That definitely seems to be the real story on the destruction of 3 Patriot systems.
They were not destroyed, only damaged. They were operational again a few hours later.
I would lean toward the possibiity that the Patriots can be effective if around 30 are launched against the Kinzhal to stop it by chance or luck.
That is known as a "missile swarm". And that would actually be hard for Russia to do as it would be a major air operation involving a dozen or more attack aircraft to pull off (more than likely over 2 dozen).
The main platform for the Kh-47 is the MiG-31 Foxhound. And it can only carry one of those.
This then leads to the question of what will be the outcome if 30 Kinzhals are launched at once, carrying nuclear warheads.
Well, at that point it is stupid for multiple reasons.
First, the moment that happens it is no longer a war, it is a nuclear war.
Secondly, there are a lot more systems that are far more effective at putting a nuke on target than a Kh-47.
My reason for my guess is that there's no way it can be denied that America is franticaly attempting to develop it's own hypersonic weapons. It's not possible to hide that!
Maybe we can ask a military expert on missile technology?
Sure, the US looked into it back in the 1970's. Actually did testing on it, and ultimately discarded it as a rather silly idea that had no real purpose.
I can only imagine you do not really know what "hypersonic" missiles are. They are not traditional missiles, they are simply air launched ballistic missiles. They are not something like a high speed TOMAHAWK, not even close. They literally are a missile that is launched from a plane, then after reaching high speed climbs to high altitude before releasing the warhead, just as in the case of any other ballistic missile. They then fall from a high angle, no different than the V-2 of WWII or the SCUD of Gulf War I and II.
And there is no need to "hide", the US did it back in 1974. And they do play with the idea on occasion, but I can't see the US ever implementing one for multiple reasons.
First of all, if we ever bring the INF treaty back they would have to be destroyed. Therefore that would be a waste of money.
And secondly, the way the missiles operate. Hypersonic flight can only occur at very high altitudes. And that makes the very easy to detect from extreme ranges. The US has always preferred to operate its penetration systems (manned or unmanned) with a "low and slow" flight profile. That is why although the TOMAHAWK and B-1 can operate at high altitudes, the penetration profile for going into hostile territory was always to do it as low to the ground as possible to prevent detection and interception. One reason why it is so hard to intercept either is that they are so low that there simply is not enough time for most air defense systems to react to them before they are gone.
