Iranian sources claim that China has ordered 1500 Shahed-136 drones with 4 different types of engines!
This is not the first time they have made such claims, but it is so far the largest number they have claimed.
In the same post, they also mentioned that 2 new factories have been set up to be able to handle the large number of new orders IRI has received from many different countries (Without mentioning any other names than China).
