You are referring to the bouyancy ballast tanks - diphead!

That is
*not* "the ballast". Equivalent to a diver's BCD.



diphead? My my, getting a bit testy, are we?



c.
Without the ballast at the bottom of a sub (as said, I believe

it will
be Lead (or DU for modern war subs)), OR the construction

itself -
producing a vessel that is denser than water (mass/volume) -

the sub
will not sink!



Oh, right, I keep forgetting, water weighs zero in Doe Doe land.
