Classic government F-ing job.
3 of the Saturn V’s did not go to space. Not a single engine left? No plans? No microfilm? How many Billions did we spend ( when Billion was A LOT of money) on those?
Read the article linked at post #12. You’ll see one or two related articles linked at that site, regarding the F-1b engine. Interesting stuff.
We kept the plans and the spare engines. What we didn’t keep is the knowledge base of *why* they were built that way - the rationale for the design decisions as it were - and the skills to build an exact copy. We also didn’t keep the jigs, fixtures and machinery needed to make more - as the article points out, even the test stands were repurposed beyond the ability to reuse.
Without those, what you have is a bunch of useless paper. And that’s more or less what we had.
