This is wrong and it irks my inner mongol.
It is sadly very but understandibly misunderstood conception of the Mongols.
However mongols were very capable of building ships and eventually formed capable naval forces.
Infact during the siege and battle of Xiangyang (1267-73) in central China, Genghis’ grandson and successor Kublai Khan built a massive navy that transformed his army of Mongol horsemen into a joint naval-ground force. The Mongol riverine navy played the decisive role in the victory at Xiangyang.
This was before the conquest of Goreyo and complete controll over the chinese.
As the campaign in China progressed, Kublai ordered captured Chinese shipyards to begin the construction of 5,000 warships of varying sizes and used Chinese defectors to begin training 70,000 Mongols as sailors and naval infantry. In the coming years, the Mongol fleet would continue to grow in size, and in 1273, following the operations at Xiangyang, Kublai would order the addition of another 2,000 vessels and 50,000 sailors and naval infantry. His Mongol shipbuilding and naval training allowed him to replace the men and vessels he lost in battle and to maintain pressure against the more experienced Song navy.
Yes the mongols incorporated Chinese design into their shipwright.
But this is nothing new and this is what made the Mongol army so formidable.
They adapted and quickly integrated technology that could give them an advantage. And even improved upon them by using the vast accesability of knowledge.
We see this especially in their siege and early use of gunpowder.
Mongol ships actually differed alittle as they improved upon the Chinese design through the help of Arabian engineers. Which is why I think they have the Light Junk as a unique naval unit. Being a hybrid Dow and small Junk. (Using the arab sail technology to improve their ships speed and manuverbility)
And later when they conquered Korea they would implement korean technology to improve upon the Junk designs even more.
In a way yes. Mongols had their own ship technology. But quickly adapted the chinese ones as had elements which were better.
They then took the use of learned menn from across their empire to improve upon the technology
Ofcourse they employed ships from the conquered chinese and koreans, which were common practice of any nation of capturing ships.
Ships have the unique ability that it is always a valuable asset regardless who built them.
So you could in a sence say that the post-mongolian era.
The ships of asia were actually of Mongol design.
Or to be more exact.
Asian design as the mongols simply just improved upon existing designs, this improved design ofcourse became widely employed and replicated and further improved upon as the ages went pass.
So yes.
Mongols were fully capable into Navy, and did not just simply purely use Koreans and Chinese for their navy.
While certainly they employed a lot of koreans and chinese, afteeall they were subjects of the mongols and thus a valuable resource to put into use.
But mongols also had trained sailors and captains fully capable of sailing and commanding fleets.
