MTOW - Old argument re capital ships. "the carrier can be taken out by a single missile or torpedo".....
That is not an argument not to have them. Yours is an all-out war possibility. When was the last carrier sunk enemy action? Around 65 years ago.....
Remember the Falklands would have been lost without Invincible. It operated of with sub/air/surface opposition threats.
Assymetric military engagements have been the hallmark of combat operations since Korea.
