Youall (frank and dead) don't have any idea what you are talking about. 15 years ago, one of the hardest parts of my job as parts trouble shooter on the shuttle was to find new manufacturers for parts required on the shuttle, which were no longer manufactured, and for which the original companies were long out of business.

The government small/racial/sexist/disadvantaged business administration directed that many parts be 'bought' from these 'companies', and they didn't exist any more, even then, even for the shuttle. The Saturn 5 would be impossible.

I think the original estimate above for $1 trillion to go back to the moon, is way under estimated.

I work in Logistics and Maintenance, dude. We have to find alternate sources ALL THE TIME. MY POINT is that you will either have to specify parts for a new design or RE-specify for a completed design. It's the same damn thing, except most of the retooled Saturn design is complete.

The only big design hit (and not as big as back in the 1960's) is the re-design of the electronics subsystems, which we would want to upgrade. The next biggest would be the dozen engineers running down the appropriate substitute parts we're talking about. Otherwise, the design of the structure, the jigs, etc. will allow for almost immediate fabrication.

Finding the original manufacturer is irrelevent for all intents and purposes. The production lines have been closed. Rocketdyne and the other Sub's would simply go to their favorite vendors to build parts to the SCD.

They didn't exactly right SCD's for off the shelf stuff, that would have made too much sense.

Building the Saturn 5 wouldn't be impossible, getting through NASA Red Tape might be.
