Hey there, fellow naval enthusiasts! I'm a supplier of Batleship Armour, and today, I'm super stoked to dive deep into one of the most fascinating topics in naval history: what was the maximum thickness of battleship armour ever built?
Battleships were the kings of the seas for a long time, and their armour was a crucial part of their design. It was like a shield, protecting these massive vessels from enemy fire and making them a force to be reckoned with. Over the years, naval engineers and designers were constantly pushing the boundaries to make battleship armour thicker and more effective.
Let's take a little trip back in time. The concept of armouring ships dates way back, but the real evolution of battleship armour started in the 19th century. Before that, ships had relatively thin wooden hulls that could only withstand so much. But with the development of more powerful cannons and explosives, there was a need for better protection.
One of the early attempts at armouring ships was the use of iron plates. These were a significant improvement over wood, but they still had their limitations. As technology advanced, steel became the material of choice for battleship armour. Steel was stronger, more durable, and could be made in thicker plates.


Now, let's talk about some of the battleships that had some seriously thick armour. The USS Iowa class battleships are a great example. These ships were built in the 1940s and were some of the most powerful battleships ever constructed. Their main belt armour, which is the thickest part of the ship's armour, was about 12.1 inches (307 mm) thick. That's like having a wall of steel protecting the vital parts of the ship from enemy shells.
But the USS Iowa class wasn't the only battleship with thick armour. The Japanese Yamato class battleships were even more heavily armoured. The Yamato and her sister ship, the Musashi, had a main belt armour that was a whopping 16.1 inches (410 mm) thick. That's almost as thick as a small car! This thick armour was designed to withstand the powerful shells fired by other battleships.
The reason for such thick armour on these battleships was simple: to survive in a naval battle. In the days of big guns and long-range engagements, a battleship needed to be able to take a hit and keep on fighting. The thick armour helped to absorb the energy of enemy shells and prevent them from penetrating the ship's vital compartments.
Of course, there were trade-offs to having such thick armour. The extra weight of the armour meant that the battleships were slower and less manoeuvrable. But in the minds of naval strategists, the protection provided by the armour was worth the sacrifice in speed and agility.
As technology continued to advance, the design of battleship armour also changed. New materials and construction techniques were developed to make the armour more effective without adding too much weight. For example, composite armour, which combines different materials like steel and ceramics, became more common. This type of armour could provide better protection against a wider range of threats.
But despite all the advancements in armour technology, the era of the battleship eventually came to an end. The development of aircraft carriers, submarines, and guided missiles made battleships vulnerable in new ways. These new weapons could bypass the thick armour and strike the battleships from unexpected angles.
However, the legacy of battleship armour lives on. Even though battleships are no longer the dominant force on the seas, the technology and knowledge gained from their design are still relevant today. The principles of armour design are used in other applications, such as Cruiser Armour and even in the protection of land-based vehicles.
