First of all there is no evidence of three Rafales down.
Most likely one in Bhatinda and that's it.
It has got to with the RoE followed by IAF that day.
RoE had been not to target any Pakistani military assets. So IAF was focus on nine terrorist sites and surely they were targeted with pin point accuracy.
That's why no BVRs or S-400 were launched though PAF was loitering very close to the border on May7. IAF wasn't playing with PAF that day.
On May 10 IAF sent SCAlps and Brahmos to every Pakistani airbase in tandem to give sample of things to come. We have more than 1000 Brahmos and SCALP, only 15 were used that day. And I'm talking about things verified through Sat Pictures.
According India media report several PAF assets were destroyed.
India used one SCALP and one Brahmos missile in tandem to hit high-value targets in Pakistan so that no target was missed. | India News
