While it's underwater, a submarine is negatively buoyant, which means it tends to sink, left to its own devices, if it's not moving But as the submarine's propellers push it forward, water rushes over the planes, creating an upward force called lift that helps it remain at a certain depth, creating a state of neutral buoyancy (floating)

- Diving and Surfacing - How Submarines Work | HowStuffWorks
A 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 Unlike a ship, a submarine can control its buoyancy, thus allowing it to sink and surface

A submarine is a watertight boat that can travel beneath the waves like a ship It comes with water tanks When the sub is about to dive, water is added to the water tanks, making it heavier The submarine’s average density becomes more significant than the density of seawater, causing it to sink
