In fact, Iran gained access to American technology and, with the help of reverse engineering, rebuilt it on its own material base. Since the Iranians do not tell much about the technical characteristics, it is difficult to judge how much it is better or worse than the original source. Iran was able to do what the Chinese had previously done, which, based on the technologies used in the MQ-9 Reaper, launched its line of reconnaissance and strike drones of the CH series, where the CH-4 Rainbow most closely resembled the American ancestor, even surpassing it in some parameters and significantly surpassing the original in terms of price, and the CH-5 acted as a further development of the original concept.
Now the Iranians are also following this path, and they are quite confident in copying the American technologies that they get access to.
This allows Iran to remain among the world leaders in the production of reconnaissance and strike drones.
