Thankyou PLA. I was inspired to look into this by reading the excellent Russian navy thread here, it occured to me that the Soviet Union must have been working on advanced naval radars and new ship designs when it collapsed and that with the renewed interest the Russians are showing in their navy and that others are showing in buying its kit, that a solution to their weapons/ systems situation needs to be sort. So I followed the principle that the western navys have been of producing universal VLS (Mk41/Sylver) and reducing the number of radars on a ship (Aegis/Sampson/Arabel). Combined with the fact that the Russians have so many missile types that some of them somewhere must have similar dimensions and hey presto.:D
