Turtle ships participated in numerous victories against [[Naval history of Japan|Japanese naval forces]] that supported [[Toyotomi Hideyoshi]]'s attempts to [[Japanese invasions of Korea (1592–1598)|conquer Korea from 1592-1598]], inflicting heavy losses. However, their historical role may have been exaggerated since "the entire Korean fleet probably did not have more than half a dozen turtleboats in action at any one time".<ref name="Swope 2005, 32"/> Korean [[admiral]] [[Yi Sun-sin]] is credited with designing the ship. His turtle ships were equipped with at least five different types of cannon. Their most distinguishable feature was a fully covered deck that was shielded to deflect cannon fire, and with iron spikes to discourage enemy men from attempting to board the ship.
