They are good at distracting enemy DD, CL, CLT and CVL because they will all go after subs when it is present. (including pvp)

before level 10, armed her with midget sub you use on torpedo cruisers. This gives them pre-empt torpedo attack.

after level 10, remove the midget sub (sub gains auto pre-empt attack at lv10 so you dont need to use it anymore) start use her as flagship and fill the rest with your usual lineup. This way she will never sink, just keep lvling till she gets red damage then repair as required. Best equipping her with turbine if you have any.

once she hits around lvl 30-40 you can send her off in 2-3 farming runs (hopefully u have more subs by now). Solo sub is hard because it is sometime hard to get a win (losing too much drops your win ratio that *may* prevent you from joining certain event) and you tend to get damaged quite often.
