In 2006, the People's Liberation Army unveiled the Tianyan-2 unmanned helicopter, a huge win for the Chinese in the race for drone superiority.
The UAV is designed for use in "high density" environments (cities), is a capable bomber, and was developed by the Armed Police Engineering Institute.
This is one of the very first unmanned air combat vehicles successfully developed by the Chinese, but likely adapted from the Japanese Yamaha RMAX unmanned helicopters.
