Yes, the buoyant force on a submarine has been reduced to allow it to "stop floating" and submerge.

How can a submarine float and which force is acting on it?
The buoyant force keeps a submarine afloat.
Do submarines have to do with buoyant force?
The Buoyant force depends on the equation Fb=mfg where Fb is the buoyant force, mf is the mass of the fluid (water) that is displaced by the body and g is the Earth's gravitational constant 6.673x10-11Newton Meters squared per kilograms squared (Nm2/kg2) Submarines use buoyant forces and gravity to move up and down with in the water. When the Buoyant force is less than the Earth's gravitational pull on the submarine, it sinks, when the buoyant force is greater than the Earth's gravitational pull on the submarine, it rises. Once the submarine is already submerged, the buoyant force is constant. Submarines adjust the Earth's gravitational pull on it by filling the space in between the inner walls and outer walls with water and/or gasses. With out buoyant forces, the submarine would never return to the surface of the water.
Which has higher buoyant force submarine near the surface or near the ocean floor?
The force is the same as long as the volume submersed is the same
Will a submarine sink or float when its weight is greater than the upthrust acting on it?
When the weight of any object surrounded by fluid is greater than the buoyant force on it, it sinks. (The buoyant force is just the weight of the fluid that would be in that space if the submerged object were not there.)
What happens to the buoyant force of a submerged submarine when water is taken into its tanks and it dives?
Unless the flooding and buoyancy was controlled, the submarine would continue to dive into the depths, possibly to be crushed by the great pressure of water.
When a submarine pumps water out of its floatation tank its density decreases and it floats. Why does its density decrease?
To rise again, the submarine's weight must be decreased. Air is pumped into the ballast tanks to force the water out. The buoyant force acting on the submarine now exceeds the submarine's weight. With positive buoyancy, the submarine rises. The less weight an object has the more its density decreases. Hope that kinda helps?
What is the relationship between buoyant force and gravity?
buoyant force is always or equal to the force exerted by gravity. that's why an object floats.
How does a submarine change its buoynacy so it can float or sink?
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 at will.
Is the buoyant force of a metal equal to the buoyant force of a wood that has the same mass?
Buoyant force is based upon the mass of the water displaced. Therefore, two objects will have the same buoyant force if they have the some volumes.
What is an buoyant force?
A buoyant force equals the weight of the fluid being displaced
What is the relationship of buoyant force and density of liquid?
Buoyant force is directly proportional to the density of the liquid. as the density of the liquid increases, the Buoyant force increases.
Does the buoyant force on a diving bell deep beneath the ocean's surface have the same value as when the diving bell is just beneath the surface?
Diving bells have no buoyancy=- they are captive and hung from a crane or hoist structure , captive amusement-park ones have something resembling an elevator structure. Therefore if the cable(s) snap, the Bell and its complement will be lost- the air supply is piped in from the surface, they have no buoyancy- so if the lines were snapped- down you go- permanently. Contrast a submarine with ballast tanks.
