The world of warships has always been a fascinating one, with the largest battleships often being the most impressive. One of the key features that set these giants apart was their main gun caliber, which played a crucial role in their combat effectiveness. In this article, we'll take a closer look at the 5 largest battleship main gun calibers in history.
The main gun caliber of a battleship determined its ability to deal damage to enemy ships, fortifications, and even coastal defenses. A larger caliber meant more destructive power, but it also came with its own set of challenges, such as increased weight, reduced firing rates, and greater logistical demands. Let's dive into the top 5 largest battleship main gun calibers and explore their significance.
1. 460mm (18.1in) - Yamato-class Battleships
The Japanese Yamato-class battleships boasted the largest main gun caliber in history, with a massive 460mm (18.1in) diameter. These guns were designed to deliver massive shells weighing over 3,000 pounds (1,361 kg) at a rate of two rounds per minute. The Yamato-class battleships, consisting of the Yamato and Musashi, were the largest warships ever built, displacing over 72,000 tons of water.

Design and Development
The Iowa-class battleships were designed to counter the growing threat of the Japanese Navy in the Pacific. The 457mm guns were meant to give the Iowa-class battleships the range and firepower needed to take on the Japanese Yamato-class battleships. However, the project was cancelled due to the end of World War II, and the Iowa-class battleships were ultimately equipped with 406mm (16in) guns.
3. 406mm (16in) - Iowa-class Battleships
The Iowa-class battleships were equipped with 406mm (16in) main guns, which were among the largest in the world at the time. These guns were designed to deliver massive shells weighing over 2,700 pounds (1,225 kg) at a rate of two rounds per minute. The Iowa-class battleships were among the most advanced warships in the world, and their 406mm guns played a key role in their combat effectiveness.
Combat History
The Iowa-class battleships saw extensive combat during World War II and the Korean War. Their 406mm guns played a key role in several battles, including the Battle of Leyte Gulf and the Battle of the Philippine Sea. The Iowa-class battleships were also used during the Korean War, where they provided gunfire support for United Nations forces.
