After more research I've come to the conclusion that in 2016 France was only offering a more challenging variation of the Brazilian solution [1].
This means, for Australia, France was mainly offering the Shortfin SSK (at about 3 times the cost of a Scorpene).
France was also vaguely offering a Barracuda SSN hull which might be see service after 2050 IF Australia, like Brazil, developed the reactor. [2]
In 2021, after the AUKUS announcement [3] France MAY have attempted to play catchup by PERHAPS offering a Barracuda/Suffren SSN (reactor and all).
But as at 2022 France's nuclear submarine industry is in less condition to "deliver" an SSN (built in Australia) in under two decades, than the UK or US.
France's limited nuclear submarine building capacity is fully committed with French Navy orders to complete 5 x new SSNs and 4 x not yet fully designed third generation SSBNs.
All French source SSN advice Submarine Matters has been receiving in 2021-2022 has been vague, unverified and often suffers from poor translation. Without reliable sources, particularly French Government documents or French Government statements it is all "spin".
I'd be grateful if such Documents or Statements could come in .html format, which permits translation. Regards Pete.
