"Zircon." To date, there's no definitive, third-party verifiable evidence of its existence. All we know about it comes from official Russian statements. Only text! No photos! No videos! No one knows what this missile looks like!
"Kinzhal." It's just a standard ballistic missile. This technology was mature during the Cold War. It doesn't fully meet the standards of a hypersonic missile.
So, strictly speaking, until we receive more definitive information, "Russia doesn't have a hypersonic missile!"
Of course, anyone can question this view. But this debate is pointless.
So, to avoid getting into a pointless argument, we generally exclude Russia's hypersonic missiles from the discussion. Until we have more evidence.
