I believe the hypersonic missile launched in Ukraine was a standard ballistic missile launched from an airplane and is really nothing that advanced (the article mentions this technology was invented in the 80s). Hypersonic glide vehicles are more of a question mark. Russia claims to have them, but their ability to reliably deploy them is unknown as they’ve never been used outside of tests. The U.S. is working on its own HGV, which should be superior in many ways. This attempt at achieving superiority is also what’s leading to the lag as more technical problems need to be worked through.
