Lau,
If you read the thread you would know that I asked the modders some time ago to add the latest french SSBN. They ended up adding 2 french SNA but not of the latest generation I think.
In any case since the database from the next version RA.1.1 should be open, people can add new models at will, even if the modders won't.
Ok : I went back in the thread just to be sure, and the modders added 2 playable french SNA, the Rubis SSN (France)
and the Améthyste SSN (France).
