If russia did attack a country or NATO.(unlikely) the Kirov Class no no counterpart. To sink it they would have to use subs such as Virginia Class. In which case the kirov has ASW to protect it. Im not saying its unsinkable but it could tank out at least 1 or 2 us missile cruisers before they could take it down. U ask me thats a pretty good ship. If it would have seen combat we could better avaluate it. Hey, maybe it will oneday.
