Hold on; it is one thing to say that Indian BMs were not intercepted by HQ-9Ps and another to claim that the HQ-9Ps failed to hit them. The latter implies that the PAF air defense network is dense enough to employ its valuable HQ-9Ps in this manner and that an attempt was made by an HQ-9P battery to shoot the missiles down. There is no evidence of the latter.
In fact the only buzz of a so-called "HQ-9 failure" are Indian social media claims, not even official claims, the credibility of which is substantially diminished by the complete lack of photo evidence (no, the photo of the damaged lorry that bears no resemblance to an HQ-9 vehicle is not "evidence").
