All modern submarines are "dual hull" constructed. What you see on the surface is the outer hull, or "superstructure". The inner hull, where the main systems and crew are, is protected by the outer hull.
Damage severity of either the outer or inner hulls depends on the boat's depth at the time. If deep enough, it doesn't take much damage to the hull, as sea pressure will be virtually unstoppable, even with the quick-reaction damage control skills of a submarine crew.
However, if sea pressure isn't a factor and the flooding can be controlled, then it's possible to survive such a casualty. Again, it depends on the severity of the hull breach, and the depth at the time.
Several modern submarines (my old boat included) have survived underwater collisions which produced severe damage.
The water would rush in and sink the sub. The pressure would equalise rapidly and when it does, the people inside would be crashed if they were too deep.
The hull is the outer shell or the metal skin of the submarine that protects the inner area from the outside water.
Yes, water exerts pressure on the hull of the submarine.
A casing deck is another term for a submarine's superstructure hull, which is the outer hull that protects the inner pressure hull. Using a thermos bottle as an analogy, the inner container where liquid goes would be the pressure hull, and the outer case which protects it the superstructure, or outer hull.
No, the body of a submarine is not typically referred to as a "fuselage." The term "fuselage" specifically describes the main body of an aircraft, while the corresponding term for a submarine is "hull." The hull is designed to withstand underwater pressure and provides the submarine's structural integrity.
The sub could sink so deep that the water pressure would crush the hull, and all hands would perish.
Submarine hulls are subject to sea pressure, and that pressure increases the deeper the submarine goes. There are design limits to the amount of pressure that a hull can take, and if that pressure is exceeded by diving too deep, the hull will fail and will be crushed.
because if a submarine goes under water to deep levels, it needs to hold against the air pressure. Yes the person said above.. They have to have a MUCH higher ability to withstand the pressure of the water pushing in against the hull of it.
No, perhaps you are thinking of a ruptured epidermoid cyst (skin cyst) or ruptured appendix which can happen with appendicitis (inflammation or infection of the appendix in your intestine).
The air tanks on a submarine are typically located in the ballast tanks, which are distributed throughout the submarine's hull. These tanks are used to adjust the submarine's buoyancy by filling or emptying them with air or water.
Submarine TITANS happened in 2000.
Battle Submarine happened in 1995.
