Lots of acoustic torpedoes, and once you leave the pen and are in open waters, it's a must to run at snorkel depth, until you're out beyond the range of land based planes, then you can surface, since I don't run into too many planes from the CVA's. Also, check your external view at snorkel depth so it's not sticking out of the water too far., Then make a note of where to set your depth manually. If you keep the snorkel head just above the surface, you can usually slip past the air patrols. I know the external view is bogus, but it lets me set the finer depth adjustments until I know where it needs to be for the most efficient depth setting. Stormy conditions, I just run on batteries until it's a must to surface a recharge them.

The acoustic torpedoes will either sink or disable the DD's, and DE's, but you must work fast, and once you launch those eels, you must take her very deep, as the DD's are very fast, but will slow when they are within 2500 meters or so, and the eels catch them. Took out 3 DD's from a HK group, and the rest scattered firing hedgehogs everywhere, but I was already gone from the vacinity, by 3000 meters, and escaped their revenge.
