Hwacha

Hwacha or Hwach'a (화차; 火車) (fire cart) was a multiple rocket launcher developed and used in Korea during the Joseon Dynasty (1392–1897). It had the ability to fire up to 200 Singijeon, a type of fire arrow rocket, at one time. The hwacha consisted of a two-wheeled cart carrying a board filled with holes into which the singijeon were inserted.
