The organization of high-tempo air operations from…

““The organization of high-tempo air operations from carriers remains an extremely challenging proposition even today, but in June 1942, the Japanese were world leaders in this field. Their fleet carriers would typically hold about 90 aircraft, confined into a very tight space. There were two hangar decks, with lifts connecting them to the flight deck above. Japanese ground crews were very well trained, with the result that they could turn around aircraft much faster than their British or American counterparts. Nonetheless, these were crowded ships, and they were already coming under attack from the Midway-based American aircraft. Furthermore, in addition to switching armament for Nagumo’s reserve bomber force, the crews were maintaining a rotating force of covering fighters. There were always Zeros on deck waiting to take off, being refuelled, or just having landed. Hoisting heavy torpedoes into the bomb bays of the Kates was also a very skilled operation that only specialist torpedo armorers were able to undertake. In short, this was a recipe for delay and confusion, even given the superb quality of the Japanese ground crew, and as Nagumo changed his mind twice in the span of less than an hour, the issues the Japanese faced on the carriers were exacerbated. ””
