Just gonna say my pov on this matter.
1) Ispr was vague about many things. Not naming the projectile or clearing it to be missile or drone. Or was it shot down or not.
2) Now why would India do this?
So, from the pictures here it was brahmos and it also collaborate that it was moving at supersonic speed.
Secondly many fellows here especially
@Salza are of view that it was not shoot down or where was our AD. Ispr has said it engaged the missile with standard SOPs and has provided the tracking data so our radars detected it even in Indian territory.
Now, why didnt we shoot it down? Ispr has deliberately not said anything about it shooting down but people from the area said they heard TWO explosions. One can guess that Pakistan didnt want to disclose its capabilities because of military hypersecrecy policies.
Second why would India do this. Two possibilities either failed test or to check our AD. Anybody with mechanical or electrical eng knowledge who has know how of control systems would know that missile stabilization is a one of the most imp task. So if it was a failed test missile guidance system would not have been able to stabilize it to be in air and it should have crashed imediately. The way it followed its trajectory seems to me that it was delibrate.
Now our response can and will only be diplomatic as much as i want our military to react in similar manner we simply cannot as 1. it would escalate and with current global crisis we would seem to be aggressor and 2. we are not 100% sure that it was deliberate. What we can do is study the material which can withstand supersonic speed, engine design etc.
