Unsikable carriers?
I still have small scars from being shouted at by a USN admiral "Son, our carriers WILL NOT BE SUNK, so F%&*ing unsink it!!" (I'd put its flight deck unusable due to a list induced by a torpedo attack in the Aegean, during a CPX)
What really scared me was that right beside his backbone I think he believed his statement.
