Ok, here's the thing: China's main strategy, and the strategy being touted by most of her admirals at the time, was that the "big guns" like battleships and destroyers and the like, would win the war. They didn't realize the power they had with air power, until it was found that the campaign in the Pacific was being won by airpower.
So, it might show that even though the Japanese were actually trying to hit the carrieres (although I don't think this is the case), they went after the US's big guns because they thought a similar strategy/thinking might be employed.
If you think about it this also makes sense, because Nimitz had to devise a completely new battle plan for taking the Pacific (the island hopping strategy).
And Ford, I highly doubt that. It may have been a tiny part of the cause, but I doubt a very large one.
