Aurora - Secret Hypersonic Spyplane
Does the United States Air Force or one of America's intelligence agencies have a secret hypersonic aircraft capable of a Mach 6 performance?

Yes it does as of March 27th of this year.
the X-43a (scrammed) successfully completed a test mission (UAV) @ ~M7
(5k mph) for 11 sec before landing into the ocean.
A HUGE success for hypersonic research at Dryden.
