A common myth in the Pakistani community is that the AMRAAM wreckage recovered in India shot down a phantom SU-30MKI. It’s wildly excepted on PDF especially by senior members such as Windjammer. Here we go dispelling that propaganda with proof.
First off, the AIM-120 travels at Mach 4 and has a high explosive warhead. Naturally it will turn into debris even if it fails to hit any aircraft due to sheer force from impact, explosive warhead and the velocity.
The below image depicts the wreckage which is flattened out. This is common with aircraft or missiles that hit the ground horizontally with enough force. For reference a Mig-29 shows a similar effect. The size of the AIM-120 is also rather large, approximately 3-3.5 feet or about 0.914 meters, rather unusually large if it impacted an aircraft at Mach 4.
Here is a better understanding of where the missile wreckage came from and where the warhead sits. If anything the missile would be crushed similar to a tin can and break up in small pieces instead of having such large, well preserved wreckage especially wreckage that is flattened. It is therefore without a shadow of a doubt that the AIM-120 impacted the ground with high force hence the flattened effect.
