"I kinda surprised people thought the Moskva would survive anything. The US has demonstrated multiple times that correctly applied EW reduces the best missile air defense system to unguided rockets. "
Interesting post FP - but I suspect that both the British in the Falkland's and the Russians recently also had great faith in their ability to avoid a massive strike on a warship.
I think there are two problems - one is you don't know exactly how someone is going to fight a war until you get in the fight and secondly navies, because they have a relatively few, long lived and expensive platforms are reluctant to talk about losing any of them in a fight and so, when they do, the shock is that much greater. I'm sure the USN would do better than the Russian's but the opposition might be a lot greater than the Ukrainians have mounted at sea so far.
