Crush depth

[Subwolf]

What is the true crush depth of the different SH3 U-boat types, or in other words...at which depth did you die?

According to the manuals the max depth of a VII is 225m, but I thought it could dive even deeper.

I went down to 500 meters once, but that was a glitch in the game, so it doesnt count....

[bookworm_020]

I get to around 150 meters and my hull decides that it doesn't want to take the strain anymore. Can't figure out why! Maybe it doesn't like the way Bernard put it together when it was under construction!!

It is hard to know exactly what was the crush depth of those subs, at first it was a war secret, and after the war not too much info about that.

But at siome web pages is presented information about situations where they dive too deep and return.

Even with the design data, it is realative, because the hull suffer stress, and the crush depth sure will vary with the hull life time.

SH3 Dev. Team confused the maximun operative depth with the crush depth.

The maximun oparative depth was intended to ensure a good hull life time, but the maximun opartive depth not means the hull must crush at that depth.

In example if a hull with maximun oparative depth of 225m is used so never go down that value, in example it will have 2000 dives life time prior to have stress problems, intead if it dive frecuently to 300m, its life time may be reduced in example from 2000 dives down to 500 dives. (this values are only suposed examples, not real values)

In some places i remember to read, they ensure the crush depth was near to double of the max operative depth.

In example here... look at "The Boats" and then look at VII C/42 :

I remember some times people mentioning historytells about determined sub which dives too much beyond the maximun operative depth and back home.

May be some body can remember any one.

This was a long discusion on SH2 and at early times in SH3, you can take the crush depths stored as data into the SH3 Crush Depth Mod from TimeTraveller as a good value.

Hope this can help you...

last night on a type VIIC 327 meters on GW1.1a after attacking a task force, the problem was getting it to surface again, flooded was fixed and it begin to go up again but it was too slow, the problem was that the hull integrity started to deteriorate even when i was going up again and so despite my brave damage control team at 259 meters it gave up on me . this was the deepest i have ever went without using the crash depth mod ( I WAS VERY SURPRISED )

Don't think any kaleun ever came back to report the true depth

"The dockyard certifies us to 90 meters, but we can go deeper."

with hull fixes I still never go below 140 meters 95% of the time. The trick is getting below about 98 and then changing your depth at just the right moment as they dump DCs on you - going about 20 lower each time or even sometimes I come back to 70 if the angles are all correct.

I have actually quit playing SH3 for the moment because in tests I found I could too easily go through a screen of 6 DDs set to expert - that is when I use my decoys correctly. I take damage but nothing serious.

The truth is once you get the AI of the DDs completely down in your mind - you start crying because you don't have multiplay with humans in DDs!

IIA = 152
IID = 157
VIIB = 225
VIIC = 247
VIIC/41 = 247
VIIC/42 = 247
IXB = 216
IXC = 232
IXC/40 = 232
IXD2 = 235
XXI = 285

:hmm:
I thought that the VIIC/42 was able to dive deeper, and I didn't know that the type VII could dive deeper than the IX.

In my case, i dive as much as 45m 95% of the time, i change my crash dive to 45m, from stock 70m, due to the crash dive bug, to complete the crash dive in short time.

Only in rare situations i go deepest than 45 meters.

You are welcome !

I think so those are Maximun Operative Depths not Crush Depths. Between the max operative depth and the crush depth never can be a 5% of tolerance only.

Some places in example the link i put above mentioned a 100% of tolerance between max operative depth and crush depth.

Looks like there is a workaround for the dreaded crash dive bug. You just have to make the weather calmer when you reload. See this thread: http://www.subsim.com/radioroom/showthread.php?t=101482
