It is unknown precisely how many of Admiral Yi's Turtle Ships were constructed. The cost of one of these armored warships would have been high, especially if the deck was lined with hexagonal iron plates as some sources suggest.
Structure
Many different versions of the turtle ships served during the war, but in general they were about long, and strongly resembled the panokseon's bottom structure. The turtle ship was technically a hull that was placed on top of a panokseon with a large anchor held in the front of the ship and other minor modifications.
On the bow of the vessel was mounted a dragon head which emitted
sulfur

smoke to effectively hide its movement from the enemy in short distance combat. The dragon head, which is considered the most distinguishing feature of the vessel, was large enough for a cannon to fit inside. The dragon head served as a form of

, with the aim of striking fear to the enemy. Early versions of the turtle ship would burn poisonous materials in the dragon's head to release a poisonous smoke.
In the front of the ship was a large anchor. Below the anchor was a wooden crest that was shaped like a face, and these were used to ram into enemy ships.
Similar to the standard panokseon, the turtle ship had two masts and two sails. Oars were also used for maneuvering and increased speed. Another advantage the turtle ship had was that it could turn on its own radius.
The turtle ship had 10 oars and 11 cannon portholes on each side. Usually, there was one cannon porthole in the dragon head's mouth. There were two more cannon portholes on the front and back of the turtle ship. The heavy cannons enabled the turtle ships to unleash a mass volley of cannonballs (some would use special wooden bolts several feet in length, with specially engineered iron fins). Its crew complement usually comprised about 50 to 60 fighting marines and 70 oarsmen, as well as the captain.
Sources indicate that sharp iron spikes protruded from hexagonal plates covering the top of the turtle ship. An advantage of the closed deck was that it protected the Korean sailors and marines from small arms and incendiary fire. The spikes discouraged Japanese from engaging in their primary method of naval combat at the time, grappling an enemy ship with hooks and then
boarding it to engage in hand-to-hand combat.
Korean written descriptions all point to a maneuverable ship, capable of sudden bursts of speed. Like the panokseon, the turtle ship featured a U-shaped hull which gave it the advantage of a more stable cannon-firing platform, and this ability to turn within its own radius was useful to attack enemies by spinning at the same spot using cannons mounted on the four sides of the turtle ship as cannons in those days took considerable time after firing and before cooling and reloading. The main disadvantage of a U-shaped bottom versus a V-shaped bottom was a somewhat slower cruising speed.
Later Turtle Ships held some structural changes as opposed to earlier versions.
[Holz, Heidi. "Complementary Keys to Naval Victory." Naval History, August 2009. pp. 52] For example, later iterations of the Turtle Ship had a higher bulwark height.
This alteration in the design was made so that more bulwark slots could be added.
In turn, these slots could be used for additional weaponry or ventilation for the vessel's occupants.
Early illustrations also show initial versions of the ship consisting of overlapping planks on the deck structure, while later depictions show the deck of the vessel covered with flush, hexagonal plates made of wood or iron.
Nonetheless, in both earlier and later versions, the Turtle Ship was designed to be surprisingly fast, as it was both oar and sail-powered.

