I keep hearing this and I’m not saying you’re wrong as it very plausible but have you seen any good sources at the root of this?
Hi.
Jane’s Defense Weekly is a good source for ship capabilities and armament.
Plus, Soviet doctrine stated the first use of nukes, and this ship (and subs) have the capability.
Do I know for sure, no. Would I bet on it, yes. And give odds.
