I agree with this in entirety there is a whole set of production steps that take it from a skeleton to seaworthy to battle ready. The issue from the American perspective is that those shipwrights, technicians, and other workers do not have a job past the conclusion of their phase. After primary construction is done you just don't need as many welders. If the ship has been wired properly to completion you don't need as many electricians, and so on and so forth. This especially holds true because after acceptance by the military most of the maintenance roles will be taken over by enlisted personnel or contractors separate to the production staff. The problem is it turns into 'if we don't order a new ship we're down 5,000 high wage jobs.' So while Ship A is being polished for deployment the original company has a bunch of staff that they don't have any work for. The next contract that comes in provides money to cover those 5,000 jobs to do that primary construction over again to build Ship B.

I'm also not sure in the comparison between foreign governments and US defense contractors but US defense contractors generally only sell to the military markets (domestic or international) so it's not like their facilities are designed to be able to build ordinary commercial goods side by side with the military spec hardware.
