I was looking at it just a couple of days ago. In order to do it you'll have to have a small bit of tolerance for imperfect solutions because we won't have time to update the AoB while doing this. It won't matter much in the location of the hits.
First of all, we want to do the stern, MOT, bow shot for two reasons. The first is that we are shooting the longest distance shot first. This makes run times closer together and your hits will be very close together, if not simultaneous. but the second reason is that when you shoot the bow, MOT, stern shot, all three torpedoes proceed in a single path toward the target in line ahead. By turning into the torpedoes, the target can easily evade. Evading one of them is evading all of them!
BUT when you shoot stern, MOT, bow, the torpedoes take the most divergent paths possible. Now they are spread out, not taking the same path. This makes it very difficult to evade all three torpedoes.
So let's do this monster for a target moving left to right! Set up your first shot up the 45º line just like normal. We'll estimate a 10º lead, so we'll point the boat up the 45º line and set our scope 10º left of that to the 350º bearing. Our AoB will be 45-10 or 35º starboard in this case with target traveling from left to right. We've got our speed from radar in our original plot of the target course. Our PK is off.
Now we'll diverge from our normal practice. Set our input TDC on the right so you can immediately send range/bearing because we're going to have to do that twice quickly!
We are waiting for our first shot with scope on the 350 bearing and we'll wait for almost the entire ship to cross the wire and aim our first shot to the stern area! Shot away.
Now aim the scope just ahead of the target and press the send range/bearing button. Wait for the MOT and shoot again.
Then jump just ahead of the target again and press that send range/bearing button. Shoot at the bow. Remember that after you press the send range/bearing button you cannot move the scope until after you shoot!
You're done. Taking the minimum time between shots by setting the TDC ahead of time for quick input of range/bearing has kept the consequences of the slightly inaccurate AoBs for shots two and three bearable. You might miss by five feet or so from the spot you aimed. He's still going to make a satisfying blub, blub, blub!
Let me know how your success goes!
