I don't see why the amount of compressed air would affect buoyancy. When one spends compressed air to blow the ballast tanks, it is not replaced by anything heavier. Even air has positive weight, and is certainly heavier than vacuum. Having no compressed air left would therefore make the sub lighter, though not significantly. |
My point was simply that without any means of giving the sub positive buoyancy it would sink. submerged U-boats, if they are without ballast, are heavier than the water around them.
