Agreed. There are definitely a few areas and examples where Russians over hype their stuff (just watch combat approved, love the show but whoa man) but in a particular number of domains their kit is indeed hard to over hype. Remember delving pretty deeply into some of their jamming and surface to air missile complexes and damn. They are legit good in these and some other fields.Well i have never seen such accelleration after the booster launch kicked off.. never!
So this is a new rocket engine, even if it uses older chassis or what not.
Impressive for the sheer size of it.
Yes i am aware of the overhype of said S-500.. but if you think about the current budget(around $60Bn) the last two years, the Russkies sure does make prospects/concepts turn into Complex's.. how they manage to do this idk
Look a little closer. The missiles containers are virtually identical. They just look bigger because the rack that holds them is a little different.
There is already Antei-4000, which is exactly what you are describing. Seems like missile tubes are considerably larger on this one:
