I'm having fun with a full sternload of Mark 27s (did not do wonders for my renown balance, but what's it for?). I have sunk three DDs with them.
Finally I have come up with a stragegy that seems to work with them. I had very spotty luck with down the throat shots. And when I missed the torp was off into never-never land never to be seen again. So I thought again.
My last two shots have been two hits and here's how*. I don't bother shooting at mr DD as he charges the first time. It's chicken out and go deep time. After several runs him and his escort buddies are kind of all around you. At that point set up for a shot at bearing 180 out of the stern tube and brace for fun. Put all the DDs roughly behind you and ascend to 99' or less to shoot. Shoot and go back down. You have plenty of time. Now turn toward your torpedo and put on a high speed run to make some noise. This will turn the torpedo back toward you to pass overhead.
Wait for fun! Since the torpedo is slow, you can turn it at will with a burst of ahead emergency. This way you can keep the torpedo active in your area for about seven minutes! Believe me, the DDs need to occupy the same real estate as the torpedo to get you and they don't know it's there. Don't tell them, they'll find out on their own.
