"This won't happen with targets in the same column (behind each other)."

" I have yet to see any solution to shooting a column where the torpedoes hit simultaneously. I haven't come up with an adequate solution either."

Depends on how many there are, what kind and how many fish you have. Real world SOP was to fire 1 MOT, 1 aimed to deliberately miss just ahead, 1 aimed to deliberately miss just behind. Usually wastes two fish, sometimes only one, but guarantees at least one hit with a good chance of two.

I use between 10 and 15 degrees angle-off with Mark 14s at high speed, AOB and target speed set to zero - the "Kentucky windage" method kinda like leading a duck with a shotgun, but a little more precise.

Three ships in column, me 1000 yards off the track at a right angle, wait for the first target to arrive at 5 degrees before the zero gyro angle shot, shift to the third target and note the bearing, move the scope 8 degrees in front of him, hit the stadimeter send bearing to TDC, and fire. High gyro angle and about a 30 to 40 AOB impact, but at close range that's not too big a problem. Shift to second target and note the bearing, shift 10 degrees ahead of that, click send bearing to TDC and shoot - less gyro angle, closer range, more like a 60 to 70 AOB impact. Then shift back to the lead target, repeat same send bearing 12 degrees ahead of him, shoot. If the timing is right you have the first fish going 2000 yards, second 1500, third 1000. At 46 knots the fish goes 1000 yards in 38 seconds, 500 yards in 19 seconds, so count about 15 between each shot and they should all hit around the same time. Why 15 rather than 19, while you're doing all this all three targets are getting closer so the run will be shorter than the actual range - particularly for the furthest target, the range is changing faster than the bearing, as opposed to the closest target which the bearing is changing faster than the range.

In summary it's difficult but not impossible to get three hits on three targets in column within a few seconds of each other, you just have to accept higher gyro angles and less than perfect angle impacts for the further two targets. Obviously the bigger and slower the easier it is.
