Frightning! No sub skipper wants to hear this.

It sounds like when I flush my toilet (after a particularly heavy dinner)

Ohhh ... Ooomph!

[Hartmann]

I heard time ago another tremendous sound.

it was recorded with a sonorbuoy launched by an aircraft, the noise of the sub propellers and the blast of the Fido torpedo.

The next sounds are the air scaping of the ballast tanks and the gurgling water, finally the hull collape and loud explossions, probably the compartments crushed by the water pressure.

At least you die quick on a sub.

yes, the bad thing is the time before you die, when you can hear the noise of the hull being crushed...

Not quite true, in my war patrol nº 20 (March, 17 1942 at 14:22 game time) with a type: VIIC i was attacking for the second time a large convoy, South of Iceland when i was attack at the PD by a Destroyer. The deep charges attack cause a heavy flotting in: stern quarters, diesel engines, and stern torpedo room. The U-boat starts to sink very fast, at the same time i put my crew at work in the repairs with main objective to stop the heavy flotting, with repairs is carring on, minutes later we passe the "red line" of the 160 m (i think to myself its over now if i coundnt stop the heavy flotting very son i will crash by the deep) the U-boat countinued to go down, with out stoping the heavy flotting, minutes later we are at 260 m and countinued to go down, with the U-boat holding the pressure (at this time i was very very nervous about all this stress for my surprised i still alive and all so my crew) and minutes later we crush the ocean floor with a tremendous noise!
When i check the deep we are at 503 m deep! i coundnt belive in my eyes...503 metres and the U-boat still intact, my crew countinued to work and we are able to control the heavy flottting, but my happiness runs out when i checked the damege areas, the report was: two electric engines destroyed, compressor destroyed, and one diesel engine destroyed. It was the end...i see the clock and it was 14:30 even with this critical situation i order to blow balast untill no air left but with out any results at all the U-Boat dont move a inch...i was buried alive in the sea floor at 503 meters bellow the surface! The pressure was so hight wich it wasnt possible to go no where, twenty four hours later we are all death because the lack of air. Even in death you cant have a choice to have a fast or slowly death, the death is certanly but no one nows how gona die!

That is one of the scariest sound files I have ever heard, just gotta add Depth Charge blasts and Active Sonar pings to it...

wow!! 503 meters.

Did you wait until all water was pumped out of the boat before blow ballast tanks?? and check the situation of the damage and repair team ?:hmm: (no silent running activated).

Perhaps the water pressure is too strong and the tanks can´t be blow, asuming that the game engine model this factor.

but think about the good things, you enigma machine and codes are well protected under several tons of water in a iron coffin.and your crew perform like real heroes of the kriegsmarine.

Modern subs can launch a buoy for mark his situation for rescue operations but in WWII...

The recording of Bogue's attack on I-52 is located here http://hnsa.org/sound/index.htm in 2 parts (this is after she sunk though)

The "Expendable Radio Sonobuoy Training Records" have recordings from the actual attack on I-52

Hiii

Yes, i only actived the blow ballast after the water was pumped out of the U-boat, as all so the repairs are complete, it was a "das boot" repairs style! lol
and the silent running was turned off since the first minute after we start to sink.
My opinion its the same as your...the water pressure it was to strong.
Oh yes the enigma machine and all the code book are very safety inside of the "iron coffin" at 503 m under the surface with 49 "ghosts" protecting her!

P.S. But one thing im sure...nobody makes such good and strong U-boats as the Germans did!

Was that the Japanese sub heading to Germany?:hmm:

Correct !!

It was the I-52 japanese sub in route to germany with a cargo of strategic metals, like molybdenum, tungsten, gold and opium and some japanese engineers.

i don´t remember the link but exist a recorded tape with th sounds. :hmm:
