Actually the US has worse wind tunnels for hypersonic testing than either Russia or China. Back in the late Cold War period the Soviets had the most advanced wind tunnels and they were all in the territory of the current Russian Federation. You have to see the Russians got their SST operational and the US never achieved that.

That had nothing to do with technical ability. Hell, the US built and tested TWO engine types for it. (Did you know the NK-32 engines on the Blackjack are only the 3rd most powerful afterburning engines ever built? Both the P&W JT-17 and the GE4, built and tested for the US SST, were more powerful.) The US realized (as history proved) that the SST was either a dead end or an idea before it's time, and killed it. Neither the Concorde nor Tu-144 were economically viable.

The technology used in the Tu-144 paved the way for the Tu-160 later on.
The NK-144 engine used in the Tu-144 was developed into NK-22 used in Tu-22M.
These were the first bombers Russia developed which had enough range to hit the entire continental US.
Tu-22M with one mid-air refueling and Tu-160 on internal tanks only.

When word came out of China's hypersonic developments after the US's Prompt Global Strike was cancelled effectively ending the US's hypersonic program, the naysayers said China didn't have any waveriders. Well China now has the only one that's been tested. No word in between of its existence except on paper so I wouldn't speculate what China doesn't have or isn't working on.

Df-zf is hgv not a waverider.

Ah that would be my mistake in the semantics. I assumed waverider can be powered or unpowered and glide vehicles are a subset of waveriders but it seems the universal(not agreed upon) definition for waverider is powered and makes use of propulsion.

The semantics between waverider and boost glide us poor though. You could technically have boosted hgv that is propelled and makes use of aerodynamic lift but there's no boost waverider group even though such a thing can be its own.

So Xiamen unis project makes use of "dual wave riding" but is unpowered. Df-zf is boost glide but may also make use of shockwaves, no one knows much about df-100 here except that it's powered. The aircraft is unknown. The global ranged flight however is most likely a waverider if it flew within the atmosphere and around the world at nearly mach 20 avg speed.

JTF17 that is. (J58 on the left. JTF17 on right.)
