So... if max depth of 688(i) is classiffied - how do you know that is about 1600-1700ft ? Hmmm... Inormations which had Clancy (to write that book) are more reliability than someone's speculates.
If 688(i) has lower thickness of hull than older US subs (like Permit or Sturgeon class) - it can't dive so deep like them. It's logic for me
So 688(i) can't dive so deep as Seawolf or Akula class subs.
It is important becasue every mod which come out from subsim is something like dogma for enyone who play this game. For me too
