A joint team of underwater archaeologists has located the remarkably well-preserved remains of a Goryeo Dynasty warship in the silt off South Korea's Jindo Island. The vessel, which predates the famous Joseon 'Turtle Ships,' features a unique double-layered timber hull and was found carrying a significant cache of early bronze cannons and iron-tipped projectiles.
Marine researchers state that the oxygen-depleted mud helped preserve the organic materials, including silk sailors' uniforms and wooden supply crates. Analysis of the ship's construction suggests it was a specialized patrol vessel designed for defense against pirate raids, offering new technical insights into 14th-century East Asian naval architecture and ballistics.
