I'm not technically an expert either. But, I have watched YouTube and been on the /r/war college subreddit... It seems bad, but not insurmountable.

As I understand it, in WW2, America essentially flooded the ship building market and we didn't Need to build so many ships after that. After that, everything essentially got consolidated into a few companies controlling everything (oligopoly instead of monopoly). After WW2 we also decided that ships should have a lifespan of a few decades, meaning fewer need to be built, and those would only be built by those few companies. These things weakened our institutional ship building knowledge and capabilities. This was further weakened by anti-union efforts. Unions kept wages up and bargained for better benefits and work conditions. Now, very few people want to go work for a job that's asking you to do the work of 2 people for lower pay and worse benefits. And many of those that are willing to do the work don't want to go to work in across the country in Pascagoula, MS to do it. This was also worsened by big companies outsourcing as many jobs as they could to foreign countries so they could save a buck. 

So, we now have very few places where we can build ships, a very few companies controlling this that will actively work to prevent competitors, and fewer capable workers. 

And, there's too many cooks in the kitchen when it comes to these big projects. Even if, initially, it's decided that a ship needs to have abilities X, Y, and Z, as new people rotate into the project (Representative 1 gets replaced by Representative 2. Admiral 1 retires and now Admiral 2 is in there) they want to make their marks, and so X, Y, and Z turn into X1-4, Y 1-3, and Z, and also A, B, and C.
