This one? Something similar may as well appear at some time.
I'd like to see what battleships can laugh at 6 (trials) and 4 (combat) RPM. If we're talking about Kirov - their main problem was barrel life, especially for first batch of guns, which had no liner. And it wasn't a light cruiser.
Though, it's a topic for different and separate discussion, if you're intrested.
