2) alternatively, SpaceX could fork the design as you pointed out, and lock down a version/model of the F9 for the USG military launches, while allowing some innovation on the other model. ....
Likely the only way someone can duplicate what SpaceX is doing is to essentially start from scratch, which means building a new Falcon 9 class rocket - and everyone else in the world has already locked in their design choices for their current generation of launchers, so until someone decides to build a brand new rocket we are unlikely to see someone else try to duplicate what SpaceX has done.My $0.02
On this point, does anyone know if the certification process is designed as a co-operative effort -- maybe like the NASA-SpaceX relationship where (I believe) that SpaceX is gaining from NASA's expertise while the SpaceX systems are being 'vetted' -- or as an adversarial or neutral process? Co-operative would certainly open possibilities for improved systems and launch flow, while adversarial/neutral would be opportunity lost.
Two points: as I understand it, Atlas V and Delta IV have not been frozen in time since the first EELV launch, they have been incrementally improved..
Wrong. The government has the monopsopy on the military market. So it is a state regulated market. Noone can enter the market unless the comply with the (wise or unwise, good or bad, ...) regulatory process to compete in that market. That was my point.And those regulations will tend to both slow innovation, and increase cost to anyone who wants to sell into that market.
I am fully aware and in agreement with many of the concerns posted, however, the AF is not a typical USG, civil service bureaucracy. Many of these people have state-of-the-art training and are wickedly smart. We may be very surprised how the introduction of SpaceX into this process will begin to alter both themselves and the AF into an amazing partnership where each learns from the other. It's going to take some time for this to happen.
Wrong, it is not semantics. Nobody is forcing SX. SX does not have to be certified and it doesn't have to fly USAF missions.

If it looks like a duck and quacks like a duck....
Yes, the process has a tendancy to freeze vehicle configuration if your only market was the government. But SpaceX has other non-government customers that new configurations can fly and be used to then certify them to the governemnt. Eventually the certification process will be just a paper exercise without meaning as vehicle inovation increases basic reliabilty way beyond that being sought by the AF.
I was wondering at this strategy. Incremental changes on every commercial launch (within reason) then once a bunch of changes have been proved out do a "block upgrade" to the DoD version, all at once.
Just wanted to point out that CNC has been around for decades (1st generation CNC used paper tape), so advocating that it is "modern" is a misnomer. Even friction-stir welding (FSW) is no longer "new", just yet another manufacturing technique that is now proven and well understood.

I think FSW will be the SoA approach for future LV's.
Who says the commercial customers (and their insurers) like being paying crash test dummies on every flight? Why wouldn't they opt for certified, stable and proven version too?

I am sure that NASA reviews helped them a great deal to build a launcher with zero primary mission failures after losing 3 out of 4 F1s.
