How Does A Submarine Dive, Resurface And Navigate Underwater?
WEBOct 19, 2023 · In order to control the buoyant force acting on it, a submarine fills/empties itself with the surrounding water to dive/resurface. A submarine consists of ballast tanks (and trim tanks too, in some models) that can be filled by either water or air according to navigational requirements.
