Yea, as soon as I pressed the send button, I realized that I should have qualified my statement to early war. In fact, pre-war strategy was to separate the CV from battleships (the battle fleet) for their own protection from plunging fire from the enemy's battle fleet. In the later war years, the US was assaulting island chains which combined airpower for air superiority and tactical strikes, and battleship guns for shore bombardment. BTW the photo looks like a post war shot.
