Radio Robert has the best 30K foot overview of the program. There are so many moving pieces to this program. Keep in mind, even a CDR is only the
first true launch phase on making significant inroads to pre-production. Given the fact that this program has massive compartmentalization and a
number of major subcontractors (engine, avionics, structures, fuel and hydraulic systems) it would be naive to think any significant work has been
done prior to CDR. Like any engineering, manufacturability is often at odds with intended wishes. There will be drawing revisions across the board top
to bottom. As long as Aerospace programs have existed there will be teething pains. Some more acute then others.
I remember Martin Marietta (at the time) trying to pitch to the USAF that the Centaur upper stage to the Titan IV ELV would be 90% the same as the
We ended up releasing over 95% new drawings on that program. No matter how many times the powers that be it the US Government or contractor say a
project is a “slight mod” to an existing platform, that statement is a bald faced lie.
