It's hard to believe it's that old. It filled a void but I think it has a hard time finding a niche nowadays especially with the new fighters hitting the skies and the B-2 handling the stealth bombing. But hey, I don't know crap about the air force and their aircraft uses... . I'm just speculating.
It's always interesting to see what Skunk Works puts out there... (even if it takes us 10 years to find out about it)...
