Not possible in a U-Boat. In a large surface ship you can seal off a flooded section to restore buoyancy due to it's sheer size but if too many sections flood there gets to a point of no return. The various sections of a U-Boat are proportionally much large than the sections of most surface ships so even one completely flooded room means buoyancy is destroyed and no return to the surface. Plus, it would probably destroy any chance of keeping an even trim.

But I'll repeat my last question - if I don't pump the water, is my boat going to sink?

If a section becomes too flooded you will start to sink,
Sink too far and you'll either hit the bottom opening more holes, or fall below crush depth

when a compartment is completly flooded your boat is classed as destroyed

Thanks guys! It's best not to receive any damage then :shucks:

During the "battle of may Island" debacle in Feburary 1918 K22 collided with K14, both boats were critically damaged. K22 losing it's bow torpedo compartment, K14 everything forward of the control room. Both boats made it back to port, K22 under it's own steam in reverse, K14, more seriously damaged, had to be towed home by a destroyer.
Clearly though this shows that at least larger submarines COULD survive the loss of a compartment, even two in K14's case, provided they were not deep when it happened and they could safely make their escape on the surface. If a ww1 K boat could survive this, I think that a ww2 fleet boat should have been able to, what with their stronger structures. If a smaller boat like a type VII could I do not know.

Actually the uboots even if they sink their inner watertight sections were able to withstand the pressure of the bottom of northsea in order to be raised by friendly forces.Howeever im not sure that such a rescue has ever been attemted.

These days a requarment for all ships is that if their biggest single section is fully flooded they should be able to float, not sure how thing were back in ww2 though.

I don't know about boats lost in action, but there are cases from that era I know of of boats sunk during training or test dives where the surviving crew were rescued from the unflooded sections and the boats salvaged. But this is in shallow, coastal and above all FREINDLY CONTROLED waters.

I had my VII-C's rear quarters flood about 3 quarters after getting hit by a lucky shot while decks awash and the rear of the boat started to sink. Being quite new to the game I thought I'd try and hold the water level there by alternating the damage crew (had other damage) and ordering 40m to get off the surface. Basically, I was able to hold the boat at 40m with a 45 degree angle as the weight held the rear down for about 10 minutes but then she started to sink slowly as I lost my rhythm amongst maneuvers and crew juggling. I managed to straighten her out and get positive climb at 160 meters with steam billowing, lights flickering and nuts shooting across the command room. Our special dinner of beef stew and dumplings was ruined too...

I do hate the instant deaths from these situations though, I wish the effects of going too deep or flooding were better realised, to give that feeling of resigning yourself to death, lol.

God I'm so morbid....

Almost sounds like the death of the Thresher

I can't speak from experience, but I've heard that implosion at depth is a nearly instantaneous death.

Sorry to go off topic, but at crush depth, what would be the first thing to kill a sailor?

I'm guessing if you didn't die of drowning in a flooded compartment on the way down or of being squished by the hull collapsing, you'd die of the sea pressure crushing your body.

Synthfg 05-19-09 06:32 PM

At submarine crush depths
The sudden inrush of water compresses the air in the submarine,
This increase in pressure causes a corresponding increase in temperature (PV=nRT)
This incinerates everything in the sub

In other words the crew are simultaneously squished and burned to nothing,
Death is instantaneous

Unlike for the poor buggers caught, trapped inside a sinking surface ship, where the increase in pressure is usually more gradual and death is a slow painful experience as the air pressure crushes them slowly :o
