Im no expert but all the shows and movies ive seen on the military channel and other channels about WWII have never shown anyone moving and hiding the cv. What would have happened if we did that at midway or Pearl ?
Hiding the cv just takes another yet fun aspect out of the picture so all we have left is hos and hordes.
We also didn't hand over the keys to our CV's just because their port got bombed so it's not a very effective analogy. I don't condone CV hiding, I think it's a bad practice, use them, take the port back, etc. That being said I don't see how one person's bad behavior is a suitable justification for more bad behavior.
Historical CV operations, were always governed by risk/reward. Especially early in the war, the Doolittle raid was launched much earlier and further away than planned because they thought the task force was detected. The navy pulled it's support from the Guadalcanal invasion after only a day or two in the area, effectively stranding the marines there w/out their full compliment of supply because of the risk of air attack, an early raid on Rabaul was likewise scrubbed because the CV was detected early. The stakes were just a wee bit different back then.