There are sources that state that the turtle ship was covered with metal plates,
making the first known ship of this kind in history.
Sources that question claims of iron plating also exist.
While it is clear from the available sources that the roof of the ship was covered with iron spikes to prevent boarding,
[Turnbull, Stephen: ''Samurai Invasion. Japan’s Korean War 1592-98'' (London, 2002), Cassell & Co , p.244] there is split opinion among historians on whether the turtle ship was iron clad.
[Hawley, Samuel: ''The Imjin War. Japan's Sixteenth-Century Invasion of Korea and Attempt to Conquer China'', The Royal Asiatic Society, Korea Branch, Seoul 2005, , pp.192–199][Roh, Young-koo: "Yi Sun-sin, an Admiral Who Became a Myth", ''The Review of Korean Studies'', Vol. 7, No. 3 (2004), p.13]
One Japanese chronicle mentions a clash in August 1592 which involved three Korean turtle ships "covered in iron."
However, according to Samuel Hawley, this phrase does not necessarily indicate that Koreans covered the vessels with iron plates; it could refer to the iron spikes protruding from their roofs, a fitting described for the first time three weeks earlier in Yi Sun-sin's diary.
[Hawley, Samuel: ''The Imjin War. Japan's Sixteenth-Century Invasion of Korea and Attempt to Conquer China'', The Royal Asiatic Society, Korea Branch, Seoul 2005, , p.602] Stephen Turnbull, however, points out the fact that in February 1593
the Japanese government ordered the military to use an iron plate in building ships, possibly in response to the Korean attacks.
There are no contemporary Korean sources from Yi Sun-sin's time that refer to the turtle ship as ironclad.
[Hawley, Samuel: ''The Imjin War. Japan's Sixteenth-Century Invasion of Korea and Attempt to Conquer China'', The Royal Asiatic Society, Korea Branch, Seoul 2005, , p.195–197] Admiral Yi Sun-sin himself makes no mention of such a design in his comprehensive war diary.
His nephew Yi Beon, who also witnessed the war and left a historical account of the events, do not mention iron cladding either.

even explicitly described the turtle ship as "covered by wooden planks on top".
There is also the question of motivation for adding metal plating. Since the Japanese did not commonly employ cannons on their ships until decades later,
let alone use
plunging cannon fire, any plating would have logically been designed as an anti-incendiary measure, not to withstand cannonballs.
The Japanese did commonly use fire arrows and a form of exploding grenades called in naval battles during this period.
As it was, Yi Sun-Sin, who was largely cut off from government supplies throughout his campaigns, found the small amount of fifty pounds of iron worth mentioning in his war diary.
Therefore, Hawley believes that it is unlikely that Admiral Yi would have passed in silence over the estimated six tons (twelve thousand pounds) of iron necessary for even a single outfit.
Such a large amount of iron was equivalent to one ship's entire ordnance and would have probably been considered more helpful in casting additional cannons,
mainly since the Koreans were well aware that Japanese warships were practically devoid of naval guns.
[Swope, Kenneth M. Swope: "Crouching Tigers, Secret Weapons: Military Technology Employed During the Sino-Japanese-Korean War, 1592–1598", ''The Journal of Military History'', Vol. 69 (Jan. 2005), pp. 11–42 (32)] Confronted with a Japanese enemy who relied on small arms fire and boarding tactics,
and faced by the logistical and financial difficulties involved in acquiring such a large amount of iron,
any iron cladding of the Korean vessels have been deemed by Hawley inherently superfluous:
Evidence for an iron-plated turtle ship is found, according to
Stephen Turnbull, in a 1795 drawing of the turtle ship where the shell is shown as being covered by a distinct hexagonal pattern, implying that something is covering the wood shell.
Hawley, however, questions the historical accuracy of this drawing since it departs in important ways from the 16th-century ships, such as its lack of the reported iron spikes (see image) and the different shape and number of the dragons' heads displayed at the bow. The Korean designation "turtle ship" is already attested in the year 1413, for an early type of the vessel which by all accounts did not feature any armor.
Hawley puts forth the hypothesis that the idea of ironclad turtle ships has its origins in the writings of late 19th-century
Westerners
The Western world, also known as the West, primarily refers to the various nations and states in the regions of Europe, North America, and Oceania. returning from Korea.
[Hawley, Samuel: ''The Imjin War. Japan's Sixteenth-Century Invasion of Korea and Attempt to Conquer China'', The Royal Asiatic Society, Korea Branch, Seoul 2005, , p.197f.] The progression from simple comparison to a statement that the turtle ships anticipated the modern ironclad by centuries can be roughly charted in retrospect, starting no earlier than ca. 1880.
Coming in touch with local tales of ancient armored ships in a period which saw the rise of Western-type ironclad warship to global prominence, these authors may have naturally conjured up the image of metal armor instead of a more traditional heavy timber shell.
For instance, during the
General Sherman Incident
The ''General Sherman'' incident ( ko, 제너럴셔먼호 사건) was the destruction of the American merchant ship '' SS General Sherman'' in the Taedong River during an unsuccessful and illegal attempt by the ship's crew to open up trade with ...
, the Koreans initially constructed an improvised turtle ship, which was protected by metal sheeting and cowhides to destroy General Sherman but failed to penetrate its iron hull at the cost of one of their sailors.
When the
French Navy threatened Korea, the government ordered an ironclad ship be built "like the turtle ship."
However, despite all efforts the design failed to float.
Turnbull believes that the 19th-century experience should not rule out a "limited amount of armor plating in 1592".
Weapons
Dragon's head
![Korea-Seoul-War Memorial 2611-06 Turtle Ship Dragon Head](https://upload.wikimedia.org/wikipedia/commons/1/14/Korea-Seoul-War_Memorial_2611-06_Turtle_Ship_Dragon_Head.jpg)
The dragon's head was placed on the top of the ship at the bow. Several different versions of the dragon's head were used on the turtle ships. The dragon's head was first placed as an early form of psychological warfare in order to scare Japanese soldiers. One version carried a projector that could release a dense toxic smoke that was generated to obscure vision and interfere with the Japanese ability to maneuver and coordinate properly.
Yi's own diary explains that a cannon could be fitted in the mouth of the dragon to be fired at enemy ships. This type of cannon was usually a hwangja-

