The Russian "hypersonic" missile is just the upper stage of a short ranged ballistic missile launched from an aircraft. Its just an existing weapon with more steps. The Chinese hypersonic weapons everyone is worried about is a boost glide vehicle. Basically a ballistic missile with a hypersonic lifting body as its warhead as opposed to a blunt body RV you usually see. This makes it more maneuverable and potentially harder to hit. The weapon the air force tested today is similar to that but meant to be launched from bombers instead of ground launched. The actual scary ones are hypersonic cruise missiles. Nobody has fielded one operationally yet. But the US is by far the furthest ahead in this technology. In march they had a successful test of HAWC the Hypersonic Air-breathing Weapon Concept. Scramjet powered cruise missiles like HAWC are more dangerous than conventional ballistic missile or boost-glide missiles because they actually fly. And therefore can do the things normal cruise missiles like Tomahawk can do. They can take circuitous routes. They can change their altitude. They can fly somewhat evasively. They can fly to an area and pick targets of opportunity. And other things. Why does it matter? We've gotten much better at shooting down conventional cruise missiles. A few years back an Arleigh Burke destroyer had a number of Chinese built subsonic anti ship missiles fired at it by Houthi Rebels. It shot down every single one of them. These missiles are comparable to the Neptunes that recently sank Moskva in terms of performance. So modern warships aren't as vulnerable as Soviet era antiques. You need better weapons to kill them. hypersonic cruise missiles are much harder to intercept. Boost glides are of dubious utility in my opinion. |

So your impression is not correct. The Russians and the Chinese actually are much further along for all classes of hypersonic missiles.
