A quick word about crush depths in TMO 1.5.2 | Forums

[Ducimus_Rapax]

I wanted to make a quick post regarding new crush depth changes in the latest (and now published ) version of TM.


I greatly increased the crush depths of all fleet boats. The earliest boats have a shallower crush depth, the later models have a deeper crush depth.

The order of evolution in sub design is, from shallowest crush depth, to deepest crush depth is:

Narwhal
Porpoise
Salmon
Sargo
Tambor/Gar
Gato
Balao
Tench


While crush depth has been greatly increased, it is not as deep as i could have made them. My primary limitation in that regard was some quirky buoyancy physics that are encountered at deeper depths. So i had to curtail myself around that.

I will not EVER hint, or tell anyone what the acutal crush depths are, so don't ask me.


But, here is the main point of this post. Reaching crush depth now, IS FATAL. If you find out what depth your boat crush's, you will not live to tell about it. (at least if you play " Dead is dead" )

You also should know that your acutal crush depth is vary, depending on the condition of the hull. If your at 100% hull integerity, your boat will be able to survive the maximum depth that i set it at, until you reach crush depth, at which point you have about 3 seconds so before your undamged hull becomes 100% damaged. Which is about as much time as is required to put your head between your legs and kiss your buttocks goodbye!


If your boat is damaged, then your crush depth will vary according. Lets say for example you have incurred 25% damage on your hull. Or in other words your hull is 75% of what it used to be. Your crush depth will accordingly be 25% less, or 75% of its undamaged total.

Now since you really wont know your acutal crush depth until its too late, this turns things into a **** shoot when diving an damaged boat. Lets say for example youve taken your boat as deep as 400 feet. You know you could go deeper (cause your still alive), but you dont know how much deeper. If your hull has 25% damage to it, then you know that you just lost 25& of your depth capability, and you also know that your boat will crush at 75% of its undamaged total. You could dive saftley to 300 feet in this example since thats 75% of your known total. You could go deeper, but your taking a big gamble because you don't know your total crush depth. (i hope i havent confused anyone, im pounding this post out in a big hurry before i hit the road and head in to work).


Suffice to say, you can go deeper, but odds are, you won't want to push it too much, particuarlly if your submarine is damaged. If your at 50% damage, whooaoaa nellie, id be afriad to go deeper then periscope depth. Conversely, if your bold, and willing to risk your boat, you can go deeper, but how deep is anyones guess.

Did you pattern the crush depths after US naval specs?

[Ducimus_Rapax]

Patterned after first hand accounts of deep dives, some logical extrapolation, and current limitations in game physics. I can't get into how i hashed it out without revealing numbers, which in the case of crush depth, i just won't do. Its the one thing i deliberatly keep secret in modding. Really spoils things when you know the exact "under the hood" statistics.

Thats cool, Duci, there are lots of accounts of boats going pretty deep, much more than test depth, and presumed crush depth. Historical accuracy is a good thing. Does this mean the chance of detection from both passive and active sonar decreases with depth? as per in game mechanics that is.
Great work, appreciated.

Being at a deeper depth does help one get under a tin can's active sonar beam.

you didnt include the s-class?
but thank you anyway for the upgrade

Salmon and Sargo Classes

I think Kato meant the S-18 and S-42 boats....To me, those are S class, and the others are Salmon/Sargo classes.
