Chinese are unable to copy the Iranian drone (Shaheed 136) hence were forced to order the said number from Iran. This highly successful drone of Ukraine war cost only $20,000 but required a $3 million missile to shoot it down. Ukraine did not care much about cost of the missile as everything was free. In the end Russia ran out of its supply. Moreover, it was not accurate enough to target a specific location, hence the Russians discontinued It’s use.
Why China wants such a drone in so many numbers (15,000) knowing fully well that the device is inaccurate……. Anybody’s guess.
Guessing that some of these drones will be transferred to the Himalayan LOC region, that will require a defence against them. First defence that snow covered peaks play a havoc on its already low level of accuracy. Second, its payload is two small to be effective against forward areas. Third, it cannot hit on reverse slopes where most of Indian defences are located. That makes their presence at LOC much less effective, even though a swarm of these is fired.
Shaheed 136 is a terror weapon for civil structure destruction. The width of Himalayas is about 200 miles, hence it cannot reach any urban areas in the region.
