Since the Air Force is announcing it's existence, the SR-72 is obsolete. Same pattern as the SR-71 and before that, the U-2. Should be on the air show circuit in a year or two.

All that's left is to speculate at what replaced it...

“Should be on the air show circuit in a year or two.”

I sincerely doubt it, and I’d rather that the Air Force and Skunk Works keep it under their hats as much as possible, and that if they were to say “If we told you, we’d have to kill you”, they’d be saying it with all sincerity.
