Korean access to gunpowder is dated to about 1356, giving the cannon tradition a long pre-Imjin history. Surviving weapons look broadly like iron cannon, although their precise materials remain uncertain. Their ammunition could include stone shot, iron shot, arrows, and large finned wooden darts. The range of projectiles shows that Joseon naval artillery was a developed weapons system rather than a single standardized gun-and-shot combination.
