I'am not a military expert but this makes sense:
So I think that China is really the international force to be reckoned with right now in terms of hypersonics.The United States has a multi-billion-dollar hypersonic research program that successfully tested two Lockheed Martin missiles in late July.
But officials have said the missiles won't be operational until next year.
Despite this, ASPI's senior fellow Dr Andrew Davies believes the US is still ahead of China and Russia in the hypersonic race in one important class of hypersonics known as "air-breathing" missiles.
"Air-breathing missiles are even more manoeuvrable because they're operating within the atmosphere," he said.

Putler sounds like Saddam Hussein...a typical dictator.
Putler has lost all his marbles. Does that little scumbag know what a decade(s) mean? Then again what can he really brag about.Russian President Vladimir Putin is bragging this week that Russia’s weapons are decades ahead of competitors.
