Hwacha

• Invented: 1451
• Korean: 火車 (hwacha)

The hwacha (lit. "fire cart") was an early artillery device developed by Joseon Korea, consisting of a cart from which one hundred fire-arrows (K: singijeon) could be launched. Adjusting the angle of the launcher aided in aiming at a target.

Singijeon, developed several years earlier in 1448, were rocket arrows with pockets for gunpowder attached. They were produced in three sizes (small, medium, and large), along with a two-stage type of rocket arrow known as sanhwa singijeon.
