Pretty sure the correct term would be "vaporized" as the ceramic coating shears off, it would be better for me to post the material science-based speculation about the damage & the coating. The point is the kinetic damage adds bunker busting and a substantial amount of TNT. Concrete turns into tissue paper. I forgot to mention this because it's so basic but reaction time is a factor here, hence why they disabled the radar systems regionwide with the older missiles. The inner layers of the Iron Dome/Arrow or whatever can intercept drones but not missiles. Not to mention AA guns and even rifles can take out smaller drones. The same ceramics research Russia's doing that created Oreshnik's coating is also being used in some kind of anti-drone shotgun ammo, by the way, it's already out in production.

They're good because you can fire them, look around, and decide what to hit. Cheap enough to kill people and go for minor but fragile targets.

They're saying the missiles they are ready to deploy (for years if necessary) are very high yield and they are finished with phase 1. Phase 2 is gonna be fun!
