f35 can't effectively use it's stealth because it can't attack enemy while remaining hidden from long range.
Why Rafale fanboys have to badmouth F-35 in order to look good? That insecurity is very evident in this “Rafale thread” where most talk is about how “bad” F-35 is!
Some basics of stealth: (also take some time to see the image above and look at the ranges. Also, the detection range is for a maximum-power, narrow-angle search. In conventional search mode, the detection range is down by 50%.)
It sounds like Rafale is somehow made ”almost” stealth by making fanciful claims. In BVR combat against a true 5th Gen stealth aircraft, these legacy fighters will never know what hit them.
Here’s some declassified info:
The RCS of 1 or 0.1 m2 (which Rafale claims) doesn’t really matter to modern airborne radars. Even 0.05 is too much. Because even at that level of stealth, targets can be identified at max launch range of BVR A2A. Only exponential level of stealth can change the BVR combat.
The F-35 RCS is compared to a “golf ball” and the F-22’s to “a marble”; these objects have RCS of 0.0013 m2 and 0.0002 m2, respectively. That is exponential growth in stealth and for each decimal increase, detection range goes down by ~40%. (0.1 M2 RCS of Rafale will get detected at over 100km by Irbis-E and much earlier with AESA). So, in order to launch A2A first without risking passive engagement, stealth must be in 0.001 M2 range.
The meaning of all this is that F-35 doesn’t need very long range missiles or afterburner use to sneak up on unsuspecting 4th Gen fighters. It can get really close and fire within no escape zone of AMRAAM or even Sidewinder. The only time Rafale or Eurofighter can detect F-35 is when bay opens to fire the missile- too late.
