Proper way of firing a spread

U-5000 · 11-04-07, 08:58 AM

Can you give me any pointers are firing a spread of torpedoes as I seem to have a problem with this. Do you set it to 5 degrees and fire 3-4 torps or do you use less as I have missed with too much ?

I've never been entirely sure of this myelf. But I think you can fire a spread at multiple targets at once. That would make sense as anything greater than 2-3 degrees from within 1000 meters is not hitting your target. I could see the tactical advantages later in the war if you only have one shot at a convoy. the only issue is, you wont beable to make precision 1-shot, 1-kills. im interested in other opinions on this too.

I rarely use 3 or 4 torpedoes at the same time, in fact, never. Most of the time 1 or 2 should do the trick. Just firing 4 torpedoes at once into a convoy seems a little desperate to me, but it could be a tactic.

I never really know what the correct angle is. I suppose with a pen and paper it would be easy enough to figure out. You're trying to compensate for a crappy speed estimate. The way I usually do this is by firing a spread by hand - that is, get the real range (careful stad reading), make your best speed estimate (even the sonar operator's slow/medium/fast is a good coarse start ~6/9/14 kts respectively) and enter these into the TDC. Then, in quick succession, fire one torpedo just behind the bow, one center, and one torpedo just infront of the stern. This way one of them is bound to catch him, unless your speed estimate is _way_ off. More often, two of them will hit because you're off by a knot or two. If your estimate happens to be bang-on, all three hit and your target is destroyed in a fiery cataclysm.

Well i used to fire two salvos with 2 torps each.BUt later when it became nearly imposible for me to get proper solutions for 2 targets i used to fix on the bigest and closest one and fire torps at around 2-3 degrees. Yes often 1-2 torps may miss but it happens also those torps to hit something else.For exaple one such missed torps hit black swan escort witch i havent even saw on the far side of the convoy

As far as I know you should first measure the span of target using the scope and adjust it in salvo angle.(wazoo manual)I've never done this, I just set this angle to 1-2 deg. Setting to 5 or more can give good results when you want to hit many targets but only to make coup de grace later.(convoy attacks)

If I use salvo I'll try to set up the salvo like this.
1 Get all the info as accurate as I can.
2 Just b4 firing get a new bearing and range.
Here I can check the solution. If my range is way off I'll reset it and redo the AoB ( by looking)
3 Measure 1st impact point. (target is passing form left to right I'll get 1st point 340°)
4 Same with 2nd point (target is passing form left to right I'll get 2nd point 330°)

5 result 10°. So I'll shoot with a 10° spread. If you time this correctly all steps from 2 can be done within a few sec.

useally I have time to wait for a 0° gyro shot
