I think you are sim-interpreting what I was saying (and if you see what I've posted elsewhere in the discussion thread I'm very much in agreement with you).

I was just saying that stealth is a component of ship design for small crafts (i.e. those that would generally stay close to the coast) but that it's not the case for larger ships and even for those smaller ships it's just not the primary purpose for radar optimized hulls.

Close to the coast, non-coastal radar won't be able to detect ships nearly as well as out at sea where they stand out like a sore thumb. And of course coastal radar will still light up any ship so stealth there is of little value on foreign shores.

But really outside of some niche cases for small crafts, radar "stealth" is all about survivability and not the traditional view of stealth.

TLDR I think we are pretty much in agreement.
