I think J8F should get IRCCM, preferably with a rating of 13.0, and of course it is not impossible to go to the 13.3 level.
29G would still be relevant If the 27er is made exclusive to It tho.
I agree that the addition of a new variant like the S would be better than the upgrade of the regular 9.13/9.12 but there are no signals of those coming soon and i still think the 27ER is overkill against poor phantoms

is su-27sk manual fine to use in a bug report
Supercruise is mostly related to core temp & exhaust velocity on military power.
On a prop the thrust drops towards nil as speed increases, but in a jet you’re only really worried about the exhaust velocity relative to own airspeed because the raw thrust increases with airspeed (until the airframe breaks apart, a little after that it falls off).
It’s not raw thrust or engine size.
Should be fine I think. At very least for J-11, but since it literally carbon copy of Su-27 I dont see any issues
Going off your comments I assume you are trying to make some sort of point that if the F-15 (or MiG-29 as you said previously) can’t supercruise then surely there is no way the Eurofighter can.
Well here’s a page from the Lightning F.6 manual (an aircraft from the 1960s) showing that it can accelerate to supersonic speeds without afterburner.
It’s almost as if one aircraft being able (or not able) to do something is meaningless when it comes to discussing what a different aircraft can or cannot do.

not exactly, because the su-27sk is roughly 200+ kg heavier, but ingeneral, yes
It’s actually in the ballpark of 500kg.
sheesh
its very early 1950s prototype could supercruise
Stinger, Mistral, and other MANPADS staring at this revelation

Supercruise as going supersonic, technically yes, most jets can technically do this at the right conditions, like a Lightning. EF2k’s cruise, but most pointedly F-22’s is relevant because it is faster (~1.4-1.5), which is the original meaning of supercruise.
F-15 technically can but that would be like arguing the merits of the F-106’s ‘supercruise’.
He did not go into the supersonic zone
Also, do not forget that the Lightning has a greater wing sweep
It very much does.
Per the Cambridge dictionary supersonic is defined as “faster than the speed of sound”. The speed of sound is Mach 1.0 and on both graphs it quite comfortable exceeded Mach 1.0 without Reheat

The lightning does not use a turbofan, aircraft with turbofans that efficiently supercruise tend to rely on a lower bypass ratio or suffer from excessive turbine inlet temperatures. The F-135 on the F-35 has to handle nearly 2,000 degrees C whereas the RM12 (F404) can get away with ~1,400C. Yes, the F-35 makes more thrust but it is more than 3x as heavy and makes only ~2x the thrust without afterburner. I am using the RM12 on the Gripen as an example because I do not know the EJ200 numbers off the top of my head.
Aircraft like the F-35 also needed higher bypass ratios to allow for the modified variant to drive the turboshaft vertical lift fan. The Eurofighter does not have such an excuse. Instead, they relied on a higher bypass ratio to allow for more efficient afterburner performance and to meet the performance requirements of the program in combat conditions. Climb rate was a huge one for them.
Other engines such as the F119 on the F-22 and the M88 on the Rafale use a much lower 0.3:1 bypass ratio, and they also have lower turbine inlet temperatures and reasonable pressure ratios. These engines have long lifespans and good dry thrust performance. The F119 for example has more dry thrust than the EJ200 does afterburning.

Regardless we have sources that state the eurofighter can Mach 1.5 super cruise though for some reason one person seems to believe he knows better and think it can’t super cruise at all
We do not know that it can efficiently supercruise. The data suggests this would negatively impact the lifespan of the engine compared to other designs which were made with supercruise in mind from the onset.

If I recall correctly supercruise was one of the design requirements for the typhoon.
