Russia has hypersonic missiles that work. The US doesn't have that. Russia has status-6 sub weapon that can take out an entire carrier fleet (some say a coastal city with nuke but I don't think that was the purpose). Russia is far more advanced in operating in the polar region.
Didn't they lose a third of their black sea naval fleet? How's the polar region going to help with that?
Oh no, you are right, they absolutely are losing in the Black Sea. There is no defense against drones on the surface of the water, during chop, at night, coming in packs. I don't think any country has a defense against that yet. It's a very interesting time from a war-technical point of view.
That would depend on what you consider working, several of them were shot down by the patriot system in Ukraine and the patriots there aren't even the latest version of the system, I'm by no means claiming that those missiles are useless or something, but they are not the wunderwaffe the Russians claim it is
