It out-throws not just the Slavas but upgraded NakhimovHonestly, if the Missiles in the back are of the S-400s variety, than i would say that this ship will be a good contender for succeeding the Slava-class.

Its a weird design but I quite like it myself
What I don't understand is reportage talks about 24* Kalibr & 32* Redut, neither of which is present on the model, which clearly has 16* each.
4* Uran (the funny thing in the front), a Duet & 2* AK-630.
I guess there could be a version with the Uran removed & an extra UKSK module instead?
Big question is what its got in the way of radar to guide the SAMs, looks like only a Positiv dome up top but could be something more powerful in the cone under it (like some recent French designs)
