Apologies sir, my intention was not to call your expertise to question.
What I was trying to say, is that countering a modern 4.5++ gen jet isn't simply a matter of bringing another jet, bells and whistles notwithstanding.
There are two distinct approaches. The first is the American, air superiority F-22. One plane, with all bells and whistles. The problem is, if you load a single plane with so many requirements, there will definitely be conflict.
As opposed to this, the Russian strategy in Syria has been to keep their air superiority fighters at a basic 4+ gen level. Most of the planes were strike fighters, or multi-role. They fielded only a handful of air superiority fighters. Their major assets were the A-50U, and S-400. The A-50U takes away the advantage of look first, shoot first from the F-22. It can no longer claim to see you while you don't see it. It can no longer claim to unlockable. All you need, is any platform - not a 5th gen fighter, but any platform - that is capable of firing a VLRAAM. This Russian strategy is tried and tested in Syria, and I feel is a very potent one.
