I definitely have to grab this one!
It seems more difficult to find good reads on French side of things, and it's really frustrating.
I'd say look at this one:
https://www.amazon.fr/REDOUTABLE-LHI.../dp/2357430974
I don't have the book, I saw it at a bookshop years ago and didn't pull the trigger on it back then, which I regret now. The narrative sounds, well, questionable (the Redoutable picks a survivor during her last cruise, the survivor is then used as a stand-in for the reader, he talks with the crewmembers who give him a guided tour) but it really is detailed and goes quite deep in details of both the Redoutable herself and submarine tech in general. The illustrations are really goog, too.
