The "K" does have many of the avionics upgrades I'm talking about, but no it is not close to the total package I discussed. Would the USAF suggest such a thing? No. But after they have the Raptor, more aren't forthcoming, and the F-15 airframes hit a wall, they might consider it.
In any event my point wasn't what I thought would happen, just what I thought was feasible. The Russians have certainly upgraded the basic Flanker into another level of capability.
Actually,the Russian super Flanker upgrades really show what will happen to a souped up F-15.It will be loved by the export customer,but almost completely ignored by the mother airforce.
How many SU-30/35s has Russia purchased???The only new Flanker variant that Russia is buying in any decent quantity is the SU-34 medium bomber & that too because of the age of the SU-24.The SU-35 in it’s new avtars is an excellent aircraft-probably only behind the F-22 in all round capability,but nobody wants it.They seem content to upgrade their existing fleet & wait for their 5th generation fighter.Pretty similar to the USAF approach.
