these drones are made in Russia
Source?
And don't tell me it's just because they renamed them.
Well, at least Geran-2 is more accurate than Shahid-136, because it uses the GLONASS satellite system for guidance, and not a commercial GPS.
I mean how do you know that the drones are being manufactured in Russia? Where did you get this information?
What makes you think that these drones are made in Iran and were simply renamed Geran-2? Do you have any proof of this other than allegations? Or the contact fuse of a kamikaze drone does not allow you to study the wreckage of even those drones that managed to shoot down? I pointed out to you above the difference between Geranium-2 and Shahid-136 (another navigation board). This is a significant difference that affects the accuracy of hitting the target.
In addition to Geran-2, Russia also has a kamikaze drone Geran-1 (very similar, but slightly more compact and with a rotary piston engine). The same class of drones also includes the loitering ammunition Lancet, which has recently also been often used in special operations.
