Korean Turtle Ship - by How Paper Cafe - Barco de Guerra Antigo

The Real Thing - Replica

The Turtle ship, also known as Geobukseon or Kobukson, was a type of large warship belonging to the Panokseon class in Korea that was used intermittently by the Royal Korean Navy during the Joseon Dynasty from the early 15th century up until the 19th century.

The first references to older, first generation turtle ships, known as Gwiseon , come from 1413 and 1415 records in the Annals of the Joseon Dynasty, which mention a mock battle between a gwiseon and a Japanese warship. However, these early turtle ships soon fell out of use as Korea’s naval preparedness decreased during a long period of relative peace.
Turtle ships participated in numerous victories against Japanese naval forces that supported Toyotomi Hideyoshi's attempts to 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 turtle boats in action at any one time". 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 dragon-shaped head at the bow (front) that could launch cannon fire or flames from the mouth. Each was also equipped with 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. - Wikipedia

Artistic Interpretation Of A Turtle Boat Attacking A Japanese Ship 

Navio tartaruga ou barco tartaruga (também conhecidos como Geobukseon ou Kobukson pelo seu nome coreano) eram grandes barcos de guerra pertencentes à classe de barcos Panokseon, existente na Coreia, usados pela dinastia Joseon entre os séculos XV e XVIII.
As primeiras referências aos navios tartaruga são de 1413 e 1415. Esses barcos eram descritos como "barcos-lança" ou "barcos-ariete" e serviam para furar os cascos barcos dos Jurchen e dos piratas japoneses. Esses navios rapidamente cairam em desuso devido a um longo período de paz durante o qual a Coreia floresceu.
O almirante coreano Yi Sun-sin tem o mérito de ter desenhado e construído os navios tal como os conhecemos hoje. Os seus navios foram equipados com pelo menos cinco tipos diferentes de canhões durante a guerra Imjin. Os navios de Yi Sun-sin tinham o convés tapado e revestido de placas de ferro com pequenos picos. Ele teve entre três a cinco barcos deste tipo enquanto que em 1782 havia pelo menos 40.
