Couple of dumb questions...

Thanks Sniper297, that's what I was looking for. It looks awefull in text format but if it works that seems to be a working solution.

I had thought that the leading angles would be a bit skewed from that of the actual TDC. How did you come to those solutions? Was it just trial and error or did you mathematically come up with the firing angles?

I need somewhat the same but for 29 knot electric torpedoes. And for different speed convoys.

Here is the thinking that I've been doing... Since an electric can only go 4000 yards, I need every attack attempt to be within the 4000 yard range. So if I were to have a 2 x 2 convoy, 750 yard spacing, at 11 knots, I'd want to be about 1500 yards from the closest merchant's track. Depending on where the escorts are going to be, this may or may not be possible. I would try to hit the far merchant in the front line first, then the closest one in the second line, then finally the closest in the first line. Shooting 2 torpedoes each.

So, I'd preselect my target bearing to 20.5 degrees and wait for the first shot to cross that line. Preferably one ahead of the bridge and one aft. As soon as the torpedoes are away, set TDC to new bearing for second shot. When this happens the AOB stays the same but the path is incorrect. But need an adjustment to compensate. This I still need to figure out. Once the torpedoes are fired on the second ship, then go back to the first bearing and reset the TDC back to 20.5 degrees for firing on the last and closest ship. Only problem is, time from first firing to third firing is only 46 seconds. And I'd need that adjusted angle to make the timing correct for the shooting the second ship.
