Shahed-136 drones, which Iran sold to Russia, are equipped with engines of German technology stolen almost 20 years ago.
According to CNN, the British organization Conflict Armament Research studied the details of 20 Iranian drones taken from Ukraine from November 2022 to March 2023, half of which were Shahed-136.
The engine research shows that Iran, despite international sanctions, has made significant efforts over the years to apply Western technology to its drones and missiles.
