Gunpowder rocket
Gunpowder-propelled arrows become the first rockets, fired at the siege of Kaifeng.
Song and Jin forces used gunpowder-filled tubes that propelled arrows, with records from the 1232 siege of Kaifeng. Rocket knowledge spread to Korea, India and Europe. Mysorean iron rockets in the 1790s inspired Britain's Congreve rockets and, eventually, modern rocketry.
