Hypothetical capabilities of Russian weapon systems, that have never been proven in practice, cannot be taken seriously at this junction. Moreover, even the existence of such systems, like the Armata tank and hypersonic missiles, is in doubt.
Our war games don't seem to paint a very rosy picture, and we barely have any manufacturing capability left.
Sink a carrier or two and what are we left with? Nukes, long range bombers, airbases... could we even mobilize enough to defend and hold Europe if the reds invade?
Also, a huge problem with modern Russian hardware is that it’s largely vaporware. That’s why they are using all that USSR-era equipment.
