They were made in what is now Korea but was first under Chinese influence and Mongol control --
"In response to Japan's defiance, Kublai Khan ordered his vassals in the subjugated Korean state of Koryo to build a large fleet of 900 ships and prepare to invade Japan."
I couldn't find a name for these ships

but I did find the Japanese name for -- and ineresting description of -- the explosives they carried at:

"The tetsuhau or bombs discovered on the wreck [from Kublai Khan's fleet - Oz] are the world's earliest known exploding projectiles. Chinese alchemists invented gunpowder around 300 AD, and by 1100, huge paper bombs, much like giant firecrackers, were used in battle. The first reference to exploding projectiles, thrown by catapults, appears around 1221, when Chinese sources describe hollow shells packed with gunpowder. [...] The discovery of not one, but six of these tetsuhau at Takashima has shown that the old samurai was correct. While four of the tetsuhau are broken, two were intact. X-ray analysis of the two bombs shows one was filled just with gunpowder, while the other was packed with gunpowder and more than dozen one-centimeter thick pieces of iron - shrapnel - to cut down an enemy."
As for a name for the magnificent unit itself

how about something mildly ironic like "Divine Wind Ship"?
