What is different about this rocket from any other? It would seem to me they are all hypersonic and any rocket that can carry a weather satellite can carry a nuke. I like fear porn as much as the next guy but it has to at least be real fear.
The major difference is broad crossrange maneuverability. A ballistic missile warhead is really just that, ballistic. You can generally tell where it’s going from the moment it comes over your radar horizon - it’s like throwing a tennis ball, its ability to change course is relatively limited after warhead separation. A hypersonic glide vehicle is more like a space shuttle in terms of ability to maneuver on the way down, if not better. It can also have a very nasty terminal low altitude final delivery profile - running Mach 3+ on the deck.
