Lost in combat and lost in testing during times of war/combat are two completely different things. Yes, an F-22 crashed last year, but it was not on combat operations. Same goes for the B-2 that crashed on Guam last year.

To my knowledge, we haven't lost an aircraft to an enemy since the F-117 downed in Serbia in the 90's.

We never lost an F-15 in Desert Storm.

F-22's are operational, but the program is wrapped up so tight that it wouldn't be feasible to assume that they have seen combat.

BOTTOM LINE:
If you weren't in the military at any point, please refrain from commenting because BS stats and 'facts' bother us more than anything else.
