The use or not of afterburn to supercruise is important from a IR detection point of view, the 31 would light up the night sky!

This place is soooo full of Raptor fanboys. The F22 will probably never see action , kept at home to protect your shores, god forbid someone shoots one down.

Its a Muscateers hat!

There is no doubt that an HMS may help, but thrust/weight and wing loading are only indicators. Relevant is the thrust/weight, thrust-drag and drag per lift at relevant speeds and altitudes, something that is not visible from the few numbers available at Wikipedia. Numbers there do not tell about transonic drag rise or supersonic limits of control authority, either.
The Suchoi 27 is a large aircraft and has some compromise built in. Data shows that it is on par with the F-15 with disadvantages at higher speeds. It has advantages in low speed maneuvering.

I do not use wikipedia as a reference , can you be less vague please “some” and “advantages” are less than helpful.

I thought The Flankers had been flown with external stores and fueled in response to comments like yours and were able to perform the same routines?
I agree that Airshow routines dont tell you much but its a fact that the flanker in most of its versions is unmatched in WVR by anything the US is flying now except the F22.
With the addition of the ER and ET versions of the R27s + R77 it is also a formidable BVR aircraft unmatched by all except the F22 and APG79 equipped F18s.
From what i have read this forum is full of either US Fanboys who simply will not entertain the suggestion that the Russians have any technology that even equals theres, or the polar opposite.

All of the above is subject to so many variables it means nothing on its own anyway, pilot skill, training, fuel levels, Awacs and general situational awareness etc will determine a winner more than the fighter.
