The book Scorpion down, on page 78 they went into pretty deep discussions about the abilites of the ship of the Skipjack class SSN. Apparently at flank it was able to hit 35knots and could dive all the way to 1300 feet. I am not sure if that was test depth or crush of course because they wouldn't tell you that
But I have played around with this mod and its really fun. I havn't even edited or played around with the mods myself but is there a way I could set these statistics in the mod to reflect these numbers?
