Despite which US carriers are frequently "sunk" during war games.
All that protection didn't stop the Swedish diesal-electric HSMS Gotland seamlessly torp'ing the Ronald Reagan in 2005.
France pulled a similar score 2015, Canada "got" a UK carrier in 2007, IIRC even Australia's taken out a US ship or two in various fun ways over the years.
Diesel-electric subs seem to be the bane of carriers. I'm aware of Dutch, Portuguese and Swedish subs that have "sunk" carriers during exercises, and often together with a significant part of their fleet.
But I do wonder what the starting conditions for those exercises were. The sub's underwater range is limited (although Swedish subs seem to be better than others) and the have to come up every once in a while, at which point they're vulnerable. There's plenty of places to hide near coasts, but I can imagine that on the open ocean, it might be a lot harder for a sub to get close enough.
