. As
one senior U.S. Marine Corps aviator told me, the S-300 series is deadly. “A complete game changer for all fourth-gen aircraft [like the F-15, F-16 and F/A-18]. That thing is a beast and you don’t want to get near it,” he said.
One S-300 battery is a handful,
but several such systems networked together into an integrated air defense system is a nearly insurmountable challenge for most fourth-generation fighters like the F-16 or F-15
This is S-300 but India will be getting S-400 system with 6000 missiles which a F-16 has very little chance of penetrating.
Also India has the worlds much advanced AWACS systems with the Phalcon that will be able to detect further into Pakistan territory, depending on the location of PAF bases it can spot a F16 taking off which will alert the air defence systems in place.
SU-35 will not be available for PAF, India would lobby the Russians (we have bigger defence budget) the best option is a Chinese 5th gen fighter in my view.
