DARPA is working on some even faster, but we'll never hear about them. This one is at Mach 6 and one article I saw spoke of some almost double that. To crack up at that speed would be almost dust, fragments.

Envisioned as an unmanned aircraft, the SR-72 would fly at speeds up to Mach 6, or six times the speed of sound. At this speed, the aircraft would be so fast, an adversary would have no time to react or hide.

Thanks for sharing a background account on the SR-72 CPT Jack Durish which is the replacement for the legendary SR-71 Blackbird.
