SSN (hull classification symbol) - Wikipedia
WEBSSN is the US Navy hull classification symbol for such vessels; the SS denotes a submarine [1] and the N denotes nuclear power. The designation SSN is used for interoperability throughout NATO under STANAG 1166, [2] though navies use other terms.

WEBA submarine or a ship can float because the weight of water that it displaces is equal to the weight of the ship. This displacement of water creates an upward force called the buoyant force and acts opposite to gravity , which would pull the ship down.
Ballast tank - Wikipedia
WEBA ballast tank is a compartment within a boat, ship or other floating structure that holds water, which is used as ballast to provide hydrostatic stability for a vessel, to reduce or control buoyancy, as in a submarine, to correct trim or list, to provide a more even load distribution along the hull to reduce structural hogging or sagging ...

Naval architecture - Weight, Buoyancy, Stability | Britannica
WEBA ship floating at rest in calm water is acted upon by two forces, weight and buoyancy. Weight is the downward force on the ship. The total weight force (W) acts on the ship as if it were concentrated at the balancing point or the centre of gravity (G). Buoyancy is the upward force of all the hydrostatic pressures on the hull.

Here’s the science behind how submarines dive and resurface
WEBOct 22, 2020 · Submarines use ballast and trim tanks, which are filled with air or water to submerge or raise the ship. When the submarine is floating on the surface, the tanks are filled with air causing its density to be less than the surrounding water.
