How thick is a submarine's hull? What material is it made out of?

 

A submarine’s hull is its most important element. It protects the submarine’s crew and machinery from the enemy, while also providing a stealthy profile when submerged. A submarine’s hull must be strong enough to withstand great pressures, while also being thick enough to provide adequate protection. So, how thick is a submarine’s hull? And what material is it made out of? Let’s find out.

The thickness of a submarine’s hull depends on the specific vessel. Nuclear-powered submarines have thicker hulls than their diesel-powered counterparts due to the increased internal pressure from the nuclear reactor. The thickness can range from 10 to 25 cm (4 to 10 inches). However, the specific thickness is classified information.

The material that a submarine’s hull is made out of must be strong enough to withstand immense pressure. The early submarines were made out of wood because it was thought to be stronger than steel under high pressure. However, this was not the case and steel quickly became the standard material for submarine hull construction. Steel is still used today, but it is often reinforced with other materials such as titanium or fibreglass.

How deep can submarines go?

Most people know that submarines can go underwater, but did you know that they can go really, REALLY deep? In fact, some submarines can go down to depths of over 2 miles!

How do they do that? The answer lies in the hull of the submarine. The hull is the watertight outer shell of the vessel that protects everything inside from being crushed by the extreme pressure of the water outside. The hulls of submarines are made from incredibly strong steel that is specially designed to withstand enormous amounts of pressure.

In order to go even deeper, some submarine hulls are reinforced with a thick layer of rubber. This helps to further increase the strength and flexibility of the hull, allowing it to better withstand the immense pressure at great depths. Submarines are also equipped with special air filters that help to keep the air inside the vessel clean and safe to breathe. These filters work overtime at depth to remove any impurities from the air supply.

Conclusion:

A submarine’s hull plays a vital role in protecting crew and machinery, while also providing stealth when submerged. The thickness of a submarine’s hull ranges from 10 cm to 25 cm, but the specific thickness is classified information. The material that a submarine’s hull is made out of must be strong enough to withstand immense pressures and is typically steel reinforced with materials such as titanium or fibreglass.
