Better now than in combat!

I agree.
While the definition of a boat/ship is "a hole in the water you pour money into", the whole class of vessels seems inordinately beset with problems that might prove terminal in combat. Loss of power/propulsion not the least of these.
Lately, that seems to be the hallmark of American Naval construction, and I wonder if the problems are design, execution of that design, or a combination of those.
At some point, especially if we get in a conflict with a top tier adversary, that crap has to be cleaned up, pronto.
