That would be interesting. I haven't a clue as to how they would even begin to get that to function as the resonance time was such that the propellant was out of the scram jet before it could burn.
NASA publicly did a scram jet run for several (7) seconds, but we had no idea how they were able to pull it off.

I am curious though. I always remember a couple of these guys came to my school on recruiting trips every year, and one of the things they always saying was that they were 50 years ahead in technology of where you thought they were. How amazing is that? It was 50 years from biplanes to Apollo. Now its 50 years from the SR-71, no telling what they have out there in the desert, or out visiting Cmdr Fravor off the California coast.

You know we have a drone in low earth orbit? We can put it anywhere in probably a fraction of the time a ground based asset would require

I think that’s what the big rocket motors are for You’ve been watching too much Hollywood. In-orbit assets (almost?) never use big rocket motors, except to de-orbit. A sub-orbital, mach 5+ asset has significant advantages over in-orbit assets.
It is very difficult to target a mach 5+ plus (adhoc) vehicle ops. Dunno if Russia or China has anything on the same scale as SBIRS.
