I saw it fly at the Edwards air show a couple months ago. Absolutely the most amazing air show demo I've ever seen.
Unfortunately, it takes 30 hours of maintenance per hour of flying time, doesn't perform well in the rain, and the radar-absorbent skin is debrided by airborne particulate, such as sand. It's therefore never been used in Iraq or Afghanistan, not is it likely to be used in any real-world combat situation.
Shame. Hell of an impressive air frame.
