The raw performance of individual Russian systems seem ok,if not good.The problem is with their “brains” & their level of integration with other systems.Look at the case of this missile-the problem seems be with the sub’s gyros,which are responsible for loading targetting data into the missile.A variant of this missile serves on Indian frigates-those seem to working well.
It doesn’t matter. The sub and the missiles all came from the same source and should have been tested by the maker prior to delivery.
I doubt that the shipyard even bothered.
