion of power to energy as needed for various tasks. (Maybe someone else on this thread understands this better)
I do know the ships ended up being built as technology test beds, which certainly didn’t make them cost effective to build.
