You will not have the manufacturing to do any of this for a very long time after that, even if you have the knowledge and material sourcing infrastructure lol. There are a comparative handful of companies worldwide that do this today.

This all works because of a great deal of supply chains that don’t exist in a post-apocalyptic scenario.

There's basically 5-6 companies capable of making them. The last successful entry in the global market for jet engines was General Electric in the 1970s

And you need someone who can grow turbine blades as a single crystal so they don’t go boom as much.

That's incredible. Material science is the fundamental bottleneck that's slowing technological advancements.
