Unless it is nuclear tipped, one torpedo is not gong to kill a 95,000 tonne CVN. If in the future navies are firing nuclear weapons at each other then most all of the cities of the earth would be nuclear waste lands. So who cares?
I didn’t mean to imply that it was a one-shot/one-kill torpedo, but that multiple torpedoes would be able to strike the carrier before it or its escorts could react and, if not sinking it outright, would so badly damage it to make it unfit for combat operations.
