Submarines - How to use them, How to abuse them.

[Ironshibby]

Hi Guys, 

I've left the game for a few years and returned this week, got back into the German DD line that I like to play and at ship level V discovered submarines with homing torpedos in the game. 

Ok, this isn't remotely historical but it's a game whatever let's move on. (There were subs around in WW1 but they were crappy, and by WWII they were more of a threat so they belong in Tier8 games and above IMO).

IS THERE A GOOD STRATEGY GUIDE FOR THESE ANYWHERE? 

Part a) would be 'how to use' and part b) 'How to sink them'.

I've read that some people are using them to sink CV's which is actually a nice rebalance against these horrible craft that make my DD's incredibly difficult to use effectively. 

I'll plan to sink them if there is a good method available, this time I was in a tier 5 destroyer with sonar and still couldn't locate the nearby sub; this is just plain wierd. It's Hydro but can't detect a submarine? 

I fired guns and torps at it, both of which will work IRL but to no effect.

Then I dropped some charges on it and it still didn't sink. So, ah, what the hell am I supposed to do?

drop more depth charges and circle him till you can shoot/torpedo him
