it often surfaces up, but this isn't the case.
If you're reliably undetected until X, you come exactly to X. I.e. the original air combat stealth attack - against an unaware opponent. If that X allows you to slip past opponents' sensor envelope(including canopy) - ideal; then you're absolutely invisible.
I.e. ideal is well-proportioned, near point blank, unavoidable shot with zero reaction time. Which, of course, is better done with BVR weapon(more utility, faster, more energy, more warhead).
Stealth is achieved at a cost of directly sacrificing ammo depth and weapon unit size. But ideally it increases Pk to a degree unachievable by an outsized external weapons, carried in larger numbers.
Even more so in a world where most fighters don't emit until really necessary, and are anyway limited in their 720 awareness. Like that Iranian F-4/22(phantom with raptor underneath).
BVR is for those who either are outright visible, or unsure how truly invisible they are("blinking").
Caveats: what those "100" mean.
Like, yes, something like irbis can torch you out in the sky in concentrated search.
But by itself, it can't really find you; someone needs to point where to search first.
Or LPI modes, used in hostile situations. Both range and probability drop massively with them.
Then there are edges of ESA scan cones, then there's clutter and situations where data fusion can't help or even degrades the track.
Then there's effectiveness of most types of EW, which is directly dependant on what you're trying to hide.
I.e. in theory, scaled rcs reduction work(which is both expensive and time-consuming) is very unattractive bang for buck; go 100% or go home. In real world it works almost the opposite.
