3 metre Minimum Torpedo Depth another realism mod

[Der Teddy Bar]

During WWII the minimum practical torpedo depth was 3 metres. Deeper in bad weather.

There are always some saying that you do not have to do it, but, well, we could say that about a lot of realism aspects that we demand :up:

I Look at this like DiD...

I quote from Doenitz's BDU entry in Oct 1939

The problem of torpedo failures is unfortunately still far from being solved. U 25 reports 4 failures at one stopped ship, shots at short range. The Torpedo Inspectorate's instructions were observed. There is therefore no longer any doubt that the Torpedo Inspectorate themselves do not understand the matter. At present torpedoes cannot be fired with non-contact firing units, as this has led to premature detonation. Their depth setting has to be 2 meters less than the draught of their target. There depth may not be less than 3 meters, as otherwise there may be surface runners in which especially the engines of the G7a may be damaged. Exact instructions are given for setting the safety range and these are observed. Nevertheless at least 30% of the torpedoes are duds. They either do not detonate at all or they detonate in the wrong place. There does not seem to be any sense in issuing new instructions to the boats as they never lead to the desired results. The Commanding Officers must be losing confidence in the...

So to have a minimum depth of 3 metres open the dials.cfg and change the DialVal= under [Dial0] from 30,330 to 55,330 & RealVal= from 0,25 to 3,25.

[Dial0]
Name=Torp_Depth
Type=16; DIAL_TORP_DEPTH
Cmd=Set_torpedo_depth
Dial=0x3B0600FF
CrtVal=0x3B060001
NewVal=0x0
DialVal=55,330 ;; 30,330;; <== Change this line
RealVal=3,25 ;;0,25; meters <== Change this line
Circular=Yes
CmdOnDrag=Yes

This will also have your torpedo default to this depth.

NYGM always aiming for realism!

Thanks for that little tid bit. I was getting tired of setting the torpedoes to 3M constantly.

Edit 1:

I did as you said, but when I went to test it, my torpedos had been set to 6M! Here is the line from my dials.cfg:

DialVal=55,330

Edit 2:

To get 3M depth setting I had to make it 15,330. I'm not sure if 55 was a typo or if it is mod specific.

I Like that also,

It does help me to try and stop torpedoes from triggering premature effects.

Nice work :up:

Great!

Myself, I never set my torpedoes to run shallower than the default 4m anyway (actually, I rarely fire anything other than impact torpedoes @ 4m), but that's a good addition anyway :)

Teddy Bar, you can only do this if this setting will only effect the G7a Torpedo.

Reason: In 1940, tests with the G7e Torpedo (AZ-pistol) resulted that the torpedo is running always 2m deeper than set. The Kaleuns had to subtract 2m from normal depth setting. So if you have a dial with minimum of 3m, you are limited to hits in 5m depth with G7e-AZ - in realistic terms.

So as opposed to G7a surface runners, we have G7e deep runners.
I think you should not modify the dial, unless you can make sure that it adapts to different torpedo types and their specific problems.

All I have to say is be careful as torpedoes at 4m bounce right off the rounded bottom hulls of the small tanker and the Liberty Ship.

OK, my bad on this one... You need to also change the line RealVal=

[Dial0]
Name=Torp_Depth
Type=16; DIAL_TORP_DEPTH
Cmd=Set_torpedo_depth
Dial=0x3B0600FF
CrtVal=0x3B060001
NewVal=0x0
DialVal=55,330 ;; 30,330;; <== Change this line
RealVal=3,25 ;;0,25; meters <== Change this line
Circular=Yes
CmdOnDrag=Yes

With this your torpedoes will by default be at 3 metres and it will be a correct depth setting as it was taking the 3metres to be 0 depth and working as such....

As the SHIII torpedoes have no depth keeping issues then the above is nice history only.
