Did the French fail or was there mission creep from when the project started?
Basically zero mission creep AFAIK. But lots of issues out of the gate. The French did not seem particularly interested in talking to local SME and suppliers. There seems to be lots of concern about how sovereign our capability would become if the whole thing was designed, built (with some local assembly of parts) and supported in France. Listing South Australian pizza outlets as "suppliers" to the program did not help the situation.
I imagine from Australia's POV it is a french failure.
Lockmart on the other hand was doing a smashing job, bringing everyone on side, kicking goals on the combat system. Everyone seems very happy with them. That project will likely continue unabated.
Also wondering if the number procured will be anywhere near the same, I can't see Aussie buying 12 SSN's, can you?
Can we crew 12?
SSN's have much larger crews. Astute is about 100, Virginia is about 130. Collins is about 60.
I expect the number of subs to drop to 8. 8 is still a good number and more SSN's than the UK has built. Cutting back numbers puts pressure on the continuous build cycle. Even with 8, naval assets will likely still need more local builds.
Collins is also likely to get a very large extensive life extension/remanufacturing.
But this is a huge change. AUUKUS is a whole new thing, not just in subs, but in aircraft, weapons etc.
Australia has also just penned up a deal with South Korea.
