Dont remember where I read it. Someone speculated on it. They are built light for speed, without "unnecessary armor". This time it was necessary. What ever happened, it sure doesnt look like a cut and dry accident, thats for sure.
Air craft carriers are no lite weights and their speed is classified. I do know they can do 60+. The Enterprise 45 years ago could leave us standing hands down. With today's
Nuke ships there's no need to scale back.
