How quickly do submarines dive?
In a World War II-era boat, the whole operation could take as little as 30 seconds with a well-trained crew. In contrast, an Ohio-class ballistic-missile submarine may take as long as five minutes to reach periscope depth from the surface.

How fast can a German U boat dive?
The latter, which are the most recent and most numerous class, are double-hull boats about 165 feet in length, and are supposed to be able to dive with great rapidity. Maximum speed on surface 13 knots, submerged 8 knots….

How deep could ww1 submarines dive?
Early world War I boats were designed with max depths as little as 150 feet. The idea was that a sub need go no deeper than necessary to get its conning tower below the keel of the deepest draft ships.
Can submarine sink?
Unlike a ship, a submarine can control its buoyancy, thus allowing it to sink and surface at will. To control its buoyancy, the submarine has ballast tanks and auxiliary, or trim tanks, that can be alternately filled with water or air (see animation below).
Do submarines travel faster underwater?
As a result, while the submarine encounters higher hull flow resistance when completely submerged, the screw can operate a higher RPM more efficiently, resulting in a net increase in the maximum speed of the submarine. The deeper the submarine goes, the higher the RPM allowed, the faster it can go.
How many torpedoes could a Uboat carry?
The typical U-boat was 214 feet long, carried 35 men and 12 torpedoes, and could travel underwater for two hours at a time. In the first few years of World War I, the U-boats took a terrible toll on Allied shipping.
What u boat had the most kills?
U-35 alone accounted for 224 ships totaling more than 500,000 tons—most sunk by its deck gun. It averaged nine kills per patrol, making U-35 the highest-scoring submarine of either world war.
How does the buoyancy of an you boat work?
This way, a U-boat is able to control its buoyancy so that it weighs exactly the same weight as the water surrounding it (neutral buoyancy). In this condition, it neither sinks nor float. Thus, a U-boat is able to rise or sink to the depths solely by manipulating its buoyancy.
What kind of propulsion does an you boat have?
U-boat commanders prefer to keep their boat at neutral buoyancy. In this condition, the boat can dive or surface rapidly without constant dependence on the limited compressed air. The main propulsion of the U-boat is the diesel engine – of which there are two, one on each side (port and starboard).
Why was the U-boat called an undersea boat?
For the U-boat force, it was considered as a torpedo boat, with the special capability to submerge for attack or as a defensive measure hence giving rise to the name Undersea Boat or U-boat. Even so, a U-boat is a highly sophisticated vessel of war, with hundreds of precision controls and a 45-man crew to operate.
How is a U-boat different from a nuclear submarine?
Unlike nuclear submarines, which could dive to depths of over 1,000 feet, travel thousands of miles submerged and remain on patrol for months at a time, the u-boat can operate submerged only for brief periods at a time.
