Performance standard: 60% internal fuel (5000 kg), 2 aim-120 missiles, 15000 ft, M0.8.

Threshold: 4.6G at M0.8

Demonstrated performance: 4.95G at M0.8 (F-35 240-3 configuration)

4.95G at M0.8 corresponds to 11 deg/sec. Not a good looking figure?

This is because F-35 is carrying too much fuel. That is not fair.

Note that Mig-29 uses only 1700 kg as performance standard (1700=3400*50%). For the same afterburner time, a F-35 needs about 2000 kg fuel (fuel consumption = SFC*thrust*time. Since most military turbofan engines have similar SFC of about 1.9, fuel consumption is proportional to total thrust.)

With 3000 kg weight reduction, the total flying weight gives a factor of 16000/19000=0.84. Since the normal load factor is inverse-proportional to weight, the turn rate will be increased by 19%. Which is 13.1 deg/sec at M0.8, 15000 ft.

F-35 is already among the top performer even we don’t consider the turn rate increase from M0.9 to M0.8. We haven’t considered the fact that 2 aim-120s are definitely heavier than 2 infrared missiles neither.

It is safe to assume that F-35 could out-turn its major adversary, Su-27/30 families, for the fuel of same afterburner duration
