> capability in the US to do large castings and forgings is basically gone
This is true but irrelevant to space flight. We don’t fly big cast or forged parts.
Saturn V contained aluminium cast parts, but nothing we can’t make today [1]. (To my knowledge, no components were built in our WWII-era forges.) Modern carbon composites and aluminium alloys are superior, and we’re in the process of surpassing the Saturn V’s capabilities in SpaceX’s Starship.
