North Korea successfully test-fired a new hypersonic missile, state news agency KCNA said on Wednesday, the latest step in a plan its leader Kim Jong Un described as aimed at using solid fuel to power missiles of all ranges.
It seems that a year ago they managed to shoot down one kinzhal missile. From my understanding, they shot it down in its "final approach"/maneuver to target stage, which happens at subsonic speed.
They never shot down a Kinzhal, those sources you linked are basically Ukro propaganda cope. Russia has and continues to use hypersonics in Ukraine which neither Ukraine's remaining legacy Soviet S300 nor their Western provided Patriot systems (multiple of which have already been taken out by these missiles) can shoot down.
But Kinzhal isn't a "real" hypersonic missile because it doesn't maneuver and change trajectory while at hypersonic speeds. That's why it is possible to intercept it at the last moment when it is on its way to the target.
I was also skeptical about their claims, but I am inclined to believe them because they say they shot down one a year ago. A situation where stars align, similar to Serbs shooting down a "stealth" F-117A in 1999 using a Soviet S-300 system.
Russia hasn't used their whole arsenal in Ukraine, they haven't used their "glide" hypersonic missiles, the ones that maneuver while hypersonic and can't be intercepted by Western AA. Those are the ones that can reach EU capitals within 5 minutes to deliver a nuclear warhead.
Governments have overstated the effectiveness of missile defenses in the past, including against Scuds. During the first Gulf War, the United States claimed a near-perfect record in shooting down Iraqi variants of the Scud. Subsequent analyses found that nearly all the interceptions had failed.
Intercepting a missile is not the same as an airplane that flies at a much slower speed and a much larger target.
Actually, the F-117A was shot down in part because when its bomb bay doors were open it can be seen on radar, and Serbs knew where it was going to be flying because the bombers followed the same flight path on every run.
I never said Patriots can reliably shoot down kinzhals, I said that it is possible to get a lucky hit when the kinzhal is on its final approach to target, when it flies at subsonic speeds.
It's good to be skeptical of any claims that are extreme, and "Kinzhals have never been shot down" seems like a strong claim, like you would expect by simple random chance that one might eventually get shot down. However, I distinctly remember the 'Kinzhal shootdown' story, so I present you these images.
This is what a Kinzhal looks like strapped to a Russian plane This is the 'shot down Kinzhal' presented to the media by a high ranking Ukrainian official (I forget his name) Bonus: Another 'Kinzhal' Ukraine claimed to have shot down two months later
