High Expect,
Sorry I don't understand...someone has a weapon that'll sink a carrier. So what? There have been submarine launched torpedos around for a while that are probably up to the job.
There are also systems called SAMs. But we buy aeroplanes.
There are rifles and knives, but we train infantrymen.
There are far more weapons capable of knocking out airfields...but we're fine with that idea.
Anyway, you get the gist.
If your point is that against that adversary or that technology one had better have a cunning anti-satellite plan up your sleeve, then I concur. But that could be as simple as TLAM-ing the control shack...or sailing under a cloud. If your point is 'someone has found a way to sink a carrier so let's hang up our boots'...we disagree.
