You can certainly buy high-volume forging equipment.

You can certainly buy them from China :) They WILL sell them to you.

Or, rather, from one of their US dealers

Raytheon knows all about that. They admit they are dependent on Chinese subcontractors.

I can't find it now, but Schuler's largest stock press could not accommodate 800mm+ stroke
That's why, for example, an automobile crankshaft forging press could not be adapted - crankshafts are forged flat
So this ends up being a custom job, which is part of the delay. (and an obvious argument that you mothball these things in peacetime, not sell them for scrap)
