Hwacha
About “Hwacha”:
The hwacha or hwach'a was a fifteenth-century Korean weapons platform capable of performing both the multiple rocket launcher or a volley gun roles. The overall design resembled a wooden cart with a launch pad attached; depending on the specific version and type, it could fire up to 200 singijeon (rocket-powered) arrows, or several dozen iron-headed arrows or bolts out of gun barrels. The term was also used to refer to other war wagon- or cart-based artillery in later periods, such as that developed by Byeon Yijung in the 1590s.
