Age of Empires Series Wiki

Rocketry is a technology in Age of Empires II: The Conquerors that is unique to the Chinese and can be researched at the Castle once the Imperial Age is reached. Once researched, it increases Chu Ko Nu attack by +2, and Scorpion attack by +4.


With Rocketry, the attack bonus for Chu Ko Nu and Scorpions causes greater damage to units normally resistant to arrow fire, most prominently Huskarls and Skirmishers, thus in a way can reasonably perform as a substitute for their inability to create Hand Cannoneers or Bombard Cannons.

  • Chinese: Researching Rocketry is 20% cheaper.


The Chinese are credited generally with the invention of the explosive we call gunpowder today. They used it extensively to power rockets, both for entertainment and military use. Although they never developed an accurate design, rockets could be used with great effect against enemies with no experience against these alarming weapons. Rockets were noisy, smelly, and spewed fire while traveling at high velocity. They damaged anything they hit and did collateral damage if they carried an explosive charge.


  • If playing a custom scenario in which a player has access to both Rocketry and (Elite) Ballista Elephants, Rocketry will apply to this unit, granting it +4 pierce damage.
