I have sailed as a british Ubersub in the queens sailpast and led their
squadron. I have sunk a few battleships otherwise but mostly
using torpedos as priority giant killers normally in my heart I just
sink battleships to get the destroyers pissed off and looking.
then its a fair fight at battle depth.
I still Uber on the surface but I do use it as a sub now and then for missions
particlarly with the new version.(soon to be released)
