Certainly, one is struck by how large an internal volume penalty is paid to have the rotary VLS systems. In that light, the lack of a Soviet Union-era counterpart for SA-N-7 is particularly unsurprising, given that the primary application of the system was on a ship that was already notoriously cramped.
Soviet VLS is just a simple evolution of old launcher, missiles are ejected from the magazine straightly, so it revolves like older one. Also revolved launcher have a small open on the deck, it's good for the armour protection and anti-NBC.
