The General Atomics MQ-9 Reaper unmanned aerial vehicle (UAV) has become the staple of USAF drone operations.
China has produced a copy of the system, which it dubs the Wing Loong II. It's reported that Saudi Arabia has ordered up to 300 of them, because they're sold with far fewer restrictions than US drones. The Wing Loong II is clearly a close copy of the Reaper in many respects, and has now been tested with Chinese versions of similar weapons to those carried by the Reaper. Here's a Chinese publicity video showing the tests.
Clearly, the virtual US monopoly over high-end drones - at least those intended for use in areas where there are no major air defenses - is over. My worry is, if a country like Iran gets its hands on similar equipment, will it try to use them to turn the tables on US forces in countries like Afghanistan or Iraq?
