In 1380, an order of "wasp nest" rocket arrow launchers were ordered by the Ming army and in 1400 rocket arrow launchers were recorded to have been used by Li Jinglong. [21] In 1451, a type of mobile rocket arrow launcher known as the "Munjong Hwacha" was invented in Joseon. [22] The Japanese version of the fire arrow was known as the bo hiya.
