During the cold war (1945-1990) the Soviets probably had the largest sub force.
During WWII the largest submarine was the Japanese I-400 Class sub. It was 400 feet long, displaced 6,000 tons, carried 3 airplanes, and had a complement of 144 officers and men.

The buoyant force keeps a submarine afloat.
The buoyancy force on a submerged submarine equals the weight of the water displaced by the submarine. This force acts in the opposite direction to the gravitational force, allowing the submarine to float or sink in the water.

the worlds largest swamp is the Sudd thx for asking
USA has the worlds largest rail network.
A submarine rotates its turbines in the opposite direction of normal rotation to cause water to be drawn towards the submarine. The force causing the mass to be moved toward the bow of the submarine is counteracted by the force drawing the submarine backwards.
The worlds largest natural magnet is the earth itself.

The United States has the largest air force in the world. Take note, the US Air Force is not the largest air force in the world based on number of Aircraft. The US Navy/Marine Corps has many more aircraft, and the US Army has more aircraft, mostly helicopters, than any of the other individual branches.
