I am dubious of the radar claim. I would think you would want an all or nothing signature.
Not explained in the article is who they generate that electric power. It has to come from somewhere. But the ships are actually position to be able to provide temporary power in coastal locations.

They each come with two 155mm guns - with non-procurable ammo. Not optimal in a shooting war.
The way to test the radar claim is to send one into Iranian or Chinese waters.
if they’re stealth, then park em any where you want!
It’s no wonder there are problems after naming them after the most disastrous Chief of Naval Operations in Navy history.
A recent article discussed the successful re-fueling at sea by an oiler. I believe 47,000 gallons of diesel ship fuel were delivered to the Zumwalt. That, of course, is converted to electricity which drives the Integrated Electric Propulsion system. Theoretically, the enormous capacity to generate electricity is useful if you a railgun as armament.
Well, if you want a semi-useful comment...
The ships are turbo electric. This was tried back in the 20’s with Lexington, Saratoga, and the Tennessee and Colorado class battleships. It worked well and had some advantages, including the ability to provide backup power to the town.
(Other advantages included the ability to control the power to each propeller shaft independently, etc.)
As to the radar claim, if it’s foggy at night, and you see a blip on your radar about the size of a fishing trawler, you’re much less likely to shoot at it, right? (vs seeing a 600+ foot return)
If they’d built all 24 of them, no doubt they’d be the pride of the fleet. As it is, it doesn’t matter how good they are, they’re white elephants.
If they’re actually good, they’re too valuable to waste on a potentially dangerous combat mission.
If they’re terrible, well, then they were just a total waste.
As it is, what they really are is just a testbed for spiffy cool new boat technologies. If they work, they’ll make their way into other ships. If not, well, they probably won’t do that again.
(Until enough time has passed that they forget that putting the tripod mast behind the funnel is a bad idea.)
It seems to me, with the technology and stealth, they could operate in a carrier fleet as first contact perimeter detection and defense.

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.
As regards the “production of power” electrical power and engine power for the turbines.... welllll, the Great Green Fleet obmaumao’s and libs politically correct environmentally, and extremely expensive “Green” fuel sourcing (bio-fuels super “high tech”— and proven to foul things up as well. Bio diesel, etc. all tested on the farm first, and found lacking in extreme).
There is this— a ship that cannot run with the Fleet, and major number of engineering casualties, embarrassingly so:
As clear case has made— theory vs. reality. Great the ship is stealthy, but if it can’t run effectively, and not needing “exchangeables” to basically make power for the turbines from the “green” fuel on down to the “heat exchangers”(a technology that should be well understood, except for this design).
So, it’s a very expensive test bed (rail gun is already tested, and ready to go- an exciting stand off weapon reducing the need for propellants on board) and the Navy has decided the Mansour will be the last, and requesting 20 plus more NEW Arleigh Burke class tweaked to the max with all the new goodies, and turbine powered.
Is this Bath, Maine?
L.P. I think you have some exposure to his subject. Any thoughts?
