Diving REALLY Deep?

I see in published accounts that O'Kane took TANG well below test depth, and in game, I've survived incredible depths before eventually being crushed. My question is, how can I order a depth that is beyond the maximum portrayed on the gauge? I know the game recognizes greater depths, because they are listed as you sink. Any ideas?

I took a gato class to 450ft. with no problems. game incidates crash deep was 325ft.

Press the 'd' key to execute a dive, then once you reach the desired depth, press 'a' to level out. ;)

Which brings up an interesting point: if the real guage has a limit, how did they know how deep they were? I firmly believe U.S. fleet subs could dive a lot deeper than the official limits, but how did they know?

I suppose you could guesstimate by knowing the divisions on the depth gauge. Like the scene in Das Boot during the Gibraltar sequence when they're at a depth deeper than the gauge shows.

IE:

|...|...|
1...2...3...4...5

That only works to a certain depth however. I don't think the in-game gauge does that.

The answer is here:

Conversion from sea pressure to depth: every 100ft = 44 psi increase in pressure.

:know:

ps. Note that the article above has a math error. 375psi = 852 ft, NOT 750 ft.

Nothing like a direct reference. Thanks, Professor N.

I took a Gato to 768ft before she imploded I got the screen saying that Ive disgraced the navy and been thrown into chains. :hmm:

My poor Tambor class only made it down to about 370ft before imploding.

In the book Clear the Bridge by Richard O'Kane he states that while on sea trials he took the Tang down to 625+ feet. He mentions that the depth gauge pegged out at 600 feet.

While serving on USS Sandlance, SSN-660 the very first watch I stood was monitoring a pressure gauge in the Engine Room Upper level while doing angles and dangles. I was on sound powered phones and was required to read out the pressure at regular intervals during the exercise. Boring as hell and at the time I had no clue why I was doing it (backup to depth gauges up forward). So if WWII subs had pressure gauges it would have been easy for them to keep track of depth using pressure - someone could have just made a table that could have been read from.

"In one action in the Pacific the Tang lost depth control, leaving the control room depth gauge pinned past its max reading of 600ft for a LOOONG time. Long afterwards, when they were both POW's, a forward torpedoman told O'Kane that he saw an external pressure gauge in that compartment go past 375psi (750ft [sic - should actually be 850!] depth), but decided not to tell O'Kane lest he decide the boat was safe to such an extreme depth and use it routinely in battle!"
