How was battleship armor made?
It is designed to keep the ship afloat even if the hull was struck underneath the belt armour by a shell or by a torpedo. After the lessons learned during World War I, many capital ships were refitted with double, triple, or even quadruple torpedo bulkheads, as well as anti-torpedo bulges to the exterior of the hull.

What are battleship hulls made of?
For the construction of the hull of a ship, mild steel containing 0.15\% to 0.23 \% carbon, and reasonably high manganese content is used. Sulphur and phosphorus contents in the mild steel are kept to a minimum (less than 0.05\%) as higher contents of each hamper the welding properties of the steel.
How does ship armor work?
The belt armor is designed to prevent projectiles from penetrating to the heart of a warship. When struck by an artillery shell or underwater torpedo, the belt armor either absorbs the impact and explosion with its sheer thickness and strength, or else uses sloping to redirect the projectile and its blast downwards.
What is cast homogeneous armour?
Rolled homogeneous armour (RHA) is a type of armour made of a single steel composition hot-rolled to improve its material characteristics, as opposed to layered or cemented armour. Its first common application was in tanks.
How thick is a battleship’s hull?
The thickness of the hulls of warships depends on their combat purpose. In extreme cases, it can be from 3 mm for mine warfare ships to even 650 mm on the 1941 battleship “Yamato” [1].
What are the materials used for the construction of ship’s structure hull and machineries?
Steel has been in use for over 150 years in the shipbuilding industry, thanks to its excellent mechanical properties and low cost. For the construction of the hull of a ship, mild steel containing 0.15\% to 0.23 \% carbon, and reasonably high manganese content is used.
