Seems to me that Russia currently only has 1 of these missiles. But it may have several. If production gets under way, nobody will be able to stop Russia.
Putin prepares new hypersonic 20,000 mph Avangard 'meteorite' missile...Russia today revealed chilling new footage of its 'meteorite' hypersonic missile Avangard being readied for combat in yet another nuclear threat to the West.
Footage shows the weapon - which is delivered to targets at 27 times the speed of sound - being installed in an underground launch silo in the Orenburg region, southwest Russia, near the Kazakhstan border.
The missile with a hypersonic glide vehicle is fired outside the earth's atmosphere before striking any target in the world in less than 30 minutes, claims Moscow.
Like other Russian hypersonic missile systems, Vladimir Putin claims the West has no means to stop it.
Today's emplacement of the 20,000mph (32,187kmh) Avangard beast follows three consecutive days in which Putin has showcased the deployment of new Yars nuclear missiles in Kaluga and Tver regions.
The Kremlin revealed Putin had spent all of Friday with his military commanders in discussions over the war in Ukraine.
The day saw the unleashing of dozens of missiles on Ukraine - many of which were successfully shot down by Kyiv's air defences.

You have an interesting style of writing... for example "when Trump wins the elections", when "Rusia wins", when the RF develops this weapon, when... But the "when" and the "ifs" are just wishful thinking.
In this case the latest stuff is the "unstoppable weapon" myth. Look, the RF already has the technology and the ability to use missiles that range from very difficult to nearly impossible to stop, but that does not matter because the can produce a tiny amount of them, some fail spectacularly and they are more expensive that most targets out there. On top of that, they are a weapon of terror, but will not win a war - unless used in quantities that the RF cannot produce.
Why the heck do you thing they are using IKEA drones?
But here is where your own thinking backfires on itself. If Russia is so weak, why hasn't the US military simply gone in there and broken her apart... especially since they have all that Nato around there in Europe?
Something like almost $100 billion has gone US to Ukraine so far. And Biden and Congress are promising another $38 billion in the coming weeks. How many more billions is it going to take
before the US destroys itself with inflation before they make Ukraine strong enough to begin to fight Russia?
With the break-up of the USSR in '91, there was the promise that Nato wouldn't push further in the direction of Russia. So, Russia was dumb enough to trust that, and to go into somewhat of a bit of hibernation. The US is waking her up by slapping her with Ukraine... like a hibernating bear might get pestered by a squirrel.
You don't want to wake this bear up... if you know what is good for you. Let her sleep. Live and let live. Trade and let trade. But don't wake the bear up.
