#37: Korean Turtle Ship: The World's First Armored Warship
In 1592, Admiral Yi Sun-sin deployed the geobukseon, turtle ship, against the Japanese invasion fleet and won 23 consecutive naval battles without losing a single ship. These iron-spiked, dragon-headed vessels were arguably the world's first armored warships, predating European ironclads by nearly three centuries.
The turtle ship's design was brilliantly functional: a curved roof covered with iron spikes prevented enemy boarding, while a dragon-shaped bow could emit smoke or fire to obscure the ship's movements. Armed with up to 26 cannons firing in all directions, a turtle ship could devastate Japanese vessels that relied primarily on boarding tactics. Admiral Yi's naval strategy using these vessels during the Imjin War is still studied at naval academies worldwide. The turtle ship represents one of the most innovative leaps in military technology in Asian naval warfare history.
