Make a radius circle on the target to measure the exact distance in nautical miles.

The RTE must be set lower than that distance.

RTE means the range at which the missile drops its torpedo payload. The torpedo would still travel some distance after being dropped in mid air. You need to take that distance into account by guess approximation and experience.

If you want to launch 2 missile torpedoes to sandwich between the target both RTE's must be set lower than the range or at max equal to the distance. You need to get those torpedoes to hit the water(not just dropped) as close as possible to the target since these torpedoes are only going to go circle and their endurance due to their small size is not great at all.

The thing I loath is that these have small warhead and in DW 30% damage is just a superficial number while in RL even a 30% hull and shock damage is probably going to incapacitate a submarine rendering it out of combat or severely crippling it effectively making it a neutralized target.

There's no way a starfish or the like hit submarine in RL going to simply say 30% damage to our submarine, flood tube 1 and 2 set bearing 60 degree RTE 8000 yards, active! Open torpedo tubes, launch tube 1, launch tube 2! No way!

In RL they are going to have destroyed compartments, severe flooding, fire, substantial casualties and crew shock, equipment and electronic failure, etc.

Double hull may sustain less critical damage but they aren't going to operate like usual at all still.
