The whole point of a stealth fighter is not to get into gun fights or WVR even. I don't even see how a gun fight could happen given the missiles available today. Even if BVR engagement returns a zero, all-aspect, dual-waveband IIR homing missiles can take out enemy aircraft from far WVR and even near BVR well before a head-to-head pass and there's pretty much no way evading or decoying them.
It's like a sniper engaging in hand-to-hand combat, sure they train it, but for it to ever happen, his rifle and side-arm have to prove useless and his Situational Awareness (SA) has to fail big time and the enemy has to not have a gun too. How likely is that? In reality the last NATO gun-kill on a fixed wing aircraft was in 1982 and the even the last NATO dogfights (1991) pre-date the introduction of the AMRAAM.
So what we have here is a fairyland situation concocted for development purposes where the F-35 was fighting with both hands behind its back, its ankles tied together and its nuts strapped to its eyes, in terms of flight restrictions, cancellation of advanced SA, for-going the pre-merge engagement and prohibition of LOAL/HOBS/HMCS abilities.
Anyway, it seems a pilot logged into another forum and made some helpful corrections on the matter:
