US Navy is unbeatable - it has about twenty times what any other Navy has in carriers alone. If one of them were sunk by a Russian submarine that got through the defences - unlikely - look what they'd have in reserve.
I mean - 10 - yes that's 10 Nimitz class carriers at over 100,000 tons each and another 9 of other types of carrier.
All the following carriers do not exceed 70,000 tons ...
What has Russia got?
1 carrier that has gone back for a refit after a history of breakdowns and arrestor-wire problems.
China
1 - maybe ready soon.
France
1 Carrier
UK
1 built - waiting for planes - and 1 on the way.
The rest of the world?
All relatively small old Cold war era built stuff or even WW2 hand me downs!
