The Freedom class has been having a lot of problems with it's engines, too.

It might have something to do with new low-observable intakes and coolant systems. Otherwise, I'm not sure what would be so different than the power plants of older ships.

I was being sarcastic. Zumwalt power/propusion system is bespoke,

Most ships power plants are bespoke, so are the drive shafts, which is more of a problem, looking at the post from AP below. Leaks like this often lead to the need to lift the ship out of the water. However, it is not unusual that a new ship has issues that require rework after the first shake-down trip.

Associated Press wrote:USNI News, a publication of the U.S. Naval Institute, reported on its website that the ship was in the canal when it lost propulsion. Crew also saw water intrusion in bearings that connect electrical motors to drive shafts, the website reported.

I will have to profess ignorance of what "bespoke" means in this context. Made to order? I assumed that the plumbing was special order, but I thought the actual engine was essentially of the shelf.
Of course, none of the problems I have heard about so far have actually originated in the engine itself.

I should have clarified. "Bespoke" in the context of the Zumwalt kit being completely different from what is installed on legacy ships. The experience gained with the USS Makin Island did provide input into the DDG-1000 design.
