So the waste of ur vera is released to the open ocean?

Yes....  Submariners....compared to other sailors, we contribute to only small percent.

Almost all of us said heavier....which is true. But wrong reason... only u gave the closest answer.

Here is the answer....

As we know fuel oil is lighter than water. When we consumed oil, we cant leave the tank empty. The vapour inside, with the pressure effect can create diesel effect which can cause explosion. So, the avoid that, seawater will be filled inside, hence sub becomes heavier. To compensate, we have to drain some other water tanks. Balancing a sub is a trickier job.....

No difference. Its not a car. The weight of the submarine is supported by the buoyancy of water. You only change the volume of air in the ballast tanks.

do you have time to play phone?

U mean onboard?? Yes.... but only to watch offline movies...like what I did 😊

Do crews still need to run and bunch up at fore / aft during crash dive or surfacing like in WW2 era?

sub don have water maker like vessel on which they can produce clean water from sea water?
