“Taking all together, and admittedly operating with the benefit of hindsight, the “right” answer to Nagumo’s conundrum probably should have emphasized maneuver, offensive speed in preference to mass, and passive damage control. With fifteen minutes in which to act, he didn’t really have time to implement anything terribly fancy. But he could have helped himself immensely by immediately spotting every strike airplane in his hangars, whether they were armed or not, and launching them at the Americans. The sixty-four armed aircraft he had in had were perfectly capable of doing enormous damage to his enemy. And by emptying his hangars, he removed the single greatest danger to his carriers --- the presence of fueled and armed aircraft within them.”
