For close air support’s characteristic, i will add small radius turn.
Subsonic turn rate is important but it’s important too having a radius turn as small as possible to keep target in sight easily and reduce time between fire engagements.
For dogfight’s charateristuc, i will add fuel efficiency (not far from “energy management” you mention, indeed).
In dogfight particulary, the first to break combat cause of low fuel has few chance to stay alive.
In dogfight, you can choose to stay in a “draw” position, taking few risks cause you know you have more fuel or more saving fuel capabilities than you oponent. Waiting him to break then, following him to shoot. These two points(“last to break” and “draw as a tactics”) give some “comfort” in a pilot’s mind engaging a dogfight.

In dogfight ,if you dont have irisT which has very good defensive capabilities and 180 engagement, bith contenders die, even if an f22 would encounter a mig 21 with proper wvr missile: that is why has not much sense to trow a modern and expensive fgihter in wvr.

Don’t understand what you mean by “both contenders die without irisT type missile.
I was thinking about dogfight canon, maybe that why i don’t understand.
In a wvr combat before canon part, indeed, with same type of missile on both side, at the first crossing, the game can be equal , but if it comes to manoeuver just after, fuel efficiency and turn rate will be crucial.

That is an assumption that is at best untested. Seeing how WVR missiles achieved 60-70% Pk against largerly nonmaneuvering targets, I wouldn’t put much money into it.

R “Don’t understand what you mean by “both contenders die without irisT type missile.”
Very few missiles have 180 degrees launch window; iris t has also very high intercept ratio vs incoming missiles.

It’d be interesting to consider the possibility of maybe a single engined CAS aircraft as well.
As I’ve noted before, another possibility is a turboprop driven CAS aircraft, for the loiter time.
With BVR combat, I think that you will want to have an aircraft that is at least a decent dogfighter, in case you do get intercepted. Something like a tailess close coupled delta variant of the Su-27 like I’ve described before I think is the best compromise. It won’t have the transient performance of a smaller aircraft due to size and wingspan, but it will still be very lethal. You could also go with what the Eurofighter has done with the long arm canard (such an aircraft might be a hybrid between the Su-27 variants with their high fuel fraction and the Eurofighter), although you’d want to consider deleting the radar.

The latest F-35 report:

It’s comically bad. This would be amusing, were it not so tragic.
