First of all, the SS5's will be better than the SS4's. That is a given.

The SS4's are ALREADY overpowered as it is.

Are you saying that submarines should be able to beat both submarines and carriers, while being at a lower level?

Furthermore, Subs can avoid ALL HH and DC; It takes just over 2 seconds to crit dive, while the HH detonation timer is just over 3 seconds.

Furthermore, bulge does very little against submarine torps. It was tested. The damage of the torps is just way too high. The fact that an IJN SS4 cripple shots a QV with belt just crazy.

Furthermore, relying on escorts that randomly cross allies, fictory out of the battle line, have hugely poor aim and are not allowed in all game modes is just wrong.

some coments on your points LJ

1 ss5 shut be better then the 4 its the next ship in line( if OP then nerve if not leve it alone)
u have ss u say anny above lvl 100 thats where the crew won't fit and u have to ghost to play

2 not all ss4 are OP only the ijn(8torp) and km (troxy) the rest are/have bad torps bad boats
the ijn is the bb killer and the km the anti asw/ss

3 the ss5 shud be at lvl 95/100.preferebly at 100+

4 all ss can crit dive dc even when unther speed and OH
but hh when unther speed it takes time to slow the boat down
and ritcharts test was on a parkt ss make a test wher the ss is onther way and on OH
it will take more time to crit then when its parkt

5 thats wy its a bb killer and if its the test i think it is was that test wason a QV that was
parkt and at the max range of the ss so even the duds will explode at end run
try one where the QV moves it will be alot harder to 1 shot then

6 escorts fail on anny boat exept for cv's
but the game needs to be about teamplay
insted all we have is players rushing out in dd'/ff and getting shot by bb's
befor the firts 2 min of the game are done
ss that have to figth ss and while doing so get hh's on there head from the team ending
up getting damaged/killd (let ss vs ss fight and if yours dies then hh)
and then there are cv's who wont scout and only divebomb/ torpbomb
and not even letting the plains stay over the ememy line if there are done bombing
to provide site those plains usely get shot down on the return trip so u lose them enny way

and than there is 1 ss that got thru and is the sole scout for your team
but he won't get anny kills becos the bb can see and shoot all its targets

this is a skill lvl game and some one being a lvl 120 hall of famer
dos not make thim anny more skill full than anny noob in a blitz
work together and stand a bether then 50% chance of winning
be the lone wolf and die fast its your choice

new tier SS5 has been long due, it should be released when SDE is ready to do so.
anyway, by the look of the specs, they are more PSS than anything else.

SS should be treated as a full line, SS1 to SS6, and balanced accordingly (some serious work involved).
one good thing would be to lift the whole line upwards, SS1 starting later, being just at the limit to play a couple of blitzkrieg. the current SS4, renamed SS5, could be around 103 (BB line) or 97 (CV line), provided there would still be a PSS (the new SS5 ?) and an SS6 to come.
i am not the first nor the only one to offer this change as part of the solution.
the pseudo argument of an "OP lvl 74 ship" would slowly fade away.

sub drivers are already at a disadvantage with the torps XP nerf, and the current displacements which force them to skim their crews.
they want to be part of the game with their ships.
they would probably happily engage in attacks against heavily protected convoys, if they were given a chance. most of them love trying to evade DCs. they would probably like more challenges, and more rewards.

on a side note, it would be adviseable to balance the testers' team as well, opening it to some of the most serious and moderate sub players, and controlling some of the sub haters.

just suggestions,
cheers
