how can I improve my submarine's torpedo accuracy?

[ohthot1227]

The in game torpedo aiming is so poor that a lot of cases even when I fire with my bow aligned to target to minimize error, a full spread of torpedo would completely miss a enemy vessle steaming casually in a straight line.

Torpedoes travel very slowly (compared to shells), they have gyroscopic turning capability but it is still a good idea to aim the sub well infront of the target, depending on the targets course. ie deflection shooting is good operational practice.
Dont bother shooting if the target is heading at an angle away from you ie a diverging course
Best line up for torpedoes is if the target is heading towards you at an angle to pass infront of you ie a converging course.

And I do all that. aiming bow just ahead of target,
target is aproaching at a angled line so that the torpedoes would be almost perpendicular to the target's course at impact,
range is rather close to under 2 kms.
almost the ideal condition for a sub attack

oh and the target is a large battleship heading in a straight line

it's almost a aiming practice kind of condition and...somehow 6 torpedoes in a 8degree spread would completely miss that target to the rear...

Did the target spot your torps and speed up or start turning?
A good spread angle is about 2-0.5deg per 1000yds range, 8 deg is a lot.
Also be aware that it may be a converging course when you fire but then turn into a diverging course when the torps get to the target.

1. No, they didn't know there was a sub in the water till a torp went boom

2. I know 8 degree is a lot. I did that because I was firing from 4 subs at a closely packed concoy of 8 ships. I hoped spraying torps would get lucky hits on transports once they missed the intended military vessle.
I wouldn't be surprized if the torps were so wide that it missed by going pass either side of the target. But the reason I'm so confused is that despite all these idea conditions, despite the angle beaing so wide, they missed completely to the aft of a slow moving battleship.

3. I am aware of that. And as I said, to maximize chance of hit, I time exactly the torps to hit as the converging course would turn into diverging course - thus hitting the targets perpendicular.

What was the subs target solution chance?

like 15%? wouldn't go higher

Only 15%, at 2km?
You should be getting 90+% at that range.
Something is wrong there. Low visibility? Bug?

maybe cuz it was night?

Thats still pretty low unless it was night, overcast and bad weather and probably a bad angle, at 2km. That is what i would expect 15% to be.

Yeah, all that and I assume they didn't identify the target ship? That tends to make a significant difference with subs to get a better idea of what they are shooting at.

Definitely sounds like they were in bad conditions, or didn't give the crew time to build a better solution. You never want to fire early unless you are about to lose the ability to fire at all.

I managed to sink North Carolina and South Dakota and a couple of cruisers and destoyers with my subs (8th and 9th August 1942).

The trick is to have your submarines sail parrallel to the enemy they are attacking not at right angles (this is counterintuitive) fire at the 2nd ship in the formation at max spread. Japanese subs are better than US for this due tot he long lance torpedo.

Just want to point out its a common mistake to think lo g lance torpedoes were used in Japanese submarines.
They were only used on imperial navy surfface vessels.

The 'Type 93' or 'long lance' was only used in surface ships, yes. It was to big to be used on subs.
But a downsized version of it, the 'Type 95' was used in submarines as main weapons.
Needless to say the 'pure oxygen' design which gave the 'Type 93' it's famed abilities was retained.
And so the 'Type 95' had better range, speed, stealth abilities then allied counterparts.
Just like how 'Type 93' was against it's counterparts.

So if by the term 'long lance' you are reffuring to 'the long range and fast and invisible damn ♥♥♥ torps' you can say that ♥♥♥ subs used long lances too.

Just manual aim its quite easy using the torpedo deflection indicator, which is also great for engaging multiple targets. I find it much more reliable than auto aim, especially if your solution is less then like 80-90%
