They can and they do. Easily. All they needed was justification. They have it now.
They can't cope.
China currently spend close to half what the US spend for military.
Means any escalation in spending for defence can be outspend by China without any real efforts.
Russia still has same waggling room for spending, they can just simply keep the current level to force the US to keep up with the improving Russian AND chinese capabilities.
It is a match that very hard to win for the US.
Seawolf is competitor to first Yasen only. Los Angeles is superior to all others you listed.
Where you get this info? From a US patriotic fanboy?
The Seawolf was way more expensive than the Los Angles or the Virginisa ( not by small margin, but by 2-3 times more)
And the Seawolf is 20 years newer design.
What do you think ,what was the reason of the price difference? Golden toilet seats?
Los Angeles is a 60s designed sub.
The Akula is a late seventies design.
Actually, the reason of the Seawolf design was to keep up with the Soviet capabilities.
But it was too expensive.
The Vriginia is a dumbed down sub compared to the seawolf/akula/oscar or yassen , it wasn'tr designed to compete with these ships.
It is more similar to a nuclear powered Kilo than to an akula competitor.
China will not be breaking up anything any time soon. And even if they do Russian considerations will be completely irrelevant.
Stop expecting China to do heavy lifting for anyone.
China needs to break the Taiwan-South Korea- Japan chain .
As soon as it does that the US defence cost will dramatically increase.
Seriously, where you get your infos?
