It has been my experience with this torpedo that you must use it like any other torpedo. except for the following...
1. It is most reliable against warships - particularly escorts.
2. It is most reliable when used against escorts with a 4 meter depth setting and magnetic trigger
3. you will still have to plot a solution on the target
4. they do not start homing until traveling several hundred meters ... IIRC it is over 500 meters distance before they start to home in on anything... or it might be that they do not start homing until they have passed the range setting in your solution - i cant recall.
things to watch out for... if they are seeking a destroyer and he turns toward you to DC you - you are then at risk of getting hit by your own torpedo as it chases him!
also it will seek to the closest / loudest sound when homing so if you were aiming for a merchant and a desttoyer speeds by it might start chasing him instead of the target you were wanting to hit.
I have used them with over a 95% success rate - and they WILL home in on something using small "S-turns" to chase the target... good way to ensure a hit on an unsuspecting escort.
