Well my post has been censored but it doesn't matter. I say it again (perhaps more politely) David Axe knows little about spaceflight and it is more clickbait than anything else.
As for the Daily Mail it is hardly better.

I think we are talking at cross purposes here as I was referring to the classified report that Aviation Week were reporting on.

Russia Is Building a Nuclear Space Bomber

Russia reveals hypersonic stealth bomber that can launch nuclear attacks from space: Radical plane could begin testing in 2020

I reacted to this post, more exactly to the links, which are pretty bad (a nuclear space bomber ? really ? powered by fairy dust ?)

Yet Another SCramjet powered plan.   :(

It just does not add up.

The Russians have an ICBM that can hit anywhere on the planet in less than 30 mins already. They've sunk a lot of cash into that and it seems to work alright.

As has been noted an X37b could carry a nuclear warhead in it's payload bay but why would it?

Ah so if Americans fail to get all of them in orbit then Russian bomber will finish the job by nuking all the landed motherships.
Now it all makes sense.

Classified Report On Hypersonics Says U.S. Lacking Urgency

Sounds to me more like a call for more money by someone frustrated at the current lack of progress..

After all, it wouldn't be the first time in the history of aerospace that "The Russians Are Coming!" evoked a response from those holding the purse-strings.  :P


Yeah like that time people complained about Sputnik just for money......

Or maybe there is a real threat that unbiased experts now recognize as a threat, after all it is very arrogant to doubt the advanced engineering and determination of both Russia and China to develop hypersonic weapons.

Historically the US has flown ramjet missiles to M5. It just took a stuck fuel valve and IIRC worked quite well (till it ran out of fuel)  :)

The problem with hypersonic flight is not that it can't be done, it's when people insist on doing it in the atmosphere and using a SCramjet to do it. If you're OK with using a rocket it's (relatively speaking) not that difficult. If you want longer range in the same package then ramjets can already do that with reasonable T/W.

Engineering a long range hypersonic missile using a conventional ramjet is within the current SoA. The toughest part is likely to be the structure and the TPS.

Skunk Works Hints At SR-72 Demonstrator Progress

DENVER, Colorado—Four years after revealing plans to develop a Mach 6 strike and reconnaissance aircraft, Lockheed Martin says hypersonic technologies are now sufficiently mature to enable progress towards a flight ...

http://m.aviationweek.com/defense/skunk-works-hints-sr-72-demonstrator-progress

Quote
However, Weiss hints that work on a combined cycle propulsion system and other key advances needed for a viable hypersonic vehicle are reaching readiness levels sufficient for incorporation into some form of demonstrator. Following critical ground demonstrator tests from 2013 through 2017, Lockheed Martin is believed to be on track to begin development of an optionally piloted flight research vehicle (FRV) starting as early as next year. The FRV is expected to be around the same size as an F-22 and powered by a full-scale, combined cycle engine.

Quote
“The combined cycle work is still occurring and obviously a big breakthrough in the air-breathing side of hypersonics is the propulsion system,” Weiss adds. “So this is not just on combined cycle but on other elements of propulsion system.”
The technology of the “air breather has been matured and work is continuing on those capabilities to demonstrate that they are ready to go and be fielded,” he adds.

I'd thought even a demonstrator testing at hypersonic velocities in the big empty of Area 51 is going to be noticeable?
