When a submarine is underwater does the buoyant force depend on the weight of the submarine?

Yes, the buoyant force acting on a submerged submarine depends on the volume of water displaced by the submarine, not directly on its weight. According to Archimedes' principle, the buoyant force is equal to the weight of the water displaced, which is determined by the submarine's submerged volume. However, for the submarine to be neutrally buoyant and maintain a certain depth, its weight must equal the buoyant force.
