Indian Air Force unsatisfied with Russian R-77 Missiles will replace with Israeli Derby AAMs...

In two years from now, the Indian Air Force's frontline Sukhoi-30 fighters may be re-armed with Israeli Derby air-to-air missiles after the jet's Russian-made R-77 missiles were found wanting in air combat operations over the Line of Control on February 27 this year.
Sources in the Indian Air Force told NDTV, "We already have the missile as part of the SPYDER (Surface-to-Air Missile) system. Integration (with the IAF's Su-30s) is the next step.''

Retaliating to the IAF strike on the Jaish-e-Mohammed training facility in Balakot on February 26, the Pakistan Air Force aggressively positioned a large formation of 24 fighters near the Line of Control (LoC). A handful of these jets managed to cross the LoC to fire precision-guided glide bombs towards Indian military positions in the Rajouri sector.

Wow.  The Indian Air Force is all but saying they had their behinds handed to them by the Pakistani Air Force.

The question is simple.

Are they looking for a scapegoat with the R-77 or is there an actual problem with that missile?

Open source tells us that there were many breakdowns on the part of the Indian Air Force tactically so I'm not sure this is valid.

I wonder what the real back story on all this is.
