The X-43 is a scramjet powered system.
The Blackswift (at least in the black project) is a low hypersonic turbine/ramjet combined cycle hybrid. You can credit a Pratt & Whitney/Lockheed effort on the engine development - of course that's just a rumor.

The hurdles that must be overcome for a MACH 6 aircraft are immense. No doubt it will have to be unmanned and very small. The navigation system would be fantastic and the recon systems will be far beyond imagination. If it were to carry weapons I would think they would be very compact.

I heard this just vaguely on the news today about this project but someone told me it goes mach 10?

No such info at this time - this is a black project and we're lucky to get this much.
I haven't seen anything about this mentioned anywhere except via a video (no text) on the Fox News website:
FOX VIDEO LINK
According to the (obviously out-of-date) information I've found, the Blackswift was rumored to be a super secret aircraft co-named HTV-3X that used a turbojet to reach supersonic and then a scamjet to reach hypersonic -- essentially a 21st century version of the J58.
Instead, the Blackswift described in the video uses pulse detonation engines, essentially a modern version of the V-1 buzz bomb engine. This engine requires significantly less moving parts and achieves much higher efficiency than a turbofan, and is technically able to go hypersonic without any kind of "dual-stage" engine.
The Fox News video is total braindead... anyone have a good source of technical information on this? I'm under the impression that the aircraft was only unveiled, B-2-style, TODAY.

Its more than likely has been flying for years and they are close to admitting it exist. We do know that something very fast was recorded over California years ago. It had sonic booms bigger than the space shuttle. I get the sonic booms every time it lands in Florida and let me tell ya they are loud.

I'm kind of new and everything, but is Intelgurl so revered here that as long as she makes sure to underline "extremely reliable" her source is trusted instantly?
