How can one dive deeper than 450 ft (on purpose)? It is not possible to set a greater depth than 450 ft or am I missing something? When I hit the "D" key for normal diving the boat just won't go below test depth. I hear others here on the forum saying things like "I took her down to 600 ft..." etc.. How are you guys doing this?

You press C then when you reach the right depth level out by pressing A.

I thought the "C" key was for crashdive? Usually automatically levels the boat off at 150ft.

Hello, thanks for the replies but none answers the question.

"C" brings the boat only to a depth of 150 ft.
"D" puts the boat to dive normally but levels it out at test depth.

I would like to go below 450 ft, how are you doing that?

Crash Dive and Dive depths are specified in the data\Submarine\NSS_<boat_type>\NSS_<boat_type>.cfg files.
The depths are in Meters. 1 Meter = 3.28 feet approximately.

Since I haven't used RFB as of yet, does the mod allow for boats to go deeper than the redline "testdepth"?

The mod I use does allow for you to go deeper, but just how deep until the boat crushes? You won't be heading back to base if you do find out how deep your boat will go before it does crush. The redline for testdepth wa just a depth that the design had been tested to. The boats were able to go deeper than the redline. But things like age and damage would affect just how much farther a skipper dared to go.

Here is what I tried so far, I set the MaxDepth in the the submarinename.cfg to 1,000 meters which will allow me to dive deeper but you have to stop the descent by pressing "A" in time or you will crush, I found that out. An unwanted effect is that the red marker in the depth gauge will go to its maximum and I loose all the warnings and comments by the crew that I am below test depth etc. but the boat does implode. Is there a depth gauge which goes until 600 or 700 ft somewhere what I have not found yet? Come on, there must be a way to dive deeper than 450 ft. Every commander in WWII had this option and probably used it more than once. Is the "Maker" of RFB still around, maybe he knows...

The Gato Interior had Depth Gauge in Conning Tower that displayed deeper depths. Not sure if it is still there.

The Gato Interior is used for Gato, Gar, Tambor, Balao, Tench

Are you sure, in RFB? I cannot find it, was looking for it exactly there...

Mido, everybody I know of that takes their boat beyond the testdepth, and passed the 450 mark, uses TMO. It has a 600ft depth guage you can click on. So if I want, I can click to take my balao boat to 600ft. trouble is though, the deeper you go, the tougher it is to get back up again. Even at 600ft, if I slow to 2kts, the boat slowly goes deeper passed 600ft. You have to increase speed to maintain depth, or rise to shallower depths, without blowing the tanks.

But not every boat can do that. The earlier boats had shallower test depths, so even going to 400ft with them can be iffy. I have taken the boats with a 250ft testdepth to 375, and a couple times to 400ft, but it gets a lttle nerve wracking. I did take a balao once to 700ft, but couldn't get her to rise, until I went to flank speed and blew the ballast tanks. Almost didn't come back from that once. Not sure what the game does, but once you start to hit those depths, the water is like glue. Almost going through gelatin.

Thanks Hylander, finally I figured out what changes to make in the relevant *.cfg files and my fleet boats can dive until they crush now. I really like RFB + RSRDC and if somebody could produce a mod which would allow you to dive down to 600 ft and more in a controlled way, that would be a big plus, also for TMO. It is historically not correct that the submarine would sink like a stone once past 500 ft of depth.

Default Dynamic Lift

Hylander ... I don't know if the continued falling at low speed was intended in the game, but in real world, it can be a result of losing "Dynamic Lift" .

That was the physics principal that allowed a Zeppelin to lift in the air without adding gas or letting ballast go.

Sub in water works the same way (I think!?)

Anyway, something to look up in WIKI

Yes and no. I assume that "dynamic lift" involves moving forward at an angle that generates lift.

A sub in the water has to be balanced in a daily test dive. It was possible to come close to neutral bouyancy, but almost never perfectly. This is achieved by pumping water in the trim tanks until the boat is balanced as close to perfectly as possible. Once done you should be able to dive the next time without worrying. Problem is that by "the next time" you have expended fuel, making the boat lighter, people have eaten, which makes the boat lighter, if only by a few pounds. So on every dive you have to adjust for that. And now the clincher: every boat, every ship, no matter how "watertight", leaks. The more time you spend underwater the heavier the boat becomes. The only way to handle this is by moving quickly enough that the dive planes can respond, which makes you noisier, or by using the pumps to adjust the trim or pump some water overboard, which is also quite noisy.

There is no compromise, the boat is never perfect, and you have to deal with it somehow, and that almost always involves making noise, which is what you don't want.

There is also the temperature and salinity of the water, causing the water at different depths to have a different density, and I almost forgot, there is hull deflection due to the pressure.
