If your sub can move faster than the ship when you're submerged, it's not that hard to get a hit firing blind.

What you do is approach him at periscope depth on a parallel course. Once you can see him you can lock onto him and get your weapon officer to identify the ship and give you a firing solution.
This will give you the target's speed and you'll be able to see his position on the map. Make a mark on the map.

Next go to flank speed and get in front of him while running mostly parallel to him. When you're almost out of range, make a second mark on the map and draw out his course line. At this point you should have a very accurate course line and since you're running submerged he probably hasn't seen you and won't change course. Make sure to tell your hydrophone operator to track that target.

Move out in front of the target and take up a position 350 to 400m off of his course line and come to a stop. Ideally your sub should be perpendicular to his course line, but if it's not, use the protractor tool to figure out what his bearing will be when his AOB is 90'. (you want a right angle between his course and your sub's position)

Go to the targeting computer and enter his AOB at 90', his speed, and your distance from his course line.
(don't forget that the ruler rounds to the NEAREST 100m. At 351m it changes from reading .3km to .4km)

Point your scope at the bearing where the target will be when it's at AOB 90'. If your sub is pointing straight at his course line that would be 0'.

Open the tube doors and listen while the sonar man calls out the bearing to target. When it's the same as your periscope bearing fire the torpedo.

Since you know his speed, AOB, distance, and bearing from all your setup, you should get a hit even though you can't see him or lock him.

Also, it's kind of a cheat, but if you keep hitting "L" when your scope is pointed at a ship you can get a lock for a second even if he's out of visual range before you lose it again. You could fire right after getting the lock to increase your chance of a hit.
