you can disable it with one with blasting off the rudder and props. I think the carrier would be in serious danger if it was hit with 5. BTW: China has carrier killers, I am not sure if they are worth a shit.
The surface Navy does some really stupid crap. Primary units DDG’s, Cruisers and CVN’s all have noise abatement gear which works really well. Then once every 4 days a fleet oiler comes around that is louder than all get put and gives away the store. I hope that situation has improved since I was in the fleet.
