Sort of? No more FA117 or SR71, but the B2 is still in service.
With a note that the SR71 was a semi-stealthy reconnaissance plane, not a bomber. I don't think it was actually that stealthy given that it was shot at regularly, it just flew high and fast enough to get out without harm.
Standard procedure was the zoom faster than the SAMs, but it did have some features that reduced it's Radar footprint. Also it helped that it was black during night missions ;)
From my understanding of stealth technology (which I must admit is fairly limited), the radar cross-section is merely reduced not eliminated completely. So they could still be detected it was just that the plane might be confused with other common interference. However, I assume in the case of the SR-71, the planes were flying so fast to begin with there was no confusing them for anything, despite of the reduced radar-cross section.
