F-16 Block 60 starts to really push the 4th generation classification
though.
It would probably fall under 4+ or 4.5

You are missing my point. There is no single approved "generational model".
Some folks consider the new aircraft just coming online (F/A-22, Rafael,
Typhoon, etc.) to be fourth generation, which would place your F-16 Block 60
in the 3.5 generation range. I have no doubt that others would claim that
the F/A-22 is the lone fifth generation contender at present. It seems to be
a case of different strokes for different folks. I doubt the folks at DoD
care enough either way to specify/define what makes up the various
generations of fighter evolution. Why bother, when it is of little value and
is extremely subjective in nature? Trying to develop half-generation steps
just makes it even more cumbersome and subject to debate.


Yes but dont forget, people here debate for no reason at all than for just to
debate

I think the generation system I have heard used most, would put F-22, F-35 as
5th..
