Building hundreds of aircraft carriers a year is an issue of scale, so of money and allocation of resources (assuming we have the manpower). But what I mentioned is more profoundly that we simply don't know how to even build one. It's knowledge and technology which are lacking.

Typical these things fall into one, two, many. Can you build one, two, many? These are very different propositions.

One means you know understand how to do it, mostly.

Two means you can repeat it, so you do understand it, it wasn't a fluke.

Many is scaling the process.

Scaling is a technology of its own (and it's often the hardest part).
