That alone tells me that they're budgets screamers. I've never subscribed to a weapons system that never had a live test to work. Even Chinese ABMs have tested themselves against incoming rockets and this anti-carrier weapon never even hit a ship in open waters. So, colour me a dessenter.
Aside from that, again, 60,000 Russian rounds per day concentrated in a small front, smaller than Taiwan. How's that working out for the Russians?
