The number of operational and spare aircraft above were not Junyo's intended strength but the latest known total based on actual to-date issued aircraft and known available aircrew; Junyo may have carried the 6th Ku aircraft because her air group needed heavy augmentation as there were simply no more available aircrew and no more new aircraft.
