Better Radar?One forgets the MiG-31 "Foxhound", which can detect stealth airframes.
While not a "fighter" per se, it does have a respectable data-link capacity that is compatable with "Fulcrums" and "Flankers."
Hence the well deserved nickname "Mini-AWACS." You did not mention this jet in specific, yet, the "Better than any MiG or Su" does qualify its entry.
And that statement is debateable with reguards to the latest generation of MiG-29's and Su27/30's.
As far as Aerodynamic coeffiecnt.
An Airframes "cruse" velocity with respect to aerodyanmics, is determined by two sets of curves.
The Raptors turbofans posess the closest ratio of "Full Military" to "Full Afterburner" yet seen.
This is an engineering accomplishment, as well a testament to manufacturing and quality control. As the engine can hold-up under such stress.
As far as a miracle or new definition of physical laws? No.
Not that you have stated this, but, others have hinted.
For the records:
The MiG-29OVT (AKA MiG-35) and the Su-30MKI both have thrust vectoring. A Discovery channel show produced by the USAF and various defense contractors admitted, Russia does have an edge in TVC design.
Which is not to say the US or any other nation cannot produce excellent units.
The Su-30's used in Cope India, were not MK or MKI. In fact they were not even full spec Su-30's.
What were they?
Mod'd two seat Su-27's.
In Cope India. The IAF used mostly latest edition MiG-21bis's. For reasons of clairification I add this.
The "bis" designation is a varient of the French word for second, not, as some "experts" call it "Bison", that label belongs to a 50's/60's soviet bomber.
As far as the Raptor in Cope India?
Right, it would have made a huge difference in the outcome.
Then again so would have 30MKI's and Full spec 30's.
