All online military enthusiasm made combat simulations of F-35 vs Su-35, such as the following, make one critical mistake:

They assume that the military speed of F-35 is very slow and thus could not outrun Su-35, making the hit-and-run tactic useless.

Given the most updated military speed of the F-35 is Mach 1.2, Su-35(with AA loadout) needs briefly engage in A/B to catch up with F-35. Making its infrared signature more obvious. Su-35 could be easily picked up with DAS.

The lock-on-after-launch (LOAL) capability of aim-9x block2 allows it to turn 180 deg (a reversal) and shoot bandits in the rear hemisphere of F-35. There is one more thing to notice: when a missile is launched to tail-chase a bandit, its effective range is greatly reduced. Even R-77 has a range of 5 km at low altitude:

(This is the case when the laucher and the target are all @ M0.9. if both are at higher speed the range will shrink more)

However, when a missile turns 180 deg and engage a chasing bandit, it actually engages the target head-on, resulting in extended range. If my memory serves, aim-9x block2 successfully engaged a target 10 miles (16 km) away and behind the launcher, in early 2013.

In this scenario, aim-9x block2 out-ranges R-77. That is a fun fact.

So when a F-35 uses the hit-and -run tactic against two Su-35s, the chasing Su-35s could be picked up easily with DAS far away, and will be engaged by aim-9x block2 well beyond the range of R-77.

With supercuise+DAS, one F-35 could solo at least two Su-35s without exposing itself to any danger.