Metal spikes were used to cover the top of the turtle ship to deter boarding tactics used by the Japanese. According to historical records, the spikes were covered with empty rice sacks or rice mats to lure the Japanese into trying to board, since the boarding would appear safe. However, modern authors have found this to be unlikely since such an arrangement would have invited enemy fire arrows.

According to Hae-Ill Bak, one Japanese record of the Battle of Angolpo records the experience of two Japanese commanders on July 9, 1592, in their battle against turtle ships: "their (turtle ships') attack continued until about 6 o'clock in the afternoon by firing large fire-arrows through repeated alternate approaches, even as close as 18–30 feet. As a result, almost every part of our ships — the turret, the passages and the side shielding — were totally destroyed..."
Tactical use
Yi resurrected the turtle ship as a close-assault vessel, intended to ram enemy ships and sink them, similar to their use in past centuries. Despite smaller numbers, disabling or sinking enemy's lead command ship could severely damage command structure and morale of the enemy fleet. After ramming, the turtle ship would unleash a broadside volley of cannonballs. Because of this tactic, the Japanese called the turtle ships because they would blast and ram into enemy ships. This kind of attack was used during the
Battle of Dangpo
The Battle of Dangpo was a naval engagement during the Japanese invasions of Korea (1592–1598) on 10 July that resulted in Yi Sun-sin's victory.

Despite popular depiction, the turtle ship was not an extremely slow ship. The turtle ship had oar propulsion as well as sails, and could turn on its axis like the panokseon. Admiral Yi constructed the turtle ship to be fast and agile for the purpose of ramming.
Turtle Ships played a major role in the Korean victory over the Japanese navy in the Battle of Angolpo (also sometimes called the Battle of the Yellow Sea).
[Ridler, Jason. "Battle of the Yellow Sea." Salem Press Encyclopedia, 2019, pp. 1.] At Angolpo, the Korean fleet of fifty-seven vessels under Admiral Yi Sun-sin faced off against a numerically superior Japanese fleet of one hundred fifty-five ships under Admirals Wakisaka Yasuharu, Kuki Yoshitaka, and Kato Yoshiaki.
Admiral Yasuharu's fleet of sixty-three ships was lured into the Hansan Bay by the outnumbered Korean fleet of warships and Turtle Ships, where it was caught and enveloped in Yi Sun-sin's famous crane formation.
The trapped Japanese fleet was eviscerated by the Turtle Ship's weaponry, and found themselves unable to effectively counterattack due to the Turtle Ship's unprecedented nimbleness and maneuverability on the sea.
Admiral Yi's fleet then attacked the ships of Yoshitaka and Yoshiaki, during which, victory was cemented for the Joseon.
Turtle Ships greatly contributed to the total Japanese fleet loss of fifty-nine ships in the Battle of Angolpo.
